Development of a Telegram Mini App (store) with CRM integration and Nova Poshta.

Budget: 15000 UAH Deadline: 20 days

Mykola, I can implement a Telegram Mini App specifically as a store, not a bot: catalog, cart, product variations, checkout, and a convenient admin panel for prices, stock, models, and colors. I will integrate with the CRM through a separate API adapter, so the system can be easily replaced without reworking the core. I will also connect Nova Poshta or pass the data to the CRM for tracking numbers. I have worked with Telegram interfaces, APIs, and e-commerce logic. Shall we discuss the stack and timelines?

Budget: 15000 UAH Deadline: 18 days

Hello. Regarding the project: we are creating a Telegram Mini App (a web application inside Telegram using the Telegram Web App SDK), not a bot with buttons - I want to clarify that right away. The catalog will have approximately 20 products with photos, variations (model, color, quantity), a cart, and a checkout with fields for name, phone, city, Nova Poshta branch, payment method, and comments. Orders will be automatically pushed to the CRM via API. The point you correctly highlighted is versatility: I will integrate with the CRM through a separate adapter (layer bridge), so that when the CRM changes, only the adapter will change, not the entire project. Nova Poshta - either direct integration with their API (cities, branches, creating TTH), or data transfer to the CRM if it creates the TTH, whichever is more convenient for you. Plus, a simple admin panel: products, prices, stock, colors, and models.

I will answer your questions. Stack: front-end - Telegram Web App SDK (JS), back-end - Node.js plus database (PostgreSQL or MySQL), integrations - Nova Poshta API and CRM via adapter. Timeline: approximately 2-3 weeks for this scope, more precisely after clarifying the CRM. The code, database, and all accesses will be completely yours after delivery; I will make the architecture modular so that functions can be added without reworking. Experience: I run my own online store, constantly working with the Nova Poshta API and order integrations, and I am building the Mini App as a web application on the official Telegram SDK. Please let me know which CRM will be on the order side, and I will provide the final timeline.

Hello! I am happy to develop a Telegram Mini App (store) for you with CRM and Nova Poshta integration.

I have significant experience in creating Telegram infrastructures and web applications:
- I develop Telegram Mini Apps using React + Vite + Tailwind CSS on the frontend and Node.js (Fastify/Express) on the backend. This will ensure instant loading and smooth interface animations.
- I have repeatedly integrated the Nova Poshta API (branch/self-service terminal selection, delivery cost calculation, automatic creation of E-document).
- I have configured data exchange with various CRMs (amoCRM, Bitrix24, HubSpot, KeyCRM) for automatic creation of deals/leads when placing an order in the bot.

My approach to developing this project:
1. A user-friendly product catalog with filtering, search, and cart.
2. Order checkout page: interactive selection of city and Nova Poshta branch.
3. Integration of a payment system (Mono/LiqPay/WayForPay) for order payments directly in the app (if needed).
4. Backend part with an admin panel for managing products, prices, and viewing orders.
5. Automatic sending of new orders to CRM.

I propose to implement the project for 10,000 UAH in 7 days. I am ready to start today. Let's discuss the details in a private chat! Expand

Hello!

I develop bots for Telegram using NodeJS. I have experience with Mini App. Write to me, and we will discuss.

Budget: 15000 UAH Deadline: 10 days

Mykola, for such a store in Telegram, it's better to immediately lay out a flexible architecture: a Mini App with a catalog, cart, order processing, admin panel, and a separate layer for integrations. I have worked with e-commerce and API integrations, so I can make the order transfer to CRM universal, and NP — through API or through CRM. I plan a modern stack with a frontend for the Mini App, backend API, and database. I can also think about scaling for new features.

Budget: 15000 UAH Deadline: 15 days

1. Which specific CRM are we connecting? This affects how much time will be needed for the integration.

2. Does the CRM create the shipping document for Nova Poshta itself, or does it need to be generated directly through the Nova Poshta API from the application?

These are the 2 key questions; otherwise, I can do it without any problems.

Budget: 27000 UAH Deadline: 7 days

Hello. I have extensive experience in TMA development. Do you have a ready design?

2. Timeline - 10 days
3. I suggest choosing the following stack:
Front-end: React
TypeScript
Vite
TanStack Query
React Router
Tailwind CSS
shadcn/ui
Back-end: nestjs, postgres.
4. I have previously worked with the integration of SalesDrive, Unipro. I integrated the API of Nova Poshta.
I am ready to discuss the project details further in private messages and start working. I would appreciate the collaboration. Expand

Budget: 15000 UAH Deadline: 7 days

The key here is the adapter between the store and the CRM. Replacing the CRM comes down to one new class, without rewriting the order logic.

Frontend on React with Telegram Mini Apps SDK, backend Node.js. For Nova Poshta, I will connect their JSON API (search for cities and branches directly in the order form). They return errors with HTTP 200, so we need to check the Success field in the response.

I will verify data from Telegram on the server using HMAC-SHA256; otherwise, a fake order can be sent under someone else's name.

Which CRM do you plan to use first?

Budget: 15000 UAH Deadline: 13 days

Hello! A Telegram Mini App store with CRM integration and Nova Poshta is exactly my profile; I create such solutions.

What I will do according to your specifications:
• Mini App inside Telegram: a catalog (~20 products) with photos, names, descriptions, prices, model/color selection, and quantity; a cart with quantity adjustment; checkout (name, phone, city, Nova Poshta branch, payment method, comment).
• CRM via API — I will make the integration UNIVERSAL (a separate adapter layer) so that in the future you can change the CRM without reworking the project, just as you want.
• Nova Poshta — integration with the NP API (search for cities/branches, and if necessary, create TTH) or data transfer to CRM if the CRM generates the TTH itself — whichever is more convenient for you.
• Simple admin mode: adding/editing products, changing prices, stock levels, adding colors/models.

I work through a Secure Agreement (Safe). The price is 15,000 UAH, with an estimated timeframe of 12-14 days.

Please clarify: which CRM is currently being used (to prepare the adapter for its API right away) and which payment method is a priority (online acquiring or cash on delivery)?

Good day! I created a Telegram Mini App-store (React inside Telegram + backend on Python) — with a cart, product card with variations by color/model, and an admin panel for editing prices and stock. I will integrate with the CRM through a thin adapter, so that later the CRM can be switched without reworking, and the tracking number from Nova Poshta can be pulled by the CRM itself or separately through their API. Please clarify right away: is the payment made within the app (Telegram Stars / LiqPay) or is it cash on delivery and payment upon receipt? This affects the cart scenario. I am ready to start, approximately in 12-14 days.

Good day, Mykola! 👋

I am ready to help you with the development of a Telegram Mini App (store) with CRM integration and Nova Poshta.

I have reviewed your task. The project is clear to me: it is necessary to create a store within Telegram as a Mini App with a product catalog, order processing, CRM integration, and the ability to work with Nova Poshta.

I have over 10 years of commercial experience in web development and practical experience in similar tasks. I have practical experience in developing Telegram Mini Apps and integrations via API with CRM platforms and delivery services, including the Nova Poshta API.

🔧 I will perform:
— Implementation of the Telegram Mini App (store interface and catalog of ~20 products with photos, names, descriptions, prices, model/color selection, quantity);
— Cart and order processing with fields: name, phone, city, Nova Poshta branch number, payment method, comment;
— Integration of order transmission to CRM via API with an architecture that allows replacing CRM without complete redesign;
— Integration with the Nova Poshta API or transmission of necessary data to CRM (depending on where the shipping document will be created);
— A simple administrative interface for adding/editing products, changing prices, stock, models, and colors.

✅ On my part, I will do everything neatly, without unnecessary complications, with attention to detail and convenience for further work.

🤝 I also always stay in touch with my clients and am ready to help with any questions regarding the project.

Hello, I will complete it quickly and efficiently. I would like to discuss the details in private.

Budget: 15000 UAH Deadline: 10 days

Good day. The task is clear, and the categories are chosen correctly. I will implement the Mini App as a full-fledged web application, isolated from a specific CRM, so it can be easily replaced with one click.

Technical stack:

Frontend: React.js / Vite + Tailwind CSS + Telegram Web Apps SDK (fast interface adapted for the Telegram curtain).

Backend: Node.js (NestJS / Fastify) or PHP (Laravel) — I will build a modular architecture.

Database: PostgreSQL / MySQL.

Implementation:

Store and Nova Poshta: A catalog with modifications (color/model) and a cart. I will input cities and branches through a direct API request to Nova Poshta with autocomplete (live search).

Universal CRM gateway: I will move the order sending logic to a separate service layer (Adapter/Repository pattern). When changing the CRM, the Mini App itself is not rewritten — only one configuration file is changed.

Admin panel: A separate tab in the Mini App that opens exclusively for your Telegram ID, where you can edit products, prices, and attributes.

Experience:
I regularly develop web applications, integrated the Nova Poshta API (directories, creating invoices), and set up order synchronization with KeyCRM and other systems.

Plan and deadlines:
10 days for frontend development, backend, Nova Poshta integration, creating a universal CRM module, and handing over all codes and access keys turnkey. Expand

Budget: 15000 UAH Deadline: 8 days

Good day, I can implement a Telegram Mini App as a full-fledged store, not a bot: catalog, cart, product variations, order processing, and an admin panel for prices, stock, and new models/colors. I will create a flexible architecture with a separate API layer for CRM and Nova Poshta, so they can be replaced without rework. I have worked with modern web interfaces and integrations via API. I will suggest the optimal stack and timelines after clarifying the CRM.

Budget: 27000 UAH Deadline: 35 days

The estimated cost for full implementation is from 120,000 UAH, with a timeline of 30-45 calendar days. The budget of 15,000 UAH may only be enough for short-term design or a very limited prototype without a proper admin panel and integrations.

Technologies - Telegram Mini App on React or Next.js, backend on Node.js or Laravel, PostgreSQL, a separate integration layer for CRM and Nova Poshta. This approach will allow changing the CRM later without completely rewriting the store. We have worked with CRMs, APIs, dashboards, online stores, order automation, and access roles.

We have experience in systems where not only the storefront is important, but also stable sales logic - products, stock, orders, statuses, integrations, admin rights. Here, I wouldn't lump everything together, as any new feature will start breaking the old ones. Yes, it sounds a bit tedious, but architecture saves money when the project starts to grow =)

From you, we need access to Telegram BotFather, API key for Nova Poshta, CRM data or its documentation, a list of products with photos, models, colors, payment and order processing rules.

Please clarify:
> which CRM is being used or planned
> is online payment needed within the Mini App or just the selection of the payment method
> should the Mini App create the Nova Poshta tracking number or will the CRM do this

Similar logical examples:
> https://business.ingello.com/prime-eva - online store and sales logic system
> https://business.ingello.com/carveli - retail, catalog, processes, and integration part
> https://business.ingello.com/forma-crm - CRM processes, roles, and automation

!!important point!! - if we are to create a proper Telegram Mini App, not just a bot with buttons, we need to lay the foundation, admin panel, integration layer, and error scenarios. We can start with the architecture and prototype stage, after which there will be an accurate estimate for full development. Expand

Budget: 15000 UAH Deadline: 7 days

Hello, I worked on a Telegram Mini App for a coffee shop network ☕✅ — a catalog with 15+ items, a cart, order processing, integration with CRM via API. The conversion of orders through the mini-app increased by 34% compared to the regular bot.

I have a question regarding the project: which CRM do you plan to use now — KeyCRM, Salesforce, or something else? This is important for planning the architecture of the universal API layer.

I suggest we get in touch; I will provide you with free technical consultation and we can create a development plan + I will tell you about my team!

Budget: 15000 UAH Deadline: 14 days

Hello. I will create a Telegram Mini App-store: catalog, cart, orders, CRM, and Nova Poshta, plus bot notifications and an admin panel. I will offer a step-by-step MVP and a clean API. The price is negotiable.

Budget: 15000 UAH Deadline: 30 days

Hello!

I have experience in developing modern web applications using React, Next.js, Node.js, and integrating third-party APIs. A Telegram Mini App is an optimal format for such a store, as it provides a convenient UX without the need to install a separate application.

Proposed stack:
* Frontend: React + TypeScript (Telegram Mini Apps SDK);
* Backend: NestJS (Node.js);
* Database: PostgreSQL;
* Deployment: Docker.

As part of the MVP, I can implement:
* a product catalog with photos, descriptions, models, colors, and prices;
* a cart with the ability to change the quantity of products;
* an order placement process with the input of contact details;
* integration with CRM via API;
* integration with Nova Poshta API or data transfer to CRM for automatic creation of shipping documents;
* an administrative panel for managing products, prices, stock, colors, and models.

I suggest implementing the CRM integration through a separate module so that in the future, the CRM can be changed without reworking the entire system. The same approach can be applied to delivery services or other external services.

Preliminary estimate:
Timeline: 4–6 weeks.
Cost: starting from 2,500 USD (final estimate depends on the chosen CRM and details of the business logic).

Upon completion of the work, you will receive the source code, database, documentation, and all access credentials. I can also provide further technical support and project development.

I would be happy to discuss the details and propose an optimal architecture for implementation. Expand

Budget: 14500 UAH Deadline: 14 days

Good day, Mykola!

I will create not just a Telegram bot, but a full-fledged Mini App store with a modern mobile interface.

I have experience working with Telegram Mini Apps, bots, and custom management systems. I will implement a catalog, product variations, a cart, order processing, an admin panel, and integration with CRM and Nova Poshta.

Stack: React + TypeScript + Telegram WebApp SDK, Django REST, PostgreSQL.

I will connect the CRM through a separate adapter — in the future, it can be replaced without reworking the store. Access to the admin panel will be secured by checking the Telegram ID, and user data will be validated on the server.

To ensure you see results right away, I will show a working prototype of the catalog and cart within the first 2 days.

Cost — 14,500 UAH.
Deadline — up to 14 days.

Please let me know which CRM you plan to use and whether the Mini App should create the shipping document independently. Expand

Budget: 15000 UAH Deadline: 14 days

Hello! The task is completely clear, and I am ready to develop a modern, fast, and scalable Telegram Mini App for you. Since my main technology stack is JavaScript/TypeScript (React + Node.js), I specialize in creating such client-server applications.

TMA is not just a bot, but a full-fledged web application inside Telegram, so the interface of your store will work as smoothly and beautifully as modern mobile websites.

🛠️ Planned technology stack:
Frontend (Mini App): React.js / Next.js + Tailwind CSS + Telegram Web Apps SDK. This will allow for the creation of a beautiful catalog, a convenient cart, and a fast checkout page.

Backend (Server part and API): Node.js / NestJS. This framework is perfect for integrating with various APIs and building a clean architecture.

Database: PostgreSQL or MySQL + Prisma ORM for reliable storage of products, categories, and order logs.

🎯 How your key requirements will be implemented:
Flexible integration with CRM: I will build the backend architecture modularly (creating a universal service layer-adapter for orders). All data will be standardized. If in the future you want to change CRM (for example, from KeyCRM to another provider's CRM system), only one small integration module will need to be rewritten, without touching the logic of the Mini App itself.

Integration with Nova Poshta: Instead of manual data entry, I will integrate the Nova Poshta API directly into the frontend. The client will see a convenient dropdown list with live search and autocomplete when selecting a city and branch. Then these clean data (CityRef and CounterpartyRef) will be sent to your CRM for automatic generation of the shipping document with one click.

Admin mode: An admin panel for managing products, prices, and stock will be integrated directly into this Mini App, but access to it will only be opened after automatic verification of your Telegram ID on the server (for security).

Scalability and security: The code will be structured and documented. After the work is completed, all source files, database settings, and access to hosting/server will be fully transferred to you.

⏱️ Terms and cost:
Project cost: 15,000 UAH. The price includes the creation of the database, development of the interface, admin panel, and setup of two integrations (CRM + Nova Poshta).

Completion time: 12–14 days (staged delivery: first the catalog and cart, then API integration and admin panel, finally — testing).

I have experience in web application development, integration with logistics. Expand

Budget: 15000 UAH Deadline: 5 days

Mykola, good day!

Telegram Mini App with CRM and Nova Poshta is exactly my profile, so I will immediately answer your 4 questions.

Stack: Next.js + TypeScript (a real Mini App inside Telegram, not a bot with buttons), PostgreSQL/Prisma, integrations via API.

Experience: yes, I create Telegram Mini Apps and have worked with CRM and Nova Poshta API — this is my regular job.

How I will build it:
— a catalog (~20 products) with photos, names, descriptions, prices, model/color/quantity selection;
— a cart and checkout (name, phone, Nova Poshta branch, comment);
— order transmission to CRM via API — I will create a universal layer so that the CRM can be changed without reworking the project (this is what you requested);
— integration with Nova Poshta: either direct creation of TTH through their API, or data transmission to CRM if it creates the TTH;
— simple admin mode: adding/editing products, prices, stock, colors/models;
— architecture for expansion, the code and access are completely yours.

Cost and timeline: approximately from 10,000 UAH, the exact timeline will be confirmed after clarifying about the CRM (which one) and the method of working with Nova Poshta. I am ready to start, I will send examples of Mini Apps. Expand

Budget: 15000 UAH Deadline: 12 days

Mykola, most here will write "I will do it." I have already done it. Open my portfolio and buy something in the live store.

Your specifications alongside what I already have working in production:
✓ Catalog with photos, variations (model, color), quantity
✓ Cart, quantity change, checkout
✓ City and branch of Nova Poshta directly in the checkout
✓ Payment selection and order comment
✓ Admin panel: products, prices, stock, colors, no code
＋ Universal CRM adapter: changing the CRM changes one layer, not the entire store

Timeline ~12 days, as the database already exists. 15,000 UAH, code and access are yours after delivery.

Question that depends on the adapter: which CRM are you planning, KeyCRM, SalesDrive, or something of your own? Expand

Budget: 27000 UAH Deadline: 25 days

Hello. I have reviewed your specifications. You think in business categories: moving away from button bots in favor of a full-fledged TMA and laying a flexible architecture for changing CRM is the right and mature approach. Our team specializes in such E-commerce solutions.

I am answering your questions regarding the stack and architecture:

1. Frontend (Client Side): React.js (SPA). This will provide a smooth interface, like in native applications (quickly adding to the cart, selecting colors and models without screen reloads).
2. Backend (Server Side): Python (FastAPI) + PostgreSQL. An ideal backend for fast operation and scalability.
3. CRM Integration (Your main request): To avoid "project rework" in the future, we will use the "Adapter" architectural pattern. The store logic will be separated from the CRM. If tomorrow you decide to change the CRM (for example, from KeyCRM to KeepinCRM), we will only need to rewrite one file-module, not the entire bot code.
4. Nova Poshta: We will connect the Nova Poshta API directly in the order form (React), so the client can select the city and the relevant branch from a convenient dropdown list. Then, this clean data will be sent to your CRM for automatic generation of the shipping document.

Admin Panel: To manage the catalog, we will deploy a convenient Web dashboard (admin site), where you can change stock, prices, and add variations in just a few clicks.

Regarding experience and demo:
We have extensive experience with TMA, logistics API, and CRM. The code and databases of our clients are protected by NDA. But to assess our level, just write to me - I will send you a link to our test stand (live demo of the store in Telegram) and a video of the admin panel in action. You will personally check the interface speed.

Terms, Budget, and Timeline:
All rights to the source code, database, and infrastructure will be transferred to you upon completion. Work is conducted in sprints through a Secure Agreement. Estimated budget: $1200 – $1500 (depends on which CRM you have chosen now). Implementation period: 20–25 days.

Budget: 15000 UAH Deadline: 1 day

Good day!
The project is clear; I have done similar things — Mini App stores with a cart and external integrations.
Stack: React (Vite) + Telegram Mini Apps SDK on the front end, Node.js (Express) + PostgreSQL on the back end, a separate layer for CRM integration — we do it through an abstract adapter so that the CRM can be replaced without reworking the catalog and cart. Nova Poshta — through the official API (search for cities/branches, if necessary, create TTH if the CRM does not do it itself).
Admin panel: a simple web panel for products/prices/stock/colors-models — separate from the Mini App so it does not interfere with the main functionality.
Timeline: approximately 3–4 weeks for all described functionality (catalog, cart, checkout, CRM+NP integrations, admin panel).
Access: code, database, and all accounts/keys — yours, without tying to me.

Experience with Mini Apps and similar integrations is available. I discuss the cost and examples in private messages.

Hello! Ready to discuss and complete your order.

Budget: 27000 UAH Deadline: 35 days

Hello! I have reviewed your technical task for the development of a Telegram Mini App store. The task is clear, architecturally understandable, and requires professional custom development rather than builders.

I have significant experience in developing complex web applications, API integrations (including Nova Poshta and various CRM systems), and I propose to implement your project on a reliable and flexible technology stack.

Planned technology stack:
- Backend and API: PHP / Laravel Framework 13. The most reliable base for e-commerce solutions with high performance.
- Admin panel: Filament PHP (fast, secure, and intuitive admin panel for managing the catalog, prices, colors/models, and stock).
- Frontend (Mini App): Vue.js / Tailwind CSS. It will provide a native-feel interface: fast animations, smooth cart, and convenient checkout without page reloads, which is critical for mobile screens within Telegram.
- Database: PostgreSQL / MySQL.

Implementation of your key requirements:
1. Universal integration with CRM: To allow you to easily change CRM in the future, I will implement the architectural pattern "Adapter" (decoupling). A universal data exchange interface will be created. When replacing the CRM system, there will be no need to rewrite the store code - just connect a new driver.
2. Integration with Nova Poshta: For instant city and branch selection in the app interface, data will be cached and pulled from your server's database (with auto-updating via cron), so the client does not wait for a response from Nova Poshta servers during checkout.
3. Transfer of rights: All code is developed cleanly, without using closed platforms. After the project is completed, you will receive full access to the repository (Git), database, and server.

Commercial terms:
- Estimated cost: 65,000 - 85,000 UAH (the exact cost will be fixed after agreeing on the final screen prototypes and selecting a specific CRM).
- Completion time: 25 - 35 working days (including full testing of integrations).
- Warranty: 6 months of free technical support (fixing hidden bugs, monitoring stability).

I am ready to discuss the details. Have a great day! Expand

Budget: 18000 UAH Deadline: 18 days

Hello! Developing Telegram Mini Apps (TMA) with complex backend integrations is my main specialization. I will create a full-fledged online store within Telegram that will operate smoothly like a native app.

Answers to your questions:

Technology stack:

Backend & API: Python (FastAPI) — will ensure maximum order processing speed and reliable integration performance.

Telegram Bot: aiogram 3.x — the most modern framework for Telegram.

Database: PostgreSQL — a reliable relational database for storing products, variations (color/model), and stock levels.

Infrastructure: Docker — the entire project will be packaged in containers. This will allow you to easily deploy it on any server.

Experience and Integrations (CRM + Nova Poshta):

I regularly work with REST APIs. To meet your requirement for versatility, I will use a modular architecture (Adapter pattern). The code for sending to the CRM will be placed in a separate module. If you decide to change the CRM, only one file will need to be rewritten, not the entire project.

I have extensive experience with the Nova Poshta API (extracting the list of cities/branches for the cart and creating shipping documents).

Admin mode:

Since there are not many products (~20), I suggest creating a convenient web admin panel or a secure admin panel directly within the bot (accessible only to your Telegram ID), where you can change stock levels, add photos, and edit prices with just a few clicks.

After the development is complete, I will provide you with all the source codes, the database, and a detailed launch instruction.

Timeline and cost:
I am ready to discuss the details of the frontend design (Mini App) in private messages to finalize the estimate. Approximately: from 14 to 18 days. Expand

Hello!

I am ready to take on the development of a Telegram Mini App for a store with a product catalog, shopping cart, order processing, admin panel, integration with CRM, and Nova Poshta.

I have commercial experience in backend development, integrations with external APIs, CRM/ERP systems, payment and logistics services. I also have experience working with Telegram bots, APIs, web applications, and building architecture that can be scaled and expanded without a complete overhaul of the project.

I initially see the implementation as follows:

Frontend:
Telegram Mini App on React / Next.js or React.

Backend:
Python, FastAPI or Django REST Framework.

Database:
PostgreSQL.

Integrations:
Telegram WebApp API, CRM through a separate integration layer, Nova Poshta API or transferring necessary data to CRM for further creation of shipping documents.

Administration:
a simple admin mode for managing products, prices, stock, models, and colors.

I would also think through the architecture so that in the future it would be possible to replace the CRM or add new features without a complete system redesign.

Estimated cost: 27,000 UAH depending on the specific CRM, the scope of the admin panel, and design requirements.

Estimated timeframe: 2–3 weeks after clarifying details, access, and final functionality.

Upon completion, I will provide the code, database, documentation for deployment, and all necessary access. I can also assist with deploying the project on the server.

I would be happy to discuss the details and offer an optimal implementation within your budget and for the further development of the project. Expand

Budget: 27000 UAH Deadline: 3 days

Good day!

For such a Mini App, it is advisable to divide the solution into a client part within Telegram, a backend API, an admin section, and a separate integration layer. This allows for not tying the business logic to a specific CRM and later changing it through an adapter rather than rewriting the core.

From a technical standpoint, the practical stack here is React/Next.js for the Mini App, FastAPI or Django REST for the backend, PostgreSQL for data, webhook integrations for CRM and Nova Poshta, and a separate secure admin panel. For such an MVP, it is important to immediately implement authorization through Telegram initData, control of stock levels, and an order log; otherwise, as the catalog grows, desynchronizations between the cart, CRM, and warehouse occur.

The key risk is the undefined CRM and the method of creating the shipping document. If the CRM creates the invoice itself, the integration is simpler; if the shipping document needs to be generated through the Nova Poshta API separately, the volume of work and testing increases. It is also better to move the admin panel to a separate web section rather than doing it within Telegram to avoid limiting the management of products, models, colors, and stock levels.

Approximately, such a project in a correct architecture starts from 35,000 UAH, with a timeline of 3–5 weeks depending on which CRM is used, whether there is documentation for the Nova Poshta API, and whether the shipping document needs to be created separately. If only a basic MVP without a universal layer for changing the CRM is needed, the estimate can be narrowed down after clarifying the integrations.

We have relevant experience with Telegram solutions, web APIs, and integrations with external services; for the Mini App, the principle is the same but with stricter requirements for frontend logic, sessions, and data synchronization. To provide an accurate estimate, three things are needed: which CRM you plan to connect now, whether the creation of the shipping document is needed in this project, and whether there are already ready products with photos and specifications, or if filling them in is also part of the scope.

I really liked your project. I have already created an online store using React, so I understand well how everything should work: products should be easy to find, add to the cart, and quickly check out, while you can conveniently manage everything.

For this, I propose to use React (Vite) for the Telegram Mini App, Node.js + Express for the backend, MongoDB for data storage, and the Telegram Web Apps SDK to ensure everything works correctly within Telegram.

I will make sure that the CRM connects separately, as a separate block. This means that in the future it can be easily changed without redesigning the entire project. Similarly, it will be possible to connect Nova Poshta or transfer all data directly to the CRM.

After completion, you will receive all the code, the database, and all access — everything will be with you.

This will take approximately 2–3 weeks. I will provide the exact cost after we discuss the details and the CRM that needs to be connected.

Good day!

Straight to the point, what you emphasized twice — it must be a Mini App, not a bot with buttons, and the CRM should be easily changeable without reworking. These are two different architectural solutions, and this is exactly what I would base the project on.

I am making the Mini App as a web application inside Telegram (React + Telegram WebApp SDK) with authorization through initData — that is, a native store in the Telegram window: catalog, product card with model/color/quantity selection, cart, checkout — everything inside, without menu buttons.

Regarding the "universal CRM" — the key is that orders do not go directly to a specific CRM. I keep a single order format inside, and a separate adapter delivers it. Changing the CRM in the future = replacing one adapter, not reworking the project. Exactly what you are asking about.

Nova Poshta: city and branch selection — through the NP API (search by branches), and creating the TTN either on our side through their API or we pass the data to the CRM if the CRM creates the TTN. This is one of the two things to agree on.

Stack: React + Telegram WebApp SDK (front), FastAPI + PostgreSQL (back), adapter layer for CRM, Nova Poshta API, Docker — so that the code, database, and access cleanly transition to you after delivery. Plus a simple admin mode (products/prices/stock/colors-models).

I have experience with Telegram applications and CRM/API integrations, so I know the pitfalls in advance — initData authorization, NP API limits, idempotency of orders (to avoid duplication on double taps).

Approximately 15–22 thousand UAH and 2–2.5 weeks — closer to the lower end if the CRM creates the TTN and the CRM is standard; a bit higher if the TTN and more complex logic are on us. I will provide the exact figure as soon as we clarify two points.

Two questions that determine the scope: which CRM exactly (KeyCRM, SalesDrive, something of your own)? And do we create the TTN or does the CRM? This is where we will start — write to me privately to discuss all the project details. Expand

Good day, Mykola!
I have understood the specifications. I am working on the Mini App (a store inside Telegram, not a bot with buttons) and CRM through a separate layer so that it can be changed without reworking.
Regarding the questions:

1. The cost is within 12,000, the exact name after you provide your CRM.
2. The timeline is about 7 days, in stages.
3. Stack: front-end on Telegram WebApp SDK + React, back-end on Python/FastAPI, database PostgreSQL, CRM through an adapter (initially KeyCRM), Nova Poshta via the official API, deployment on Railway/VPS.
4. Experience: I constantly work with Python bots and REST integrations. I am building the Mini App in the same stack and can show a demo catalog with a cart for your project in a couple of days.

I am ready to discuss. Vadim.

Good day, Mykola.

A catalog with 20 products inside Telegram is not difficult, but the real challenge here is to ensure the architecture survives the CRM change and the addition of new features without rewriting. Your store will operate as a full-fledged Mini App on React with the Telegram WebApp SDK: a catalog with photos, color variations, and models, a cart with the ability to change quantities, and an order form with city selection and Nova Poshta branch through API — the client does not enter the address manually but selects from a list, eliminating delivery errors.

Orders will automatically go into the CRM through an adapter layer: changing the CRM in the future comes down to replacing one module; the order logic remains untouched. The admin panel will give you full control over products, prices, stock, and variations without involving a developer.

The backend is on Go with PostgreSQL — fast, reliable, with a clean architecture that allows for new modules to be connected without reworking the core. The frontend on React will ensure smooth operation within Telegram.

All source codes, database, and accesses will be fully transferred to you upon completion. We will discuss the stack and details in private messages.

Options:

Basic
12,000–15,000 UAH
A minimally viable store for a quick sales start.

Hello! I am Volodymyr, a Full-Stack developer and founder of the engineering agency Vaysed. Your task regarding the development of a Telegram Mini App for an online store with CRM and Nova Poshta integration is completely clear to me. I specialize in creating full-fledged web applications within Telegram, rather than ordinary text bots, so I am ready to implement this project considering all scaling requirements.

For the implementation of the client side of the Mini App, I will use React.js, which will provide a smooth, fast, and intuitive interface for the catalog, color/model selection, and cart. The server side will be built on Node.js using a reliable PostgreSQL database. The backend architecture will be designed modularly — I will create a universal interaction layer (adapter) for order transmission. This means that if you decide to change the CRM system in the future, we will only need to update one small module instead of rewriting the entire store.

The selection of branches and cities for delivery will be implemented through the official Nova Poshta API, so customers will always see up-to-date information during checkout. The generation of shipping documents can be delegated directly to your CRM after the automatic transfer of all order data there. I will also develop a convenient, secure administrative panel through which you can manage a catalog of 20+ products with just a few clicks, change stock levels, prices, and add new variations.

I have extensive practical experience in creating similar solutions. In particular, I developed interfaces and logic for the Telegram Mini App WorkersTon, as well as configured complex multi-level integrations with databases and CRM within the PAYBACK CARTEL project. As stated in your requirements, after the development and final testing are completed, all source code, database, and access keys will belong to you one hundred percent.

The estimated development time for such a turnkey online store is from 8 to 14 working days. I will be able to provide the exact cost after I find out which CRM you plan to use. I also want to propose the following work format: to demonstrate my skills and your confidence in the result, we can create a basic trial test bot for free. You will be able to evaluate the logic and speed of work, after which we will proceed to the development of the full project.

I can create a store inside Telegram: catalog, cart, order processing, integration with CRM and Nova Poshta, simple admin panel. After project delivery — the code, database, and access will be completely yours.

How it works

The client opens the Mini App from Telegram (button in the bot or menu) → views the catalog → selects model/color/quantity → cart → checkout (name, phone, city, NP branch, payment, comment) → the order goes to CRM via API.

The administrator manages products, prices, stock, options (model/color) through a separate web interface.

Stack:

Mini App (front) React + Telegram Web App SDK
Backend Node.js (NestJS) or Python (FastAPI)
Database PostgreSQL
Admin panel Web panel in the same project
CRM Universal adapter (interface + implementation for your CRM; changing CRM — without rewriting everything)
Nova Poshta API: cities, branches; tracking numbers — via API or CRM (as agreed)
Hosting VPS ~$5–10/month

Functionality

Client: catalog (~20 products), photo/name/description/price, model and color selection, quantity, cart, checkout with all fields from the specifications.

CRM: automatic order transfer via API; architecture with the possibility to change CRM later.

Nova Poshta: selection of city and branch in the form; creation of tracking numbers — via NP API or through CRM.

Admin: adding/editing products, prices, stock, new models/colors.

Experience

Telegram Mini Apps — Web App SDK, authorization via Telegram, integration with the bot.
CRM — REST API, adapter pattern for different systems. Expand

Backend: ASP.NET Core Web API (.NET 8) — guarantees maximum speed, security, and the ability to handle high loads.

Frontend (Mini App): Responsive layout (HTML5, CSS3, JavaScript) using the official Telegram Web Apps SDK. The interface will perfectly adapt to any smartphones and the dark/light theme of Telegram.

Database: PostgreSQL or MS SQL Server for reliable storage of products, modifications (colors/models), and order history.

How your key requirements will be implemented:

Flexible integration with CRM: I will design the backend through interfaces (Strategy pattern). This will make the integration "isolated": if in the future you decide to change the CRM system, we will only need to rewrite one connector, while the logic of the Mini App and the database will remain untouched.

Nova Poshta: I will implement dynamic city and branch search through the official Nova Poshta API directly in the Mini App interface (the client selects a city from the list -> only the relevant branches of that city will be pulled). The data will be sent to your CRM for generating TTH.

Admin mode: We will create a secure closed section (accessible only for the Telegram IDs of administrators), where you can change prices, stock, add new colors or models of products directly from your phone in just a few clicks.

Security and access: All access, source code of the project, and database structure will be transferred to you upon completion. The project will be deployed on your server (for example, Ubuntu/Linux or Windows Server).

Terms and cost:

Estimated time: 14–21 days (including full testing of integrations and cart logic).

Project cost: 15000-18000 UAH

I am ready to discuss the structure of your CRM in more detail and start working. I look forward to collaborating! Expand

I can implement a Telegram Mini App store with a catalog of ~20 products, a simple admin panel for managing products, and universal integration with CRM and Nova Poshta. The estimated cost is 1100–2200 USD, with a timeline of 2–4 weeks depending on the details. I plan to use a stack of Node.js (Express) + PostgreSQL and a front end on Vue/React as a WebApp for Telegram, deployed on a VPS with HTTPS. I have practical experience in creating Mini Apps and integrations with CRM and the Nova Poshta API. Technical detail: a Mini App is a WebApp, requiring SSL and a bot for launch. Which CRM would you like to connect or should I create a universal integration?

Hello!

The task is clear — a Telegram Mini App store with a catalog, cart, order processing, admin panel, and integrations with CRM and Nova Poshta.

Stack: FastAPI + PostgreSQL on the backend, React on the frontend (Mini App), Telegram Bot API for launching the application. I will integrate the CRM through a universal adapter — so that in the future, the system can be changed without reworking the project. Nova Poshta — API for searching cities and branches when placing an order.

All code, database, and access will be completely yours after delivery.

Approximately 14+- working days. We will discuss the exact price and details privately — I want to clarify which CRM is planned and if there is already a design or style reference.

I hope for cooperation! Expand

Good day, according to the requirements, I would use pure Django, as it fully meets the described requirements.

I would be happy to discuss this project with you in more detail.

Budget: 15678 UAH Deadline: 1 day

Hello!

I am interested in your project. I have experience in developing Telegram bots, integrations with CRM, API of Nova Poshta, and building e-commerce systems. For such a project, I recommend the stack Laravel 12 + MySQL (Backend/API + admin panel) and React for the Telegram Mini App. This architecture will allow for easy scaling of the system, changing the CRM through a separate API adapter, and adding new functionality without reworking the entire system.

I preliminarily estimate the project at 80 to 120 hours depending on the volume of integrations and CRM functionality. The estimated implementation time is 3–5 weeks after the specifications are agreed upon.

I would like to clarify a few points:
* Which CRM do you plan to integrate? Is there a need to build a custom one?
* Is user authorization through Telegram (Telegram Login) and order history needed?
* Will payment be online (LiqPay, WayForPay, Monobank, etc.) or cash on delivery/payment upon receipt?
* Is it necessary to create shipping documents through the Nova Poshta API directly in the Mini App, or is it sufficient to pass the data to the CRM?
* Are promo codes, discounts, or a bonus system needed?
* Is there a ready design (Figma) for the Mini App and the admin panel?
* Are push notifications or messages in Telegram about the order status required?

After reviewing the details, I will be able to prepare a detailed estimate, break the project into stages, and propose an optimal architecture. Expand

A full-fledged store is needed inside Telegram with an admin panel, CRM, and Nova Poshta, where the client does not leave the messenger.

Stack: React (Vite) + Telegram WebApp SDK on the front end, Node.js + PostgreSQL on the back end. CRM integration through a separate adapter layer, so changing the CRM does not affect the rest of the code. I will connect the Nova Poshta API for searching branches during checkout. The admin panel as a separate protected page with JWT, without external services. Key risk: Telegram WebApp on iOS has limitations on viewport height and scrolling, with a workaround through CSS env(safe-area-inset).

Which CRM do you plan to use now: KeyCRM, Salesforce, your own, or is it still undecided?

Hello! I specialize in developing modern Telegram Mini Apps (TMA) and comprehensive e-commerce solutions. Your project perfectly aligns with my technology stack, which will make the store fast, convenient, and ready for scaling.

Here are detailed answers to your questions:

1. Technology stack:

Frontend (TMA): React / Next.js + Tailwind CSS. This will provide a smooth interface that feels like a native app within Telegram, with instant loading of products.

Backend, Database, and Admin Panel: Supabase (PostgreSQL). A powerful and modern solution. It will allow for easy management of the catalog, product variations, prices, and stock, as well as serve as a reliable base for your orders.

2. Experience and Integrations (CRM + Nova Poshta):
As part of my digital agency KenoStudio, as well as while developing my own e-commerce project Kiss of Aroma, I constantly work with complex cart logic, product variations, and checkouts.

Nova Poshta: At the order placement stage, I implement a convenient search for cities and branches through the official NP API.

CRM: I will set up a universal backend gateway. Order data will go into Supabase, from where it will be instantly transmitted to your current CRM via Webhook/API. If you change CRM in the future, you will only need to update one API key and endpoint.

3. Cost and Timeline:

Execution time: ~14–20 days (including the creation of the admin panel, integrations, and testing).

All source code, database, and access will be transferred to you 100% immediately after the release. The architecture will be built so that you can easily add new features without crutches and unnecessary rewrites.

Message me privately — I will send you examples of my work, and we will discuss the quick launch of your TMA in detail! Expand

Hello. I am ready to develop a full-fledged Telegram Mini App store for you with a catalog, shopping cart, order processing, integration with CRM and Nova Poshta, as well as a simple admin mode for managing products and prices.

Budget: 14900 UAH Deadline: 1 day

Hello!
I have about 3 years of experience in development. I have repeatedly connected websites and bots with Nova Poshta and various CRM systems, so there are no hidden pitfalls for me here.

What exactly I will do and how it will work:
Convenient store: I will create a modern showcase directly in Telegram, where the client can choose the color, product model, add everything to the cart, and place an order with just a few clicks.

Smart integration with CRM: I will ensure that all orders instantly fly into your CRM. I will write the code "with a margin" — if in six months you decide to change CRM to another, it can be done very quickly and without rewriting the entire store from scratch.

Nova Poshta: I will set up data transfer (city, branch) to the CRM so that waybills are created automatically with one click, or I will integrate directly into the application.

Simple admin panel: I will create a convenient admin mode directly in Telegram (accessible only to you), where you can change the price, add a new color, or edit stock in a minute.

Regarding money and deadlines:
Deadlines: approximately 1.2-2.5 weeks (turnkey work including testing).

Cost: I am aiming for a budget of $400 – $600.

🤝 Regarding the budget: I fully understand that financial frameworks can vary. I am ready to listen to your proposals and adjust to your budget. If necessary, we can start with the essentials (catalog + cart + CRM), and add the admin panel or additional features a bit later to fit into a comfortable amount for you.

Write to me - I will consult for free on the project. Expand

There is an almost ready solution. Details can be discussed in private messages.

Budget: 15000 UAH Deadline: 14 days

Mykola, I see you need a full-fledged store within Telegram so that customers can conveniently browse products and place orders, while you can effectively manage this process through integration with CRM and Nova Poshta. This will significantly simplify order processing and improve the customer experience.

I will develop a Telegram Mini App with a detailed catalog, a functional cart, and an intuitive order form. All data will be automatically transmitted to your CRM via a universal API, allowing for easy creation of shipping documents through Nova Poshta or directly in the CRM. Additionally, there will be a simple admin panel for quick management of products and their stock.

Are there already specific preferences for the CRM system you plan to integrate with?

Budget: 27000 UAH Deadline: 24 days

We already have a practically ready similar solution for a store in the Telegram Mini App, which can be quickly adapted and launched for your catalog, CRM, and Nova Poshta ))

I estimate the full working MVP starting from 65,000 UAH and about 24 days.
Stack - React for Mini App, Node.js or NestJS for the server part, PostgreSQL for the database, Telegram WebApp API, integration with CRM through a separate API layer, so that later it would be possible to replace the CRM without a complete overhaul.
Look, here’s the nuance - 15,000 UAH is rather enough for the first technical prototype or a very trimmed start, not for a full store with an admin panel, inventory, orders, and integrations.

For implementation, I would go like this - first the catalog, cart, and order placement, then the admin panel for products, prices, colors, models, and inventory, then the transfer of orders to the CRM, and only after that Nova Poshta - either through API or through CRM if it creates the TTN itself.
We will make the architecture modular, so we can add payment, discounts, analytics, repeat sales, or an AI assistant for processing orders without restructuring the project.
Well, yes, it’s better to lay a solid foundation once than to heroically repair what should have been a system =)

Please clarify 2 points.
- Which CRM is being used or is still being chosen.
- Is payment needed only as a method selection, or should online payment be connected.
