End-to-end walkthrough · 4 min · no narration, all real product
From inbox to DATEV in four steps.
Every step in the video matches how the product works for real customers today.
Invoice capture
Cortena picks up invoices from your shared inbox, a drag-and-drop upload, or structured formats like ZUGFeRD and UBL. Duplicates are flagged before they enter the queue.
AI coding
Each invoice gets a GL account (SKR03 or SKR04), cost centre, VAT code, and payment terms. Every field shows the AI's reasoning. Your team reviews, not re-enters.

Approval routing
Cortena routes each invoice along the approval matrix you set. Per-line lanes, thresholds, reject-with-reason. Finance leads approve in a click; exceptions go to the CFO.
DATEV export
Approved invoices are batched and pushed to DATEV Unternehmen online via Rechnungsdatenservice 1.0. Documents land directly in your archive. No manual re-entry.

What to expect from the demo.
Do I need to prepare anything?
Nothing formal. Bring two or three recent invoices from your own suppliers and we will code them live. Seeing your own data is the fastest way to judge the accuracy.
How long is the session?
45 minutes. We spend roughly 15 minutes on the recorded walkthrough, 20 minutes on live processing of your invoices, and 10 minutes on questions and next steps.
Which accounting systems do you support?
DATEV Unternehmen online, Exact Online, and Twinfield are live today. More integrations are on the roadmap. We will confirm fit during the demo.
Is this a sales call?
It is a working session. We show the product running on real data. If it is a fit, we talk about starting a trial. If it is not, we say so.
