An extension of either LTL/CIS or TL/CIS, this system routinely costs all traffic in each accounting period via interface with both cost and account profiles to produce a costed data warehouse as well as standard monthly reports for account and terminal profitability. Users can also custom design reports to be run on any period or combination of periods in the costed database. The costed database can be used for analysis of virtually any traffic breakdown to enable users to "zero-in" on both profitable and unprofitable traffic segments. Traffic segments can also be re-costed under other "what-if" scenarios to enhance decision making and shipper negotiations. The system can be interfaced with onboard computers and/or bar code readers to allocate costs on the basis of the actual circumstances of each shipment's movement.
