This calculator vs. Cass Information Systems

Two different shapes: Cass Information Systems audits and pays freight invoices at scale across a shipper's whole carrier network, under an ongoing contracted relationship built for larger freight volumes. 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

Cass Information Systems (Nasdaq: CASS) is a publicly traded financial services company whose freight business, marketed as Cass Freight, provides freight audit and payment (FAP) processing to shippers: it receives carrier invoices — commonly by EDI or a direct feed from the shipper's TMS or ERP — audits each line against the shipper's contracted rates at scale, and disburses payment to the carrier on the shipper's behalf, alongside consolidated transportation spend data and reporting across the whole freight network. It is set up as an ongoing contracted relationship built for shippers with meaningful freight volume across many carriers and lanes: onboarding and integration, not a self-serve signup. Cass is also known for publishing the monthly Cass Freight Index, a widely cited industry benchmark of North American freight volumes and expenditures — a separate product from the audit-and-payment service itself. Cass'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 want a contracted service to ingest invoices by EDI, audit them at scale, and pay the carrier.	Cass Information Systems, or a comparable freight audit and payment provider.
I have one carrier's invoice — or one broker or small shipper's worth of them — and want to check it against my own contract rates right now, with no contract of my own to sign.	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 on my behalf, not just reviewed.	Cass Information Systems, or a comparable FAP provider — 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 a contract, minimum volume, or an EDI integration to use the tool?	This calculator: no. Cass and comparable FAP providers are sold as an ongoing contracted service.

Most freight-paying shippers get different value from each: Cass Information Systems (or a comparable freight audit and payment provider) for automated, at-scale invoice audit and carrier payment across a whole freight network under an ongoing contract, 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 — including for a broker or small shipper whose freight volume would not clear a FAP provider's minimum. 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 Cass Information Systems?

They serve different shippers. Cass Information Systems (Nasdaq: CASS) is a publicly traded financial services company whose freight business, marketed as Cass Freight, provides freight audit and payment (FAP) processing: it receives carrier invoices, commonly by EDI or a direct feed from the shipper's TMS, audits each line against the shipper's contracted rates at scale, and disburses payment to the carrier on the shipper's behalf, returning consolidated transportation spend data and reporting. It is set up as an ongoing contracted relationship built for shippers with meaningful freight volume across many carriers and lanes — an enterprise engagement with onboarding and integration, not a self-serve signup, and Cass is also known for publishing the monthly Cass Freight Index, a widely cited industry benchmark that is a separate product from the audit-and-payment service. 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 Cass or a comparable FAP provider; a shipper or broker checking one invoice, or one detention or fuel-surcharge line, against contract rates before paying it is in the right place here.
