The Liferay Commerce catalog is at the heart of any store site, storing and organizing its core content. It lists the products the store offers, and stores the information and relations necessary to organize and display them. The catalog tracks not only what items are for sale, but also inventory levels, product variants, and category assignments. It also organizes product files, such as images and user manuals, and contains pricing information.
To view the catalog, go to Site Menu → Commerce → Catalog. Its contents are displayed under the Products tab.
