A method and system for interfacing with an existing order processing system to track orders to the unit level. The unit order system provides a unit order database that includes a record for each unit of each item of each order in the order database of the existing order processing system. The existing order processing system is used in its normal manner to update the order database. The unit order system periodically accesses the order database to identify new or changed orders. The unit order system then updates the unit order database to reflect the new, changed, or canceled orders. When a new order is identified, the unit order system adds a record to the unit order database for each unit of each item of each new order. The unit order system can track ship date, order date, cost information, and so on at the unit level.
