## **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.
