Bookkeeping core
BuchhaltungsButler
EÜR and Bilanz modes, Summen- und Saldenlisten, Kontenblätter, cost centres and fixed-asset accounting evidence a real double-entry ledger, and association customers get SKR42/SKR49. We found no public information on opening balances, manual journal postings, or a period close with locking, so the closing discipline an audit requires is unevidenced.

Double-entry is explicitly offered ('einfache und doppelte Buchführung') with cost centres, BWA, trial balance, depreciation and a cashbook — more than an EÜR list. But the evidence names no chart of accounts, no opening balances, and no period close or locking, so the ledger underneath the screens is only partially evidenced.
