What do you use? Start here.
Store, payment provider, Stripe Billing or your own API: every source runs through the same validated pipeline. Order and payment go in, a compliant e-invoice comes out, ready in DATEV for your tax advisor (Steuerberater).
Shop systems
Order and payment come from your store
Shopify
For Shopify merchants in Germany: Rechnungskit connects your Shopify store with Stripe, Mollie and PayPal. Compliant ZUGFeRD e-invoices from every order, GoBD archive and DATEV export included.
WooCommerce
Rechnungskit connects WooCommerce via the REST API with Stripe, PayPal and Mollie: a ZUGFeRD e-invoice on shipment, cancellation invoices from refunds, a GoBD archive and the DATEV export.
Shopware
Connect Shopware 6 to DATEV without a plugin in your shop: Rechnungskit writes the e-invoice for every order, reconciles payments and fees and delivers the DATEV booking batch with documents.
Payment providers
Every payment becomes an invoice
Stripe
For businesses in Germany: connect Stripe to Rechnungskit and every Stripe payment and subscription automatically becomes a compliant e-invoice (ZUGFeRD), archived under GoBD and ready for DATEV.

Subscriptions and SaaS
Recurring billing, with or without Stripe Billing
Stripe Billing
Connect Stripe Billing to Rechnungskit and every subscription charge automatically becomes a compliant e-invoice with your own number range and service period, archived under GoBD and ready for DATEV, including deferred revenue. Keep Stripe Billing or move the subscriptions over at the end of their period, both through the same connection.
Switching from Stripe Billing
Move running Stripe Billing subscriptions to Rechnungskit: map your prices and switch at the end of the period with the existing payment mandate. Your customers do not have to sign up again.
Subscription checkout
Subscriptions without a store: share a payment link, manage plans and trials, collect through Mollie or Stripe, with an invoice for every charge.
Without a shop
Payment links, your own systems and headless setups
Stripe invoices with payment terms
Send the invoice in Stripe and your customer pays by bank transfer later: the e-invoice is created when you send it, with your customer's Stripe IBAN and automatic payment matching.
Product checkout
One-time sales without a store: a payment link for downloads, licenses and goods, paid through Mollie, Stripe, PayPal or Unzer, with the invoice created automatically after the purchase.
Push API
Send orders from your own system, track their status and fetch the invoices. REST, with an OpenAPI specification.
After the purchase
Unlock access, report purchases to ad accounts
Memberspot
After payment, Rechnungskit automatically gives buyers access in your Memberspot school: one-time purchase or subscription, German e-invoice included, and access removed again on a refund or when the subscription ends.
Ghost
For Ghost publishers in Germany: after payment, Rechnungskit adds the buyer to your Ghost publication as a member with the right tier. One-time purchase or subscription, German e-invoice included, on Ghost(Pro) and self-hosted.
Meta Ads
Rechnungskit reports every checkout purchase server-side to your Meta ad account: a Purchase event with the amount, a Subscribe event when a subscription starts. With a slim consent bar in the checkout, an optional browser pixel, and events that arrive even with ad blockers.
