Cross Platform Monetization & Update solution?

i am creating a non game application and i desperately search for a solution to monetize my application. it will be at least on windows and android and i want to sell content/features with a unified account so that users can switch their devices and still use the same account and content.

another nice to have feature would be to handle all updates of the application and content… just like all games do ^^ i didn’t know that there does not seem to be any out of the box solution for non game apps…

so does anybody know a solution that can do that for me? or at least parts of it? if i have to buy ten different plugins to achieve that so be it, i really want to avoid to write all that myself.

thanks for reading ^^
