Deep SaaS billing tutorial
Stripe Subscription Setup Guide
Stripe subscriptions are more than a checkout button. A SaaS billing system needs products, recurring prices, checkout sessions, webhook handling, customer records, access rules, and a tested customer portal path.
Billing model
Start with products, prices, and access rules.
Before writing code, decide what customers buy and what access each plan unlocks. Stripe products and recurring prices should map to simple application rules.
Create one product for the SaaS or one product per major offering.
Create recurring monthly and annual prices for each tier you plan to sell.
Store Stripe price IDs in environment variables.
Map each price ID to a plan name and access level in your app.
Implementation
Build the subscription flow in order.
Most billing bugs come from skipping lifecycle steps. Implement checkout, return states, webhook persistence, access rules, and customer portal as one connected flow.
Step 1
Create checkout sessions
Use the selected price ID, authenticated user, success URL, cancel URL, and metadata that lets you connect checkout back to the app account.
Step 2
Listen for checkout completion
Use webhook events to connect the Stripe customer and subscription to your user after payment succeeds.
Step 3
Persist subscription state
Store customer ID, subscription ID, plan, status, current period dates, and cancellation state if your app needs them.
Step 4
Gate paid features
Use the mirrored subscription state to decide whether the user can access paid routes, limits, or team features.
Step 5
Open the customer portal
Let customers update payment methods, view invoices, manage subscriptions, or cancel without support tickets.
Step 6
Test every lifecycle path
Test success, cancel, upgrade, downgrade, renewal, failed payment, cancellation, and webhook retry behavior before launch.
Webhook events
Handle asynchronous changes carefully.
A customer can change billing state outside your app. Webhooks keep the application current when invoices, subscriptions, and checkout sessions change.

FAQ
Answers for founders comparing the next step.
How do I set up Stripe subscriptions for SaaS?
Create products and recurring prices in Stripe, create checkout sessions from your app, listen for subscription webhooks, store subscription state, gate paid features, and enable the customer portal.
Which Stripe webhooks should a SaaS handle?
Common SaaS webhooks include checkout.session.completed, customer.subscription.created, customer.subscription.updated, customer.subscription.deleted, invoice.paid, and invoice.payment_failed.
Should my app trust checkout redirects or webhooks?
Use redirects for user experience, but use webhooks to persist billing state because subscription and invoice events can happen asynchronously.
