Cost structure / standard tiers
Appointment-related delay charges follow tiered structures based on wait time beyond the scheduled slot.
| Appointment Type | Typical Grace Period | Detention Rate After Grace Period |
|---|---|---|
| Live unload | 1-2 hours | $50-$100/hour |
| Drop trailer | N/A (no wait for unload) | Trailer detention if not picked up within agreed window, $50-$150/day |
| Will-call/open dock | None (no scheduled time) | Higher variance; detention often starts from arrival |
Some 3PLs also charge a missed-appointment or no-show fee, typically $100-$300, if a scheduled appointment is not used and not cancelled within a required notice window.
Risk mitigation / operational guidance
Confirm appointment type and grace period terms with the receiving warehouse before dispatching the truck, since detention rate and grace period assumptions vary significantly between facilities and are a common source of billing disputes. For live unload appointments at facilities with known wait-time issues, consider drop-trailer arrangements where feasible, which decouple the truck's schedule from the warehouse's unloading queue. Track actual arrival time, check-in time, and unload-complete time separately for each delivery — this data supports detention billing claims and also identifies which facilities consistently run behind schedule, informing future scheduling buffers. If a facility consistently exceeds grace periods, raise it directly with the warehouse's operations contact with documented wait-time data — appointment systems are sometimes overbooked relative to dock capacity, and consistent data can support a request for adjusted slot allocation.
