Bookkeeping core
Lexware Office
SKR03 and SKR04 are both supported, switching migrates all existing bookings automatically, and the fiscal year is the calendar year with calendar-month booking periods. Immobilization can be triggered manually to any chosen date or runs automatically each month with a protocol of every execution — a genuine period lock, and the DATEV batch-booking export shows a real ledger underneath. We found no public information on cost centres, recurring and reversing entries, accruals, opening balances, or multi-year comparatives.
Xero
The evidence evidences invoicing, bill entry, bank reconciliation and reports — the pretty screens — but not one word about double-entry, a chart of accounts, a journal, opening balances or a period close. No SKR03/SKR04 anywhere, so as evidenced there is no German ledger underneath at all.
