This calculator vs. Trax Technologies

Two different shapes: Trax Technologies audits and pays freight invoices at scale across a shipper's whole carrier network, under an ongoing enterprise account. This page is a free, private worksheet for one question — does this one carrier's invoice, checked line by line against your own contract rates, actually owe what it billed, before you pay it.

What each tool is for

Trax Technologies is enterprise transportation spend management (TSM) software, sold under an ongoing account to shippers with freight to audit and pay across many carriers and lanes. Its core freight audit and payment (FAP) service ingests carrier invoices — commonly through EDI and integration with a shipper's TMS or ERP — audits each line against the shipper's contracted rates at scale, and can disburse payment to the carrier on the shipper's behalf, alongside spend visibility and analytics reporting across the whole freight network. Setting it up is an enterprise engagement: onboarding, carrier and rate-card integration, and a contract, not a self-serve signup. Trax's own site is not reachable from this session to confirm today's specific plan names, integrations, or pricing, so only its well-documented identity and category are stated here: nothing about it is invented, and no dollar figure for it appears on this page.

This calculator does none of that. It does not integrate with a TMS or ERP, ingest invoices by EDI, or pay a carrier. It takes one carrier's invoice — imported as a CSV export or pasted rows, or typed by hand line by line — maps its columns, and checks each accessorial line against a contract rate card you type once: flat amounts, or per-unit rules for hour, minute, day, cwt, pallet, piece, mile, or stop, each with its own free allowance and cap. It flags duplicate lines, amounts above the rate card, missing codes, and missing evidence, checks a detention charge against the dock clock and a fuel surcharge against the contracted percent of linehaul, and compares eating a line, billing it to the customer, or paying first and filing for a credit. It runs free in any browser, keeps no account, and the file you import is read locally and never uploaded.

Question	Where to answer it
I run a shipping operation with freight moving on many carriers and lanes, and need invoices ingested automatically by EDI, audited at scale, and paid to the carrier.	Trax Technologies, or a comparable transportation spend management platform.
I have one carrier's invoice, or one line on it, and want to check it against my own contract rates right now.	This calculator — free, instant, private, no account.
I need a detention or storage charge checked against free time and an hourly or daily rate, or a fuel surcharge checked against a contracted percent of linehaul.	This calculator's detention-clock and fuel-surcharge checks.
I need my freight invoices actually paid to the carrier, not just reviewed.	Trax Technologies, or a comparable FAP platform — this calculator has no payment feature at all.
Should I eat this accessorial line, bill it to the customer, or pay first and file for a credit?	This calculator's cash-outcome comparison.
Do I need an account, an EDI integration, or a contract to use the tool?	This calculator: no. Trax and comparable FAP platforms are sold through an enterprise account.

Most freight-paying shippers get different value from each: Trax Technologies (or a comparable transportation spend management platform) for automated, at-scale invoice audit and carrier payment across a whole freight network under an ongoing account, and a private calculator like this one for an instant, no-login check on one invoice or one accessorial line against contract rates before it is paid. This page's own figures are a review of the lines you entered, not an audit run, a payment, or a determination that a charge is wrong.

This tool needs no account and no sign-in: it is a static page, the arithmetic runs in your browser, and once it has loaded it keeps working with the connection off. Imported files are read locally and never uploaded.

Common questions

Should I use this calculator or Trax Technologies?

They do different jobs, and a shipper with real freight volume will likely end up touching both eventually. Trax Technologies is enterprise transportation spend management (TSM) software, sold under an ongoing account: its freight audit and payment (FAP) service ingests carrier invoices, commonly through EDI and integration with a shipper's TMS or ERP, audits each line against the shipper's contracted rates at scale, and can disburse payment to the carrier on the shipper's behalf, alongside spend visibility and analytics across the whole freight network. Setting it up is an enterprise engagement — onboarding, integration, and a contract, not a self-serve signup. This calculator does none of that. It takes one carrier's invoice — imported as a CSV or pasted rows, or typed by hand — checks each accessorial line against a contract rate card you type once, flat or per unit with a free allowance and a cap, flags duplicates, overages, missing codes, and missing evidence, checks a detention charge against the dock clock and a fuel surcharge against the contracted percent of linehaul, and compares eating a line, billing it to the customer, or paying first and filing for credit — instantly, in the browser, with no account, no integration, and nothing uploaded. A shipper running invoices at scale across many carriers and lanes, who needs the audit automated and the carrier actually paid, is better served by Trax Technologies or a comparable platform; a shipper checking one invoice, or one detention or fuel-surcharge line, against contract rates before paying it is in the right place here.
