Invoice capture and e-invoicing

Every invoice in. Nothing to chase.

Suppliers send, Cortena reads. Every invoice captured field for field, together with the emails and documents around it, whether it arrives as an e-invoice or a scanned PDF.

Move your cursor over the invoice. Cortena reads the fields the way it reads a real one.
One address per team

Forward once. Every invoice lands in the right place.

Each tenant gets a dedicated inbox address. Tell your suppliers once, or auto-forward from your accounting mailbox, and invoices arrive in Cortena the moment they are sent.

  • A dedicated inbox address per entity, with root-mailbox routing for multi-entity groups.
  • Drag and drop PDF, PNG and JPG straight into the workspace when you have paper or a scan.
  • Structured e-invoices are recognised on arrival and read without a single OCR pass.

The Cortena Chrome extension, capturing an invoice from a supplier portal.
Supplier portals

Invoices locked in a portal? We fetch them.

Some suppliers only post invoices inside their own portal. Set it up once with the Cortena Chrome extension, and we pull each new invoice every month into the same inbox as everything else.

E-invoicing

We support e-invoicing across Europe.

Cortena reads the structured e-invoice standards directly, and falls back to reading the document itself when an invoice arrives as a plain PDF.

Clean on the way in

Duplicates caught. Missing fields flagged.

Every captured invoice runs through duplicate detection and completeness checks as it arrives. What passes is clean. What does not is held with a clear reason.

  • Duplicate detection on supplier, invoice number and amount, so nothing is paid twice.
  • Completeness checks on VAT ID, invoice number, date and totals against the line items.
  • Anything that fails is held for review with the reason spelled out, never silently passed.
Context stays attached

Every invoice keeps its full context.

Cortena captures more than the invoice. The email it arrived in and the documents around it stay attached, so the delivery note, the order or the contract is one click away, without leaving the invoice.

Questions

Invoice capture, answered.

  1. Each tenant gets a dedicated inbox address. Suppliers email invoices there, or you auto-forward from your accounting mailbox, and they arrive in Cortena instantly. You can also drag and drop PDF, PNG and JPG files straight into the workspace.

  2. Cortena reads UBL, CII, and hybrid ZUGFeRD and Factur-X, all aligned to the EU standard EN 16931. Structured fields are read directly from the file. Plain PDFs and scans use an AI fallback that reads the document itself.

  3. Yes. Every captured invoice is checked against supplier, invoice number and amount on capture. Suspected duplicates are held for review rather than passed through, so nothing gets paid twice.

  4. A scan or photo is read the same way a person would read it. Cortena extracts the supplier, amounts, dates, VAT ID and line items, then runs the same completeness checks as a structured invoice.

  5. Yes. Each invoice keeps a badge that opens the originating email conversation, up to 50 messages. You can read the thread, open the original attachment and check what was agreed without leaving the invoice.

  6. Invoices are processed on servers in Germany with AES-256 encryption, and we never train AI on your data. The GoBD-aligned archive of record stays in DATEV, so your books and your audit trail sit where your accountant expects them.

  7. Still have a question?

Stop typing invoices in.
