Peppol is a set of technical specifications and a governance framework, run by the non-profit OpenPeppol, that lets businesses exchange structured electronic documents without building a connection to each trading partner individually. It began in European public procurement and is now used well beyond Europe, including in Australia, New Zealand, Singapore and Japan.
It works on a four-corner model. The sender and receiver are the outer corners; each connects to a certified access point, and the two access points handle format conversion, recipient lookup, secure transport and delivery acknowledgement between them. Neither business needs to know anything about the other’s software.
Why It Matters
Peppol turns e-invoicing from an integration project into a subscription. Under traditional electronic data interchange, every new trading partner meant another bilateral connection; on Peppol, one connection reaches everyone on the network. That property is why several governments built mandates around it — Belgium’s domestic B2B mandate runs on Peppol — and why public bodies across the EU commonly accept invoices through it.
Example
A consultant registers their company number with an access point provider bundled into their accounting software. A new client in another country asks for e-invoices over Peppol. The consultant enters the client’s identifier and sends — no integration work, no file transfer arrangement, and a delivery acknowledgement comes back automatically.
Frequently Asked Questions
Can I connect to Peppol directly?
No — participation is always through a certified access point provider. Many accounting platforms include one, so you may already have access without having set anything up explicitly.
Is Peppol the same as a government e-invoicing platform?
No. Peppol is a transport network that delivers documents between businesses. Systems like Poland’s KSeF are clearance platforms where the tax authority validates the invoice before it is legally issued. They solve different problems and some countries use both.
