Our Story
Helping shippers stop overpaying carriers.
Transportation Accounting Network was founded in 1978 with one goal: help shippers stop overpaying carriers.
At the time, freight auditing was manual, slow, and inconsistent. TAN built its business around doing it better—and doing it right.
Today, TAN combines transportation knowledge, contract and legal awareness, modern data tools, and real-world dispute experience to identify and pursue recoveries.
Our post-audit services operate on a contingency basis: if we don't recover money, you don't pay.
Our Evolution
Nearly five decades of adapting to transportation.
From paper invoices to electronic data, the industry has evolved—and so has the way TAN helps shippers.
Transportation pricing and contracts become more complex.
Audit workflows move from paper toward electronic data.
National carrier networks and contract structures continue to evolve.
High-volume parcel auditing becomes increasingly automated.
Technology adds speed and visibility while expert judgment remains essential.
Nearly 50 years of freight audit experience.
What Hasn't Changed
Carrier billing mistakes still happen.
Contracts still contain risk, and transportation teams still have more to do than chase old invoices. TAN helps uncover and pursue what may have been overlooked.
