Belgium is entering a new phase of digital transformation with the implementation of mandatory B2B e-invoicing starting January 1, 2026. This reform follows earlier requirements for B2G (business-to-government) electronic invoicing and aligns with the European Commission’s ViDA (VAT in the Digital Age) initiative. The objective is to improve VAT collection, reduce fraud, and streamline business processes across the internal market.
The upcoming mandate will require businesses operating in Belgium to issue and receive structured electronic invoices in B2B transactions, using compliant formats and transmission networks. B2Brouter, as a certified Peppol Access Point, facilitates secure and standardized e-invoicing according to Belgian and European regulations, ensuring full interoperability with public and private sector recipients.
