Recurring revenue
that survives a cancelled card and a platform audit
A subscription looks simple from the user's side: tap to subscribe, get access. From the backend's side, it's a surprising amount of edge cases. A renewal can fail silently. A refund should revoke access. A grace period means a lapsed card shouldn't immediately lock someone out. We build the entitlement logic around what actually happens to a real subscriber's billing over a year, not just the happy path of a successful first purchase.
What it is
In-app subscription infrastructure covers everything between a user tapping “subscribe” and your backend correctly knowing whether that user should still have access. That has to hold at every point over the following months, not just at the start. That means product configuration in App Store Connect and Google Play Console, and server-side validation of the purchase. It also means entitlement logic that correctly handles renewal, cancellation, refund, grace periods and billing retries. Not just the first successful charge.
When you need this (and when you don’t)
It earns its cost for any app selling recurring access to content or features through the App Store or Google Play. Both platforms require this for digital goods consumed inside the app itself. A fitness app with premium coaching tiers, and an AI persona product with subscription access behind its content, both needed this infrastructure built correctly from the start. A subscription system that gets entitlements wrong either leaks paid content for free, or locks out paying users on a temporary billing hiccup. Both failure modes cost real revenue and trust.
It’s the wrong tool if your product is sold once outright with no recurring billing. A one-time in-app purchase is a simpler flow that needs less of this. And if your subscription is actually billed and managed entirely on the web, outside the app, you may not need platform billing integration at all. That depends on what each platform’s current rules allow for your specific content type, and we check this with you before building anything.
How we build it
Subscription products get configured correctly in App Store Connect and Google Play Console first: pricing tiers, trial periods, promotional offers. Mistakes here are hard to correct once real subscribers exist on a product. The client requests a purchase through StoreKit on iOS, or the Play Billing Library on Android. The resulting receipt or purchase token is never trusted on its own. We send it to our backend, which validates it directly against Apple’s or Google’s verification endpoint before granting any access.
Entitlement logic is built around what actually happens to a subscription over its lifetime, not just a successful first charge. A renewal that fails temporarily enters the grace period and billing retry window both platforms define. Access should typically continue while the platform retries the charge, rather than getting cut immediately. Both App Store and Google Play send server-to-server notifications for events like cancellation, refund and chargeback. We treat these as the authoritative source for revoking access, instead of relying on the app happening to check status again at the right moment.
The paywall and upgrade flow get built around your actual pricing tiers, and around the specific point in your product where a user should see the offer. A restore purchases flow covers anyone reinstalling the app or switching devices. A user who already paid and loses access on a new phone is both a support ticket and a trust problem. Analytics track conversion and churn with enough detail to see where in the flow users actually drop off, not just the final subscribe-or-not number.
What to watch
App Store and Google Play subscription policies change periodically: trial periods, win-back offers, required disclosures. Entitlement logic needs occasional review against current platform rules, not just a one-time build.
Receipt validation needs real server infrastructure, not a shortcut. Done wrong, it either leaks free access or wrongly revokes a paying customer’s. Both are expensive mistakes to discover after launch rather than catch in testing. Running subscriptions on both platforms plus a web option also multiplies the entitlement states that need handling correctly. We test the actual cross-platform access logic explicitly, rather than assuming each platform’s flow in isolation covers the real combined case.
Price and timeline
| Option | Price | What it covers | Timeline |
|---|---|---|---|
| Single platform, core flow | from $2,500 | Product setup, validation, entitlement logic, paywall | 2 to 3 weeks |
| Both platforms, full lifecycle | from $5,500 | iOS and Android, grace periods, refunds, analytics | 3 to 4 weeks |
Running cost is the platform’s standard commission on subscription revenue. There’s no separate infrastructure fee beyond your own backend hosting.
What this pairs with
This pairs with customer portal and personal account for where a subscriber manages their plan, and with push notifications infrastructure for renewal reminders and win-back messaging. See the development service page for our full build process. For real examples, see the fitness app’s coaching subscription tiers and the AI persona business’s subscription product.

FAQ
How much does in-app subscription setup cost?
From $2,500 for subscription products on one or both platforms, with server-side validation and core entitlement logic, in 2 to 4 weeks. A system with multiple tiers, promotional offers and detailed churn analytics runs $4,500 to $8,000.
Why can't the app just check the subscription status itself?
A purchase receipt or token checked only on the client can be faked, replayed, or simply never checked again after the first successful purchase. That's how apps end up giving away content to lapsed or fraudulent subscriptions. We validate every entitlement server-side against Apple's or Google's own verification endpoint. The client's claim is a request to check, never the answer itself.
What happens when a renewal payment fails?
Both platforms have a grace period and a billing retry window before fully lapsing a subscription. We build the entitlement logic to respect that window, instead of cutting access the instant one payment attempt fails. A temporarily declined card is extremely common and shouldn't read as a cancellation.
Do you handle refunds and chargebacks?
Yes, through the server-to-server notifications both App Store and Google Play send when a refund or chargeback happens. We use those to revoke access automatically, instead of relying on anyone noticing manually.
Does this work with web-based subscriptions too?
We can run App Store and Google Play subscriptions alongside a web-based Stripe subscription for the same product. The entitlement logic treats all three as inputs to one unified access check, so a user's access is correct no matter which platform they actually paid through.
