Billing That Works Quietly So Your Revenue Does Not Stop
We build and connect Apple App Store and Google Play billing into your mobile app, covering every purchase type your product needs. Clients get a stable, auditable revenue layer that handles edge cases before users ever notice them.
Fewer Silent Failures
Server-side receipt validation catches bad transactions before they affect your subscription counts or trigger fraudulent access.
Platform Update Proof
We build to current StoreKit 2 and Play Billing Library APIs so you are not one OS release away from a broken checkout.
Clean Revenue Data
Every purchase event is logged with the platform transaction ID, making reconciliation and refund handling straightforward from day one.
In-App Purchase Integration
The outcome we're after
Most apps lose revenue not because of pricing but because of silent billing failures - expired receipts that are not retried, grace periods that are ignored, and platform updates that break existing purchase flows. These gaps compound quietly until they show up in refund disputes or support queues.
We integrate Apple StoreKit 2 and Google Play Billing Library 6 at the native layer, then wire server-side validation so every transaction is confirmed independently of the device. Our setup covers subscription state machines - including grace periods, billing retry, and paused states - so your backend always reflects what the platform actually charged.
The result is a purchase system that handles real-world conditions: poor connectivity, mid-flow app kills, and account switching. Clients typically see fewer subscription-lapse complaints within the first billing cycle and gain a clear audit trail that simplifies both customer support and revenue recognition.

FAQ
Frequently asked questions
Do you handle both one-time purchases and subscriptions in the same project?
Yes. We configure consumables, non-consumables, and auto-renewable subscriptions within the same integration. Each type follows a distinct flow, and we implement all of them so you are not locked into a single monetisation model now or later.
What happens when a user's subscription payment fails mid-cycle?
Both platforms have a billing grace period during which access should continue while the platform retries the charge. We implement the correct entitlement logic for this window so users are not cut off prematurely, which reduces involuntary churn and support tickets.
Can you validate receipts on our existing backend, or do we need a new server?
We can add validation endpoints to your current backend in Node, Python, or Go, whichever fits your stack. If you do not have a backend yet, we can provision a lightweight validation service as part of the engagement.
How do you test in-app purchases before going live on the App Store or Play Store?
Apple provides a Sandbox environment and StoreKit testing in Xcode; Google offers the Play billing test track with test card accounts. We run structured test scripts across both environments covering happy paths, cancellations, restores, and interrupted transactions before any production release.
