Why Small Carriers Write Off Detention

Four reasons account for most unbilled detention at small carriers: the rate confirmation had no enforceable terms, the facility wouldn’t sign the paperwork, the claim was worth less than the time to chase it, and nobody wanted to risk the lane.

Three of those are sound reasoning. The fourth is a fear that mostly points at the wrong thing, and it’s the one quietly costing the most.

The four reasons

No enforceable terms. The rate confirmation said “detention per broker policy,” or “subject to shipper approval,” or nothing at all. Without a named hourly rate and a named start trigger agreed before dispatch, there’s nothing to bill against — and no statute fills the gap.

No documentation. The receiver wouldn’t write times on the bill of lading. Missing or illegible timestamps are the single most common reason claims get rejected, and brokers frequently decline even when GPS and ELD records clearly show the truck sitting there.

The admin math. Compiling the packet, submitting it, and chasing it twice takes real dispatcher hours. Against a $50 to $100 line item, that’s a losing trade.

Relationship risk. Fear of friction with a broker who gives you steady freight, or of ending up on a do-not-use list.

Three of these are correct. One probably isn’t.

The first three are accurate assessments of a real situation. A claim with no contractual basis genuinely can’t be collected. A claim with no timestamps genuinely gets denied. And spending ninety minutes to recover $60 genuinely loses money.

The fourth is different, and it’s worth examining because it’s doing more damage than the others.

What brokers actually say about being billed

Carrier surveys consistently find widespread belief that invoicing detention damages broker relationships. Broker-side sources say something different.

Broker education materials and broker community discussion both hold that professional, well-documented detention billing doesn’t harm the relationship, and that paying legitimate detention builds carrier retention. Treat that as what brokers say about themselves rather than as established fact. The mechanism is straightforward: the broker passes the claim through to the shipper. If you provided advance notice and a signed BOL, the broker isn’t out any money. Processing it is administrative.

So the fear isn’t irrational, it’s misattributed. Carriers avoid billing when the thing they should be avoiding is billing late and unannounced. Billing properly, in real time, is the version brokers say they don’t mind.

The admin math is real, and it’s the honest reason

Say plainly what most vendors won’t: if assembling a detention claim takes your dispatcher an hour, writing off claims under $100 is the correct decision. The arithmetic isn’t a failure of discipline. It’s arithmetic.

Which means the fix isn’t persuasion or willpower. Telling a small carrier to “bill every claim” without changing the cost of billing is advice that loses them money.

What the write-offs cost

Start with the hours. ATRI’s 2024 research put detention at 117 to 209 hours per driver per year depending on sector. At $60 an hour that’s somewhere between $7,000 and $12,500 of billable detention per driver, before you subtract what never gets billed and what never gets paid.

Three costs sit underneath it that don’t appear on any invoice.

Spot freight detains more. ATRI measured detention on 42.5% of stops for fleets operating in the spot market, against 39.3% across all stops. Facilities service their contracted carriers first, and small carriers run more spot freight. Reefer is worse again, at 56.2%.

You lose loads, not just hours. Detention pay never compensates for a dispatch you couldn’t take; that’s linehaul you didn’t run, and it doesn’t appear on any accessorial invoice.

Drivers notice. ATRI found 44% of customer facilities offered no restroom access during detention and 78% had no lounge or waiting area. The average Canadian truck driver is now around 49, and Trucking HR Canada reports the supply of experienced drivers shrinking. Unpaid dock time is a standard reason drivers give for leaving, and replacing one costs more than years of detention claims.

There’s also the uncomfortable structural point: because an hour of truck time costs more than an hour of detention pay, even a fully collected claim leaves you behind — the full arithmetic is here.

The cheapest fixes, in order

None of the first three cost anything.

1. Fix the rate confirmation at intake. Push for a named hourly rate, a named start trigger, and a cap you’ve actually read. This is free, it happens before the load, and it’s the difference between a claim and a request.
2. Send the notice during the wait. Broker agreements commonly require the carrier to advise before the charge is incurred, and treat failure to do so as forfeiting the right to collect. Not a set number of minutes’ warning: just before the clock starts. This single habit converts more write-offs into collections than anything else on the list, and it costs one message.
3. Standardize the refused-to-sign routine. Driver writes the times on the BOL by hand, notes the refusal, gets the clerk’s name, photographs it, sends it in on departure. Free, and it rescues claims that would otherwise die at the gate — the exact routine is here.
4. Then reduce the assembly cost. Once the first three are habits, automation is what moves the write-off threshold down to where small claims become worth collecting.

What’s still worth writing off

Not everything should be chased, and pretending otherwise wastes the capacity you need for the winnable ones:

• Claims where no notice was sent during the wait. Usually a contractual waiver.
• Claims on rate confirmations with no detention terms. Nothing to enforce.
• Anything under an hour of billable time, as long as assembling it still costs real labour.

That third one flips the moment assembly is free, which is why it’s the threshold worth attacking rather than the claims themselves.

What to do next

Pick your ten most recent write-offs and sort them into the four reasons. The distribution tells you what to fix. Mostly missing terms means it’s a rate confirmation problem you fix at intake this week. Mostly missing notice means it’s a dispatch process problem. Mostly “not worth chasing” means the assembly cost is your bottleneck.

That last one is the one we built for. DwellWatch detects the wait from ELD data and assembles the claim, which is what makes small claims worth collecting at all.
