The Belgian Peppol Authority (BOSA) follows the standard OpenPeppol framework; Hermes and the Mercurius platform cover B2G flows. No additional local accreditation is required for Service Providers serving Belgian businesses.

Penalties

Non-compliant invoices can be refused by the recipient and administrative fines apply for failing to issue structured invoices (escalating for repeat offences). VAT deduction can be challenged when no compliant invoice exists.

Frequently asked questions

Is Peppol mandatory for B2B invoices in Belgium?

Yes. Since 1 January 2026, established VAT-registered businesses must exchange structured electronic invoices; Peppol BIS over the Peppol network is the default method unless both parties agree on another EN 16931-compliant channel.

Do foreign companies invoicing Belgian customers need Peppol?

The mandate targets invoices between businesses established in Belgium, but Belgian customers increasingly refuse PDFs; foreign suppliers connect voluntarily to keep invoicing frictionless.

What do small companies without an ERP do?

A hosted portal or an e-mail gateway is enough — you can receive and send compliant Peppol invoices without any accounting software integration.
