Every time a new visitor places an order in your X-Cart store, their name and information appear on your store's user list. You can see and manage all your customers in the user list in your store's Admin admin.
X-Cart 5.4.x - Users > Users List
X-Cart 5.5.x - Store Management > Users
NOTE: In X-Cart 5.5, a store administrator can manage customer accounts separately from the rest of the store users. For customer data maintenance, refer to the Communications > Customers section.
The maintenance procedures are the same regardless of the page.
From there, you can add, edit, delete, filter, or search for a customer profile, as well as see all orders placed by a specific customer. If you want to give discounts to a specific set of customers, then you can create memberships and allow customers to join in groups.
