Abstract: An enterprise fulfillment system for order fulfillment from a heterogeneous fulfillment network is shown having a server configured to connect to a communication network to communicate with an ordering system and obtain inventory data from the nodes of the fulfillment network. The server receives a customer query regarding a product from the ordering system, identifies nodes in the fulfillment network stock of the product, and scores fulfillment options from the fulfillment network based on a routing schema. The server replies to the ordering system with rank ordered fulfillment options. The system may provide independent routing schema for different clients that provides different fulfillment options from the fulfillment network for each client. An interface may be provided permitting the routing schema to be revised by a client or based on dynamic data. The fulfillment network may include nodes from client, enterprise and vendor networks having different inventory, capabilities and cost.
