e-invoicing in Belgium

Belgium is standardising electronic invoicing across both public and private sectors. Suppliers to the government must already send e-invoices in a structured format (typically Peppol BIS Billing 3.0) in line with EU requirements, and from 1 January 2026 e-invoicing became mandatory for most B2B transactions between Belgian VAT-registered companies. The Peppol network is the primary channel for exchanging structured invoices, and Belgium is progressing toward broader digital reporting and compliance with EU ViDA initiatives.

Belgium company account

When registering a new Belgian company via the API, the CBE/KBO enterprise number must be used as the company identifier. At the moment, company registration requires the vendor to have KYC approval from Maventa. Contact Maventa support to get started.
