Peppol explained
What is Peppol?
Peppol is an international network that allows businesses and governments to securely send and receive e-invoices. In Belgium, Peppol is the standard for B2B e-invoicing.
A Peppol invoice is a structured digital document (UBL format) that computers can process automatically. Don't worry: in Cleero, you'll see it as a normal invoice. We handle all the technical processing in the background.
