You can sell a VIP Membership to your VIP Lounge thanks to WooCommerce products. In the Products manu, create a new product. The product has to be a virtual product. Enter the price at which you want to sell the VIP Membership like for any other product.
Now go to the WooVIP Membership tab. In the dropdown list, select the VIP Lounge for which Membership will be earned. You can also set a duration period for the membership. If you don’t enter a duration, the VIP Membership will be permanent.
By Default, membership is granted as soon as the order is paid. If you want the membership to be granted only when the order reaches the “Complete” status, go to WooVIP → Settings and check the “Grant membership on complete order only” checkbox.
