FAQ
What is EN 16931?
EN 16931 is the European standard for electronic invoicing. It defines a semantic data model and business rules that all EU e-invoices must follow, regardless of syntax (UBL or CII).
Is EN 16931 mandatory?
For B2G invoices to EU public sector, yes. For B2B, it depends on the country. Under ViDA (VAT in the Digital Age), EN 16931 compliance will become essential across the EU.
What syntax should I use for EN 16931?
EN 16931 supports two syntaxes: UBL 2.1 and UN/CEFACT CII. UBL is more common for Peppol; CII is used in ZUGFeRD/Factur-X. Both express the same data.
What's a CIUS?
A CIUS (Core Invoice Usage Specification) is a national adaptation of EN 16931. Examples: XRechnung (Germany), Peppol BIS (international), CIUS-RO (Romania).
How do I prepare for ViDA?
Start by ensuring your invoices comply with EN 16931. Our validator checks all the business rules that will be required under the ViDA e-invoicing mandate.
