How Does Parcel Auditing Work?

If you ship with UPS, FedEx, or DHL, you’re paying for services with specific guarantees and rules — but very few shippers have the time to check whether every invoice line follows those rules. That’s what a parcel audit does. Here’s how the process actually works.

Step 1: Your billing data goes to the auditor

You provide your parcel invoice data — usually an electronic invoice file, EDI feed, or a direct data feed set up with your carrier. TCR accepts all standard formats, so there’s no need to change how you currently receive your bills.

Step 2: Every line gets reviewed against carrier rules and your contract

This is the core of the audit. Every shipment is checked against:

  • Carrier service guarantees — was a guaranteed-delivery shipment actually late?
  • Your negotiated rates and contract terms — was the correct rate applied?
  • Surcharge rules — were address correction, residential, dimensional weight, and other accessorial charges applied correctly?
  • Lost or undelivered packages — was a package billed for shipping but never actually delivered?

Step 3: Claims get filed on your behalf

When an error is found, the auditor files a claim directly with the carrier. This step matters: carriers only honor most of these refunds when the claim is filed inside their own filing window, which is why ongoing auditing recovers far more than a one-time review of old invoices.

Step 4: You get paid — and get reporting

Refunds are collected and passed back to you. A good audit also gives you reporting on where your shipping costs and error patterns are coming from, so you can address root causes (like a warehouse team consistently mismeasuring packages) rather than just collecting refunds indefinitely.

What does it cost?

Reputable parcel auditors, including TCR, work on a contingency basis: the audit itself is free, and the fee is a percentage of what’s actually recovered. If nothing is found and collected, there’s no charge.
