E-Invoicing

Ready for the Belgian B2B e-invoicing mandate

Structured e-invoicing is mandatory for Belgian B2B invoices since 1 January 2026. FAKTUUR generates compliant UBL 2.1 on the Peppol BIS 3.0 / EN 16931 profile out of the box.

  • EN 16931 / BIS 3.0 β€” The official EU profile, not a lookalike.
  • Pre-flight validation β€” Each issued invoice is checked before any XML is produced; problems are flagged, not shipped.
  • EAS participant addressing β€” Each party's electronic address uses the correct country scheme code, derived from the VAT number.
  • Tax category mapping β€” VAT rates map to EN 16931 categories, including zero-rate and exemption cases.
  • Billit integration β€” Deliver through your Peppol access point.
