Peppol
Send electronic invoices through the Peppol network
Last updated on
With Peppol you send an invoice directly to the recipient's accounting system, without a PDF. Peppol is the European network for electronic invoicing. In Tillor it happens automatically: if a customer has a Peppol ID, the invoice goes along by itself after booking.
When do you use Peppol?
Peppol is mandatory for:
- Belgian B2B invoices - sending invoices to Belgian businesses with a VAT number
- Public contracts - invoicing government bodies in most EU countries
For Dutch customers Peppol is optional but supported.
From 2026, Peppol is mandatory for all B2B invoices in Belgium. Make sure the Peppol IDs of your Belgian customers are set correctly.
Setting up Peppol
Peppol for your organisation
Peppol uses the VAT number and address of your organisation. Check that these details are correct in Settings.
On the first Peppol dispatch, Tillor automatically registers your organisation as a sender in the Peppol network.
Contact Tillor support if Peppol is not yet available for your organisation.
Setting a Peppol ID for a customer
For every customer you want to invoice through Peppol:
- Go to Customers > [customer] > Invoicing
- Open Invoice Settings
- Enter the Peppol ID, or choose a recipient through the search icon
- Click Save
Do you have a Belgian customer with a VAT number? Then you cannot book an invoice until a Peppol ID is set.
Looking up a Peppol recipient
Do you not know a customer's Peppol ID? Use the search icon to the left of the field:
- Go to Customers > [customer] > Invoicing
- Click the search icon to the left of Peppol ID
- Tillor searches automatically based on the customer's VAT number
- Select the right recipient from the results
Not all businesses are registered in the Peppol network. If a business is not found, you can still send the invoice by e-mail.
Sending invoices through Peppol
When a customer has a Peppol ID, Tillor sends the invoice through Peppol automatically after booking:
- Create the invoice as usual
- Check that the customer's Peppol ID is set correctly
- Check the lines and amounts on the draft invoice, then click Book invoice
- Tillor sends the invoice automatically through the Peppol network (usually within a few minutes of booking)
Checking the send status
Open the booked invoice and look at Events in the right-hand panel. Here you can see whether the invoice was sent through Peppol, or whether sending or delivery failed.
What happens next?
- The invoice is sent automatically as soon as you book it. You do not have to send anything.
- An invoice that was sent through Peppol gets the label Sent via Peppol in the list on the customer profile.
- You can no longer set such an invoice back to draft or move it to another customer. You correct it with a credit invoice. See Correcting an invoice.
- If sending fails, you see that under Events on the invoice and there is a notice under CommunicationNotifications. Then send the invoice by e-mail, see Sending an invoice.
