Detention and Layover Documentation for Freight Brokers: Evidence That Reduces Disputes

Detention and layover documentation is not just an accounting task. It is the evidence trail that shows whether the carrier was on time, available for service, delayed by the shipper or receiver, and entitled to an accessorial under the agreed terms.

When the file is weak, operations spends hours chasing gate times, accounting short-pays the carrier, and customer reps argue from memory. Authority status and insurance files do not prove detention. The load timeline does.

Quick answer: what a good file includes

A usable detention or layover file should show five facts:

• The appointment time and location
• The carrier’s arrival and check-in time
• What caused the delay
• When the driver was released or held to the next day
• Who approved the charge and under which terms

Common broker-carrier schedules use 2 free hours, then $50 to $100 per hour for detention, with dry van layover often in the $250 to $500 range. Refrigerated, specialized, high-value, and auto transport work can run higher. The exact amount depends on the rate confirmation, customer contract, tariff, or written approval.

Why detention and layover documentation matters

Most accessorial disputes break at one of three points:

1. No clean appointment record
2. No reliable check-in or check-out time
3. No written approval tying the charge to the rate confirmation or customer terms

A carrier text that says delayed 6 hours is not the same as a file showing an 08:00 appointment, 07:42 gate check-in, no dock assignment until 11:18, loading complete at 14:06, and customer notice sent at 10:05.

The difference is not paperwork volume. It is whether the evidence connects the charge to the actual service failure.

Documentation strength scale

Use this scale before approving the carrier charge or billing the customer. A score 2 file may justify more follow-up. A score 5 file is ready for accounting review.

Detention and layover documentation workflow

1. Set the accessorial rules before dispatch

The rate confirmation should state the accessorial terms clearly enough for a dispatcher to apply them without guessing:

• Free time: usually 2 hours, but confirm by customer and lane
• Hourly detention rate and any daily cap
• Layover trigger: held to next business day, missed facility window, or other defined event
• Notice requirement: carrier must notify within a set time, often at arrival and before free time expires
• Required evidence: gate ticket, timestamped message, facility contact, POD, BOL, or GPS record

If the customer contract uses different terms than the carrier rate confirmation, flag it before tender. Otherwise, the broker may approve an amount the customer will not reimburse.

2. Preserve the appointment record

For every pickup or delivery appointment, save:

• Appointment date, time zone, and facility address
• Appointment number or portal confirmation
• Original appointment and revised appointment, if changed
• Person or system that changed it
• Timestamp of the change
• Reason for the change: shipper delay, receiver capacity, carrier late, weather, production issue, missed cutoff

A phone call is acceptable operationally, but the file should contain a same-day note: who called, at what time, what changed, and who approved it.

3. Capture arrival within 15 minutes

Ask the carrier for arrival proof as soon as the driver reaches the facility:

• Check-in time
• Gate, dock, or yard location
• Name or description of the person receiving check-in
• Trailer number, VIN, or unit number when relevant
• Timestamped GPS or ELD location if available
• Photo of gate sign if the facility refuses written check-in

Do not start the clock from ETA unless the written terms say ETA controls. Most disputes turn on appointment time, actual arrival, and facility check-in.

4. Build the delay timeline during the hold

If the driver is still waiting after free time, record updates every 90 to 120 minutes. Each update should answer:

• Is the driver in line, checked in, docked, loaded, unloaded, or waiting on paperwork?
• Has the facility given a reason?
• Has the customer been notified?
• Is a revised pickup or delivery appointment needed?
• Is the driver at risk of hours-of-service impact?

Broker note: the best accessorial files are built while the load is live. After delivery, gate logs are harder to get, facility contacts forget details, and screenshots lose context.

5. Separate detention from layover

Detention usually covers waiting time beyond free time on the same service event. Layover usually applies when the driver cannot complete pickup or delivery and is held to a later date or next facility window.

For layover, capture:

• Time the driver was released or told to return
• Facility closing time, missed cutoff, or refusal reason
• Next confirmed appointment time
• Written instruction from customer, shipper, receiver, or facility if available
• Whether the trailer was loaded, empty, sealed, or rejected

Do not convert detention to layover by habit. Use the terms in the rate confirmation or customer agreement.

Practical examples

Strong note:

• Load 28411. Delivery appointment 08:00 CT at Dallas receiver. Driver checked in 07:42 CT, gate 3, guard Maria R. Not docked at 10:05. CSR emailed customer at 10:08. Receiver assigned door 12 at 11:18. Empty at 14:06. POD signed 14:14. Detention requested: 4.25 hours after 2 free hours at $75 per hour. Revised rate confirmation sent 16:20.

Weak note:

• Driver waited 6 hours. Add detention.

The weak note may be true, but it does not give accounting, the customer, or management enough to review the charge.

Approval checklist before billing or paying

• [ ] Original rate confirmation includes detention or layover terms
• [ ] Appointment confirmation is saved
• [ ] Arrival and check-in time are documented
• [ ] Free time calculation is shown
• [ ] Delay updates were sent during the event
• [ ] Facility or customer reason is recorded when available
• [ ] Check-out, release, POD, or BOL time is saved
• [ ] Layover has next-day or next-window support
• [ ] Revised rate confirmation or written approval is attached
• [ ] Accounting can see the final approved amount and reason code

Common mistakes

• Starting detention at ETA instead of appointment or check-in time
• Losing the original appointment after a reschedule
• Accepting screenshots with no load number, time zone, or facility context
• Approving accessorials by text but never issuing a revised rate confirmation
• Treating customer approval and carrier evidence as the same thing
• Waiting until the carrier invoice arrives to build the file
• Applying one detention rule across all customers, equipment types, and commodities

Where Longmile fits naturally

Longmile can help broker teams keep the partner record, appointment changes, communication notes, exception history, and accessorial evidence in one review file instead of scattered across inboxes, TMS notes, screenshots, and personal phones. That matters when accounting, claims, and operations all need to understand the same timeline.

FAQ

Is a GPS screenshot enough for detention?

Usually not by itself. GPS can support location, but it does not prove appointment time, facility check-in, free time expiration, delay cause, or approval terms.

Should the broker require a revised rate confirmation?

Yes when the payable amount changes or when the original rate confirmation requires written approval. A revised rate confirmation reduces confusion between operations approval and accounting payment.

What if the facility refuses to provide gate times?

Record the refusal, save driver arrival proof, capture the facility contact or guard description, and notify the customer the same day. A same-day email is stronger than a note created after the invoice dispute.

When does detention become layover?

Use the written terms. Operationally, layover usually involves the driver being unable to complete service and being held to a later appointment or next business day.

Should brokers pay the carrier before the customer approves the accessorial?

That is a commercial policy decision. Keep the evidence review separate from customer reimbursement status so the team can decide consistently and document why.

Conclusion

Good detention and layover documentation is a load-execution discipline: define the rule, preserve the appointment, capture arrival, build the delay timeline, and attach approval before billing or payment review.

If your team is still reconstructing accessorials from texts and inbox searches, Longmile can help centralize the records that make those reviews faster and cleaner.
