FAQ — e-Invoicing obligation and e-Rechnung Inbox
— FAQ —
What people typically ask.
Isn't a PDF also an e-invoice?
No. A regular PDF is the digital photo of a paper — machines can't read it. An e-invoice is structured XML per EN 16931. Only XRechnung and ZUGFeRD (Comfort+) legally count as e-invoices from 2025.
Do I need to forward my existing email?
No. You get a separate address used only for invoices — e.g. yourname@e-rechnung-inbox.de. Your business email stays untouched. Custom domains can be connected today; the route is automated through Mailgun.
We use DATEV. Does this fit?
Yes, directly. We export DATEV CSV and a tax-advisor package ZIP with originals, previews, manifest, booking suggestions and README. Direct DATEV transfer remains beta and production-approval gated.
What about Kleinunternehmer?
Kleinunternehmer must also be able to receive e-invoices from 2025. The receiving mandate applies regardless of revenue or size. You may still send as before.
Can I write invoices with this?
Deliberately no. e-Rechnung Inbox is strictly a receiving and validation system. For outbound, we recommend lexoffice, sevDesk or your existing ERP.
Where is my data stored?
Frankfurt (eu-central-1), EU infrastructure. The hoster operates a certified data center. The DPA template is linked in the footer; process documentation is generated inside the workspace and can be exported there.
