Understand the basics

What is Peppol?

Peppol (Pan-European Public Procurement Online) is a standardised European network for exchanging electronic business documents between companies. It is based on the structured UBL 2.1 format, an XML file readable by accounting systems, tax authorities and invoicing software.

A network, not software
Peppol is an exchange infrastructure, like SWIFT for banks. Your invoicing software sends documents via this network to any participant.
UBL 2.1 format
Each Peppol invoice is an XML file structured according to the UBL 2.1 standard, containing all fiscal information required by the Belgian tax authority (SPF Finances).
Already mandatory in B2G
Since 2024, invoices to Belgian public authorities must go through Peppol. In 2026, this obligation extends to all B2B transactions.
European recognition
Peppol invoices are recognised across the European Union. One format, one connection, for all your Belgian and European clients.
