Development of a CRM for processing orders from Prom, Rozetka, and own websites

Budget: 27000 UAH Deadline: 90 days

Good day. I can help with the development of a CRM tailored to your requirements, including integrations with Prom, Rozetka, your own websites, 1C, carriers, and Checkbox. Please let me know:
1. Is there already a ready technical specification, database schema, or interface prototypes, or do they also need to be developed?
2. Which version of 1C is being used and how is the integration available (API, web services, file exchange, etc.)?
3. Which carriers need to be integrated (Nova Poshta, Ukrposhta, Meest, etc.)?
4. What platforms are your own websites built on (OpenCart, WooCommerce, Shopify, custom CMS, etc.) and do they have an API for order exchange?
5. Is a full deployment of the CRM on your server needed with subsequent support and system development?

Zhuan, I see the task as a single control center for order management: from Prom, Rozetka, websites, and manual channels in one interface. I can design a CRM with a separate internal status, two-way synchronization, flexible integrations with 1C, carriers, and Checkbox, as well as admin settings for keys without the involvement of a programmer. I have experience with API integrations, logging, and complex workflows — I am ready to discuss the architecture and stages.

Budget: 27000 UAH Deadline: 25 days

Hello! I create exactly such CRMs for e-commerce: order collection from Prom, Rozetka, and websites via API, my own internal status, integration with 1C, TTN, and Checkbox. I will move the management of integration keys to the admin panel, with logs for each source. Two-way synchronization of statuses is only possible where the marketplace provides it via API, so I need to clarify: for which sources is it critical?

Budget: 27000 UAH Deadline: 45 days

Hello. The task is clear: a single manager's workspace is needed, where orders from Prom, Rozetka, websites, and manual entries are collected into one registry, and the entire cycle (internal status, 1C, TTN, Checkbox receipt) is closed in one interface, without accessing cabinets. There are a few points that should be discussed right away, as they determine the architecture. The internal CRM status is separate from the marketplace status - this is correct. Two-way synchronization is not equally possible everywhere: Prom and Rozetka allow reading orders and updating some fields via API, but their set of statuses is limited, so we map your internal statuses to those allowed by their API, not the other way around. Integrations (1C, carrier, Checkbox, API keys) will be brought to the admin panel as separate modules with on/off switches for each source, so you can manage without a programmer. Regarding logistics and receipts: creating TTN with the carrier, saving the number, and returning it back to Prom and Rozetka, while the receipt in Checkbox acts as a project receipt with fiscalization control upon payment, so that unpaid ones are not processed. I work with Checkbox and Nova Poshta in my practice with stores, so these nodes are familiar. To provide an exact timeline and break it down into stages, please let me know: which carrier is primary (Nova Poshta?), what version of 1C you have, and how you plan to provide access to the APIs of Prom and Rozetka. I would start with an MVP - a single registry plus manual orders plus one end-to-end channel, then we connect the rest. Regarding the budget, I will proceed step by step within yours, and I will provide exact figures after agreeing on the list of integrations.

Hello! Jumping between the Prom, Rozetka, Checkbox, and 1C offices is chaos that slows down managers' work and leads to lost orders.

I run the KenoStudio agency. We specialize in developing powerful custom systems and complex API integrations based on modern technologies (Next.js, Supabase). I will design a single lightning-fast CRM for you with a clean interface (Swiss minimalism), where the entire cycle—from two-way synchronization of statuses to generating shipping documents and fiscalization—will take place in one window.

You will receive a fully manageable system with logging of every action and convenient API key management without the need to dive into the code.

The project is architecturally scalable. I suggest a 10-minute call to discuss the database logic, security, and development stages.

Good day! I studied your technical specification for the CRM.

Most of the required functionality is already available in ready-made Ukrainian CRMs, such as KeyCRM or SalesDrive. Developing from scratch will be significantly more expensive and will require constant support, as the APIs of marketplaces change regularly.

Have you considered ready-made solutions? If so, what exactly did not satisfy you about them? Perhaps it would be more optimal to use a ready-made CRM and only refine a specific module, for example, for selective export to 1C.

Hello, we are currently developing a CRM platform for an American freight carrier with the same architecture as in your specifications (a single order registry from various sources, integration with accounting — QuickBooks Online, automatic creation of shipping documents, a complete action log, key management from the admin panel). I have a question: what is your 1C configuration (BAS / UT 3.0 / Retail) and have any of these integrations (Prom / Rozetka / Checkbox / carrier) already been implemented, or are we starting everything from scratch? I suggest we get in touch; I will provide a free consultation on the architecture and we can outline a development plan in stages + I will tell you about my team!

Hello.

I am a NodeJS developer. I have experience in developing CRM systems. Write to me, and we will discuss.

Budget: 27000 UAH Deadline: 1 day

Hello! I carefully read the specifications - the task is clear.

I have experience with a similar stack.
I immediately see the key nodes - bidirectional synchronization of statuses (webhook + polling), a separate field for the source status parallel to the internal CRM status, a reference for payment method correspondence for Checkbox, and secure storage of keys on the backend with logging. I will lay all this out correctly from the very start.

I work on Laravel + React, with a settings section where the administrator manages the keys and auto-export to 1C for each source separately.

I honestly note that the scope here is larger than the specified budget.
I suggest we discuss in more detail to talk everything over more accurately.

Hello. I have experience in developing CRM systems on Next.js/Nest.js. I am ready to collaborate.

Budget: 27000 UAH Deadline: 14 days

Hello! Very well-structured technical specification, the entire business logic is immediately clear. The main pain point is understood: it is necessary to ensure that the manager can process orders from start to finish in a single interface, without the need to access the Prom, Rozetka, carrier, or Checkbox dashboards. The project is extensive but technically clear. Here’s how I will organize the work: I will consolidate all channels (two Prom stores, Rozetka, two websites, and manual sales) into a single order registry while preserving information about the source. I will set up parallel status operations: the internal CRM status will operate independently, but thanks to two-way synchronization, statuses on the marketplaces will be updated automatically. Integration with 1C will be flexible: through settings, you will be able to selectively enable or disable automatic uploads for each individual source. For integration with Checkbox, I will implement a payment method compliance directory so that the system correctly generates receipt projects. The generation of shipping documents will occur within the card, and for orders from Prom and Rozetka, the number will be automatically transmitted to the marketplace. Manual orders (phone, messengers) will be treated as a separate source with its own creation mechanics but will go through the same processing cycle (1C, shipping documents, receipt). We will securely address security issues: all API keys will be managed by the administrator through the interface without programmer intervention, and each action will be logged in the journal. I have a couple of technical clarifications to start: What specific configuration of 1C (or BAS) are you using, and is there a ready API/HTTP service on its side for receiving orders? Which carriers are we integrating at the first stage (only Nova Poshta, or is Ukrposhta also needed)? Write to me privately, we will discuss the details, select the optimal stack for the backend, and I will provide guidance on exact timelines and budget.

The budget of 27,000 UAH for such a CRM, in my estimation, does not even cover normal integration design. A realistic first stage is from 180,000 UAH and from 45 working days if we go through MVP with the core CRM, Prom, Rozetka, 1C, TTH, Checkbox, and the integration log.

Here, an important nuance is that I would not stitch everything chaotically through one-off scripts. A separate order architecture is needed - internal CRM status, external source statuses, synchronization queues, retries, error logs, administrator rights, and an API key settings page. Otherwise, the system seems to work, and then managers catch discrepancies between CRM, 1C, and marketplaces =/

> Please clarify which specific 1C is being used - UTP, UNF, BAS, or another configuration
> Which carriers are needed in the first stage - Nova Poshta, Ukrposhta, Meest, or several at once

We can keep the start simple - first, we do a brief technical design, describe the modules, integrations, synchronization scenarios, and after that, we provide an accurate step-by-step estimate. A penny-wise person pays twice - in CRM, it seems, this is especially quickly verified in practice. Expand

We will design and implement a centralized CRM system (integration bus) for aggregating orders from Prom, Rozetka, and our own websites. We will build a fault-tolerant architecture based on Python (FastAPI/Node.js) and PostgreSQL with flexible logging of each step of API integrations, task queues (Celery/RabbitMQ) for processing webhooks, and an isolated access key management module.

Hello! I am Nina, the manager of the IT agency Valflow. Valentin, our Senior Engineer, specializes in designing complex accounting systems, integrating heterogeneous APIs (ERP, CRM, marketplaces, logistics services), and optimizing databases. We clearly understand how to build the architecture so that status synchronization works correctly in both directions without loops and failures.

Our technical approach to system implementation:
— Unified registry & Status model: We will create a flexible database structure in PostgreSQL, where each order has a system status in CRM and custom mappings for Prom/Rozetka statuses. The processing of incoming orders and status changes will be moved to asynchronous queues to ensure the manager's interface works instantly.
— Logistics module and pRRO: Integration with the API of Nova Poshta / Ukrposhta for generating TTH on the fly and automatically pushing tracking numbers back to the marketplaces. Connecting Checkbox for fiscalizing receipts based on payment method compliance.
— Logging and Management: All API keys are encrypted in the database and managed through the admin panel. Each request to external services is accompanied by detailed logging (Request/Response timestamps) so that the administrator can see the reason for the error (for example, invalid token or 500 response from the marketplace).

Proposal for development stages (Sprints):
Creating a full-fledged aggregator with bidirectional synchronization of marketplaces, logistics, Checkbox, and 1C is a large-scale infrastructure project. The budget specified in the title (27,000 UAH) covers the first basic stage (MVP):

— Sprint 1 (Core and Order Aggregation): Designing the database architecture, creating the manager interface, implementing custom manual order addition, and basic order reception from Prom/Rozetka via Webhooks/API. Key management module.
Cost: 27,000 UAH | Term: 10–12 days.

Subsequent sprints (Connecting Nova Poshta, Checkbox, and custom integration with 1C) will be calculated separately after analyzing your 1C configuration. We work exclusively through the Business-Safe platform.

Hello. I will create a CRM for orders from Prom/Rozetka/websites: a single queue, statuses, clients, products, synchronization, and roles. We will start with the MVP and one channel, then connect the rest. The price is negotiable.

Budget: 27000 UAH Deadline: 32 days

Hello!

This is a comprehensive CRM system with a large number of integrations, so it is important to immediately lay down a scalable architecture and the ability to seamlessly connect new sales channels and services.

For implementation, I propose a modern stack:
Frontend: React / Next.js + TypeScript;
Backend: NestJS (Node.js);
Database: PostgreSQL;
Queues and background tasks: Redis + BullMQ;
Deployment: Docker.

Within the CRM, the following can be implemented:
* a unified order registry from Prom, Rozetka, own websites, and manual channels;
* an independent system of internal statuses with two-way synchronization where the API supports it;
* integration with 1C with flexible export rule settings for each source;
* integration with carriers for automatic creation of shipping documents and transfer of numbers to marketplaces;
* integration with Checkbox for automatic creation of receipt projects and control of their fiscalization;
* manual order creation with a full cycle of subsequent processing;
* an administrative module for managing API keys, integration settings, and synchronization rules;
* a user action log and logging of all integrations for quick search and error analysis.

The architecture will be built modularly so that in the future it will be easy to add new marketplaces, delivery services, CRM, ERP, or payment systems without reworking the core logic.

Preliminary estimate:
MVP development time: 4–8 weeks.
Cost: from 4,000 USD (exact estimate after reviewing the full technical specification and list of integrations).

I am ready to work in stages with a demonstration of results after the completion of each stage. I would be happy to review the detailed technical specification and propose an optimal technical solution. Expand

Budget: 27000 UAH Deadline: 21 days

Good day!
I can implement a CRM system that will consolidate all orders from Prom, Rozetka, personal websites, and manual channels into one interface. The manager will be able to fully process orders without the need to switch to the marketplaces, carriers, or other services.

For such a project, I recommend custom development on Laravel + React. This stack allows for building a flexible architecture without the limitations of ready-made CRMs, easily integrating Prom, Rozetka, 1C, Checkbox, delivery services, and other services, as well as scaling the system in the future without issues. All integrations, API keys, synchronization rules, and settings can be moved to an administrative panel to manage them without the developer's involvement.

I will pay special attention to logging all integrations, user action logs, a flexible role and access rights system, as well as stable two-way synchronization of statuses between the CRM and external services.

I am ready to show similar projects and discuss the system architecture in private messages. For an accurate estimate, I would like to familiarize myself with the complete technical specifications, the list of integrations, and understand which processes are planned for the first MVP.

I would be happy to discuss the details!

I understood the task - a single CRM is needed that collects orders from Prom, Rozetka, own websites, and manual applications in one place, with a separate internal status and synchronization where possible. I will create a single order register with a clear source for each and flexible toggling of export to 1C for each channel separately. I will set up integration with carriers so that the shipping document is created automatically and the number is immediately pulled back into Prom and Rozetka. I will separately connect Checkbox for receipts with fiscalization control and maintaining compliance with payment methods. I have experience with similar multichannel integrations and am ready to discuss the prioritization of sources and the order of connection.

Hello! The technical specification has been studied in detail. The task is completely clear, the logic of parallel statuses, selective 1C, and mapping for Checkbox is fully calculated. I will implement this ERP/CRM "single window" system on a reliable stack: Laravel + Filament PHP + PostgreSQL + Redis.

Architectural implementation of each of your requirements:
1. Multichannel and Statuses (p.1, 3.1): Strategy pattern for sources. In the database, the order will have two isolated fields: "internal_status" and "source_status". Synchronization in both directions is isolated in Redis queues, so the manager's interface never hangs.
2. Flexible 1C and Security (p.2, 3.2, 5): A checkbox "is_1c_auto_export" is created in the sources table for the admin. All API keys are encrypted at the database level (Eloquent Encrypted Casts), and each action and HTTP request is logged in the audit log (Spatie Activitylog).
3. TTN and Checks (p.3.3, 3.4, 4a): TTN generation automatically triggers a background push of the number to Prom/Rozetka. For Checkbox, I will develop a UI reference guide for mapping external payment methods to Checkbox types, ensuring 100% correct fiscalization.
4. Manual input "5+1" (additional item): A separate service class without external synchronizations, generating an internal ID and interactive product search from the nomenclature through Filament Select/Search.

Step-by-step development plan (sprints with demos):
- Sprint 1 (Register, Manual Orders, Source Integration + parallel statuses): 50,000 UAH | 15-18 days.
- Sprint 2 (1C Module with toggles + Carrier TTNs + push tracking numbers): 45,000 UAH | 12-15 days.
- Sprint 3 (Checkbox with mapping + Key Encryption + Action Logging): 40,000 UAH | 10-12 days.
Total: 135,000 UAH.

Good day.

I really want to take on this project because it’s not just about “creating a CRM,” but about gathering all order processing into one proper system without chaos between Prom, Rozetka, websites, 1C, carriers, and Checkbox.

I see the solution as a single center for the manager: orders from all channels go into the CRM, have their source, internal status, action history, synchronization with marketplaces, transfer to 1C, creation of shipping documents, and project receipts.

We can create a convenient order card, access roles, flexible API key settings through the admin panel, integration logging, a queue of problematic orders, statistics by sources and managers, as well as prompts for the next actions for the manager.

I am genuinely interested in creating a non-template CRM, but a tool that will save the team time every day. I am ready to dive into your process, propose architecture, development stages, and a reasonable estimate for timelines and budget.

Hello! I would be happy to develop a fast and user-friendly CRM for you in Python / JavaScript with a clean and understandable interface.
Here’s how I envision the implementation:
We will create a convenient separation by statuses (New, In Process, Paid, Shipped, Return, etc.) so that the manager can drag and drop cards with one click and see the whole picture.
Automatic deduction of stock when creating an order and notifications if any item is running low. No confusion with availability.
We will integrate the API of Nova Poshta (and Ukrposhta if needed) so that tracking numbers are created directly from the order card, and delivery statuses automatically update the order status in the CRM.
Managers will only see what they are supposed to (their orders, processing), while you, as the admin, will see complete analytics, margins, net profit, and employee performance.
I write clean, modular code that can be easily scaled in the future (for example, connecting new marketplaces, Telegram bots, or telephony). I will deliver the project turnkey, help deploy it on the server, and show you how to work with all of this.

Let’s chat. When would it be convenient for you to discuss?

Budget: 27000 UAH Deadline: 30 days

I have studied your technical task in detail.

The level of business logic writing (separation of CRM statuses/sources, key encryption on the backend, and mapping payment methods for Checkbox) is exemplary.

I propose to implement the backend of the system in Python (FastAPI) and the frontend in React or Vue. The stack based on FastAPI is ideal for this project for several reasons:

Powerful integration with APIs and parsing: Python has the best ecosystem for working with third-party services and data parsing. If it is necessary to "on-the-fly" pull content that is not available in the API or parse specific pages, this can be implemented very quickly.

Asynchronous and speed: FastAPI operates in asynchronous mode, which is critical for simultaneous processing of requests from 5+ external sources (Prom, Rozetka, websites, 1C, Checkbox, Nova Poshta).

Data reliability: Thanks to the Pydantic library, the system will strictly validate each JSON package from marketplaces, which will eliminate errors due to sudden changes in their API.

API key security: I will apply AES-256-GCM encryption at the database level using the Python cryptography library.

Queues and fault tolerance: For processing orders and synchronizing statuses, we will set up task queues (Celery / Arq + Redis).

Checkbox automation: For orders with the payment type "cash on delivery," the project check will be created upon generating the TTN, and it will be automatically fiscalized at the moment when the carrier changes the TTN status to "Received/Picked Up."

Product catalog for manual orders: From where the CRM should pull nomenclature, prices, and product stocks (import from a file, synchronization with 1C, or parsing/synchronization from one specific donor site).

Integration with 1C: Which version of 1C/BAS are you using, and do you have a 1C specialist who will set up the HTTP service (endpoints) on their side to receive JSON packages from the CRM?

I am ready to break the project into 4-5 clear stages (Milestones) with a demonstration of results after each stage. Let's discuss the details!

About 2 months of intensive work.

We will divide the project into 5 stages. The payment for the first stage (base and security) is only $1000. You pay for the next step only after you see and test the results of the previous one.

Total budget: $5,000 – $7,000 (depending on the complexity of their API and the readiness of 1C). Expand

Hello!

I can develop a separate CRM for you, where the manager can actually manage all orders in one place, without constant switching between Prom, Rozetka, websites, 1C, carriers, and Checkbox. Such systems require not just an admin panel, but a well-thought-out logic of synchronization, statuses, integrations, and action logs, so that everything works stably in daily operations.

We work with Laravel + Vue and have experience in developing business systems and automating processes, so we can implement a CRM with scalability in mind, flexible settings for the administrator, and proper support after launch. Please write to me in private messages on the platform, and we will discuss the architecture, implementation, service costs, rates, and deadlines in more detail.

Why do you need a separate CRM?
I can implement everything connected at once in 1C.
I have extensive experience.
I provide a guarantee for the completed work.

Hello.

I can take on the CRM development in stages. I would start with a technical map of integrations and a working scenario for one order source, to properly lay out the architecture of statuses, logs, retries, and external APIs from the beginning.

Then, this logic can be scaled to other sources, 1C, carriers, Checkbox, and manual orders without chaos. After reviewing the access and API documentation, I will be able to confirm the estimate.

Good day.
I have already written such a CRM, but without 1C. Adding 1C is not a problem.

I have reviewed your detailed technical assignment. The project is architecturally well-structured. I specialize in developing complex accounting systems, API integrations, and databases on the .NET (C#) / PostgreSQL platform, so I am ready to implement a stable and secure turnkey CRM system for you.

Since the system is to become a single workspace for managers without the need to switch between offices, I propose the following technical solutions:

Source Architecture (Prom, Rozetka, Websites): The system is built on interfaces (Strategy pattern). Each source is an isolated module. This will allow connecting any number of new stores or websites through the admin panel by simply specifying the API key. Reverse synchronization of statuses (webhooks/workers) will operate in parallel with the internal logic of the CRM.

Flexible integration with 1C and pRRO Checkbox: The logic of selective auto-export of orders by flag will be implemented at the level of backend business rules. A dynamic mapping directory of payment methods will be created for Checkbox to ensure error-free fiscalization due to data type mismatches from marketplaces.

Security and Logging: According to point 5 of your technical assignment, all API keys will be stored in encrypted form in the database. The frontend (browser) will not have access to them — all requests will strictly go through a secure C# backend. A complete audit log will be implemented (who among the managers changed the status, when the TTN was sent to Prom, what error came from Rozetka).

Manual Orders: A module for creating orders with intelligent search for products and clients from the internal database will be developed, which will operate under the same lifecycle but isolated from external marketplaces.

Technology Stack:

Backend: ASP.NET Core 8 / .NET 9 (C#) — an industry standard for financial and ERP systems.

Database: PostgreSQL (ideal for logging and registries).

Frontend: SPA application (Vue.js or Blazor) for instant interface response without page reloads by the manager.

Cost and Terms:
The cost indicated in your announcement (27,000 UAH) covers the development of only 1-2 basic modules from such a number of integrations (Prom, Rozetka, 1C, Nova Poshta, Checkbox, Websites, manual input). To create a reliable business-level system with complete logging and flexible key management:

Real term: 45-60 days (phased delivery in sprints: core + DB > marketplaces > 1C/Checkbox > testing).

Cost: starting from 95,000 UAH (ready to discuss the final figure after agreeing on the order of connecting sources). Expand

Good day!

Interesting project. I understand that it is necessary to create a CRM for centralized processing of orders from various sales channels, including Prom and Rozetka. I work with Laravel and have good experience in developing similar systems.

I have done integrations with various APIs, particularly for automating order processing and synchronizing statuses. I know how to set up interaction with 1C so that administrators can conveniently manage all settings. It is important that everything is intuitive, and I will help implement API key management through the CRM interface.

I also have experience with logging actions and controlling integrations, which is critically important for the stable operation of the system. Flexible automation settings and support for manual orders are what will enhance the efficiency of business processes.

I hope to help implement your project quickly and efficiently.

Добрий день!
Уважно прочитав ТЗ
Помітив деталь: ви правильно зробили що винесли окремо довідник відповідності способів оплати для Checkbox — це не дрібниця, це саме те місце де у більшості подібних систем потім виникають проблеми з фіскалізацією. Реалізую це як повноцінний адмін-розділ з маппінгом для кожного джерела окремо.
Також бачу що ручні замовлення (телефон/Viber/Telegram) повинні проходити той самий повний цикл що й маркетплейсні — без зворотної синхронізації статусів, але з повним 1С + ТТН + Checkbox. Це окрема механіка яку треба закласти в архітектуру одразу, не докручувати потім.
Стек: React + Node.js + PostgreSQL + Docker.

I can build a CRM where the manager fully processes orders from Prom, Rozetka, websites, and manual channels in one interface, with separate internal statuses and two-way synchronization where the marketplace APIs allow it. I will provide flexible on/off unloading to 1C for each source, automatic creation of TTH for carriers with number transfer, integration with Checkbox for fiscalization, and an admin panel for managing API keys. I will ensure logging, idempotency of requests, and a detailed event log. Do you have API keys and technical documentation available for Prom and Rozetka?

Budget: 27000 UAH Deadline: 24 days

We have almost a ready foundation for a similar CRM for orders from marketplaces, which can be quickly adapted for Prom, Rozetka, websites, 1C, carriers, and Checkbox. We can start with a working MVP - a single order register, internal statuses, basic integrations, logging, and a settings panel. The budget for the full system is 27,000 UAH, which seems too low - here, only the integration layer and event log would require a separate phase.

I want to clarify two points to avoid guessing:
- Which specific 1C is being used and is there already a ready exchange via API, XML, or files?
- Which carriers are needed in the first phase - Nova Poshta, Ukrposhta, Justin, or others?

For implementation, I would go through a separate core for orders - we bring all channels to a single model, then separately manage CRM statuses, external synchronization, creation of TTN, projects of checks, and unloading into 1C. The administrator will be able to manage keys, source rules, payment compliance with Checkbox, and enable or disable automatic unloading without a programmer. All actions of managers and responses from integrations are logged to see where exactly the order got stuck or why the document was not created.

Relevant examples:

- https://business.ingello.com/forma-bpm - Automation of internal workflows, statuses, and responsibilities

Main page for Freelancehunt - https://systems-fl.ingello.com/ua

At the first stage, access to test accounts for Prom, Rozetka, the website, Checkbox, 1C, or a description of the current exchange method is needed. If API access is not ready yet, we can start with designing the data schema and prototyping the interface to quickly agree on the order processing logic. I am available, and we can discuss the details here and choose a phase that can be launched without unnecessary bureaucracy. Expand

Zhuan Moslem, I see that you need a single control point for all orders, so you no longer have to switch between Prom, Rozetka, and your own websites. This will allow you to centralize processing and forget about the routine of tracking statuses and shipping documents.

We will create a custom CRM with a centralized database that will automatically collect orders from all sources. We will set up two-way status synchronization, integrate with 1C for data export, connect carriers for shipping documents, and Checkbox for fiscalization. There will also be the option to manually create orders. The result will be complete automation of routine operations and clear control over each order.

To plan the integration more accurately, please let me know which specific 1C modules you are currently using for sales accounting?

Budget: 27000 UAH Deadline: 14 days

The task is to create a single window for the manager, where orders from Prom, Rozetka, own websites, and phone calls are processed completely, without switching between dashboards.

I would build it on Laravel + Vue: a separate worker for each channel synchronizes orders via webhook or polling, normalizes them into a single model with its own CRM status. Two-way synchronization of statuses — through a queue (Redis + Horizon) with idempotent tasks, so that restarting does not duplicate actions. An admin panel for API keys, payment mapping for Checkbox, unloading rules to 1C — without the involvement of a programmer. Integration with Nova Poshta / Ukrposhta for tracking numbers and reverse transmission of the number to the marketplace. A complete event log linked to the order and source.

The key risk is that the Rozetka API has limits on polling and does not always support webhooks, so I would implement a buffer queue with retry logic.

What carriers are needed, and is there already ready documentation from the 1C developer regarding the unloading format?
