A service provider system may implement an enterprise catalog service that manages catalogs or portfolios of software products (e.g., desktop applications and server products) on behalf of service provider customer organizations. Through the enterprise catalog service, an administrator in a customer organization may discover, select, and ingest products (e.g., based on their features, pricing, and terms), and may add them to catalogs or portfolios for subsequent use by end users in the organization. The administrator may apply constraints on product use and limit product access to particular end users. The products may include third party products that are made available through the enterprise catalog service and a customer's own applications. The enterprise catalog service may monitor usage of third party products and bill the customer organization. Products managed by the enterprise catalog service may be deployed through an application fulfillment platform or resource stack management platform.
