FAQ

Common Questions

Quick answers about this service

Do I have to use Google Play Billing for all payments?

For digital goods and subscriptions within Android apps, yes — Google Play's policy requires using their billing system. Physical goods, services rendered outside the app, and certain content types may be exempt. We advise on what applies to your specific case.

What is server-side verification and why do I need it?

Server-side verification checks purchase receipts with Google's servers to confirm they're legitimate. Without it, users can fake purchases using modified APKs or receipt manipulation tools. It's essential for any app with premium features.

How do RTDN (Real-time Developer Notifications) work?

Google sends subscription-state events through Pub/Sub for renewals, cancellations, pauses, and payment issues. Your backend validates the affected purchase and updates access without relying on a slow polling schedule.

Can you help with existing billing code that's broken?

Yes. We trace the client purchase flow, acknowledgment, backend verification, product configuration, and notification handling, then repair the smallest responsible part of the implementation. We also migrate apps away from older or unsupported Billing Library releases.

What about Apple's App Store billing?

For cross-platform apps using Flutter or React Native, we can implement unified billing that works with both Google Play Billing and Apple StoreKit. Contact us for a custom quote.

What are Google Play Billing Library requirements?

We need the app source code, Play Console access with appropriate permissions, the product or subscription catalog, backend and Google Cloud access when server verification or RTDN is included, and license-tester accounts. We confirm the currently required Billing Library release during the technical review.

How does a Google Play Billing Library migration work?

We inventory the current billing code and dependencies, map deprecated calls to supported APIs, update purchase and acknowledgment handling, test upgrades and renewals, and prepare a release that meets the Play Console deadline shown for your app.

Which Google Play Billing Library version should my app use?

Use a release that Google currently accepts for new submissions and updates, while also matching your Android stack and third-party billing dependencies. Because enforcement dates change, we verify the Play Console notice and official release notes at project kickoff instead of hard-coding a version into the plan.

How does Google Play payment policy affect digital goods?

Digital content, app features, and subscriptions sold inside a Play-distributed Android app generally require Google Play Billing unless a documented exception or eligible program applies. We review the product and target markets against the current policy before designing the payment flow.
