Stripe billing integration (DACH)
SaaS providers who want to bill recurring revenue reliably and in line with DACH requirements.
Updated: 2026-09
This package builds your SaaS subscription billing on Stripe reliably: plans, trials, dunning for failed payments, VAT handling and Swiss QR invoices — with idempotent webhook processing. The result is billing that does not lose revenue to technical detail and that fits the DACH market.
Billing looks simple and is not: failed payments, expired cards, VAT treatment, refunds, and webhooks arriving twice. Each of those points can silently lose revenue or disrupt the accounts.
A clean Stripe integration handles exactly those cases — with idempotent processing, considered dunning, and VAT and QR-invoice handling that fits the DACH market.

FAQ
Does this cover Swiss VAT and QR invoicing?
Yes — the DACH specifics are the core of this package, including the Swiss QR invoice.
What happens with failed payments?
Considered dunning recovers a large share of them automatically — revenue that would otherwise be lost silently.
Why does idempotency matter?
Because webhooks can arrive more than once. Without idempotent processing, actions such as invoices or emails would fire twice.
