®Belgium B2B e-invoicing integration (Peppol)
Belgium's mandatory structured B2B e-invoicing is in force. PDFs no longer count for domestic B2B: invoices must be structured (EN 16931, Peppol BIS 3.0) and exchanged over the Peppol network. We connect your software to a Peppol Access Point so you issue and receive compliant invoices.

Structured B2B e-invoicing has been mandatory for domestic transactions since 1 January 2026. Belgium uses the Peppol four-corner model, not a central portal.

What is Mandatory B2B structured e-invoicing (Peppol) in Belgium?
Since 1 January 2026, Belgian VAT-registered businesses must issue and receive structured electronic invoices for domestic B2B transactions. A PDF emailed to a customer no longer satisfies the requirement for in-scope transactions: the invoice has to be a structured document in the EN 16931 standard, and Peppol BIS 3.0 is the safe default.
Belgium did not build a central government portal. It uses the Peppol four-corner model, where certified Access Points exchange documents between your system and your customer's. A near real-time e-reporting layer is planned for 2028 but is not yet mandatory.
We connect your software to a Peppol Access Point and the right format so both issuing and receiving just work.
A complete Belgium integration.
Whether you run an off-the-shelf ERP, a cloud accounting app, or a POS you built in-house, we make it comply with Mandatory B2B structured e-invoicing (Peppol), end to end.

Built into the software you already run.
We connect your ERP, accounting, or billing software to the Peppol network and the EN 16931 / Peppol BIS 3.0 format, so you issue and receive compliant structured invoices with your Belgian partners. If your system cannot be adapted, we build one that can.
Because Belgium uses Peppol, the same connection often covers other Peppol countries you trade with.
