E-invoicing in Belgium
Since 1 January 2026, structured electronic invoices between Belgian VAT-registered businesses are mandatory, exchanged over Peppol (Peppol BIS). Confirm your obligations with the FOD Financiën / SPF Finances.
Invoice Forever can export a structured EN 16931 / Peppol BIS (UBL) e-invoice alongside the PDF (beta) — the format most of these mandates are built on. You still send it via your own access point, and some countries require their own national format.
