Rechnungskit for German businesses: every order, e-invoiced

For businesses in Germany: automatic ZUGFeRD e-invoices, GoBD archive, DATEV export.

Built for businesses that sell from Germany and must meet German invoicing rules. Rechnungskit automatically creates a ZUGFeRD e-invoice (EN 16931) for every paid order and archives it in line with GoBD. Cancellations and refunds generate the matching correction documents on their own. VAT is handled correctly case by case, from OSS to exports to gift vouchers. Your tax advisor gets a DATEV-ready export. Once connected, everything runs in the background: no manual invoices, no month-end cleanup.

Automatic e-invoice (ZUGFeRD/XRechnung) for every paid order
GoBD-compliant archive: tamper-proof, kept 8 years, exportable anytime
DATEV-ready export for your tax advisor, accounts already assigned
Correct VAT automatically: OSS, reverse charge, exports, gift vouchers
Stripe, PayPal, Unzer, Klarna & more: fees and payouts booked for DATEV

This app is amazing and fully recommended!

First off, I am an accounting noob but I knew, invoicing, marketplace fees etc. will become an issue if I don't act on it. But before it got there, I got aware of Rechnungskit.

The set up was a breeze. A chat-bot guided me through everything. And while the interface is still a bit overwhelming (well, taxes as an overwhelming topic), Rechnungskit reaches out to you automatically if some input on your end is missing and guides you through the fixes.

Long story short: within literally a few minutes I had my whole invoicing compliantly set up with shopify and all payment channels integrated.
