A method of managing a supply chain comprises providing at a customer interface module a plurality of order fulfillment options to a customer, and receiving from the customer a selection of a particular order fulfillment option. The method also includes receiving a first order from the customer, and receiving a first inventory status from a first distribution center. A first distribution center sends a first product to the customer in response to determining that the particular order fulfillment option comprises a fill-partial order fulfillment option, and a duration between the time that the first product is directed to be sent and the time when the first product is actually sent is determined. An alert is generated if the duration is greater than a predetermined duration.
