The Sharpei Subscriptions app is the plugin designed by Sharpei which will sync directly with your Shopify account. With it you'll be able to create and configure subscription plans for your products called Selling Plans, which will be inside a Selling Plan Group.
After you create your Selling Plans, you'll be able to add them to all the products you want.
Selling Plans Groups are composed by the Selling Plans you create.
With a Selling Plan Group you'll be able to create multiple Selling Plans associated to it, which can have different different rules for your subscription. These are added to the products you choose.
Therefore, Selling Plans are the subscription options you can configure and that will be displayed to the customer in the product page and checkout.
In a Selling Plan you can set up and configure the delivery, billing and pricing policies.
The data you configure in the Selling Plans will be the one the customers see.
Delivery Policy: Set up delivery intervals; the frequency in which you want the products to be shipped during the subscription, e.g send product every 4 months.
You can also choose the type of delivery between fixed and recurring.
Billing Policy: Set up billing intervals, meaning the frequency in which you want to bill your customers.
Also, in the billing policy you'll be able to set up the minimum and maximum number of payments for a subscription period.
The billing policy needs to match the delivery policy.
Pricing Policy: Add a discount percentage on the product price for a subscription period.
Quantity Policy: Sets the lowest number of units a customer must purchase for a particular product in a subscription.
