  • Publication number: 20150052017
    Abstract: A system receives input from a seller agent of a first business organization and a centralized purchasing agent of a second business organization. The second business organization includes a plurality of decentralized business departments. The system generates an entitlement for an online purchasing site using the input from the seller agent and the input from the purchasing agent. The entitlement includes a validity condition and an impact condition. The system receives an input from one of the decentralized business departments, examines the validity conditions of the purchased entitlement, and in response to a determination that the validity conditions of the purchased entitlement are met, executes the impact conditions of the selected entitlement.
