In a Multivendor X-Cart store, the store administrator has full control over the ratings with which buyers describe their shopping experience based on the level of service they get from vendors.
First, the store administrator can choose what type of vendor ratings they want. Multivendor stores can use two types of vendor ratings: based on “detailed categorized rating” and based on “product rating”.
Vendor ratings based on “detailed categorized rating” are a feature available in Multi-vendor by default; such ratings are formed of order ratings provided by customers. The rating is done in the following categories:
Item description (whether the item received is as described);
(if applicable) Shipping Speed.
In each of the above-named categories, a customer whose order has been delivered can rate their shopping experience by giving one to five stars. The rating info provided by different customers for a vendor is summed up, and the resulting rating summary is shown as the overall vendor's rating.
Vendor ratings based on “product rating” are a feature available only in Multivendor stores that use the add-on Product reviews. Such ratings are the result of an aggregation of product ratings that are given by customers to products they have purchased from vendors. More info is available in the section Product Reviews Add-on: Usage with Multivendor.
Second, the store administrator can manage the email notification “Customer has rated the order”. For more info, see Managing Multi-vendor Email Notifications.
Third, the store administrator can edit/adjust the ratings that vendors get from customers via the Vendor Ratings section (Users > Vendor ratings):
