A Closer Look at the ITS Process: Freight Audit and Payment, Simplified

Freight bills come in fast, in different formats, and often with just enough variation to make invoice review harder than it should be. When that happens, small errors, duplicate charges, and misapplied accessorials can quietly turn into real cost.

That is exactly why we built the ITS process.

Our freight audit and payment workflow is designed to bring order to the freight billing cycle by validating inputs, matching supporting documents, surfacing exceptions early, and creating a clear path to resolution before payment is ever released.

Below is a high-level look at how it works, step by step. (You can also view the full breakdown here: The ITS Process.)

1) Receiving Freight Bills

The process starts with receiving freight bills in whatever format your carriers (and your operation) require. ITS accepts:

• EDI (Electronic Data Interchange)

• Non-EDI electronic files

• Paper bills

• Voucher files

For EDI, our systems support standard transaction sets such as 210, 410, 310, 110, and 997. In the transportation world, the X12 210 is commonly used for motor carrier freight invoice details and provides a consistent structure for invoice data exchange between systems. If you want a standards-based reference for why that structure matters, the official definition of the X12 210 Motor Carrier Freight Details and Invoice is a good reinforcement, since it outlines the data framework many carriers use to transmit freight invoice detail.

Before anything moves forward, incoming files go through validation checks to confirm formatting is correct and to help catch early red flags like duplicate files.

2) Bill Match Program

Next, we match what we receive against the documentation you provide. Depending on your operation, that may include:

• Quote files

• Bills of lading (BOL)

• Load files

• Purchase order (PO) files

• Invoice files

The goal is simple: confirm the billed charges align with what actually shipped, what was agreed to, and what your internal records support. When something does not match, we flag it so it can be addressed quickly, while the details are still easy to validate.

3) Duplicate Checking

Duplicate freight bills can be costly, especially when they are buried in high volume billing cycles.

ITS performs a thorough review to identify duplicates, including:

• Exact duplicates (these are zeroed out)

• Possible duplicates (often tied to Pro numbers or BOL numbers)

When something looks questionable, an auditor reviews the details and makes the final determination.

4) Bill Auditing

This is where accuracy and accountability really take shape.

ITS audits freight bills to confirm documentation is complete and charges align with agreed-upon terms, including:

• Rates and contract rules

• Freight class validation

• Accessorial additions

• Customer specific business rules

Freight class accuracy matters because it can materially impact charges, especially in LTL shipping. If you want a quick, authoritative reinforcement on why freight class validation matters, this overview of NMFTA classification standards is a strong reference, especially when you are auditing LTL invoices where class drives rating.

We also use third-party verification systems to cross-check market rates where appropriate.

When variances are found, the bill is routed for review so your team can resolve discrepancies and provide clear payment instructions before anything is paid. If you want a second reinforcement that leans more “process discipline,” this resource on freight bill audit and payment best practices aligns well with teams that need repeatability, exception control, and fewer manual touches.

5) System Processing

Once freight bills pass auditing (or are resolved through review), ITS supports consistent coding and reporting.

If General Ledger codes are not already assigned, the system assigns GL codes to support clean internal reporting.

Freight bill aging is also available, which helps you manage funding requests on a weekly basis and maintain visibility into what is pending, what is approved, and what is ready for payment. If you want a neutral, government-published framework that supports consistent transportation invoice rules and rating references, the GSA Uniform Rules Tariff (PDF) is a helpful citation, especially for rule-based charge validation and standardized interpretation.

6) Invoice and Payment Files

After bills are audited and approved, they are available for funding by process week.

Weekly invoice communication can include summaries such as:

• GL Code Summary

• Location Summary

• Freight Detail

• Freight Amount

• Fee breakdown

Payment files can also be integrated with systems like SAP, JDE, or Oracle.

Once funding is confirmed, ITS issues payment directly to carriers via:

• ACH

• Wire transfer

• Paper check

• Credit card

A payment register is then provided with confirmation details, so you can close the loop with confidence.

Final Thoughts

Freight audit and payment should not feel like guesswork. The ITS process is built to reduce exceptions, prevent duplicate payments, and give you a consistent, accountable workflow from bill receipt to carrier payment.
