A rate change after booking can happen at four moments: before you sign the rate confirmation, after you sign but before pickup, at the dock, and after delivery. Your leverage is strongest early and weakest once the freight is on your trailer. This guide explains what a signed rate con does and does not protect, gives short messages you can paste at each stage, and lists what to save as evidence. It then covers recovering short pay: a written demand, a check of the broker’s bond status, and a claim against the bond when needed. Deadlines exist for every step, so act early. This is general information, not legal advice.

You said yes to a load at one price. Now the number on the page is lower, or a new stop appeared, or the payment arrived short. It feels like the deal changed without you. What you can do depends on the moment it happened, because your options shrink as the freight moves.
If you are not sure what each line of the document means, start with what a rate confirmation is. For spotting problems on the page itself, see how to read a rate con and spot a skim.
The rate con (rate confirmation) is the document that records the price and terms of one load. The number can change before it, after it, at the dock, or after delivery. Each moment gives you different leverage.
| Moment | How it usually looks | Your leverage |
|---|---|---|
| Before you sign the rate con | The rate con arrives with a lower number than the phone call or load post | Highest. Your truck has not moved and you can decline |
| After signing, before pickup | A call or email says the shipper “cut the budget” and offers less | High. You can ask for a revised document or walk away, though you may lose time |
| At the dock | A stop is added, the weight or commodity differs, or a new document appears | Lower. You are already there, and refusing may cost you hours |
| After delivery | Payment arrives short, with a deduction nobody mentioned | Lowest. The freight is delivered, so you rely on paperwork and the broker’s bond |
The pattern is simple: the later the change, the more your evidence matters and the less your ability to say no. That is why the first two stages are the best place to push back.
A signed rate con records the terms both sides agreed to, including the rate, stops, and pickup and delivery times. Treat a one-sided change after signing as something you have not agreed to until you accept it in writing. A revised rate con should be a new document that you read and accept before you act on it. We know of no FMCSA rule that fixes the price of a brokered load after signing, so your protection is the document itself.
It does not protect everything. If the rate con says extra stops, detention or deductions are handled in a certain way, those clauses apply. If it refers to another contract, such as a broker-carrier agreement, read that document too, because the rate con may point to it for the rules. A verbal promise that is not on the page is hard to prove.
Whether a specific change counts as a breach depends on your documents and your state. Ask a transportation attorney if a large amount is at stake.
Keep messages short, polite and in writing. Email or text is better than a phone call, because a message has a timestamp. If you take a call, follow it with a message that summarizes what was said.
“Hello. The rate on the rate confirmation is $X. We agreed on $Y. Please send a corrected rate confirmation. I will not move the truck until I receive it.”
“I understand the shipper changed the budget. My rate for this load is $Y, as on the signed rate confirmation. If you want a different rate, please send a revised rate confirmation and I will review it.”
“The dock says there is an extra stop that is not on my rate confirmation. Please send a revised rate confirmation with the new stop and the new rate before I continue.”
If the dock cannot wait and you decide to go, write this first: “I am continuing under protest. I expect the added stop to be paid as an extra. Please confirm in writing.” For how extra time and stops are normally billed, see detention, TONU and layover pay.
Start saving on the first call. A dispute is usually won or lost on what you can show.
Keep one folder per load, in cloud storage and not only on your phone. Name files with the date and load number. If the weight or commodity on the paper looks wrong, read why the weight on a rate con can be a guess.
Work in this order. Each step builds the record for the next one.
Deadlines apply, and some are short. The 60-day window above is one. State law sets time limits for lawsuits, and some contracts set a window for disputing a payment. Do not wait months to find out. Check your rate con and broker agreement for the dispute window on the day you notice the problem.
Say, for illustration only, that you agreed to haul a load for $2,000. After delivery, the broker pays $1,800 and writes “adjustment” on the remittance. Your signed rate con shows $2,000 and has no clause allowing deductions. You send a written demand for the $200 difference with the rate con and POD attached. The broker replies that the shipper complained about a late delivery. Your check calls and timestamps show you were on time. That is the kind of record that supports a claim, which is why you save everything in advance.
Most short pay starts with a clause nobody read. Look for these before you sign:
The strongest habit is also the simplest: do not move the truck on a verbal number. If the price is not on a document you signed, treat it as not agreed. Politely say, “Please send it in writing.” A broker acting in good faith will do that in minutes.
A dispatcher can read the rate con before you sign, compare it with what was promised, and ask the broker for corrections while you drive. They can also keep the message trail organized if a dispute starts. A dispatcher cannot change the legal position, and they work from the same documents you do. Before you hire one, check them carefully with these six checks.
