Peppol(Peppol)
Pan-European Public Procurement On-Line — an open, four-corner network for exchanging electronic invoices across borders, now adopted as the basis of mandates in the EU, Singapore, Australia, Malaysia, and others.
Peppol (Pan-European Public Procurement On-Line) is an interoperability framework, not a piece of software. Buyers and sellers connect to certified Peppol Access Points; the network handles routing, validation, and delivery of structured documents.
Four-corner model
Sender → Sender's Access Point → Receiver's Access Point → Receiver. Either Access Point can serve any participant, breaking the historical lock-in of bilateral EDI connections.
