European foundation
Starting point: EN 16931
EN 16931 defines the common European foundation for structured invoice data. Many national e-invoice formats and requirements build on it. The exact requirements also depend on the country, recipient and transmission route.
Example
Relevant across Europe, with additional national rules and recipient requirements.
Relevant terms
- EN 16931
- CIUS
- UBL
- CII
- Validation
Check carefully
Use EN 16931 as the European starting point. The requirements for the relevant countries, recipients and transmission routes can then be determined.
Next step
Identify the countries and recipients you invoice. This determines the relevant formats and transmission routes.
