Introduction

NIZU XRechnung UBL 3.0 is NIZU’s official integration for Germany’s electronic invoicing standard, based on the European Norm EN 16931.

It allows companies to create, validate, and transmit e-invoices in full compliance with German federal and state-level regulations, using the UBL (Universal Business Language) format.

The XRechnung format is a structured XML-based electronic invoice designed to ensure accuracy, transparency, and interoperability across public and private sectors in Germany.

This system supports B2G (Business-to-Government) invoicing and is increasingly adopted in B2B (Business-to-Business) transactions as part of Germany’s digital transformation in finance.

Why It Matters

Since November 2020, electronic invoicing has been mandatory for all suppliers doing business with German federal authorities.

By adopting NIZU XRechnung UBL 3.0, your organization ensures:

• Full legal and technical compliance with German and EU e-invoicing laws.

• Secure and standardized communication with public entities through official channels such as ZRE (Zentrale Rechnungseingangsplattform des Bundes) and OZG-RE.

• Future readiness for the upcoming B2B e-invoicing mandates expected in Germany.
