PEPPOL Electronic Invoicing in Belgium – Everything you need to know (2026)
PEPPOL is the European electronic invoicing network that becomes mandatory in Belgium from 2026. This guide explains what PEPPOL is, why it is essential for your business, and how InvoX helps you be compliant.
Belgium makes structured electronic invoicing via PEPPOL mandatory for all B2B transactions. Choosing compatible software like InvoX guarantees you compliance, security and automation.
What is PEPPOL? (simple explanation)
PEPPOL (Pan-European Public Procurement On-Line) is a secure European network that enables the automatic exchange of electronic invoices between businesses (B2B) and administrations (B2G).
Instead of sending invoices by email (PDF), PEPPOL uses a universal structured format (UBL) that can be directly read and integrated into accounting systems.
Think of PEPPOL as a digital highway for invoices: fast, secure, and interoperable with all compatible software in Europe.
In summary:
A European network: Used in 30+ countries.
Structured invoices: In UBL format (XML), directly machine-readable.
Automation: No more manual data entry needed.
Security and traceability: Every document is timestamped and certified.
