Belgium E-Invoice Format

Belgian e-invoices use one format: Peppol BIS Billing 3.0. This page explains the standard and why it is the only format a Belgian shop needs. PrestaShop E-Invoicing produces it from every order.

What Peppol BIS Billing 3.0 is

Peppol BIS Billing 3.0 is the invoice format of the Peppol network. It stacks three standards.

Standard	Published by	What it defines
EN 16931	CEN, the European standards body	The content of an invoice: which fields exist and what they mean
UBL 2.1	OASIS	The XML syntax that writes those fields into a file
Peppol BIS Billing 3.0	OpenPeppol	The rules every invoice on the Peppol network follows

Every Peppol BIS Billing 3.0 file is a valid EN 16931 invoice. The format covers invoices and credit notes. Access points check each file against the published validation rules, so a recipient receives only files its software can read.

Why Peppol BIS Billing 3.0 is the only format you need in Belgium

Since 1 January 2026, invoices between Belgian businesses must be structured e-invoices. Peppol is the default network for them, so every Belgian business must be reachable on it. Peppol carries invoices in Peppol BIS Billing 3.0.

Where the invoice goes	Format
A Belgian business	Peppol BIS Billing 3.0, through your Peppol access point
A Belgian public body	Peppol BIS Billing 3.0, through Peppol to Mercurius
A consumer	No e-invoice required. Your usual invoice is enough
An accountant or an ERP over FTP	Peppol BIS Billing 3.0, unless they ask for another format

Another format applies only if you and your customer agree on one. For a Belgian shop, one format covers every sale. See Belgium Regulations for the sales the obligation covers.
