The user then searches an electronic marketplace, which is external to a remote procurement service and, subsequently, selects various items to be placed in a shopping cart or project. Upon checkout, the items are submitted for approval to the remote procurement service which is external to the reverse procurement service. The remote procurement service obtains approval and sends payment information to the reverse procurement service. Upon receive of payment information, the reverse procurement service then initiates a process for providing the approved items to the user.
