Why has e-invoicing suddenly become so important? (and especially from 2026!)

To dive straight into your accounting software: e-invoicing is becoming the new standard for B2B invoices. The Belgian government has confirmed that structured electronic invoices will be mandatory for almost all B2B transactions from 1 January 2026.

In practice, this means PDFs and paper invoices are no longer sufficient for the B2B market. E-invoices are exchanged in a machine-readable way, following the European EN 16931 standard. Only then you'll be fully compliant.

Did you know that...

- EN 16931 is the European standard for electronic invoicing?
- It was published in 2017 by the European Committee for Standardization (CEN)?
- This set of rules and methods makes invoices uniform, interoperable and automatically processable across the EU?

What will change for SMEs and startups?

You invoice in a structured format (e.g. UBL XML) instead of PDF.
Your invoices are exchanged via Peppol: secure, controlled and traceable.
Software (such as B2Brouter) performs validations before sending and provides status updates (delivered, rejected, paid, etc.).
The result: fewer errors, faster payment and less administration.

Peppol uitgelegd in één minuut

No, Peppol is not a new Pokémon, but the network that connects businesses and public authorities to exchange e-invoices securely and in a standardised way. With a Peppol ID, your invoice finds the right recipient, and everything moves much faster than a registered letter. In short: thanks to the international Peppol network, you send and receive electronic invoices safely and lightning fast.
