Stripe is what you reach for when payments are not just a button.
Once billing state changes what a user can access, payments become part of your product architecture. That means checkout, subscriptions, invoices, failed payments, refunds, customer portals, taxes, and webhooks all need to agree with your app.
Why Stripe is still Matt’s Pick
For the Add Payments job, Stripe is the strongest long-term default because it rarely runs out of room.
You can start with hosted Checkout and still grow into:
- recurring subscriptions
- usage-based billing
- invoices and quotes
- customer portal flows
- fraud screening
- tax calculation
- more complicated pricing experiments later
That flexibility is the point.
Where Stripe asks more from you
Stripe gives you powerful primitives. It does not remove the need to design billing behavior.
The dangerous parts are usually not the first successful payment. They are the second-order states:
- renewal failed
- subscription canceled
- payment method updated
- customer upgraded mid-cycle
- webhook arrived twice
- webhook arrived late
If your AI coding agent only wires up the happy path, Stripe can look done while your app is quietly lying about who has access.
When I would pick something else
If you are selling a simple software product and want tax/merchant-of-record handling bundled, Lemon Squeezy or Polar may be a calmer first move.
But if you are building a SaaS app and expect billing to grow with the product, Stripe is still the grown-up answer.
