The invoice says one thing. Your rate card says another.
Carrier bills are built from base rates, fuel and surcharges on legacy systems with a proven error rate. Nobody has time to check them line by line.

Frequently asked questions
How accurate are carrier invoices?
Carrier invoices typically show a 2% to 6% discrepancy between what you are billed and what you actually owe under your contracted rate card. Errors come from base rates, fuel surcharges and oversize fees applied on legacy billing systems.
What is a carrier invoice audit?
A carrier invoice audit reconciles each line on a shipping invoice against the rate card you contracted, identifying misapplied surcharges, wrong zones, incorrect dimensional charges and rate mismatches so they can be claimed back as credit.
Can I not just check invoices myself?
In principle yes, but a mid-sized retailer receives thousands of invoice lines a month, each needing a match to a shipment and a contracted rate. Manual sampling catches the largest errors and misses the systematic small ones, which is usually where most of the money is.
How far back can discrepancies be claimed?
This depends on your carrier contract, which typically sets a window for raising billing disputes. Shipherd works forward from the point of connection and flags historic discrepancies where the window is still open.
Does this need my carrier's cooperation?
No. Shipherd works from the invoices and rate cards you already hold. Nothing needs to be requested from the carrier to begin.
What does it cost?
You only pay us if we recover. The fee is a share of the credits actually returned to you.

Amazon owes you for refunds where the item never came back. Finding those means reconciling three separate reports against each other.
