Freight invoice audits usually mean someone opens a PDF, finds the carrier rate sheet, and checks every line by hand. It's slow, and expensive mistakes slip through. FreightAuditor takes your invoices and rate schedules - PDF, Excel, CSV, or plain text - and returns a status for each invoice: valid, duplicate, missing data, expired rate sheet, or needs human review. You get a clear list of what to pay, what to fight, and what to look at.
