Belgium

In Belgium, e-invoicing is mandatory and regulated by the Federal Public Service Finance (FPS Finance). It follows the Peppol model: invoices are exchanged via the Peppol network using the Peppol BIS format, and all records must be archived for 10 years in the electronic compliant format.

This page covers the Belgium-specific requirements that complement the General Step-by-Step Integration. Make sure you have the following taxpayer information ready before proceeding:

• tax_id_number — KBO/BCE number
• vat_id_number — Belgian VAT ID / VATIN
• credentials — Belgian fiscalization credentials
• name — registered legal name and trade name of the company or individual
• address — registered legal address of the company or individual

📘Important

As described in the general integration guide, the recipient of an e-invoice is required to be a BUSINESS type and the invoicing block is required to be populated. For Belgium, this means setting invoicing.type = PEPPOL and invoicing.identifier to the recipient’s Peppol Network Identifier, otherwise the e-invoice cannot be transmitted via the Peppol network.
