Manage their subscriptions
When you create a plan (other than one-time payments and subscriptions with a fixed number of payments), you can decide if you want the plan to renew automatically by default. Members can manage their subscriptions from the Subscriptions menu item in their account or by accessing this direct link:

Change plans
If you sell multiple plans, you may want to offer members the option to upgrade / downgrade. When you add all your plans to the same Plan Group, members will have the option to change between them from the Subscriptions menu item in their account.
Apply a coupon during an upgrade
To add a coupon during a plan upgrade, members can navigate to the Subscriptions menu item in their account, click Change plan, and apply the coupon code.
Apply a coupon code to an existing subscription
To add a coupon to an existing subscription, members can navigate to the Subscriptions menu item in their account, click Add coupon, and apply the coupon code.
Renew a subscription that is past due
If a member’s subscription is past due or expired, they can navigate to the Subscriptions menu item and click Renew Now. Next, they can update their payment method (if required) and renew their subscription.
