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

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?

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.

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

!!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

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!

Hello!

I am pleased to develop for you a modern, fast, and scalable Telegram Mini App store with full integration. I have solid experience in developing business logic for inventory management systems, orders, and API architecture based on the .NET platform (C#).

The technology stack I propose for the project:

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

Budget: 27000 UAH Deadline: 14 days

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.

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)?

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

Budget: 15000 UAH Deadline: 14 days

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?

Budget: 15000 UAH Deadline: 14 days

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.

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.

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.

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: 2 days

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.
