How Peppol Works

The Peppol network uses a 4-corner model to enable secure, standardized e-invoice exchange between businesses: Peppol 4-Corner Model
  1. Corner 1: Your business (the sender)
  2. Corner 2: Your Access Point (e-invoice.be)
  3. Corner 3: Recipient’s Access Point
  4. Corner 4: Recipient’s business
e-invoice.be handles all the technical complexity of Peppol transmission, so you can focus on your business.
