Logged-in users who have made a purchase on the site will have the opportunity to open a support ticket.
WooCommerce, however, also allows guest users to purchase, without the need to register, which is why the plugin allows you to enable the service even in these cases.
Once this option is enabled, the guest user can access the support service simply by filling out the form shown in the image below, providing his name, email address and the number of the order placed on the site.
The style of the form, as well as that of the other graphics, will depend on the WordPress theme in use.
