Site Catalogs for Retail Accounts are either items a Supplier has added to a customers' (you, the retail account) "Order Guide" or an item that your site frequently orders.
Site Catalog translates to "Order Guides" in Supplier Accounts. A Supplier may add any item they sell to your Site Catalog, Suppliers also have the option to list the item at a special price, just for you.
In Retail Accounts, any user that has access to the site can view the Site Catalog from the Main Menu.
From the home page, click on the Main Menu bars.
Once the menu is visible, click "Site Catalog"
Clicking on the item name will provide more details about the item.
The "Site Item Details" page gives you the option to "Remove" the item or request QOH from the Supplier; this page also gives you Representative details and contact information if available.
