Hello! I am Volodymyr, the founder of the engineering agency Vaysed.
Your issue with setting up fiscalization for the Opencart platform in conjunction with the CRM DNTraid and the payment gateway WayForPay is a classic integration task that our team regularly solves. The complexity often lies in the lack of direct seamless communication between the acquiring module, the accounting system, and the chosen PRRO, such as Checkbox or Vchasno.Kasa. To address this issue, we will not interfere with the core of your online store, but will deploy a reliable server layer based on Python or Node.js. This microservice will instantly intercept the signal of a successful transaction from WayForPay through the webhook system, synchronize data with DNTraid, and automatically send the correct API request to your PRRO for registering the fiscal receipt for the individual entrepreneur. After generation, the receipt will be automatically sent to the client, and the order status in the CRM will be updated without any manual intervention.
Our agency has deep practical experience in creating such fail-safe solutions for e-commerce. We have successfully set up complex two-way synchronization between online stores, payment systems, and external CRMs in the Prudbay Clothes Support ecosystem. We implemented reliable processing of background processes and webhooks without data loss under high loads in the Lumos system architecture, and we refined strict order routing logic in the large-scale project RESTART 2026.
You can evaluate our engineering approach and learn more about the implemented infrastructure solutions on the agency's official website: https://vaysed.me/.
Message me privately so we can determine which software cash register service you plan to use, and we will promptly set up this automation turnkey.

Hello! I have studied your task. The problem is clear: it is necessary to connect OpenCart, CRM DNTrade, and WayForPay so that receipts are automatically registered in the PRRO for FOP during online payments. Since there is no ready-made module, I will set up the integration via API. An accountant is not needed here — this is purely a technical task of synchronizing services (Checkbox / Vchysno).
**My experience for your project:**
I specialize in developing online stores on OpenCart and regularly set up integrations with payment gateways and CRM systems. I clearly understand the technical side of data transmission via API and the operation of webhooks, so I will implement a stable issuance of receipts without errors and failures.
**First step:**
I will look at the current settings of the connection between OpenCart and DNTrade and the documentation of your PRRO to determine which side is technically simpler and more correct to implement the data sending for fiscalization.

We already have a practically ready similar solution for payments, receipts, and integration with CRM, and we can quickly adapt it for OpenCart, DNTraid, and WayForPay and discuss it here on the marketplace now - I'm available ))

Regarding the cost, I would estimate 2500 UAH for the first technical stage - checking the scheme, configuring the ready modules, and a test fiscal receipt.

If it turns out that a separate integration through the API is needed, we will provide a separate estimate after checking the access.

Essentially, we need to link payment, order status, CRM, and the fiscalization service so that the receipt is created automatically and without manual confusion.

Please clarify:
… - which PRRO or fiscalization service you want to use
- whether orders are currently being transferred from OpenCart to DNTraid automatically or manually

We can keep it simple if there is a ready module for your PRRO.

As a small bonus, we can prepare a simple automatic error check in orders so that fiscalization doesn't break due to minor issues (:
