Integrations with Ukrainian services
Your website, store, CRM or internal system connected to the services Ukrainian businesses run on: delivery, payments, banks, software cash registers, electronic documents and signatures, marketplaces and public procurement, so data moves between them without being retyped.
What we connect
Delivery
Nova Poshta, Ukrposhta and Meest: branches and parcel lockers, delivery costs, waybills created from an order, tracking and returns, through each carrier’s API.
Payments and banks
LiqPay, WayForPay and monobank acquiring for card payments, and the business APIs of PrivatBank and monobank for statements and payment status in your accounting.
Software cash registers
Fiscal receipts from Checkbox or another software cash register, issued automatically when a payment arrives and sent to the customer by email or in a messenger.
Electronic documents and signatures
Contracts, acts and invoices exchanged through Vchasno or Paperless, and documents signed with a qualified electronic signature from your own system.
Marketplaces and CRMs
Products, prices, stock and orders synchronised with Prom.ua, Rozetka and Horoshop, and orders flowing into KeyCRM or SalesDrive.
Public procurement
Tenders from the Prozorro public API filtered by your codes and regions and delivered to your team, so nobody checks the portal by hand every morning.
Hire integration developers
Dedicated integration developers
Integration developers who join your team full time, work in your tools and process, and report to your lead. You interview them; we carry the Ukrainian contract, payroll, invoicing and leave.
Integration development projects
A defined piece of integration development with a scope, a fixed plan and a named lead on our side who owns the result and reports progress in your channels.
Ongoing integration development
Integration development as a continuing service: the same people every month, a backlog you prioritise, and hours you can see in our portal and on the invoice.
The dedicated team page explains how specialists join your team, and the outsourcing page covers project delivery, take-overs and how we charge.
Who works on your integration development
Back-end engineers
.NET, Python or Node.js services that call each API
Business analysts
Which data goes where, and who owns it
QA engineers
Test payments, test waybills and failure cases checked end to end
How we build an integration
We start from the process: what happens to an order, a payment or a document from the moment it appears until it is closed, and which system holds the truth at each step. The integration follows that map, and every exchange is logged, so a lost payment or waybill can be traced in minutes.
Keys and certificates live in your secret store rather than in the code, each service gets only the access it needs, and a failed call is retried or raised to a person instead of disappearing.

Questions about integrations with Ukrainian services
Our platform already has a module for Nova Poshta or LiqPay. Why build anything?
If a ready module covers your process, we install and configure it. We write an integration when the module does not fit, for example when orders also go to a CRM, receipts must follow the payment, or several systems need the same data.
How much does an integration cost?
It depends on the number of services, the data that moves between them and how failures are handled. After a short brief you get a written estimate with the scope, the dates and the price, and the work starts only when you have agreed to it.
Can you work with a system another team built?
Yes. It starts with a read-only review of the code and the current integrations, then a written plan of what to change, before anything touches production.
How quickly can integration developers start?
When the right integration developer is available, the start is gated only by your interview and the NDA and IP assignment. Otherwise we run a search, which typically produces candidate profiles within two to three weeks, and nobody starts until you have said yes.
How do we hire integration developers through BigTree108?
Tell us the work, the seniority and the hours you need. We propose one or two people with their profiles, you interview them the way you would interview your own hire, and you sign one agreement with BIG TREE 108 LLC and receive one invoice a month.
Who owns the work they produce?
You do. Every specialist has a signed contract with BigTree108 that assigns all work product to the company, and our agreement with you assigns it onward. Code, designs and documents are delivered into your own repositories and tools, not kept where only we can change them.
Tired of retyping orders and payments?
Tell us which systems you use and where data is copied by hand. You get an answer within one business day: what to connect, how, and an estimate.
