Payments in your SaaS
Why Stripe is the standard — and how it works.
No SaaS without payments. Whether you want one-time transactions, monthly subscriptions, or a marketplace with splits — Stripe is the go-to solution. In this article we explain why, and what a Stripe integration looks like.
Why Stripe?
All-in-one
Credit cards, iDEAL, Bancontact, SEPA, Apple Pay, Google Pay — one integration for all payment methods.
Subscriptions out-of-the-box
Monthly/yearly plans, trial periods, upgrades, downgrades and cancellations — Stripe handles the full lifecycle.
Security & compliance
PCI DSS Level 1 certified. You never need to store or process credit card numbers.
Developer-first
Excellent documentation, webhooks for real-time events, and SDKs for every programming language.
How does it work technically?
Create a Checkout Session
Your backend creates a Stripe Checkout Session with the product, price and return URL. The customer is redirected to Stripe’s hosted checkout.
Process payment
Stripe handles the payment securely. The customer sees a professional checkout page with all payment options.
Receive webhook
After successful payment, Stripe sends a webhook to your server. Here you activate the account, send a confirmation, or deliver the product.
Pro tip: always use webhooks for processing payments, not the redirect. The redirect can fail (user closes browser), but the webhook is reliable.
Go live with payments quickly
A basic Stripe integration can be set up in a few days. Start with Stripe Checkout for the fastest route to working payments. Expand later with Customer Portal for self-service, and webhooks for automation. It’s the solid foundation under every SaaS revenue model.
