How to Cut Detention Charges at Your Dock
Detention is the charge a carrier bills when its driver is held at a shipper or receiver beyond the free time agreed, commonly around two hours. A few charges look small on their own. Across a year of receiving, they add up, and carriers remember the docks where their drivers wait.
Why detention builds up
Most detention comes from a handful of repeat causes, not one bad day.
- Too many trucks booked in the same hour for the people and doors available.
- Appointments taken by phone or email and never put on the shared schedule.
- Loads that arrive without the paperwork or the order the warehouse expected.
- No clear arrival time recorded, so the warehouse can't tell whether the clock started at the appointment or when the driver pulled in early.
Step 1: Cap trucks per hour
Decide how many trucks each hour can really take at each warehouse, and don't book past it. If a holiday, inventory count or short-staffed shift means fewer, lower the limit for those dates instead of hoping it works out. Pickups and deliveries should share the same count, because they share the same doors and crew.
Step 2: Put every booking on one schedule
A self-service portal where carriers book open slots, checked against your real POs, removes the side bookings that cause pile-ups. Staff bookings for carriers who call go on the same calendar. When the schedule is the only way in, its capacity limit actually holds.
Step 3: Record arrival and departure as they happen
You can't dispute a detention invoice without your own times. Record the arrival, the start of loading or unloading and the departure at the moment they happen, not typed in later from memory. One-click steps that save the current time make this realistic on a busy dock.
Step 4: Count free time the right way
Free time usually runs from the appointment time, not from when the driver arrives. A driver who shows up an hour early hasn't started the free time early, and a driver who arrives late generally isn't owed detention. Check your carrier agreements, then count it the same way every time.
Step 5: Watch the clock during the day
Detention is cheapest to prevent in the last 30 minutes of free time, when moving a truck to the next open door still helps. A visible clock on each appointment, turning amber before detention starts, tells the dock lead which truck to work next.
Step 6: Review by carrier every month
Look at time on site, detention, late arrivals and no-shows by carrier and by warehouse. Patterns show quickly: a lane that always runs long may belong on drop trailers, and a carrier that arrives late most weeks may need a different appointment time.
How Live Unload helps
Live Unload caps appointments per hour at each warehouse, lets carriers book only real loads, and records dock times with one click per step. On Enterprise, a detention clock counted from the appointment time shows on every live appointment, time on site and detention go into your exports, and carrier scorecards summarize it all by month.
