The cheapest-looking rate table is not always the cheapest carrier. Two agreements with similar linehaul rates can produce very different invoices once minimum charges, fuel mechanics, dimensional rules, and accessorial triggers are applied to your actual shipments. Contract review is the work of making that difference visible before you sign — and rate analysis is how you do it on real data rather than a handful of sample lanes.
The sections below move from the contract itself, to the terms that change the invoice, to the service and mode decisions around it, and finally to the ongoing monitoring that keeps a signed contract honest.
How these topics fit together
A contract review that stops at the rate table will miss most of what shows up on the invoice. Start with the agreement and a structured scorecard, then learn the mechanics — dimensional weight, accessorials, reweigh and reclass — that actually move the bill. Decide mode and partner deliberately, because the best contract for parcel is rarely the best contract for LTL. Then connect the signed agreement to ongoing monitoring so drift is visible.
This hub sits beside the Freight Cost & Invoice Intelligence hub, which covers diagnosis and invoice audit in depth, and the Logistics Data, Freight Invoice Data, and AI hub, which covers the data you need to run rate analysis on your own shipments.
Frequently asked questions
What should shippers review in a carrier contract?
More than the base rate table: discounts and how they apply, minimum charges, the fuel index and update cadence, accessorial rates and triggers, dimensional and billing-weight rules, re-weigh and reclass rights, service and transit commitments, liability and claims terms, and renewal and GRI mechanics. The full framework is in how to evaluate carrier contracts.
Why is the lowest rate table not always the lowest actual cost?
Because minimums, fuel mechanics, accessorial triggers, dimensional weight, and reweigh/reclass adjustments all stack on top of the linehaul rate. A lower base rate paired with a higher fuel index or aggressive dimensional rules can produce a higher landed cost on your real mix. See dimensional weight and accessorial charges.
What is carrier contract rate analysis?
Modeling how a contract performs against your real shipment profile — applying its rates, minimums, fuel, and accessorial rules to a representative set of your shipments to estimate landed cost — rather than checking a few sample lanes. The Carrier Contract Scorecard structures the qualitative side of this assessment.
How do accessorial charges affect carrier contract performance?
If residential, liftgate, limited access, appointment, re-delivery, and handling events are common in your network, they are part of the cost model — not edge cases. A strong base rate with loosely defined or expensive accessorials can underperform. Audit them with the accessorial audit workflow.
How often should carrier contracts be reviewed?
Formally at renewal, but monitored continuously. GRIs, fuel movement, and mix shift change effective cost between renewals. A monthly check on cost per shipment, accessorial share, and billed-versus-actual weight shows drift early — see freight cost creep.
