Charge Tables
Each carrier has specific rate and zone data. This data is used with specific algorithms to determine freight cost estimates. Some carriers provide this information directly to Precision on request. Other carriers provide the data only to the shipper. Precision supplies carrier rate and zone data to the shipper as part of a PSL installation file for Precision network carriers.
Precision does not provide carrier and zone data for TL/LTL carriers. You must upload rates from files or create them manually within PRECISION.
