A supply chain management system facilitates the efficient allocation and shipment of items. At least one customer having a geographical location associated therewith communicates with at least one client. The at least one client generates an order on behalf of the customer, where the order includes item data corresponding to at least one item and location data corresponding to the customer geographical location. A promising engine is in communication with the at least one client and with a plurality of warehouses in the system. The promising engine identifies a shipping warehouse from the plurality of warehouses based in part upon the location data corresponding to the customer geographical location, where the shipping warehouse is the nearest warehouse to the customer geographical location that has an ability to ship the at least one item to the at least one customer within a specified timeframe.
