The three things invoicing software gets wrong

The e-invoicing mandate, VAT, and the question of where your data actually lives.

E-invoicing mandate

XRechnung and ZUGFeRD without the accountant drama

Since 2025 every German business must be able to receive e-invoices, and anyone billing public authorities has to send them too. Rechnio produces both formats straight from the finished invoice — validated against EN 16931 before anything leaves the device.

  • XRechnung as a pure XML file for authorities and large clients
  • ZUGFeRD as PDF/A-3: looks like it always did, carries the data machine-readably
  • Mandatory fields checked before export — routing ID, VAT ID, payment terms
  • Read incoming e-invoices and book them as an expense

Tax & reporting

The VAT works itself out

Every paid invoice and every scanned receipt feeds the reports. Rechnio shows profit, VAT collected and input tax per month or quarter — and hands over the figures in the exact format ELSTER expects.

  • Boxes 81, 86, 66 and 83 in the exact form layout, ready to type in
  • Cash and accrual accounting, small-business rule per § 19 UStG
  • GoBD package as a ZIP: invoice PDFs, receipt photos, CSV and DATEV journal
  • 12-month history for revenue, income and expenses

  • No login, no sign-up, no email address required
  • No tracking, no analytics SDKs, no advertising IDs
  • Text recognition and quick capture run entirely on device
  • Full backup as a file — your data stays exportable

Three steps to your first invoice

From download to a sent PDF takes less than ten minutes.

1

Set up your company profile

Name, address, tax number, bank details and logo — fill it in once and it appears on every document.

2

Pick a customer and line items

Import customers from Contacts, save services as items. Next time it's two taps.

3

Check, export, done

Rechnio validates the mandatory fields, produces PDF, ZUGFeRD or XRechnung and opens the email with the attachment.

Your data stays your data.

Rechnio stores everything locally and syncs only through your private iCloud. We run no servers and never see your invoices.

Frequently asked questions

What freelancers most often want to know before switching.

Does the e-invoicing mandate apply to me?

If you invoice other businesses in Germany: yes. Since 1 January 2025 every company must be able to receive and process e-invoices; the obligation to send them phases in through 2028. Anyone supplying public authorities already has to send XRechnung today. Rechnio handles both directions.

Do I need an account or a sign-up?

No. Download the app, fill in your company profile and write the first invoice. There is no login, because there is no server to log into.

What happens to my data?

It stays on your device. Turn on iCloud sync and it additionally sits in your private iCloud — not with us. We have no technical access to your invoices.

Can I use Rechnio on iPhone, iPad and Mac?

Yes, on all your devices with one subscription. iCloud keeps customers, items and documents in sync everywhere.

Does Rechnio replace my tax adviser?

No — it supplies them with data. The GoBD package contains every invoice PDF, receipt photos and a CSV and DATEV journal per period. The VAT return you can file yourself using the guided ELSTER walkthrough.

Can I take my data with me?

Any time. Full backup as a file, PDF export for individual documents, CSV and DATEV for bookkeeping. There is no lock-in — not even if you end the subscription.
