Abstract: A method and a system for providing an alternative fulfillment for a buyer's unfulfilled order are described. The system has an order fulfillment issue detection module, an alternative fulfillment qualification module, a replacement item matching module, and a replacement item order module. The order fulfillment issue detection module detects a fulfillment delay of an item in an order placed in an online marketplace. The alternative fulfillment qualification module determines whether the fulfillment delay qualifies for an alternative fulfillment order. The replacement matching module determines a replacement item for the item. The replacement item order module cancels the order and replaces the order with the alternative fulfillment order for the replacement item.

Abstract: A flexible shipping delivery system has an online marketplace interface, a client interface, a shipping carrier interface, and a flexible shipping delivery engine. The online marketplace interface communicates with an online marketplace application. The client interface communicates with a client that places an order for an item on the online marketplace application. The client interface receives a shipping delivery preference of a user of the client. The shipping carrier interface communicates with a shipping carrier server. The shipping carrier server provides a tracking shipping status of the item. The flexible shipping delivery engine adjusts a delivery option of the item based on the tracking shipping status of the item and the shipping delivery preference.
