Play Store Solutions implements or repairs Google Play Billing for your Android app. IAP Setup starts at $299 for the client purchase flow; Subscriptions adds server-side verification at $599; Complete adds Real-time Developer Notifications at $999. We confirm the app, backend, and test scope before work begins.

This service is designed for
The selected tier and written proposal determine which deliverables are included
Integration or migration to the Play Billing Library version required for the release, using supported product APIs and purchase flows.
Scoped subscription setup for agreed tiers, trials, offers, grace periods, account hold, replacement behavior, and entitlement rules.
One-time and consumable in-app purchases with proper acknowledgment flow, purchase state tracking, and refund handling.
Included in Subscriptions and Complete: backend purchase checks through Google Play Developer API, with entitlement rules and replay-safe processing. The $299 client-integration package does not add a verification backend.
Included in Complete: Google Cloud Pub/Sub notifications trigger a purchase-state check and idempotent entitlement update. RTDN setup is not included in the $599 Subscriptions package.
Scoped event and reporting setup for agreed measures such as active entitlements, renewal states, offer uptake, and cohort analysis; business outcomes depend on product and market behavior.
Written deliverables, third-party costs, exclusions, and remedies before payment
Choose the package by the work your app still needs. A client-only integration does not replace production purchase verification: retain a suitable existing backend or scope one before release. New server verification is included in Subscriptions and Complete; RTDN setup is included in Complete. Cloud charges, third-party platform fees, and ongoing maintenance are separate from implementation.
Client purchase flow; no new verification backend
Scoped subscription implementation
IAP + subscriptions + RTDN
From scoped intake to delivery
We map the digital or physical product, entitlement, audience, distribution, and target markets to the current requirements, then document the tradeoffs of subscriptions, one-time products, or a scoped hybrid.
Map products to entitlements and identify the existing backend or managed platform. New server verification is scoped in Subscriptions or Complete; RTDN setup belongs to Complete.
Client purchase integration is included in every plan. Subscriptions and Complete add server-side verification; Complete adds RTDN. We record which existing systems remain your team's responsibility.
Use license testers and the agreed test environment to record purchase, recovery, and failure cases. A client-only package tests the client flow; backend and notification acceptance requires the relevant systems and scope.
For each agreed test, record the build, product or base plan, starting entitlement, action, observed result, and remaining defect. Use license-test accounts. Backend and notification cases require those systems in scope or an existing integration your team can test.
The record names the authoritative systems and explains how client, backend, Play APIs, and Pub/Sub exchange identifiers and state.
Every product or base plan maps to a user benefit and an explicit server-side access rule.
Known limitations and failed cases remain visible instead of disappearing behind a successful happy-path purchase.
| Test to perform | Expected state | Record before sign-off | If it fails |
|---|---|---|---|
| Start a pending test purchase, then complete or cancel it | No entitlement while PENDING; grant only after verified PURCHASED | Starting access, pending state, final state, and whether access changed | Hold the release if a pending or cancelled payment grants access |
| Verified purchase | Grant the agreed benefit, then acknowledge or consume as required | License-tester record plus backend audit event | Repeated processing must not grant the benefit twice |
| Renewal or expiry | Entitlement follows current purchase state and configured grace/account-hold rules | API response, scheduled reconciliation, and state transition | Retry safely and surface stale-state alerts |
| Upgrade, downgrade, or replacement | Old and new products follow the selected replacement behavior | Plan-change cases with effective-date assertions | Hold release when proration or access outcome is unclear |
| Subscription cancellation | Renewal stops; access normally continues until the verified expiry | Cancellation and expiry tested as separate transitions | Do not treat cancellation as immediate revocation |
| Refund or revocation | Access follows the authoritative purchase state and the action taken | API recheck, notification when available, and idempotent audit trail | Reconcile missed, duplicate, or delayed events |
| Restart the app after payment but before the client receives the result | Purchase recovery reconciles the verified purchase with the correct user entitlement | App restart, purchase re-query, backend result where in scope, and final access | Do not ask the user to buy again before checking the existing purchase |
| Replay an RTDN message or deliver a stale event after a newer one | The handler queries current purchase state and applies the entitlement idempotently | Message ID, purchase-state lookup, processing outcome, and unchanged grant count on replay | Do not grant from the notification alone or let an old event overwrite newer verified state |
Platform requirements change. We recheck these first-party pages and the notice shown in the client's own console before finalizing scope.
First-party entry point for current Billing Library concepts, lifecycle, requirements, and release guidance.
Client connection, product query, purchase processing, acknowledgment, and error-handling guidance.
Defense-in-depth guidance used to scope backend verification without claiming that one control prevents fraud.
Base plans, offers, lifecycle, plan changes, and subscription-specific implementation guidance.
Notification types and the verification/reconciliation behavior required after an event arrives.
License testers, test tracks, payment methods, and lifecycle test guidance used for the release matrix.
A reliable purchase flow includes product configuration, server verification, lifecycle handling, and recovery paths.
| Option | Best for | Ownership | Delivery | Trade-off |
|---|---|---|---|---|
| Client-side prototype | Early validation with test products | App team controls local UI and test setup | Basic purchase launch and local handling | Insufficient for durable production entitlements |
| Production billing setup | A defined catalog needing verified entitlement state | Client owns Play Console products and backend | Client integration; server verification in Subscriptions/Complete; RTDN in Complete | The quote must name the backend, tests, and operational owner |
| Subscription or entitlement migration | Existing users, legacy SKUs, or backend changes | Shared product, data, and engineering decisions | State mapping, migration plan, reconciliation, rollback criteria | Higher risk and discovery than a new integration |
From Play Console products to backend verification, each decision is mapped to an explicit purchase and entitlement state with a testable fallback.
We implement the product query, purchase flow, acknowledgment, error handling, restoration, and test setup for the supported Android billing stack.
Our Google Play in-app purchase setup service covers one-time products and consumables. Subscription work adds base plans, offers, trials, upgrades, downgrades, grace periods, and account hold.
Server-side purchase checks, RTDN event handling, reconciliation, and migrations from older Billing Library code help keep entitlement state aligned with the verified Google Play record.
