About this Gig
Do you need Google Play Billing, subscriptions, in-app purchases added to your native Android app?
I will integrate, upgrade, or repair Google Play Billing in Kotlin using a lifecycle-safe, maintainable, and Play Store-compliant implementation.
I can help with:
- Consumable and non-consumable purchases
- Monthly and yearly subscriptions
- Free trials and introductory offers
- Remove Ads and Premium Unlock
- Billing Library migration
- Pending or failed purchases
- Purchase acknowledgement
- Restore purchases
- Subscription status and entitlement handling
- Billing errors and Play Console warnings
Example solutions include fixing purchases that complete but do not unlock premium features, restoring purchases after reinstall, preventing unacknowledged purchases from being refunded, and upgrading outdated Billing Library implementations.
You will receive clean source-code changes, testing notes, and an explanation of the implemented purchase flow.
Backend purchase verification, RevenueCat integration, multiple subscriptions, and account-based entitlements can be provided through a custom offer.
Please message me before ordering for complex or existing broken billing systems.

FAQ
1. Can you add a Remove Ads purchase?
Yes. I can add a non-consumable Remove Ads purchase and connect it with your existing AdMob implementation.
2. Can you integrate subscriptions?
Yes. I can integrate monthly or yearly subscriptions, including base plans, offers, purchase handling, and entitlement checks.
3. Can you update an old Billing Library?
Yes. I can review and migrate an older Google Play Billing implementation while preserving existing app functionality.
4. Do you support Kotlin and Java apps?
Yes. I support native Android applications developed with Kotlin or Java, including Jetpack Compose and XML interfaces.
5. Can you fix purchases that are not restoring?
Yes. I can investigate purchase querying, acknowledgement, entitlement persistence, account handling, and restore-purchase logic.
6. Do you test purchases before delivery?
Yes. Testing can be performed using Google Play license testers and internal testing. Your app and products must be correctly configured in Play Console.
7. Do you provide backend purchase verification?
Backend verification is available through a custom offer because its scope depends on your server, authentication system, database, and entitlement model.
8. Do you need my Google account password?
No. Never send your password. When Play Console configuration is required, you can provide appropriate temporary user permissions.
9. What do you need from me to integrate Google Play Billing successfully?
Please provide your Android Studio project source code, package name, Billing Library version, product IDs, subscription IDs, and details of the required purchase flow. If products are not configured, temporary Play Console user access may be required
Do I need to create the products in Google Play Console first?
Not necessarily. I can guide you through product creation or configure in-app products and subscriptions when Play Console setup is included in the package or custom offer. The app must be uploaded to an internal testing track before real Google Play Billing tests can be completed.
