Who each one works for
A freight broker is a licensed intermediary between shippers and carriers. They hold their own FMCSA broker authority and a surety bond. They contract with the shipper, contract separately with you, and their income is the spread between the two. That spread is theirs and you do not see it.
A dispatcher is your agent. They work under your operating authority, not their own. The rate confirmation is made out between you and the broker or shipper directly, so you see the full rate on the load, and you are paid directly or through your factor.
That is the entire difference and it decides everything else.
Side by side
- Whose authority the load runs under — broker: theirs. Dispatcher: yours.
- Who the shipper contracts with — broker: the broker. Dispatcher: you.
- Do you see the full rate — broker: no, only your side. Dispatcher: yes.
- How they are paid — broker: the spread. Dispatcher: a fee you agreed, from you.
- FMCSA licence and bond required — broker: yes. Dispatcher acting purely as your agent: no.
- Whose safety record grows — broker: not yours. Dispatcher: yours.
Where it gets murky
The line matters legally. A dispatcher who starts negotiating on behalf of the shipper, or who takes a cut out of the load rather than billing you a fee, is doing something that looks a lot like brokering — and brokering without authority and a bond is not legal.
FMCSA has taken an increasing interest in this. The practical risk lands on you as well as them, because your loads are moving under your authority.
Two questions worth asking any dispatch service: do you hold broker authority, and are you paid by me or out of the load? If the money comes out of the load and there is no broker authority behind it, ask more questions.
Which one you actually want
You will deal with brokers regardless — most available freight is brokered, and a good broker relationship is worth having.
The choice is whether you also want somebody working your side of that table. A dispatcher is that person: they negotiate against the broker on your behalf, hold your rate floor, and are paid by you rather than out of the margin they can find.
If you are running your own authority and your own insurance, you want the relationships and the safety record accruing to your business. That only happens when the loads run under your numbers.
