Three free tools for the most common questions about e-invoicing obligations - from applicability to format selection to routing ID verification. All entries remain in your browser.

Without registration Without data transfer Current BMF letter 10/2025

How to use the tools together

The three tools logically build on each other, from clarifying impact to concrete implementation.

1

Clarify duty

Start with the duty checker. You will learn when which duties apply and what risks exist.

2

Select format

When duty calls, use the format selector to decide whether XInvoice, ZUGFeRD or a hybrid approach fits.

3

Validate Leitweg ID

For official invoices, use the routing ID checker to verify that your addressing is correct.

Why these tools?

🔒 Full GDPR compliance

All calculations take place exclusively in your browser. No data transfer, no cookies, no tracking. Even sensitive routing IDs remain local.

📚 Based on official standards

The logic is based on the BMF letter of 10/15/2025, the KoSIT specification Leitweg-ID 2.0.2, and the current versions of XRechnung (3.0.2) and ZUGFeRD (2.4).

👥 From SAP consulting practice

The tools are developed from the questions we have encountered in SAP projects since 2013. Every recommendation is proven in practice in B2B and B2G business.
