Peppol Network Meetings Kassel: Key Updates on e-Invoicing, XRechnung and Peppol Standards
📅 November 12-13, 2025 🏢 KoSIT Germany ⏱ 2 min read
The Peppol Network Meetings on 12–13 November in Kassel provided valuable insights into the latest developments in electronic invoicing in Germany, the XRechnung format, and evolving Peppol standards. We extend our sincere thanks to all participants, and to KoSIT and Beate Schulte, for their contributions and excellent organisation.
Focus on e-Invoicing Mandates and XRechnung
The first day marked the one-year anniversary of the German e-invoicing mandate. Participants received updates on current facts, implementation experiences and compliance requirements in B2G and increasingly B2B scenarios. The interactive sessions helped identify practical improvements for digital invoice processes.
A highlight of the day was the exclusive tour of GRIMMWELT, demonstrating how far digital information processing has come compared to historical documentation methods.
Technical and Regulatory Developments in Peppol
The second day focused on technical and regulatory developments, including upcoming adjustments to Peppol BIS, potential effects on national formats like XRechnung, and best practices for compliant cross-border invoice exchange.
