Since 1 January 2026, every VAT-registered business established in Belgium must issue and receive structured e-invoices for domestic B2B transactions. PDF and paper no longer qualify. Our guide to the mandate covers scope and timelines; the government’s own guidance sits on the Belgian e-invoicing portal.

UBL 2.1, aligned with EN 16931. Belgium imposes no national CIUS, so invoices stay interoperable across Europe.
Access point to access point, with no government clearance and no pre-issuance validation by the tax authority.
The original structured UBL/XML file, not a PDF rendition. Cloud storage and other EU member states are allowed.
Progressive per infringement since the tolerance period ended on 31 March 2026. Buyers can also lose their input VAT deduction.

Integrate in days rather than quarters: a clean REST API, a free sandbox, quickstart guides, and support from engineers who know the mandate.
