GoBD-aligned, from capture to posting.
Cortena is built so every invoice you process keeps a complete, tamper-evident trail, in line with the principles German finance teams work to under the GoBD.
The original document travels with the booking
When Cortena captures an invoice, the original document is stored and linked to its booking. The source and the posting stay together, so an auditor can trace any number back to the invoice it came from.
An immutable, timestamped log
Every capture, edit, and approval is recorded with a timestamp and cannot be altered after the fact. Changes are appended, not overwritten, so the history of each invoice is complete and verifiable.
Traceable coding and approvals
The account, tax key, cost centre, and approval decisions attached to each invoice are logged with who did what and when. This gives you the traceability GoBD principles expect, end to end.
What this means for you
The original invoice is always linked to its booking.
Edits are logged and immutable, never overwritten.
Coding and approvals are recorded with who, what, and when.
Your Steuerberater and auditors get a clean, verifiable trail.
