Question 1

What is EN 16931?

EN 16931 is the European semantic data model for core electronic invoice information. National formats and delivery networks can add local rules on top of that common foundation.

Question 2

Are Factur-X and XRechnung the same format?

Accepted Answer

No. Factur-X is a hybrid PDF/A-3 document with embedded CII XML, while XRechnung is a German CIUS commonly exchanged as structured XML. Both can express EN 16931 invoice data.

Question 3

Where should a business start with EU e-invoicing?

Accepted Answer

Identify the countries and buyer types you invoice, confirm the accepted format and delivery channel, map required invoice fields, then validate sample files before the mandate applies to your business.
