YITH WooCommerce Subscription is a plugin designed to enable recurring payments for the services offered in your shop.
The integration between the two plugins will allow your users to purchase a subscription for several services, meaning, for instance, a subscription-based product with a custom set of selected add-ons.

You will only have to activate both plugins, in order to make them work together. After that, you can create your subscription product as usual, and add your add-ons from YITH > Product Add-ons. For more information on how to create a Subscription, check the documentation here.

The recurring price of the subscription will be the regular price + add-on price, so, considering the above screenshot, it will be €25.00 a week, as the “Home delivery” extra option that costs +€5.00 has been selected.
