With YITH Subscription, you can enable recurring payments for the products or services that you sell in your store.
If combined with YITH Multi Vendor, your vendors will be able to sell and edit subscription-based products. It also allows to generate vendor commissions on subscription renewal orders.
To use this feature, just make sure both plugins are installed and activated. Then select Subscription products in the option Vendor can sell, available in YITH > Multi Vendor > Vendors > Vendors permissions.

Now, your vendors will be able to configure the subscription options in their products.
For more details about how to configure a subscription product, please, refer to this page.

Also, the vendor will be able to see a Subscription menu where they can check all subscriptions linked to their products and the subscription activities.
