Three different products share the phrase carrier bidding software, and two of them are built for the other side of the table. This is the taxonomy: what shipper bid platforms, carrier-side RFP pricing software, and TMS bid modules each actually do, a ten-second verb test for telling them apart on any product page, and the signs you are reading about software whose success metric is your revenue.
Two comparisons decide most pricing conversations: what you quoted this shipper last year against what you are quoting now, and what you quote one shipper against what you quote another. Neither is apples to apples until fuel comes out of it. Between the last bid season and this one diesel moved $1.91 a gallon, and every schedule read it differently.
Fuel surcharge schedules assume diesel has one price. It does not. On the August 24, 2026 print a gallon cost $5.35 in the Lower Atlantic and $7.04 in California, and the schedule paid both trucks the same. That spread is 23 cents a mile of real money, and which side of it you are on is decided by where your lanes run, not by how well you operate.
A reefer unit burns roughly 0.8 gallons of diesel an hour at fresh setpoints and about 1.5 gallons an hour frozen. Fuel surcharge tables are built on a different number: tractor miles per gallon. A reefer unit does not care about your miles. It burns by the hour, by the setpoint, and by how long the doors are open, which is why the same schedule that nearly keeps a dry van whole leaves a frozen load 31 cents a mile short. Here is the full cost model and what to ask for at bid time.
The shortest true answer: EnrouteAI helps truckload carriers price shipper RFPs. This page is the longer answer, stage by stage, plus what EnrouteAI deliberately is not.
A shipper's bid file lands with 1,800 rows and a two-week deadline. Here is the workflow a carrier's pricing team actually runs, step by step, and the places where it quietly goes wrong.
Shippers send the bid. Someone on the carrier's side has to price it. This guide explains the software category built for that job: what it does, what it is not, and the point where a spreadsheet stops being enough.
A fuel surcharge is supposed to make fuel a pass-through. In practice, the schedule decides who eats the swings. This is the manual we wish every truckload pricing analyst had: the three schedule types, the real math on a real lane, and the gaps that quietly cost carriers money.
