Peppol e-invoicing and cash flow software for Belgian SMEs

Since 1 January 2026, structured Peppol e-invoicing is mandatory for almost all B2B transactions in Belgium. Paylists is the simplest way for a Belgian SME to send and receive Peppol e-invoice from day one — and to actually get paid faster.

Belgian Peppol B2B mandate

Belgium’s B2B e-invoicing mandate is live — Paylists makes it one toggle.

Since 1 January 2026, almost all B2B invoices between Belgian VAT-registered businesses must be sent as structured Peppol e-invoices. PDFs by email no longer meet the legal requirement for most B2B flows.

The required format is Peppol BIS Billing 3.0, exchanged over the Peppol four-corner network. Belgian businesses must be able to both send and receive Peppol e-invoices from registered VAT partners.

Paylists is connected to the Peppol network. If you also bill into the Netherlands, Luxembourg or Germany, the same connection handles those flows too.

Belgian Peppol e-invoicing — questions, answered

Almost all B2B transactions between Belgian VAT-registered businesses are in scope. There are limited exemptions (e.g. very small specific cases). Cross-border invoices, B2C and certain regulated flows have their own rules. Always check your specific situation with your accountant.
No. Paylists connects to the Peppol network on your behalf. You only need a Paylists account.
Belgium runs the Hermes fallback service that delivers Peppol invoices to non-Peppol recipients by email until they connect. Paylists supports that flow automatically when needed.
Not for B2B transactions in scope of the mandate. Structured Peppol BIS is the legal requirement. PDFs remain useful for human reference and Paylists generates one alongside every Peppol XML invoice.
The Belgian legal retention period for invoices is 7 years. Paylists archives every invoice in tamper-proof (coming soon) form for the full period with a complete audit trail.
Yes — directionally. Germany’s E-Rechnung law requires receiving from 2025 and sending from 2027–2028. The Netherlands, Ireland and others are expected to follow under the EU’s ViDA framework. Paylists is built for all of it.
