The short version
Capacity comes from three places: a board, a list of carriers who have run that lane for you before, and the phone. The board fills the first load; the list fills the tenth. If a lane will not cover, the cause is almost always one of four things, and only one of them is the rate. Work through them in order before you raise the number.
Every broker has had the same afternoon: a load that covered in twenty minutes last Tuesday, posted since eight this morning, and the phone has not rung once.
The instinct is to raise the rate. Sometimes that is the answer. More often the load is invisible, or it is priced right for a market that has moved, or the carriers who would take it have never heard of you.
Where does carrier capacity actually come from?
Three sources, and a healthy brokerage uses all of them. A load board reaches carriers who are empty right now and do not know you. A lane list reaches carriers who have already hauled this exact run for you. The phone reaches the ones who are loaded today and free on Thursday, which is the freight nobody else is competing for.
| Source | Best for | What it costs you |
|---|---|---|
| Load board | A lane you do not run often, or a truck needed today | Vetting time, because you do not know who is calling |
| Your own carrier list | Repeat lanes, tight appointments, anything with a requirement | The months it takes to build, and paying on time to keep it |
| Outbound calls | Freight two or three days out, and regions with thin posting | Time. It is the highest-effort and highest-yield of the three |
A board is where most brokers start and where too many of them stop. Posting a load properly is what decides whether it works at all: a posting missing the equipment type, real cities, a delivery window or the rate is filtered out before anyone reads it.
Why is my load not covering?
Work through four causes in order, because three of them are free to fix and only the fourth costs money. The posting is incomplete, the market has moved, the carriers who see it do not know you, or the rate is genuinely under the lane.
- Check the posting before the price. Equipment stated specifically, real origin and destination cities, appointment windows with times, weight, commodity, requirements, and the rate on the listing. Anything missing removes you from the comparison rather than from the market.
- Check which way the market is running. A lane out of a head-haul market covers itself; the same lane inbound to it does not. If the trucks in that region are all pointed the other way, no amount of posting reaches them.
- Check whether they know you. A carrier who has not hauled for you looks up your authority, your bond and your payment reputation before calling. A new authority with a high rate and urgency attached is the profile good carriers avoid.
- Then look at the rate. If the first three are clean and it still will not move, the number is under the lane. Raising it late costs more than posting it right the first time.
Building a list that covers freight for you
The board is how you meet a carrier. The list is why the next one is a two-minute phone call. It takes months and there is no shortcut, but the mechanics are simple.
- Record the lane, not just the carrier. A carrier is not "good", they are good on Dallas to Atlanta with a reefer in the summer. Store what they actually ran and when.
- Note their equipment and their limits. Trailer type, whether they tarp, whether they will take a liftgate load, hazmat endorsement, TWIC. Those constraints save both of you a call.
- Note who answers, and when. A driver, a dispatcher, or a voicemail. Small carriers do not staff a phone room.
- Pay them when you said you would. This is the whole strategy. A carrier calls the broker who paid last time before they scroll a board.
- Keep the vetting current. Authority lapses and insurance cancels, so a list is only as good as its last check.
That last point is not admin. How to vet a carrier sets out the checks, and the reason they get repeated rather than done once.
Working the phone without wasting the day
- Call carriers delivering into your pickup area in the next two days. They are the ones about to be empty where you need a truck.
- Lead with the lane, the equipment and the rate. A carrier decides in the first sentence whether the rest of the call is worth having.
- Ask what else they run. A carrier who cannot take this load often knows who can, and small carriers refer each other constantly.
- Send the packet while you are still on the phone. Setup friction loses loads that were already agreed.
The loads that need a different approach
Some freight will not cover from a general posting no matter how it is written: oversize and permitted moves, hazmat, food grade with a wash-out requirement, team runs, and anything on a two-hour appointment window five hundred miles out. For those, start from the list and the phone and treat the board as the backup rather than the plan.
Equipment type matters more than most brokers assume, too. A load posted as "van" reaches dry van drivers who will skip a sprinter run, and the reverse. The equipment pages show what is actually posting for each type.
The bottom lineFix the posting, read the market, and pay people on time. Those three cover more freight than raising the rate does, and only the third one takes longer than an afternoon.
Frequently asked questions
How do brokers find carriers for a load?
Three ways, usually at once: posting on a load board to reach carriers who are empty now, calling from their own list of carriers who have run that lane before, and phoning carriers delivering into the pickup area in the next couple of days. The board wins the first load on a lane; the list wins the tenth.
Why is my load not getting covered?
Check four things in order. The posting may be missing something a carrier needs in the first five seconds, the market in that region may be running the other way, the carriers seeing it may not know your brokerage, and only then is the rate likely to be the problem. Three of the four are free to fix.
Is it worth posting the rate on a load?
Yes. Carriers price every listing against their own cost per mile, and one without a rate cannot be priced, so it gets skipped rather than called on. Hiding the number does not preserve negotiating room, it removes you from the comparison.
How do I build a list of reliable carriers?
Record the lane and the equipment rather than just the company, note who answers the phone and when, keep the authority and insurance checks current, and pay on the terms you promised. The last one does most of the work, because a carrier calls the broker who paid last time before they scroll a board.
How far in advance should I post a load?
As soon as you have the details. Carriers plan two and three days out, so a load posted the morning it ships is only competing for trucks that happen to be empty in that market that hour.
