E-invoicing is mandatory in Belgium. Are you ready?
Since January 2026, B2B e-invoicing is mandatory in Belgium. NELIOX integrates Peppol and Belgian specificities from the ground up so the transition feels natural.
The Belgian **timeline**
Belgium is moving toward 100% electronic invoicing. Here are the key milestones.

Peppol adoption by Belgian administrations and businesses
What exactly **is** Peppol?
Peppol (Pan-European Public Procurement OnLine) is a standardized network for exchanging electronic business documents, particularly invoices.
In Belgium, the Peppol network has become the standard for B2B e-invoicing. Each business has a Peppol identifier (based on its BCE/KBO number) to send and receive structured invoices.
It's not just a PDF sent by email. It's a structured format (UBL/XML) that enables automatic processing by accounting systems.
How does it work?
You create your invoice in NELIOX as usual
NELIOX automatically converts it to Peppol BIS 3.0 format
The invoice is sent via the Peppol network to the recipient
