Automated Subscription and Rental Management [closed]

I’m managing game subscriptions and rentals manually and looking for an easier and faster way to handle it. I need a system or tool that can help with:

1- Tracking the start and end dates of each subscription.
2- Storing subscription emails and customer contact info like phone numbers or emails.

How would you recommend I go about this?

I hope to find a more automated solution to simplify and streamline the process
