Ask a dispatch service how the month went and you will usually hear one of two numbers: how many loads they booked, or your average gross rate per mile. Both can rise in a month your bank balance falls. Neither is a lie, and neither is an answer.
The gap between those numbers and your margin is not a reporting problem. It is an incentive problem, and it is visible in how the desk is paid.
The incentive under most dispatch deals
A dispatcher paid a percentage of the loads they book is paid to book loads. Not to book good ones, not to protect a rate floor — to book. That is a small misalignment, and small misalignments compound over a few hundred loads.
Consider the decision it produces. A marginal load available now versus a better load that takes another half day to find: for the desk, the first one pays today and the second one might not close at all. For the truck, the first one commits equipment, hours and fuel to a lane that was never worth entering.
This does not require anyone to act in bad faith. The incentive points slightly away from your interest, and volume does the rest.
What gross rate per mile hides
Gross rate per mile is the number most often quoted and the easiest to raise without helping anyone. It describes the loaded miles and ignores everything that turns a rate into money kept:
- Deadhead. A strong rate reached by running empty for two hours can pay worse than a weaker one at the back door.
- Accessorials. Whether detention, layover and TONU were documented and collected, or quietly absorbed.
- The fee, and what it is calculated on — the same percentage means different money depending on the base.
- Lane quality. Whether the load set up a reload or stranded the truck somewhere cheap.
- Time. Two loads at the same rate are not the same load if one sits four hours at the dock.
The number that cannot be gamed
Net profit per mile — what is left per mile the truck turned, after fuel, after costs, after the dispatch fee — cannot be raised by booking more or by quoting a better headline rate. It only moves when the load was actually worth taking.
Measured on that number, a desk starts behaving differently, because the behaviour and the pay finally point the same way:
- Holding the rate through a counter rather than taking the first offer.
- Planning the week as a loop so the premium load does not cost an empty return.
- Chasing detention and TONU, because uncollected accessorials come straight off the figure.
- Checking broker credit, because a load that does not pay is worse than one never booked.
- Turning down freight that books easily and pays poorly.
That is the difference between a service that answers the phone and one that runs an operation.
Questions that expose the incentive
Five questions, asked of anyone quoting for the work. The value is less in the answers than in whether they arrive plainly or arrive hedged:
- What is the percentage calculated on, and what else can appear on the invoice? A complete list should come back immediately — the second half of that question is the one that finds surprises.
- Who keeps detention, layover and TONU, and who does the chasing when a broker declines the first time?
- Is there a contract, a minimum, or forced dispatch — and what happens to my authority and broker setups if I leave?
- How is success on my account measured, in a sentence? If the sentence contains loads booked or gross rate, you have the answer to every other question.
- Who will actually be working my trucks, how many others do they cover, and can I reach them at 2 AM?
A desk that has thought about this has the numbers ready. A desk that has not will move the conversation back to volume, which is the tell.
None of this requires trusting a vendor's reporting. Net profit per mile is computed from settlements you already hold: revenue, fuel, fixed costs, the fee, and total miles turned. Run it for a month of self-dispatch and it becomes the baseline every quote afterwards has to beat — which is the only version of this argument that does not depend on who is making it.
