Systematic Invoice

E-invoices

Send invoices that accounting systems read by themselves. Systematic Invoice exports two European formats, both following the EN 16931 standard:

  • UBL 2.1 compliant with Peppol BIS Billing 3.0, used across Europe and beyond.
  • XRechnung 3.0, required by public bodies in Germany.

Turn them on

In Settings, turn on UBL 2.1 or XRechnung, or both. An invoice then offers Export UBL XML, Export XRechnung XML, and Export PDF (UBL embedded): a normal PDF with the e-invoice inside it.

Save the invoice before exporting, so the file matches what you see.

What they need

The app tells you what is missing before it exports. Usually:

  • Your business: country code, VAT code or company code, and for Peppol its endpoint id and scheme. XRechnung also needs your email and phone.
  • The client: country code, address, a buyer reference (for XRechnung, the Leitweg-ID), and for Peppol its endpoint id and scheme.
  • A due date.

Write addresses as Street, City, Postal code, Country so they are read correctly.

Foreign currencies

An invoice in another currency carries its VAT total in your default currency too, as the standard asks.
