Bookkeeping core
Lexware Office
The chart of accounts is real — SKR03 or SKR04, switchable, with existing bookings migrated automatically — calendar months serve as the booking periods, and a monthly locking cycle stands in for the period close. We found no public information on free manual postings, journals, opening balances, cost centres or accruals, and the fiscal year is fixed to the calendar year.
Xero
The evidence evidences invoicing, bank reconciliation and 'real-time reports' — a ledger of some sort exists — but not one word on double-entry, journals, a chart of accounts, SKR03/SKR04, opening balances or a period close. I can only audit what the vendor documents, and that tops out at simplified bookkeeping with no free posting and no close.
