You define the flow. Cortena runs it on every invoice.
After an invoice arrives, you decide how it moves inside Cortena: how it is validated, how each line is coded, and when it is flagged for a person.
See a standard flow run live across four chapters. With the Workflow Builder, the possibilities are endless.
It starts in the inbox.
Forward your invoice inbox once. Email, PDF and e-invoices in ZUGFeRD or XRechnung are read down to the line, and duplicates are caught before they reach your team.
See how invoice capture worksCoded like your best bookkeeper would.
Every line gets a GL account, cost centre and VAT key, on your chart of accounts and the patterns Cortena learned from your books. Sure of the pattern, it codes with confidence; unsure, it flags the line instead of guessing, on the rules you set.

Your approval matrix routes each invoice by amount, cost centre and entity. Approvers sign off in one click from Slack or email, delegation covers holidays, and every decision is logged.
Set up your approval matrixHanded to your ledger, booking-ready.
Approved invoices join a posting batch with the account, VAT key and cost centre on every row and the original document attached. One click sends it to DATEV Unternehmen online. Exact Online and Twinfield are served the same way.

You design the flow, and the points of control along it. Approve every single invoice if that is what you want. Give Cortena more room as your confidence grows. Either way, every step is logged and traceable.

The numbers finance teams hold us to.
After the first weeks of corrections, around 90% of invoices are coded end to end without anyone touching them.
The invoices that do need a human take about 30 seconds each. A review and a click, not ten minutes of keying.
Your pilot is live in 1 day. Test it on real invoices, and scale when it is proven.

Everything finance leads ask before they run a week of real invoices through Cortena.
Cortena captures invoices from a forwarded email inbox, direct PDF uploads, and e-invoice formats including ZUGFeRD and XRechnung. It extracts header and line-item data from every document and flags duplicates before they reach your team.
After a short learning period on your books, around 90% of invoices are coded to the right GL account, cost centre and VAT key without a human touch. Lines Cortena is unsure about are flagged for review, and nothing posts until you approve.
Yes. Cortena codes to SKR03 or SKR04 with the correct BU key and cost centre for DATEV, and maps to your chart of accounts in Exact Online and Twinfield in the same way.
You define an approval matrix with amount thresholds, delegation and multi-entity routing, all in the interface. Approvers are nudged in Slack or email and sign off in one click, and every decision is logged with who approved and when.
Cortena keeps GoBD-aligned records. Every step from capture to posting is logged and tamper-evident, and the original document stays attached to its booking. All data is hosted in the EU.
Most teams are live within 15 days. Setup means forwarding your invoice inbox, connecting your ledger, and mapping your accounts and approval rules. There is no IT project.
