The commerce site provides visibility into catalog modification through the "last updated" timestamp feature. When managing multiple company and customer catalogs, users often need to track when changes were made to ensure they're working with current information or to see when the last update was made. The system automatically records and displays the date and time when each catalog was last modified or created, allowing users to quickly identify recently updated catalogs without manually tracking changes. This timestamp functionality helps maintain data integrity and provides valuable context when multiple team members are working with the same catalog database.
