2026 Peppol Mandate Readiness Checklist

You have a valid Belgian enterprise number (BCE/KBO)

Your BCE number is the foundation of your Peppol participant ID. Without a valid, active BCE number your business cannot be registered on the Peppol network.

You know your Peppol Participant ID

Your Peppol Participant ID is derived from your BCE number (format: 0208:XXXXXXXXXX). Suppliers and clients need this ID to send invoices to you, and you need it to send to them.

Your software connects to a certified Peppol Access Point

You cannot connect to the Peppol network directly. You need a certified Access Point — a licensed gateway that routes invoices between senders and receivers. Feen is a certified Peppol Access Point.

You can receive Peppol invoices from suppliers

The mandate is two-way. From January 2026, your suppliers must be able to send you Peppol invoices, and you must be able to process them. Ignoring inbound invoices is not compliant.

You can send Peppol invoices to Belgian B2B clients

Sending a PDF by email to another Belgian business will no longer be compliant from January 2026. Every B2B invoice must be sent through the Peppol network in UBL format.

Your invoices are structured UBL — not PDFs

PDF invoices, even when emailed, are not compliant with the 2026 mandate. Peppol requires machine-readable UBL (Universal Business Language) format so invoices can be processed automatically.

Your client and supplier data is clean and BCE-verified

Peppol routing uses BCE/VAT numbers. Invoices sent to an incorrect or missing BCE number will fail or be rejected. Dirty data is the most common cause of Peppol delivery failures.

Your accountant can process Peppol invoices from you

If you send Peppol invoices but your accountant's software cannot read them, you create an extra manual step. Most Belgian accounting packages (Exact, Yuki, Billit) are Peppol-ready — verify this.
