When to Write It Off
More than half of detention invoices are never paid. A share of those are pursued anyway, through several rounds of correspondence, for amounts smaller than the staff time spent. For a software-oriented reference on recorded work time and accountability, remote employee monitoring software.
Knowing when to stop is a commercial skill, and it is separate from being right. For broader freight and commercial context, see Land Line.
The arithmetic
Work out your cost per round. Assembling the claim, the follow-up, the escalation, the internal discussion. For most operations a contested charge costs somewhere between thirty minutes and two hours of somebody's time per round.
Then compare it to the amount. A $150 charge pursued through three rounds has consumed more than it can return, and that is before the relationship cost.
And weight by the probability of collection. A well-documented claim against a facility that pays is worth pursuing. An undocumented claim against a facility that never pays is a lottery ticket with a staff cost.
Five signals to stop
One. You cannot produce the evidence. No independent timestamp, no notification at the time, no quoted clause. The claim will not improve with correspondence, and pursuing it teaches the other side that your claims can be refused.
Two. The contract does not support it. If the rate confirmation says "after 2 hours" with no start event, you are arguing an ambiguity, and ambiguity favours whoever holds the money.
Three. You have been paid on the pattern instead. If the lane was repriced to reflect dwell, collecting the detention too is charging twice — and carriers usually have priced it whether or not they said so.
Four. The relationship is worth more. A legitimate consideration and one to make consciously rather than by default. Writing off a charge to keep a good customer is a decision; forgetting to pursue it is not.
Five. The amount is below your own threshold. Which you should have, in writing, so it is a policy rather than a mood.
Writing off without conceding the position
The part people get wrong. A silent write-off teaches the other side that the charge was never real.
Send the write-off in writing. We are not pursuing the $180 detention on load ABC-12345. For the record: gate in 14:02, gate out 17:41, free time expired 16:02, notification sent 16:05. We are treating this as a goodwill adjustment rather than a withdrawal of the claim.
Three things follow. The event is documented, which matters if it becomes a pattern. The other side knows a concession was made. And your own records still show the dwell, which is what you need at renewal.
And log it as dwell cost, not as zero. A written-off charge is still an hour you lost. If it disappears from your data because it was not collected, your lane pricing will be wrong.
What to do instead of pursuing
Take it to the contract. One conversation at renewal about the start event is worth more than twenty disputed invoices, and it addresses the cause rather than the instance.
Take it to the pattern. Twelve write-offs at this facility this quarter, totalling $2,100, none pursued. That is a number a customer's operations side will respond to when individual invoices did not.
Or take it to the rate. Price it and say why.
All three are cheaper than correspondence and all three change something.
For the paying side
The symmetric advice, because a receiver who refuses everything is also making an arithmetic error.
Pay the well-documented ones promptly. It costs less than disputing and it establishes that documentation is what you respond to — which improves the quality of what you receive.
Refuse the undocumented ones with a reason. A rejection saying what would make it payable is a negotiation; a silent one guarantees the next invoice is equally bad.
And notice your own write-off rate from the other direction. If carriers are quietly abandoning claims against you, your dwell is not costing you what your accessorial spend suggests — it is costing you in prices you cannot see.
The short version
- A contested charge costs thirty minutes to two hours of staff time per round; compare that to the amount before pursuing
- Five signals to stop: no evidence, no contractual support, already priced into the lane, relationship value, or below your threshold
- Have the threshold in writing so it is a policy rather than a mood
- Write off in writing, stating the facts and calling it a goodwill adjustment rather than a withdrawal
- Log written-off charges as dwell cost, not zero, or your lane pricing will be wrong
- Take it to the contract, the pattern or the rate — all three are cheaper than correspondence and all three change something
