This article breaks down the Peppol transport model in a simple way, showing how electronic invoices move securely from sender to receiver through trusted Access Points. Learn how the Peppol infrastructure enables reliable document exchange without complex one-to-one integrations, and why the model has become the foundation for modern e-invoicing across Europe and beyond.

It ensures interoperability and avoids vendor lock-in. Traditional e-invoice (VAN) networks rely on bilateral agreements, creating a fragmented ecosystem.

PDFs and paper invoices will no longer suffice. The framework also prepares Belgium for near real-time VAT e-reporting by 2028, with penalties for non-compliance already defined.
