How to Recover Detention Charges You're Currently Writing Off

Detention is one of the most quietly expensive gaps in a brokerage's operation. Not because the charges are large individually, but because so many of them are never billed at all. This post covers how detention and demurrage actually work, why brokerages lose the revenue, and how to capture it automatically.

Detention and demurrage, quickly

Detention is the charge for holding a truck at a facility beyond the agreed free time for loading or unloading. Demurrage is the equivalent concept in the container and rail world — a charge for equipment or containers that sit past their allotted free time. Both exist to compensate for equipment that is stuck instead of earning.

The mechanics are simple: there is a free-time window, and once the clock runs past it, a per-hour or per-day charge applies. The difficulty is never the math. It is proving the time.

Why the money slips away

Recovering detention requires two things: knowing the truck was held, and being able to document it. Manual processes reliably fail at both. A rep juggling forty active loads is not sitting with a stopwatch on each one, and by the time a facility holds a driver for three hours, the moment to start the clock has already passed unrecorded.

A detention charge you cannot document is a detention charge you cannot bill. Most write-offs are really documentation failures.

So the revenue does not get disputed and lost — it never gets claimed in the first place. It simply evaporates into "the cost of doing business," quarter after quarter.

How to capture detention correctly

The fix is a disciplined, timestamped record on every stop:

1. Record arrival against the appointment window. The free-time clock cannot start if you do not know when the truck arrived.
2. Run the clock automatically. Track elapsed dwell time for every stop and container, not just the ones someone happens to remember.
3. Alert before free time expires. The most valuable moment is before the charge is locked in, when you can still push the facility or reposition.
4. Compile the documentation as you go. Timestamps, appointment details, and communication assembled in real time make a claim defensible.

Automating dwell-time tracking

This is precisely the kind of continuous, rules-based watching that a person cannot sustain across a full board but software does effortlessly. Detention and demurrage monitoring automation records arrival and departure against each appointment, runs the dwell clock on every load and container, alerts the desk before free time expires, and compiles the documentation needed to bill or dispute the charge.

It is one workflow inside the broader freight tracking automation layer — the same visibility that eliminates check calls also catches the dwell time you have been losing. Instead of relying on a rep to notice, the clock is always running and always documented.

Start here

Pick one lane or one problem facility where you suspect you are leaving detention on the table, and start capturing timestamps on every stop there. The recovered revenue usually makes the case on its own. To size the opportunity across your whole desk, run it through the ROI calculator.
