Is the app required to have in-app subscription model if we already have our own infrastructure (account management and payment) via web portal and an existing web solution for our target audiences?

The target audiences are employees of a network of distinct partner organizations. Partner org purchases subcription for their target employees to use the app. The app will require an account to login, which is provided after partner pays for users' subscription. With that being said, there's no public signup.


Our team already has our own infrastructure (account management and payment system) via web portal and an existing web solution for our target audiences before this.


- Is the app still required to have in-app subscription model, based on what I've described above?
