Subscription Module

We need to develop a robust subscription module to enable sites to handle various subscription types. The module should offer the following features:

Key Features:

1. Subscription to Content Items:

   • Allow users to subscribe to individual content items. For instance, you can create a content type called Member and enable users to purchase a subscription to a Member item.

2. Subscription to Sites:

   • Provide a mechanism for subscribing to a site. For example, you can create a content type named SitePlan, which users can subscribe to. Additionally, the SitePlan should automatically generate a tenant upon subscription.

3. Multiple Payment Providers:

   • Implement support for multiple payment providers to offer flexibility in payment processing.

4. Stripe Integration:

   • Integrate with Stripe to support seamless online payments.

5. Pay-Later Option:

   • Add a "pay-later" payment provider for handling offline payment processing.

6. Admin UI for Subscription Management:

   • Develop an intuitive admin interface for managing subscriptions, including viewing and modifying subscription details.

7. Admin Dashboard Widgets:

   • Create widgets for the admin dashboard to display key subscription metrics, such as:
     • Total number of subscribers
     • Monthly revenue

8. User Subscription Management:

   • Enable subscribers to manage their own subscriptions, including:
     • Changing subscription levels
     • Canceling subscriptions
     • Updating payment methods
     • Viewing payment history and printing receipts
