1C and BAS migration
Move accounting data from 1C and BAS
We migrate accounting history, balances and essential customisations into your chosen platform with parallel operation and controlled reconciliation.
Discuss your project →Why Ukrainian organisations are planning a move
1C and BAS appear on Ukraine’s restricted-software list created under Cabinet of Ministers Resolution No. 1335 of 22 October 2025 and related sanctions decisions. There is no direct administrative fine for ordinary private-business use. The practical issues are continuity of updates and support, eligibility in public-sector and critical-infrastructure contexts, limited integration with modern analytics and AI, and trust expectations from partners. We compare target platforms neutrally, including MASTER, Odoo, BAF, SAP Business One, Microsoft Dynamics, ISpro and Ukrainian cloud accounting products.

What is migrated
Scope can include reference data, opening and current balances, transaction history, primary documents, relationships, custom reports and business-specific extensions. We also define what will not be moved: duplicates, technical records, obsolete reference data or logic that the target platform handles differently. Every exclusion has a reason and an agreed archive-access method. This prevents a common mismatch between an expected full replica and a delivery containing only current balances.
Parallel operation and reconciliation
The old and new systems run in parallel until control totals and selected processes are confirmed. Your team reconciles balances, turnover, documents, reports and representative transactions using agreed rules. Differences return to the transformation process rather than being silently corrected by hand. At acceptance, we hand over the data model, conversion rules and integration documentation. These assets also provide a cleaner foundation for analytics and later AI use cases.
Fit before scope
Is this the right starting point?
Use these criteria for an initial orientation. The final recommendation follows a review of your context, data and constraints.
A good fit when
- Software is restricted, unsupported or creates operational risk
- Data, history and integrations must be preserved
- Process and acceptance owners are available
Resolve this first when
- Only licence procurement is required without dependency analysis
- A target was selected without validating processes and data
- No one owns reconciliation and the cutover decision
A verifiable first stage
What you can use to make the next decision
The exact scope is agreed before work begins. These are typical decision artefacts, not promised business results.
Dependency inventory
Versions, users, processes, data, integrations and critical support dates.
Replacement-wave plan
Target options, sequence, parallel operation, training and rollback path.
Acceptance rules
Reconciliations, control operations and evidence your team will use to approve the result.

Answer first
How should you choose a replacement?
A safe replacement of 1C or BAS starts with an inventory of accounting environments, customisations, integrations and reporting—not with selecting a new product. The target platform is chosen after financial, management and statutory accounting requirements are recorded.
Process fit
Required accounting models, source documents, approvals and statutory reporting are supported.
History transfer
Reference data, balances, open transactions and the agreed history depth can be migrated.
Solution control
Documented integrations, roles, audit trails, backups and the ability to change providers.
Evidence of completion: Completeness is demonstrated through turnover and balance reconciliation, control documents and an agreed parallel-run period.
Frequently asked questions
Frequently asked questions
How long does migration take?
The supplied project guidance ranges from three months for standard accounting to nine months for a highly customised configuration. Exact timing follows configuration discovery.
Are private companies fined for using 1C?
There is no direct fine for ordinary private-business use. Restrictions apply to public bodies, state enterprises and critical infrastructure; other organisations face operational and reputational considerations.
Can historical records remain accessible?
Yes. Discovery defines which history belongs in the live system and which records should remain in a controlled, searchable archive.
