How to send your first PEPPOL e-invoice

PEPPOL lets you deliver a structured invoice straight into your customer's accounting system — no PDF, no email. From 1 January 2026 it is mandatory for Belgian B2B. Here is how to send your first one in Eurobillr.

1. Register your PEPPOL participant ID

Go to Peppol → Register. Eurobillr registers you on the network using your enterprise number (in Belgium, your KBO/BCE number under scheme 0208). Registration is a one-time step and usually completes within a day.

2. Check that your customer can receive

Open the client and enter their VAT or enterprise number. Eurobillr looks them up in the PEPPOL directory and shows whether they can receive e-invoices. If they are not yet registered, you can still send a PDF in the meantime.

3. Create the invoice as usual

Add your lines, set the VAT rate, and pick the right VAT mode (standard, reverse charge, exempt). Eurobillr fills the legally required fields and keeps your numbering gap-free.

4. Send over PEPPOL

On the invoice, choose Send → PEPPOL. Eurobillr builds the PEPPOL BIS Billing 3.0 (UBL) document, validates it against the rules, and routes it through a certified access point. You will see the delivery status update as the network confirms receipt.

Tip: if validation flags a missing field (for example a customer VAT number for reverse charge), fix it on the invoice and re-send — nothing is filed until delivery succeeds.

What your customer receives

The invoice arrives as structured data in their software, already typed and ready to book. They can also view a human-readable rendition.
