An online store and 1С/BAS live separately
Before a manager copies every order from the store into 1С/BAS by hand at the end of the day.
After the order lands in 1С/BAS on its own as soon as it is placed.
Accounting & ERPUA1С/BAS integration & automation
Already running your accounting in 1С/BAS? We automate the work around it
Many Ukrainian companies keep their books, stock and sales in 1С/BAS and don't plan to switch overnight. We connect 1С/BAS to everything else you run — CRM, online store, payments, document exchange — so orders, customers and documents move between systems on their own instead of being copied by hand. And if you are planning a move off 1С/BAS, we help carry the data over without stopping the business.
What we connect
- New orders from your CRM or online store appear in 1С/BAS on their own, with the customer and items already filled in.
- Stock levels from 1С/BAS flow back to the store and CRM, so managers don't sell what is no longer in the warehouse.
- Customer cards stay the same in every system: a change made in one place shows up in the others.
- Invoices and acts prepared in 1С/BAS go out for electronic signing without being retyped.
- Payments received online are matched to the right order in 1С/BAS, instead of someone checking the bank statement line by line.
- If you decide to move off 1С/BAS, we export customers, products and history and load them into the new system.

After the data is carried over in stages while work continues as usual.
How it works technically
For those who want to check: each point links to the official documentation page it comes from.
BAS is a line of accounting and ERP programs, from small business (BAS Малий бізнес, BAS Бухгалтерія) to the corporate market (BAS ERP, BAS Управління холдингом) and industry solutions such as agriculture and construction.

Limits
1С/BAS is on Ukraine's official list of prohibited software: for state bodies, critical infrastructure and systems with state data its use is banned, so we don't take such projects. Private businesses are not directly covered, but lawyers call it a risk — we'll say honestly when migration makes more sense. Numeric limits for the OData interface are not quoted in the open documentation.
