Accessorial Claim Submission Deadlines: What Carriers Need to Know
Accessorial claim submission deadlines are the contractual windows — specified in the rate confirmation — within which carriers must submit detention, TONU, lumper, and other accessorial invoices or forfeit them. Most windows run 24–72 hours from delivery. Missing a window is one of the top three reasons legitimate detention claims go uncollected.
Why Submission Deadlines Exist
Submission deadlines exist in rate confirmations because brokers and shippers need to reconcile load costs within billing cycles. A detention claim that arrives 30 days after delivery, after the broker has already closed the load in their system, creates real administrative friction.
Whether that rationale justifies a 24-hour window is a separate question — what matters practically is that the window is in your contract and brokers enforce it. A claim submitted one day after the window closes can be legitimately rejected regardless of merit.
Typical Accessorial Submission Windows
| Accessorial Type | Common Window Range |
|---|---|
| Detention | 24–72 hours after delivery |
| TONU | Same day to 48 hours after cancellation |
| Lumper reimbursement | 24–72 hours after delivery |
| Layover | 24–72 hours after resuming service |
| Stop-off charge | With freight invoice |
| Liftgate | With freight invoice |
| Redelivery | 24–72 hours after second delivery attempt |
These are generalizations. Your specific window is whatever your rate confirmation specifies. Read it before every load.
How to Find Your Submission Window in the Rate Confirmation
The claim window is typically stated in one of two places:
In the detention/accessorial section:
“Detention must be submitted within 48 hours of delivery.”
In the billing terms section:
“All accessorial charges must be invoiced within 72 hours of load completion. Claims submitted after this window will not be honored.”
Some RCs combine both freight and accessorial billing terms: “All charges, including accessorials, must be submitted with the final invoice, due within [X] business days of delivery.”
If the RC says nothing about claim windows, submit within 24 hours anyway. The absence of a stated window doesn’t mean no window exists — a broker may argue “reasonable time” and you’ll be in a weaker position if you wait weeks.
What Happens When You Miss the Window
The Broker’s Position
A broker who receives a detention claim after the contractual window can legitimately deny it with: “This claim was submitted outside the window specified in the rate confirmation. We are unable to process this claim.”
This is a contract defense, not a moral one. The detention happened. The documentation may be solid. None of that matters after the window closes.
Your Counter-Options
Argue no window was specified. If the RC is truly silent on claim windows (not common but possible), you have an argument that a “reasonable time” standard applies and your submission was reasonable.
Request goodwill exception. Contact your broker account manager and explain the circumstances. First-time misses with documented reasons (system outage, staffing issue) sometimes get accommodated as a relationship matter. This is broker discretion, not your right.
Accept the loss and fix the process. A missed window is a sunk cost. The value is in identifying the process failure and preventing recurrence.
Building a Process That Never Misses a Window
Make the Window Part of Load Acceptance
When dispatch reviews a rate confirmation before accepting a load, the submission window should be logged alongside the delivery appointment. Treat the claim window deadline as a hard date that gets flagged to billing.
Submit Same Day as a Default Standard
The easiest way to never miss a claim window is to default to same-day submission for every detention event. Even if the RC allows 72 hours, building same-day submission as the standard eliminates all window risk.
This requires:
- Dispatch flagging detention at the time of the event (not waiting for the driver to report it days later)
- Billing receiving the flag same day
- GPS evidence being pulled and attached same day
If your operation runs Motive ELDs and you’re using manual processes, this is achievable but requires discipline. If you’re using an automated system like Dwell, the evidence is already built by the time billing reviews the queue.
Set a Deadline Alert for Every Pending Accessorial
For every load with a pending accessorial claim, a deadline alert should fire at least 24 hours before the window closes. This is the safety net for loads where same-day submission didn’t happen.
In a TMS, this is a custom alert on the accessorial field. In Dwell, it’s built into the detection and queue workflow automatically.
Tracking Window Compliance as a Metric
Add this to your monthly operations review:
| Metric | What It Tells You |
|---|---|
| % of accessorial claims submitted within window | Process discipline |
| $ forfeited due to missed windows | Revenue cost of process gaps |
| Average hours between delivery and submission | Where process time is going |
Most carriers who measure this find they’re submitting most claims within the window — but a consistent 5–10% miss rate compounds significantly across load volume. At 100 trucks with 470 detention events per month and $150 average claim, a 10% miss rate is $7,050/month in permanently forfeited revenue.
