Syrve/iiko + LiqPay: QR menu, table orders, tips, confirmation by the waiter

Budget: 27000 UAH Deadline: 7 days

For the first stage, I would approach technical design within 5-7 working days. The cost of this stage is 30,000 UAH. After that, there will be an exact integration scheme, MVP assessment, and a list of risks regarding Syrve/iiko, LiqPay, and individual entrepreneurs (FOPs).

We have experience with POS integrations, payments, personal accounts, admin panels, and complex order logic. The approach with Resto.Front.Api or Syrve POS API should be chosen after checking your version of Syrve/iiko, the license, the waiters' working scenario, and where exactly the open order at the table needs to be managed.

I envision the architecture as follows - a QR page for the table, an order server, a waiter or administrator panel, a synchronization module with Syrve/iiko, a payment module LiqPay, an event log, and a separate layer of rules for FOPs. Orders from QR do not go to the kitchen automatically - they enter a confirmation queue, the waiter checks the items, and only then does the system create or update the order in Syrve/iiko.

A separate plugin will most likely be needed if reliable operation with the open table, local front of Syrve/iiko, waiter confirmation, and future automatic closing is required. If your configuration allows everything to be done through the available API without a local plugin - we won't complicate it.

Tips of 5%, 10%, 15%, a custom amount, or skipping them should be implemented as a separate step before payment. Here’s the nuance - tips cannot simply be mixed with kitchen items, as this leads to accounting poetry, which rarely has a happy ending =/ It is necessary to determine how exactly the restaurant handles tips legally and technically.

!!Critical point - several FOPs and fiscalization!! Alcohol and kitchen must follow different rules, categories, payments, or invoices. For the MVP, I would not implement automatic check closure, but give the administrator a reliable payment status, breakdown by FOPs, and safe manual closure. Full automation should only be done after tests on a real fiscal scheme.

Estimated timeline - MVP approximately 4-6 weeks. The benchmark for MVP is 220,000-380,000 UAH. The full version with automatic closure, stable fiscalization, error log, roles, and proper monitoring is approximately 450,000-900,000 UAH, depending on the API, plugin, and cash logic requirements.

Two things need clarification.
> What version of Syrve/iiko do you currently have and is there access to Resto.Front.Api or Syrve POS API?
> How are FOPs, PrivatBank/LiqPay merchants, and fiscal checks for alcohol and kitchen currently divided?

Hello! Great and detailed project brief. I have experience with Syrve (iiko) architecture, C#, and LiqPay integrations.

The bottlenecks in your project are the correct split of payments across different individual entrepreneurs (to avoid issues with fiscalization) and intercepting the receipt before it is automatically printed in the kitchen. I have a clear vision of how to implement this flow reliably and know how to avoid developing a heavy cash register plugin at the MVP stage to significantly save your budget.

Message me privately — I will briefly outline the optimal integration scheme for your restaurant and provide guidance on the numbers!

Budget: 12000 UAH Deadline: 14 days

Good day! I was working on a web order for a restaurant with LiqPay payment — QR on the table, menu, cart, bill. Regarding Syrve, the main question is: do you have access to the iikoCloud/Syrve API (cloud token), or is the cash register only local (RMS on-site)? This affects how the order will be placed on the table and whether items can be added to an already opened check. The rest — confirmation by the waiter before the kitchen, tips 5/10/15/your own amount, payment via LiqPay — is done smoothly. I am ready to take this on, approximately 12-14 days. We will discuss the details.

Budget: 27000 UAH Deadline: 14 days

Hello! 👋

Your project is well described, and it is clear that you have already thought through the main business logic. I have experience in developing complex backend systems, integrations with external APIs, payment services, CRM/POS solutions, and designing scalable architecture. I also have experience with Iiko Syrve API.
My main stack:

Backend

- Python
- Django
- Django REST Framework
- FastAPI
- PostgreSQL
- Redis / Celery

Frontend

- React
- Next.js
- TypeScript

Integrations

- REST API
- LiqPay / payment integrations
- Telegram notifications
- Webhooks
- Docker / Nginx / VPS

How I see the MVP architecture:

* The QR code uniquely identifies the table.
* The frontend displays the current menu retrieved via the API.
* Orders go to the own backend with the status "waiting for confirmation."
* The administrator or waiter confirms the order.
* After confirmation, the backend sends the order to Syrve/iiko.
* If there is already an open order for the table, new items are added to it; otherwise, a new order is created.
* Payment is processed through LiqPay using a webhook to confirm the status.
* The admin panel displays the statuses of orders and payments in real-time.

For tips, I would implement a separate step before payment with options:

* 5%;
* 10%;
* 15%;
* custom amount;
* no tips.

The issue with multiple individual entrepreneurs needs to be resolved at the business logic and fiscalization level. The final decision depends on the capabilities of your specific Syrve/iiko configuration and the method of integration, so this should be determined during technical design.

Answers to your questions:

Have you worked with Syrve/iiko? I have worked with integration APIs and POS solutions, but before starting implementation, I would conduct a technical audit of the capabilities of your specific Syrve/iiko configuration.

Resto.Front.Api / Syrve POS API - yes, I have implemented solutions for a restaurant chain.

LiqPay / PrivatBank? Yes, I have experience integrating payment services via API and webhook.
Do you need a separate plugin? It depends on the chosen method of integration. After the audit, we can determine whether the Syrve API is sufficient or if it is more appropriate to use the Resto.Front plugin.

Order confirmation by the waiter - a separate queue of QR orders in the web panel or on the administrator's tablet with "Confirm" / "Reject" buttons.

Tips - a separate step before payment with the amount passed along with the payment transaction.

I look forward to your message in private!
Best regards, Andriy! Expand

Good day!

I have reviewed your task. I propose to implement a modern web solution based on the Syrve Cloud API (REST API) instead of the outdated approach with local plugins in C#. This architecture is used by top services (Choice, Expirenza). It will make the system independent of the hardware in the restaurant, more stable, and save your budget.

Answers to your questions:

Do you have experience / Have you worked with APIs? I specialize in web development and integrations via REST API. Instead of the local Resto.Front.Api (which requires C#), I will integrate the system through the cloud Syrve Cloud API. This is a modern standard that works with JSON and does not require writing workarounds in C#.

Is a separate plugin needed for Syrve? No, a plugin is NOT needed. The system will communicate directly with the cash register through the official Syrve cloud.

Have you done integrations with LiqPay? Yes, I have experience working with payment gateways.

How do you envision the architecture? The guest scans the QR ➔ enters the web application (frontend) ➔ collects the cart ➔ my backend processes the order and sends a request to the Syrve Cloud API ➔ the administrator sees the order at the cash register ➔ after payment, the status is updated via webhooks.

How to implement confirmation (so it doesn't go directly to the kitchen)? Orders from the QR menu are sent to Syrve as "External Orders" (delivery/on the table). At the cash terminal in the restaurant, it flashes as new. The administrator checks it, clicks "Accept," and only after that does the printing of tickets to the kitchen occur.

How to address the issue with multiple individual entrepreneurs (FOPs)? This is resolved at the level of my backend. Products are divided by categories (Kitchen / Alcohol). Two different merchants are registered in LiqPay. Upon payment, the backend splits the cart into two parts, and the guest makes two transactions (or we set up payment splitting if allowed by the bank's terms). Fiscalization is perfectly clean.

How to implement tips? Before proceeding to payment, the guest sees a screen with buttons (5%, 10%, 15%, custom amount, skip). To avoid confusing tips with the income of the FOP, it is ideal to set up the transfer of these funds to separate LiqPay/Mono wallets of the waiters.

Timeline and cost:

MVP (QR, menu, cart, sending orders to Syrve with manual confirmation at the cash register, without auto-payment) — approximately 2-3 weeks.

Full version (LiqPay, 2 FOPs, tips, statuses) — an additional 3-4 weeks.

I will be able to provide an exact budget after agreeing on the details and flow.

I am ready to conduct a short technical consultation and explain in more detail why a cloud REST architecture is the best choice for this task. I look forward to collaborating! Expand

Budget: 27000 UAH Deadline: 35 days

We have a practically ready foundation for such a QR-order with an admin panel, which can be quickly adapted for Syrve/iiko, LiqPay, and the rules of your individual entrepreneurs (FOPs). We can discuss it here; I’m available in the chat =)

We have worked with Syrve/iiko and similar POS systems. I would choose between Resto.Front.Api or Syrve POS API after checking your license, access, and where open table orders are actually available.
We have worked with LiqPay and PrivatBank - payment, callback, signature verification, payment statuses, manual reconciliation for the administrator.

I see the architecture like this - a QR page for the table, a backend with a cart and statuses, a waiter screen for confirmation, an integration layer with Syrve/iiko, a payment layer with LiqPay, and an administrator action log.
A plugin for Syrve will likely be needed if you need to reliably see open tables and add items to the current order through Resto.Front.Api.
If Syrve POS API is sufficient, part of it can be done without a local plugin, but this needs to be checked on your installation.

I would handle the waiter confirmation as a queue of QR orders - accept, decline, change comment or item, and only after that send it to Syrve/iiko.
Tips of 5%, 10%, 15%, a custom amount, or skip are done on the screen before payment, and then they need to be processed correctly as a separate amount or service item depending on the fiscal scheme.

Look, there’s a nuance here...
It’s better to handle several FOPs through product groups, payment routing rules, separate merchants or LiqPay accounts, and separate fiscalization logic.
At the first stage, I would leave manual receipt closure by the administrator, as this reduces the risk of errors with alcohol and the kitchen.

MVP is approximately 4-6 weeks and 180,000-260,000 UAH.
The full version with automatic closure, roles, analytics, and stable fiscal logic - about 8-12 weeks and 400,000-700,000 UAH.
Technical design before development - 3-5 days, which will provide an exact API, plugin, and fiscalization scheme.

Questions before the exact estimate:
What version of Syrve/iiko is installed and is there access to the API?
Should alcohol and kitchen items be paid for with one payment for the guest, or are two payments acceptable under the hood?

Good day, Serhii!

Having reviewed the feedback from other specialists, I would like to assist you with the project. Below are examples of successful cases:

- Traffic growth of 689% in 3 months.
- Traffic increase of 486% for a printing company.
- Traffic growth of 4854% in 15 months.

For now, I will refrain from making an offer as I need to better understand the goals of the integration. To propose the optimal collaboration option, please clarify:

- What are the launch timelines? Is a quick MVP launch planned?
- Is there a detailed technical specification or vision for the integration?
- How do you envision the architecture of the solution? Is a separate plugin needed for Syrve?
- How will the QR order confirmation be implemented by the waiter?
- How to address the issue with multiple individual entrepreneurs in fiscalization?

The cost and timelines for development are influenced by:

1. The need for technical consultation.
2. A clear vision of the architecture and the need for a plugin for Syrve.
3. The complexity of integration with LiqPay or PrivatBank.
4. The number of features: QR order confirmation, tip settings.
5. Time for implementing the MVP and the full version.

At the beginning of our collaboration, it is important to agree on the final vision of the integration, which we will reflect in the technical specification. I prefer to form a vision based on competitor analysis and your wishes.

I have experience working with Syrve/iiko and LiqPay, understand the specifics of the restaurant business, and the importance of integration for improving service. I know how to set up the system for guest convenience and optimize staff operations.

The next step is to discuss the project and understand how well we fit together. Let's fix the details in correspondence or in a meeting to better understand your needs and find the optimal approach to integration. Expand

I have over 3.5 years of experience in developing fullstack web applications, stack: TypeScript, Vue/Nuxt, NestJS, PostgreSQL. I understand the tasks: integration of QR menu from the table, synchronization of orders via Syrve/iiko API, confirmation by the waiter, and payment through LiqPay.

I can assist with technical consulting at the first stage: determining how to connect to the Syrve/iiko API, which plugin is needed, proposing an architecture for the correct operation of two individual entrepreneurs and fiscalization, assessing the MVP and timelines. I have experience building similar integrations in B2B products where transaction accuracy and reliability are crucial.

I am ready to discuss the details of your project and offer a clear technical solution.

Good day!

I have reviewed the technical description. I can assist with the design and implementation of the QR menu integration with Syrve/iiko, setting up the order logic from tables, integrating payment systems, and processing order statuses.

At the first stage, I suggest conducting a technical analysis of the Syrve/iiko API, determining the optimal architecture of the solution, and assessing the feasibility of implementing an MVP without unnecessary complexity for the restaurant staff.

I work with REST APIs, payment system integrations, and web solutions for automating business processes.

I am ready to discuss the details and propose a step-by-step implementation plan.

Hello!

We can help with the automation of Playerok, but from the description, it seems to be quite a large system, not just a simple bot. There is a dashboard, Autocode, Job, Autobump, Relist, statistics, a Telegram panel, Google Sheets, and a separate Roblox/Swizzyer workflow.

We specialize in automating business processes, internal panels, Telegram bots, parsing, dashboard systems, and integrations with external services. We have a good understanding of tasks involving statuses, queues, logs, manual control, and protection against erroneous duplicates.

For a budget of 4000 UAH, I can offer the first stage:

- analyze the current scenario;
- check the technical limitations of Playerok / Swizzyer;
- design the structure of the modules;
- create a prototype of one basic scenario or Telegram panel.

It is better to evaluate the full functionality separately after checking access and the method of automation. This will be safer and more realistic in terms of deadlines. Expand

Hello! I did the integration with LiqPay — I will close the payment part and QR, I am ready to figure out the Syrve API together with you at the start. I hope for cooperation!

Answers to:

1. Experience with Syrve/iiko — I haven't worked directly, but I am ready to study the API at the start.
2. Resto.Front.Api / Syrve POS API — I will review the documentation before starting.
3. LiqPay / PrivatBank — yes, I have integration experience.
4. Architecture — QR → web page of the table → cart → waiter confirms → Syrve API → LiqPay payment → status to the administrator.
5. Plugin for Syrve — depends on the version, we will determine during the consultation.
6. Waiter confirmation — a separate admin panel or Telegram bot with a confirmation button.
7. Tips — I will implement as a separate step before payment with buttons 5/10/15% + custom amount + skip.
8. Two individual entrepreneurs — two separate LiqPay accounts, distribution of items by categories at the cart level.
9. MVP — approximately 3-4 weeks.
10. MVP cost — we will discuss after the consultation, currently there are no examples of similar work. Expand

Budget: 1500 UAH Deadline: 1 day

Good day. I am ready to engage in the first stage (technical consultation and architectural assessment), but honestly, I cannot commit to the full development of the MVP: it requires C# and Resto.Front.Api, which I do not have. If a consulting scope is of interest to you, I propose the following.

Regarding the architecture, the solution is typically divided into four layers: the guest part (QR page with menu, cart, tips, payment) on Next.js or any SSR framework plus backend on Python or Node with REST API, an integration layer with Syrve or iiko through the official Cloud API (documented and accessible without a C# plugin for most scenarios including creating and modifying orders by table), a payment layer through LiqPay with server-side validation via signature, and an admin panel for the waiter to confirm QR orders. Multi-tenant by individual entrepreneurs is done at the routing level of items by categories in the payment layer, not in the POS.

On important issues from your terms of reference: Syrve has a cloud-based API (api-ru.syrve.live) where orders can be sent without a plugin. The C# plugin is only needed if you need to change the behavior of the POS terminal from within. Confirming QR orders by the waiter is easiest to do with a separate admin page with a websocket to the backend plus a push to the POS after confirmation. Tips of 5-10-15% typically go as a separate item on the check with a service charge type or through the LiqPay payee_split API.

What I can do in the first stage: a complete architecture document with API selection, integration scheme, MVP estimation in hours, answers to all questions from your terms of reference, and a recommendation for a C# developer for the actual implementation, with whom you can continue. In terms of time, 1 working day for a detailed consultation after familiarizing myself with your current state of the POS and individual entrepreneurs. If this format does not suit you, I completely understand.

Budget: 10000 UAH Deadline: 5 days

Good day. We have 4 years of experience in web development and business system integrations. For such a solution, we envision an architecture through a separate web service QR-menu integrated with Syrve/iiko via Syrve API or Resto.Front.Api, where orders first go to the admin panel for confirmation, and only after that is the order created or supplemented in the POS system. Payment and tips can be implemented through LiqPay with options of 5%, 10%, 15%, or a custom amount, and for working with multiple individual entrepreneurs, we will propose a separate scheme for distributing items and fiscalization according to business requirements. We can assist with both technical consulting and MVP design, as well as full implementation of the solution. Examples of our work: apple-family.com.ua/uk, 3magency.co.

Budget: 18000 UAH Deadline: 21 days

Hello,

The task is non-trivial — especially regarding multi-entrepreneur and order confirmation by the waiter. Let's go through the points.

Architecture

Three layers:

Frontend (React SPA) — QR → table page with menu, cart, tips screen, check
Backend (Node.js / Python) — middleware between the front, Syrve, and LiqPay; this is where the confirmation queue lives
Syrve receives orders only after confirmation, via iiko Cloud API
Confirmation scheme: the guest sends the order → it goes to the backend with a pending status → the waiter/admin sees it in a simple web interface or Telegram bot → confirms → the backend checks if there is an open order at the table via order_by_id, and either adds items to the existing one (order_add_items) or creates a new one (order_create).

Is a plugin for Syrve needed?

No. iiko Cloud API (REST) covers everything: get the menu, create/add to an order, close the check. Resto.Front.Api is for in-POS plugins in C# that run inside the POS itself. It is not needed for this task.

Tips

LiqPay does not have a native field for tips — and that’s fine. Implementation: the guest selects 5/10/15% or enters an amount, the backend calculates the total (check + tips) and sends one amount to LiqPay. Tips are recorded in the database separately — for reporting.

Two entrepreneurs — fiscalization

LiqPay supports split payment: one payment is automatically divided among several merchant accounts. Scheme: the backend divides items into two carts when forming the payment — alcohol (Entrepreneur 1) and everything else (Entrepreneur 2), calculates amounts, and passes split parameters to LiqPay. Both entrepreneurs receive funds within one transaction. To do this, the split function needs to be enabled at the merchant account level — a request to LiqPay support.

Syrve can see one order — the question of whether to split into two checks by entrepreneurs is resolved together with the accountant and the configuration of the fiscal registrar. At the first stage, the admin closes the check manually — this resolves the bottleneck.

Terms and cost

I am ready to conduct a short technical consultation — write to me privately.

MVP — QR menu, cart with comments, confirmation by the waiter, sending to Syrve, basic payment via LiqPay, statuses for the admin: 18,000–22,000 UAH, 2–3 weeks.

Full version — tips, split payment between entrepreneurs, auto-closing of the check, admin dashboard with payment history: an additional 15,000–20,000 UAH, another 2–3 weeks. Expand

I have worked with the iiko API and LiqPay, so I understand the task from the inside. Essentially, this is a connection: the front end on the table (QR -> menu -> order), the backend that writes the order to iiko via the API and keeps the status, plus LiqPay for payment and optionally tips as a separate transaction. The key point here, in my opinion, is the confirmation by the waiter: we need to understand whether this is through the iiko cashier interface or a separate mobile notification. I am ready to discuss the details and estimate the scope of work.

Budget: 1000 UAH Deadline: 7 days

I understood the task. In the past, I often visited familiar restaurateurs and know how painful it is to correct mistakes in accounting and receipts later, so it's better to think through the architecture before starting development. I see the sense in starting with a technical consultation and integration scheme to understand whether the Syrve API will be sufficient or if a separate plugin will be needed for your processes. After that, we can quite accurately assess the MVP, timelines, and budget. Please let me know which version of Syrve is currently used in the restaurant? Is there already a ready QR menu, or does it also need to be developed? And how is the work with several individual entrepreneurs organized in the POS system?
