EN 16931 is a European standard for electronic invoicing, formally titled “Electronic invoicing – Semantic data model of the core elements of an electronic invoice.” It was developed by the European Committee for Standardization (CEN) and aims to standardize the content and structure of electronic invoices to facilitate cross-border trade and compliance with legal requirements.

Peppol BIS e-invoicing specifications are based on the EN 16931 standard, harmonizing electronic invoicing practices across Europe, promoting efficiency, reducing costs, and enabling seamless cross-border transactions.
