Google Play Billing
What it is
Google Play Billing is a system developers use to sell digital products and content inside Android apps, either as one-time purchases or subscriptions. One-time items can be consumable for repeat purchases or non-consumable for a permanent benefit; they may provide permanent access or a specific non-renewable use. Subscriptions grant defined benefits for a set period and can include base plans, offers, prepaid plans, and add-on entitlements. The Play Billing Library connects an Android app to Google Play Services to retrieve localized offerings and start purchase flows. Google recommends a secure backend for verifying purchases, managing subscription features, and handling real-time notifications. The Google Play Developer API supports purchase and subscription management, status checks, and changes or cancellations to recurring purchases. Cloud Pub/Sub can deliver notifications about changes to Google Play-managed subscriptions. Google recommends verifying purchase tokens on a secure backend before granting entitlements. Unacknowledged purchases are automatically refunded after three days. Billing is for digital items; Google directs sales of physical goods or services to the Google Pay SDK. The listed plan is free.

The verdict
Google Play Billing provides Android developers with purchase flows and tools for managing digital sales and subscriptions. Purchase verification and timely acknowledgment matter, and physical goods and services require a different SDK.
