This week Google had its Google I/O conference. A number of announcements were made about in-app purchases (IAPs), subscriptions, the Google Play Store, and the Google Play Billing Library.
We’ve found all the major announcements related to selling digital products with your apps on the Google Play Store so you don’t have to go watch all the talks.
Google Play Billing v4
The single biggest announcement for in-app purchases and subscriptions is the release of v4 of the Google Play Billing Library. Release notes for Play Billing v4 can be found here. While the library is available immediately, the new capabilities it provides have not been released yet and details are pretty scarce on exactly how all the features work.
We’ll continue to updated this blog as more information is released on these exciting new ways to sell products on Google Play.
Multiline Subscriptions
Coming later this year, Google teased how you can bundle together multiple different subscription products and sell them as a single purchase.
Currently, if you want to bundle up multiple subscriptions in your app, you have to create a new subscription product in the Play Console. You might call it Bundled Subscription, set a price, and then internally in your app grant the correct access to the content and features unlocked by the set of subscriptions that were accessed via the purchase. This logic all has to be created in your app code.
This new approach potentially offers some advantages over the old method of selling bundles:
The customer can see a line item breakdown of each subscription they are purchasing.
Presumably, Play Billing will grant purchases on each included subscription, simplifying your in-app logic for granting access to paid content and features.
Hopefully, Google will offer a mechanism to offer a bundled purchase discount, though they did not show that capability in their talks.
Multi-Quantity Purchases
Another exciting announcement is the support of multi-quantity purchases. This enables Play Billing to work in a manner similar to a shopping cart. For one-time purchases, customers will be able to add multiple quantities of an item during the checkout process and buy them with a single purchase.
Prepaid Plans
Google also announced Prepaid Plans. These will allow you to sell access to content or features for a fixed period of time. Google will prompt the customer to renew for more time as their prepaid plans expire, but there are no details yet on how that will work.
As announced at Google I/O last year, each major version of the Google Play Billing Library will be supported for 2 years. Google is officially sunsetting AIDL for in-app purchases as well as Play Billing Library versions 1 and 2 this year.
All new apps must use version 3 or 4 of the Play Billing Library by August 2, 2021. All existing apps must switch by November 1, 2021.

Comparative Revenue Metrics
Google started rolling these out earlier this year. 15 new metrics covering both engagement and monetization of your app have been added to the Play Console. The most interesting part is that they’ve created comparative benchmarks to help you understand how well your app is performing versus similar apps. This can help you quickly see where you might need to spend effort on improving your monetization efforts.
Google has created over 250 categories of apps and games to help you find your correct peer set. They have excluded small, underperforming, and abandoned apps to improve the accuracy of the benchmark reporting.
In the Play Console, select your app, click on Statistics in the left navigation, and then click the Compare to peers tab. You can then click on the Metric Name, select Monetization, and see the list of metrics available.
You can also click on the Peer group to limit the comparison to specific categories of apps. Clicking on the Country / region will allow you to further filter by location.
Lower Priced IAPs in Some Markets
In many markets around the world, Google is introducing sub-US dollar pricing. This will help you better market your app in places where the current price points do not align with the spending power in the local market. A full list of price points and countries is not available yet, but Google did share which countries will be getting new price points for IAPs on the map below.
Play Billing and Progressive Web Apps
Play Billing support for Progressive Web Apps (PWAs) was launched earlier this year. You can now integrate Play Billing into a PWA and sell in-app purchases and subscriptions on Chrome OS.
Purchases made with Play Billing will be shared between Chrome OS and Android, which is very exciting. Integrating Play Billing with a PWA requires using 2 APIs, the Digital Goods API and the Payments Request API. See Google’s documentation on how to use both these APIs to enable purchases in PWAs.
Google has also provided an example app to show how this all works.
