Google is now launching a new pilot to test third-party billing systems in Android and across their wider ecosystem as the company just announced on Wednesday that they plan to conduct the pilot with a handful of participating developers, starting with Spotify. Later this year, Spotify users that downloaded the app through the Play Store will be able to pay for a subscription through either Google’s or Spotify’s billing systems for the first time.

The two options will be kept side by side as the user will be given the freedom to subscribe and make purchases through the payment gateway of their choice directly inside of the app. Spotify says that they are going to be collaborating with Google on that functionality within the coming months and with the work involving product and engineering teams across both of the companies.

For Spotify, this is a very big breakthrough victory, as the company has already spent a lot of years campaigning against these monopolies the app stores have. For Google, this pilot is very much a very defensive move, as just like Apple, the company has spent significant time and resources going against legislation like the Open App Markets Act, which was recently advanced by the Senate Judiciary Committee.
