The mandate
From 1 January 2026, every VAT-registered Belgian business must send structured electronic invoices to its Belgian B2B customers over the PEPPOL network. PDFs and paper invoices no longer satisfy the legal requirement between Belgian taxable persons.
The format is PEPPOL BIS Billing 3.0 (a UBL profile of EN 16931). B2G has been mandatory since 2022 via Mercurius; the 2026 step extends the same network to B2B.
Who is in scope
All Belgian VAT-registered taxable persons issuing invoices to other Belgian taxable persons. Small businesses under the franchise (KOR) and certain exempted sectors are out of scope for issuing but must still be able to receive.
Sales to private individuals (B2C) and cross-border transactions are out of scope for the Belgian mandate — though the PEPPOL network handles them too.
Routing identifier
Each participant is addressed by their PEPPOL ID. In Belgium this is built from the KBO/BCE enterprise number under scheme 0208 (e.g. 0208:0123456789).
Before you send, the recipient must be registered on the PEPPOL directory. Eurobillr looks them up automatically and warns you if they are not yet reachable.
Zo doet Eurobillr het
- Registered PEPPOL access point — your KBO/BCE number is your PEPPOL ID.
- Outbound: every Belgian B2B invoice is emitted as PEPPOL BIS Billing 3.0 UBL and delivered through the network.
- Inbound: vendor invoices arrive directly into your expenses with the PDF rendition attached.
- Intervat-ready: the periodic VAT return and intra-community listing pre-fill from your real invoices.
