Seeking advice on releasing a project with a subscription service

Hi all,
I have a project that I am looking to release soon with a monthly subscription model. It’s a non-game application. I’m looking at starting the project on PC/Mac and later migrating to mobile platforms. I’m just starting to gather information on how to do this…what services or platforms are available to release a project in this way? Any advice would be appreciated.

Thank you in advance
Travis
