Belgium is moving quickly towards digital invoicing. As of January 1, 2026, e-invoicing will become mandatory for B2B transactions. But what exactly does that mean? And what should companies do to stay compliant?

In this article, we’ll explain everything you need to know about Peppol, invoice creation, VAT reverse charge, and how efactuurhub makes the transition to electronic invoicing smooth and legal.

What is e-invoicing?

E-invoicing (short for electronic invoicing) means sending an invoice in a structured digital format (like XML or UBL) instead of a PDF by email. It allows software systems to communicate directly no manual input is needed.

A correct e-invoice must contain:

Full business and VAT information
Proper general terms and conditions
Indication of VAT reverse charge where applicable
Bank account and payment details
A unique invoice number and date

Why is e-invoicing becoming mandatory in Belgium?

The Belgian government, through FOD BOSA (Federal Public Service for Policy and Support), aims to:

Reduce VAT fraud
Improve data quality
Automate the invoice process
Enable faster payments
Simplify regulatory compliance

For this reason, electronic invoicing will be mandatory for all B2B companies in Belgium.

What changes for companies?

You’ll need to:

Issue your invoices in structured XML format
Ensure all required fields like VAT reverse charge, general terms on invoice, and legal identifiers are present
Send via a secure, government-approved network like Peppol

What is Peppol and how does it work?

The Peppol network is an international standard for exchanging invoices and procurement documents digitally. Through a certified Peppol Access Point, like efactuurhub, your invoices:

Are formatted correctly
