You got a quote. You budgeted around it. You told your customer what the freight would cost to move. Then the invoice showed up bigger than the number you agreed to, and now you’re the one explaining the gap to a boss or a buyer who doesn’t care whose fault it was.
If that’s happened to you, you already know the truth: in a lot of freight, the quote is a starting point, not a price. We think that’s backwards. A quote that holds should be the baseline, not a perk you’re grateful for. Here’s why partial flatbed prices with FlatbedLTL don’t move, and what makes other quotes drift after the freight is already rolling.
Why a “quote” turns into a bigger bill
Big LTL networks build their pricing on rules that let them recover cost after the fact. Your freight gets measured, classed, and re-rated, and if it’s low-density, long, or awkward, which describes most open-deck freight, the surcharges land later. The usual suspects:
- Density Minimum Charge — your freight is light for the space it takes up, so you get billed as if it were heavier.
- Linear Foot Charge — your freight is long, so you get charged for the trailer length it occupies regardless of weight.
- Cubic Capacity Charge — low-density freight that eats up trailer volume gets repriced.
- Capacity Load Charge — your shipment ties up too much of the trailer, so the rate climbs.
Each one is defensible on paper. The problem is that they hit after you’ve committed. You didn’t agree to a range. You agreed to a number, and the number moved. For the full breakdown of how these work, see our accessorial explainer.
How steep the swing can get
Here’s an illustrative example, not a quote, to show the mechanism. Say you ship a light but long piece of open-deck freight and get quoted a modest rate. Then the linear-foot and density rules kick in:
| Line item | What you expected | What can show up |
|---|---|---|
| Base quote | $500 | $500 |
| Density / linear foot re-rate | — | +$3,000 |
| Invoice total | $500 | $3,500 |
Those numbers are illustrative, not a rate. But the pattern is real, and if it’s ever happened to you, you remember it.
What “locked in” actually means here
A FlatbedLTL partial flatbed quote is locked in. It is not subject to the Density Minimum Charge or the Linear Foot Charge. We quote you a number for the deck space your freight needs, and that is the number.
That’s possible because partial flatbed prices differently on purpose. Instead of squeezing your freight into rules built for dry-van LTL, we put it on shared open-deck space alongside other partial loads. You pay for the portion of the deck you use, roughly under ten feet and under about 10,000 pounds is the sweet spot. Your freight isn’t a problem to surcharge. It’s a piece of the load.
That’s the “everybody wins” part. You get a price that holds. The carrier fills deck space that would otherwise run empty. The freight moves, often dispatching direct from origin to destination instead of bouncing through terminals where extra handling can break it.
Getting a quote that actually holds
A locked-in price starts with an accurate description. Three steps:
- Tell us the real dimensions and weight. Length, width, height, and weight, including anything that overhangs. Honest numbers up front are what let us hold the price later.
- Book pickup and securement with one point of contact. A person owns your shipment, plans the tie-downs against the cargo weight, and answers when you call.
- Rest easy with no surprise accessorials. The quote you accepted is the number you pay.
When partial flatbed isn’t the right fit
A locked-in price only helps if it’s the right mode. If your palletized freight is bigger than a regular LTL shipment but doesn’t need an open deck, ask about Volume LTL, shared dry-van economics without the full-truck price. If your load has outgrown partial and needs a whole trailer, oversized specialty open-deck, or reefer, that’s Comet National Shipping, our parent company. Pointing you to the right mode is how we keep your trust.
You shouldn’t need a logistics department to ship three pallets of steel, and you shouldn’t need to brace for the invoice. Send us the load that LTL won’t touch and get a locked-in partial flatbed quote at /get-a-quote, or call (800) 831-5376. We’ll give you a number, and it’ll be the number.
