Is Google Play Leaderboards suitable to rank users of my application according to their in-app purchases?

问题 Users can make in-app purchases in the application of my firm and fix the amount by themselves (I use Google in-app purchases API). They sign-up and sign-in thanks to Google Sign-in API, with and only with their Google Account (no Facebook, no Twitter, etc.). The client asked us to set up a leaderboard. Users who spent the most are first. Users who made cheap purchases are last. The application isn't a game. So it should not be bound to Google Play, in terms, for example, of Android

问题 Google came with with the idea of introductory price (https://support.google.com/googleplay/android-developer/answer/140504?hl=en). My question is related to its API.
