What locking means
Locked records can no longer be changed, deleted, or reset. That is the GoBD-compliant immutability inside the tenant, not a later cleanup in the list.
- Choose period and record types on the locking page
- Review the preview of affected records before you confirm
- Lock invoices, dunning notices, credit notes, documents, and bank transactions
- Optionally lock the same records directly during the accounting export
- Read every run in the activity log
- Correct what is still open beforehand, because the step cannot be undone
