Migrate your books and opening balances

Use Accounting → Setup → Opening & migration for company opening balances and DATEV bookkeeping. Do not feed a double-entry booking stack into the ordinary bank-statement import.

If you only want contacts, invoices or receipts from supported software, use the separate software migration guide. That is not a replacement for transferring the complete Ledger.

1. Choose your starting point

• New GmbH / UG: build opening entries from the corporate tax registration record.
• Switch from 1 January: bring the previous closing balances into the new fiscal year.
• Switch during the year: bring opening balances and all bookings through the last day in the old system.
• Start from the previous year's books: provide the complete source-year books so Norman can derive the following year's opening balances.

Example: to start on 1 January 2025 using full 2024 records, select the previous-year scenario. Set the source period to 2024 and the target fiscal period to 2025. Do not put 2024 bookings into a 2025 mid-year period.

2. Add and analyse the records

1. Gather the opening-balance export, all relevant DATEV booking stacks including closing adjustments, and the final trial balance (SuSa).
2. Use Analyze files to review the detected SKR, covered periods, file roles, evidence and warnings. PDF reports can support detection and reconciliation; image-only documents may use AI/OCR.
3. Confirm Use this setup only after checking it. Analysis alone does not change the Ledger. Applying a different detected SKR does change the company framework.
4. Supply machine-readable DATEV/CSV in the appropriate import fields. A PDF trial balance is not, by itself, a complete booking import.
5. Alternatively, enter balances manually with account, debit/credit side and amount. For a mid-year manual snapshot, do not also import the bookings already represented by that snapshot.

3. Reconcile and confirm

Choose Preview & reconcile. Resolve missing accounts, mapping errors and date mismatches. Compare all closing/opening balances, bank, cash and the carried result with the source records, not just the grand total.

For the previous-year scenario, source income and expenses stay in the source year; the new year receives opening balances and the carried result, not duplicate 2024 transactions.

Only when the preview is ready and reconciled should you confirm the import. The confirmation can replace the existing cutover import for that fiscal year: read it before proceeding.

Continue without duplication

For a year-start migration, import new bank activity from the first day of the target year. For a mid-year switch, start on the day after the cutover date. Check the Ledger before importing overlapping data again.
