Frequently asked questions
Is e-invoicing mandatory?
Yes — as of 1 January 2025 e-invoicing is mandatory for B2B transactions in Germany. Businesses must already be able to receive e-invoices today.
What is the difference between ZUGFeRD and XRechnung?
ZUGFeRD is a hybrid format (PDF + XML) — ideal for B2B. XRechnung is plain XML — also usable for B2B and mandatory for public-sector contracting authorities (B2G). Our app supports both.
Where is my data stored?
All invoice data is stored exclusively locally on your device (SQLite). For PDF generation, data is processed temporarily and encrypted on our server and deleted no later than 24 hours.
Can I try the app for free?
Yes — you get a 30-day free trial with all features, no credit card required. Afterwards you can continue with an affordable subscription.
Which tax rates are supported?
The German VAT rates: 0%, 7% (reduced) and 19% (standard). Mixed tax rates within a single invoice are supported.
