In-App Purchases and Subscriptions

This package adds in-app purchases and subscriptions to your Flutter or React Native app through Apple's and Google's own billing, and makes sure the right users get access, keep it on renewal and lose it after a refund. It suits apps that sell premium features, content or ad-free use, where the store rules say payment has to go through the store.

Which sales must use store billing

As a general rule, digital features or content used inside the app go through StoreKit on iOS and Google Play Billing on Android, while physical goods and real-world services use a normal processor such as Stripe. Apple and Google keep a commission on each store sale, at a rate set by their programs and your revenue, so build it into your prices. Rules on pointing users to a web checkout differ by country and have changed recently, so I check the current guideline for your markets during scoping instead of assuming.

How access is checked

Starter uses RevenueCat to validate receipts and hold entitlements, the quickest route for a few products. Business verifies every purchase on your own server, through the App Store Server API and the Google Play Developer API or RevenueCat webhooks, and stores access against the user's account so it follows them to a new phone. Premium listens to Apple's server notifications and Google's real-time developer notifications for renewals, billing retries, grace periods and refunds, applies the same access on iOS, Android and your web app, and gives your team an admin view of who pays for what.

Your part in the stores

The Paid Apps agreement with its banking and tax forms in App Store Connect, and the payments profile in Google Play Console, must be completed by you as the account holder before anything can be sold. RevenueCat is free up to a revenue threshold and then charges a share of revenue, billed to you. Testing runs in Apple's sandbox and with Google's license testers, so nobody is charged while every path is checked, including restore purchases on a fresh install.
