Frequently asked questions
Do I need to send all my invoices via Peppol?
No, only if the invoice is sent to a business (with a company number) subject to VAT. Peppol does not apply if you send an invoice to a private individual.
If my client is European, do I need to send via Peppol?
Currently, electronic invoicing is an obligation managed at the country level. Belgium has decided to make it mandatory from 2026, but each country has its own deadlines. It is only in 2030 that the obligation will apply across the whole of Europe.
What should I do if my client is not available on Peppol?
There is nothing to do — you simply continue sending your invoice as normal.
Is there a list of clients registered on Peppol?
Yes, there is a public directory. You can consult it if you wish. However, it is not necessary — BILLY handles this automatically for you when you create or import your invoice.
Is there an additional cost?
No, the connection to the network and the transfer of your invoice are included in your BILLY subscription.
How can I track the sending of my invoice on the Peppol network?
