Embodiments for providing a unified catalog include systems and methods that import catalog data from one or more underlying catalog systems. The systems identify items from the catalog data and modify at least one of item descriptions, item names, product categories, and item identifiers associated with the identified items. The systems further provide a unified user interface to a user for browsing the items, receive a request for at least one product selected by the user from the items, and send an order for the at least one selected product to the one or more catalog systems.
