Abstract: The system of the present invention includes one or more servers which communicate with one or more data storage devices and one or more programs. The storage devices include the activity data necessary for the system to generate results derived from a multi-driver cost system (such as activity-based costing) for a plurality of different users. Preferably, a plurality of users can provide raw general ledger data and other user-specific data to the system through a network, and the system, using its activity data associated with these types of users, can provide the users with cost and performance results in various forms. The system can automatically update the results for users from time to time.
