← Freight accessorial invoice auditor
Detention is billed as hours after free time. The invoice often shows a dollar amount and no clock. This page subtracts contracted free time from the minutes on dock, multiplies the remainder by the hourly rate on the confirmation, and compares that to the billed line.
On the default 180 minutes on dock, 120 free, and $75/hour, the clock leaves 1.00 billable hour — $75.00 expected. A $300.00 billed line is $225.00 above the clock, as if 4.00 hours. Paste your timestamps and the rate on the confirmation. This page does not fetch a carrier portal.

Complementary to the multi-line accessorial auditor (every billed extra), fuel percent versus linehaul, and who holds the cash after you pay the carrier. This page is only the detention clock on one line. The calculator is arithmetic, not advice. It does not claim the timestamps you typed are the ones the carrier recorded.
Compare the billed detention line to the dock clock after free time. On 180 minutes on dock, 120 free, and $75/hour, 1.00 hour is billable — $75.00 expected. A $300.00 billed line is $225.00 above the clock, as if 4.00 hours. That is a review of the line, not a determination that the charge is wrong.
Billable hours are only the minutes after contracted free time. If the truck was on dock 180 minutes and free time is 120 minutes, 60 minutes — 1.00 hour — is billable at the contract hourly rate. The page does not decide whether the timestamps you typed are correct.
