Managing subscriptions
After you install the Shopify Subscriptions app, and set up subscription plans, your customers can make scheduled purchases on a recurring basis. You can manage all of your subscription plans and contracts within the Shopify Subscriptions app, and then display your subscription plans on your online store. The Shopify Subscriptions app also adds a new subscription policy and subscription email notifications to your store.
After you set up Shopify Subscriptions for your store, and create subscription plans for your products, you might need to modify subscription plans or contracts, update customer details, or adjust upcoming orders.
