Belgium has adopted a clear timeline: from 1 January 2026, VAT‑registered businesses must issue and receive structured electronic invoices for almost all B2B transactions. PDF by email or portal download will no longer meet legal requirements; invoices must flow system to system in a standard format.
This reform sits within a broader legislative effort to modernise invoicing and public procurement. The law was formally approved, with B2G e-invoicing already required for contracts published after March 1, 2024. The end goal is straight‑through, secure processing that reduces errors, speeds payment, and supports audit and VAT controls.
The 2026 obligation applies in Belgium only, for domestic B2B transactions. The EU is moving toward cross-border e-invoicing and digital reporting in the coming years; as that agenda advances, the Netherlands and Luxembourg can expect complementary mandates aligned with EU standards.
Benefits for accounting teams:
- Lower processing cost per invoice and fewer manual touchpoints.
- Better protection against invoice fraud through structured, verifiable data.
- Faster matching, status updates, and payment reconciliation.
How Peppol works in practice
Belgium’s model relies on the Peppol network. Peppol is not a portal; it is a four‑corner, standards‑based network. Each company connects via an accredited service provider (Access Point). Once connected, buyers and suppliers can exchange e‑invoices in a common specification without bespoke integrations.
Addressing Peppol uses participant identifiers (endpoint IDs) published via service metadata, so senders and receivers are discovered and routed correctly. In short, your Access Point and identifier make the link that keeps invoices flowing.
