Quick Start

1. Choose payment model — direct payments (Stripe) vs. in-app purchases (App Store/Play Store) based on product type
2. Integrate payment SDK — Stripe Mobile SDK, StoreKit 2, or Google Play Billing Library
3. Implement server-side verification — never trust client-side payment confirmations
4. Handle subscription lifecycle — trials, renewals, cancellations, grace periods, upgrades
5. Add Apple Pay / Google Pay — express checkout for returning customers
