Frequently asked questions
Is e-invoicing mandatory?
Since 1 January 2025, every business in Germany must be able to receive and process e-invoices — regardless of size or turnover.
The obligation to send them is phased in:
- Until 31 Dec 2026: paper and ordinary PDF may still be used for sending, provided the recipient agrees.
- From 1 Jan 2027: sending becomes mandatory for businesses with more than EUR 800,000 turnover in the previous year.
- From 1 Jan 2028: e-invoicing is mandatory without exception for all domestic B2B invoices.
Exceptions:
- Invoices to private individuals (B2C) are not covered by the e-invoicing obligation.
- Small amounts: invoices below EUR 250 gross (§ 33 UStDV).
- Small businesses under § 19 UStG are exempt from issuing e-invoices — the obligation to receive them still applies.
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.
Can I read e-invoices I receive in the app?
Yes. In the “Invoices” tab, tap “View a received XML invoice” and pick an XRechnung or ZUGFeRD XML file (CII or UBL). The app shows it as an easy-to-read PDF that you can also share. The file is sent briefly over HTTPS to our server in Germany for this and is not stored there. The view is a reading copy: the original XML is what counts for record-keeping, so keep it. The feature is included in the subscription and the free trial.
Where is my data stored?
Your invoices, clients and bank details are stored on your device (SQLite). To create the PDF, they are sent encrypted to our server in Germany, processed there and deleted within 24 hours at the latest.
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?
For Germany 0%, 7% (reduced) and 19% (standard). Mixed tax rates within one invoice are possible. The app also handles the small-business rule (§ 19 UStG), reverse charge (§ 13b UStG) and intra-community supplies. If your business is based in another European country, the app offers the rates that apply there.
