Moving from 1С/BAS to Creatio

Move the sales side from 1С/BAS to Creatio in stages: clients, contacts and open orders go across while the team keeps selling

Companies that have outgrown keeping sales in 1С/BAS often look at Creatio, a CRM where outside services can be connected without programming. 1С/BAS is on the official prohibited software list, which makes the decision easier. We move the sales side in stages: we look at what is really in 1С/BAS, clean out duplicates, make a trial load and let both systems run side by side until the figures match. Creatio is a CRM, so accounting and tax reporting go to a separate accounting program your accountant chooses. Below: what we carry over, how the move goes and which Creatio capabilities we rely on.

What we move

1С/BAS → CreatioCounterparties from 1С/BAS — companies and individuals with tax code and addresses — become client records in Creatio, in the structure your administrator has set up; duplicates are merged before the load.
1С/BAS → CreatioContact people with phones and emails become contacts linked to their company, so the manager knows whom to call.
1С/BAS → CreatioCustomer orders that are not yet closed become open sales in Creatio, so they are finished there rather than in 1С/BAS.
1С/BAS → CreatioPayments on those open orders move with them as information, so the manager sees what the client has already paid.
1С/BAS → CreatioSales history by client for the period you choose is carried over as reference, so the manager sees what the client bought before.

How the move goes

First your administrator creates a separate Creatio user for the load: every outside request to Creatio must sign in, and the exchange goes through a fixed address on your own Creatio domain.
We look at what is really in your 1С/BAS: which catalogues and documents sales use, what is outdated; together we decide what moves to Creatio and what stays in the archive or goes to the accounting program.
Before the move we clean the data: merge duplicate counterparties, fix phones and names, and mark old records the CRM does not need.
We make a trial load of a small part of the data, and your managers check clients and open orders on familiar examples before the full load.
For the transition both systems run in parallel: new sales go into Creatio, and 1С/BAS stays at hand as a reference, so the team keeps selling.
We reconcile clients and open orders in Creatio against 1С/BAS on the same date; every difference is explained before the next step.
Only after that is the sales side of 1С/BAS switched off; the accounting part stays until your accountant moves to their new program, and the old database is kept as an archive.

Automation scenarios

One client, several cards

Before the same client sits in 1С/BAS under several spellings, and managers argue whose client it is.

After duplicates are merged before the move, and in Creatio the client has one card with the whole history.

Managers wait for the operator

Before to see what a client bought or which of his orders are still open, a manager asks the person who works in 1С/BAS.

After the client, his open sales and his history are in Creatio, and the manager sees them himself.

Sales and accounting part ways

Before everyone thinks leaving 1С/BAS means the accountant loses their tool.

After sales work in Creatio, and the accountant moves the books to the program they chose, without waiting for the sales side.

How it works technically

For those who want to check: each point links to the official documentation page it comes from.

BAS products are on Ukraine's official list of prohibited software (Cabinet resolution №1335 of 22.10.2025, based on Presidential Decree №601/2024 of 02.09.2024). The direct ban applies to the state sector, critical infrastructure and systems processing state information resources.

According to the same documentation, the platform automatically builds a REST interface using the OData protocol, through which outside systems can read, change, create and delete data over HTTP.

All external requests to Creatio must be authenticated; the vendor recommends cookie-based Forms authentication through the AuthService.svc web service.

External REST services can be connected without code through a low-code constructor: Creatio itself generates and sends the request, receives the response, and creates or updates records or triggers business logic.

Limits

The limits come from both systems. Creatio's open documentation does not give an exact daily number of requests: it depends on your specific instance, so we check it with you before the start and load long history in portions. The Creatio documentation we rely on does not describe a ready import of a 1С/BAS database, so the data is exported from 1С/BAS through its open exchange interface, prepared and loaded step by step. Creatio is a CRM: accounting and tax reporting from 1С/BAS do not move into it and need a separate accounting program chosen with your accountant. 1С/BAS is on the official prohibited software list: we do not take projects for state bodies, critical infrastructure or systems with state data, and with private businesses we discuss the risk openly.

Questions

Is it legal to stay on 1С/BAS?

1С/BAS is on the official prohibited software list. The direct ban covers the state sector, critical infrastructure and systems with state data. For a private business it is formally allowed but considered a risk — check with your lawyer.

Will sales stop during the move?

No. For the transition both systems run in parallel: new sales go into Creatio, and 1С/BAS stays as a reference until the reconciliation shows the same figures.

What about accounting?

Creatio does not keep the books. Sales move to the CRM, and accounting and tax reporting move to a separate accounting program that your accountant chooses; we agree the boundary at the audit.

Can the 1С/BAS database simply be imported into Creatio?

The Creatio documentation we rely on does not describe such an import. We export the data from 1С/BAS through its open exchange interface, clean it and load it step by step, checking each part with your people.
