From zero to shipped Put the pieces together in order. Each step assumes the previous one works. 1. Decide your routes per market: US (Route A or B), EU (Route C or B), Android (Route D or B), and the fallback where nothing better is allowed. 2. Stand up web checkout: choose Stripe or a Merchant of Record, define your plans, and wire the billing portal. 3. Build the entitlement server: webhook handler, entitlement store, and a signed entitlement check the app can call after login. 4. Wire the web-to-app handoff: account-first login, plus a deep link or magic link back into a signed-in state. 5. Add the store integrations: Apple's External Purchase Link entitlement and disclosure sheet for US; the reader entitlement if you qualify; Google's external offers enrollment and API for Android; EU storefront flow. 6. Handle the lifecycle: dunning, refunds that revoke entitlement, plan changes, and cancellation. 7. Test the unhappy paths: failed renewal, refund, chargeback, login on a new device, and a user who bought on web but opens the app first. Ship the smallest version that collects money on the web and grants access in the app; everything else is optimization. Educational material, not legal or tax advice. App-store rules and the underlying court cases are changing month to month in 2026 — always confirm the current terms in Apple's and Google's own developer documentation before you ship, and get professional advice for your jurisdiction.
