A system and method of interactive cataloging of products and services by end users across multiple sales and marketing channels provide each end user with access to domain-independent catalog data from a plurality of vendor organizations through a catalog server system. Anonymous end user cataloging actions of products and/or services across multiple manufacturing, distribution, and retailing channels create personalized profile instances that are based on stored vendor catalog profile templates in the catalog server system, and stored in the end user's personalized electronic catalog as pre-sale digital receipts. An end user's personalized electronic catalog(s) can be shared with peers using mutual agreement permissions as managed by the catalog server system. Pre-sale digital receipts are used to provide a safe, secure, and convenient method for modifying an end user's actionable cataloged items from a pre-sale status to purchased status when purchased and to provide a traceable audit trail for each cataloged item or purchased item in order to facilitate respective pre-sales channel activities and post-sales channel support and services.
