The Google Play Billing Library simplifies the development process for billing, allowing you to focus your efforts on implementing logic specific to your app. It provides a straightforward and simple interface for sending in-app billing requests and managing in-app billing transactions, and saves you integration time when new features are launched.

Verify purchases and manage your subscriptions with the Play Developer API. You can query subscription status, defer billing, execute refunds, and get subscription updates with real-time developer notifications.

Conveniently and securely test real purchases and purchase flows in your app during development or in preparation for launch without incurring actual charges.

Google Play supports over 135 countries to buy and sell digital goods, which means you can sell to a global audience without collecting separate payment information or looking into regulations in each country.

Customers can pay with credit or debit cards, via 150+ direct carrier billing partners in 50+ countries, with gift cards bought from 700K+ locations in 30+ countries, and with Paypal in 20+ countries.

Our design and engineering teams carefully test and optimize the buying process to make purchases fast and easy, so buyers can pay the way they want.

Users get the benefit of a familiar and trusted payment method. Google protects users' payment info with multiple layers of security, using one of the world’s most advanced security infrastructures.

Use free trials or introductory pricing to attract subscribers, or distribute promo codes to give in-app features away to a limited audience free of charge. Both allow you to creatively engage with potential customers to drive trial and conversion in your apps and games.
