Introduction

NIZU Peppol UBL Invoice 2.1 is NIZU’s integrated solution for electronic invoicing (e-Invoicing) in compliance with Belgian and European Peppol standards.

It enables businesses to create, send, and receive legally recognized digital invoices that meet all government and cross-border requirements—without manual intervention.

The term UBL (Universal Business Language) refers to the standardised XML format used for electronic business documents, ensuring full interoperability between accounting systems, ERP platforms, and public administration portals.

Peppol (Pan-European Public Procurement Online) is the secure network used by European companies and governments to exchange these e-invoices safely and reliably.

Why It Matters

Since January 2026, all companies operating in Belgium will be required to issue and receive electronic invoices using the Peppol network.

By adopting NIZU’s Peppol UBL 2.1 integration now, your organization will be fully compliant, audit-ready, and technologically aligned with future EU digital invoicing policies.
