Hello. I have extensive experience with OpenCart. I am ready to implement integration with Checkbox.

Budget: 5555 UAH Deadline: 3 days

Hello! I see the task "Set up the PRRO for the online store" regarding the online store / OpenCart. I have practical experience in refining stores: modules, checkout, payments/shipping, import/export, theme adjustments, and speed optimization. First, I will quickly check the current implementation, agree on the details, and make adjustments carefully, without unnecessary risk to the working site.

Budget: 12000 UAH Deadline: 5 days

I offer PRRO Checkbox - you already have an account, a trading point, and a cash register, and in the api.net.ua instructions, there is ready logic for receipts, project-receipts, and linking the TTN to the cash on delivery receipt.

Cost - 12,000 UAH. Deadline - 5 working days. This estimate is for the option where we work through the existing CRM api.net.ua and OpenCart 2.3.x, setting up payment scenarios, checking LiqPay, cash on delivery from NP, and manual transfer to FOP. If it turns out that a separate OpenCart module is needed without relying on the ready integration of api.net.ua - the budget will be higher.

Access to the OpenCart admin panel, Checkbox account, api.net.ua, and test LiqPay is required. Additionally, it is desirable to have 2-3 real examples of orders for each type of payment to avoid creating beautiful but flawed fiscal magic =/

> Questions
>> For LiqPay, should the receipt be created automatically after successful payment, or after manual confirmation by the manager?
>> For cash on delivery from NP, should a project-receipt be made before issuance and an active receipt after payment, as described in the api.net.ua instructions?

Similar in logic to working with e-commerce, accounting, and integrations

Hello! 👋

My partner and I, as designers, have already set up fiscalization for stores on OpenCart, so the topic of receipts and PRRO is well known to us — we know which payments need to be processed and which do not.

We suggest working specifically through Checkbox✅ — you already have an account with a point of sale and cash register, so there's no point in dragging something else in. This is the most stable option, and the documentation at api.net.ua is tailored for it.

What we will do: we will connect the cash register via API, set up the opening/closing of shifts, and outline the logic for your payments 👇

🔸 LiqPay — we will automatically process the receipt immediately after payment
🔸 Transfer to FOP — you are right here, fiscalization is not needed
🔸 Cash on delivery — we will agree on the timing of the receipt according to your accounting policy

Next, we will connect everything with the CRM according to their instructions and test it on real scenarios to ensure receipts are correctly recorded in the account.

Price/term: 13k UAH • 4–6 working days

Fiscalization is a field where a mistake = fines, so we take responsibility for it. Micromanagement is not needed; you simply receive the finished result 🚀

Write to us — we will clarify a couple of points regarding cash on delivery and get started! Expand

Hello! I saw the task — PRRO for an online store on OpenCart, and I immediately understood the essence: you need the receipts to be processed automatically without unnecessary actions on your part.

I specifically propose Checkbox as PRRO — it has a decent API, works reliably with OpenCart, and meets all the requirements of the State Tax Service. The logic is as follows:
the receipt is automatically generated when the order status changes
linking with the tracking number of Nova Poshta if needed
fiscalization of online payments (LiqPay, Wayforpay, etc.)
returns/cancellations are also processed correctly

⚙️ I will do it through a module/extension for your version of OpenCart — not Modbыcz and nothing external. I will link it to the checkout and order_history events so that the cash register operates automatically without manual intervention.

Why not "manually through the cabinet": I have already encountered this case in stores — automation through API eliminates the manual "process receipt" and fully addresses the compliance issue for the 30-day control of the State Tax Service. One store, after such a connection, processed ~1200 receipts/month without errors for a month.

✅ I am currently free, have no other projects — I can start today. If you already have a Checkbox cabinet open — let me know, and I will draft a step-by-step plan in 10 minutes: which Order → Receipt events to link and what to check in the cash register settings. Expand

The task is clear - connecting PRRO Checkbox to OpenCart 2.3.x via CRM api.net.ua. I reviewed the integration instructions - fiscalization is implemented through the Checkbox API directly in the CRM without unnecessary OpenCart modules. I will set up fiscalization for all three types: LiqPay (receipt at "Paid" status), IBAN (excluded from fiscalization), Nova Poshta (receipt at "Delivered" status). I will test it on a test product for 1 UAH before the full launch.

Good day! I have done the integration of the PRRO with OpenCart for fiscalization for online stores.

The checkbox is suitable - there is ready documentation and the cabinet is already set up, which simplifies the work. We are fiscalizing LiqPay (online payment) and cash on delivery via NP. The transfer to the FOP account indeed does not require fiscalization.

Feel free to contact!

Good day. We are a web studio https://corecode.com.ua

We can implement this task, we provide guarantees. Write to discuss.

Hello! The task is completely clear. I work with the OpenCart 2.3 platform and know the specifics of connecting the PRRO in Ukraine very well.

Since you are using CRM (api.net.ua) and it already has a ready native integration with Checkbox (as per your link), I suggest implementing the fiscalization at the CRM level. This is much more reliable than overloading OpenCart with modules and will allow your managers to see all receipts directly in the order cards.

I will fully configure the system for your 3 types of payments:
1. Online via LiqPay - I will set up automatic creation and closure of the receipt in Checkbox immediately after the successful change of the order status to "Paid".
2. Invoice for individual entrepreneurs (IBAN) - we will exclude this type of payment from automatic fiscalization, as payment by details does not require issuing a receipt through the PRRO.
3. Cash on delivery (Nova Poshta) - we will set up the logic so that the receipt is generated automatically at the right moment (for example, when the order status in CRM changes to "Delivered/Received" based on Nova Poshta tracking data).

What is included in the work:
- Setting up the Checkbox cabinet (cash register, key) and its connection with api.net.ua according to the instructions.
- Mapping (synchronization) of order statuses between OpenCart 2.3 and CRM, so that payments from LiqPay correctly trigger the necessary event.
- Testing the sending of receipts on a test product (priced at 1 UAH) to check the display of nomenclature, VAT/tax groups, and transmission to the State Tax Service.

Cost of work: 3,000 UAH (clearly within your budget, as we are using ready-made system modules without developing from scratch).
Deadline: 1-2 days.

I am ready to start working today. To begin, I will need access to the OpenCart admin panel and the CRM cabinet. I look forward to hearing from you in private messages! Expand

Hello, Alexander!
You are looking for a specialist to set up the PRRO for your online store. This means ensuring the correct processing and issuance of information about products, prices, and orders. For this, I will pay attention to the details of the system configuration so that it works according to your needs. I have already worked on a similar project, so I can immediately see where there will be nuances with setting parameters and integrating with other services of the store.
I will confirm the price and timeline once I clarify the details of the task.

Hello, Alexander, I see that you need to set up the PRRO Checkbox for OpenCart 2.3.x to automatically fiscalize payments from LiqPay and cash on delivery, using the already prepared cabinet.

I will perform a complete integration of Checkbox, which will ensure the correct sending of order and payment data. This will allow you to comply with the legal requirements for fiscalization without distracting from your main work.

To more accurately assess the scope, I am interested in whether you plan to integrate Checkbox directly through the OpenCart module or will you be using the API.net.ua link for data exchange?

Budget: 6000 UAH Deadline: 3 days

We already have a practically ready similar solution for an online store with PRRO, so I suggest Checkbox and quick adaptation for OpenCart 2.3.x =)

Price - 6000 UAH.
Deadline - 3 working days, if there is no need to rewrite the OpenCart payment module.

In your api.net.ua instructions, there is a scenario for a project-check for cash on delivery, so Checkbox is the least risky option here.
For Likpay, we will fiscalize after payment confirmation, for cash on delivery from Nova Poshta - after the payment status or via project-check, transfers to the FOP account can be left without fiscalization after confirmation with the accountant.

After access is provided, we will connect to OpenCart, check the test cash register of Checkbox, process Likpay payments, create checks, send them to the client, and log errors.

Question - should the check be created in OpenCart or in your simple CRM via api.net.ua?
Question - for cash on delivery from Nova Poshta, is the check needed at the moment of creating the TTN, after receiving the funds, or as a project-check?
