Berlin

June 2026 is becoming a key moment for the German and European e-invoicing landscape. In Berlin, the E-Rechnungsgipfel 2026 is taking place — the leading industry event where discussions focus on the next stage of e-invoicing development: from regulatory implementation to real-world business execution.

The E-Rechnungsgipfel is the leading German summit for electronic invoicing, bringing together experts, solution providers, and public sector representatives from across the industry. Its 13th edition takes place in Berlin from 22–24 June 2026 and accompanies the ongoing rollout of mandatory e-invoicing in Germany. Discussions at the event increasingly reflect a clear industry trend: a shift from conceptual and regulatory topics toward practical implementation and operational use in real business environments. The focus is moving from compliance frameworks to real-world execution and integration into day-to-day business processes.

E-invoicing adoption for SMEs

Is e-invoicing adoption a challenge or an opportunity for small and medium-sized businesses?

Key takeaway from Berlin

One thing becomes increasingly clear:

The technological foundation is no longer the main challenge.
Standards, formats, and infrastructure are already widely implemented. The main focus is now shifting toward how these standards are actually integrated into business processes — including organizational change, system integration, and day-to-day operational execution.
This shift from technical readiness to real operational implementation is becoming one of the central themes of the discussions.

We see this transformation every day in real projects:

→ Integration of multiple standards and country-specific requirements
