Peppol '4 Corner' Model

The Belgian mandate is built entirely on the Peppol network. Understanding Peppol is essential to understanding the ClearTax solution.

Peppol (Pan-European Public Procurement Online) is not a single platform but a secure, open network designed to exchange electronic business documents, including e-invoices.

It functions similarly to a telecommunications network: just as a customer on one phone network can call a customer on any other network, a business on the Peppol network can transact with any other business registered on the network, regardless of their software or service provider.

This system operates on a 4-Corner Model:

1. Corner 1: The Sender (Your business)

2. Corner 2: The Sender's Access Point (Your service provider, e.g., ClearTax)

3. Corner 3: The Receiver's Access Point (Your customer's service provider)

4. Corner 4: The Receiver (Your customer)

This decentralized model is fundamentally different from centralized government portal systems. For B2B transactions in Belgium, businesses do not upload invoices to a single government website. Instead, compliance is achieved by exchanging the structured invoices directly with trading partners through the secure Peppol network, using a certified Access Point. This makes the choice of an Access Point the most critical compliance decision for a Belgian business.
