Accessorial charges need an explanation before they need a payment.
Key Takeaways
Every accessorial should answer four questions before it's paid: was the service requested, did it happen, is the amount right under the carrier's agreed terms, and who has authority to approve it.
Unexplained accessorials get paid because the person paying the invoice doesn't have the booking. Accounts payable sees a carrier, an amount and a due date, not the rate confirmation or the delivery record.
Approval should follow context and authority: planned charges pass with the invoice, unplanned but documented charges go to logistics within a limit, and undocumented charges are held and questioned.
Wilson, by Cartage, is an AI logistics agent that audits each carrier invoice against the booking and, under the approval rules the company sets, holds charges that weren't on the booking for a person before paying the carrier.
Most accessorials are cheaper to prevent than to dispute. Requesting known services with the quote removes the surprise from the invoice.
Why do accessorial charges get paid without an explanation?
Accessorials get paid without an explanation because the invoice reaches someone who has the payment authority but not the shipment record. Without the booking, the timestamps and the carrier's terms in front of them, the only safe-looking choice is to pay on time. An accessorial should be explained, by the carrier and by the record, before it's approved.
An accessorial is any charge for a service beyond standard pickup and delivery: liftgate, appointment, inside delivery, residential delivery, detention or redelivery. These charges hit manufacturers and distributors hardest on LTL freight and on deliveries to retail and job-site consignees. Detention alone is common: ATRI found truck drivers were detained at 39.3% of stops in 2023, with $3.6 billion in direct costs.
Here is how one invoice gets paid.
Monday 11:00 a.m. The coordinator books an LTL load. The rate confirmation (the document recording the agreed price and terms) lists linehaul and fuel only.
Wednesday 2:10 p.m. The driver arrives at the consignee. Receiving is backed up; the truck waits. The coordinator never hears about it.
Wednesday 4:30 p.m. The load delivers. The POD (proof of delivery: the signed delivery receipt) shows the date but no arrival or departure times.
Three weeks later, Tuesday 9:15 a.m. The accounts payable clerk opens the invoice: linehaul, fuel and, for example, $175 in detention. She doesn't know whether the truck was held, for how long or what the carrier's free time is.
Tuesday 9:20 a.m. She emails logistics. The coordinator is handling two missed pickups. The invoice is due Friday.
Friday 3:00 p.m. It gets paid, unexplained.
The charge may have been valid. The problem is that nobody could say.
What should you check before paying an accessorial?
Check four things: was the service requested, did it happen, is the amount right, and who approves it. The first three need evidence; the fourth needs a rule.
Was it requested? Look at the booking and the rate confirmation. A liftgate requested at booking is planned. One that wasn’t is unplanned until explained.
Did it happen? Look for the record: timestamps, the BOL (bill of lading: the shipping document the driver signs at pickup) notes, the POD, the carrier’s delivery attempt log.
Is the amount right? Compare with the carrier’s agreed accessorial terms, not with what seems reasonable.
Who approves it? Apply the company’s approval rules for unplanned charges.
The evidence differs by charge, and it usually lives with logistics, not with accounts payable.
Accessorial | Evidence that it happened | Who usually has it |
|---|---|---|
Liftgate | Booking request, or consignee delivery requirements | Logistics, customer service |
Appointment | Appointment confirmation with date and time | Logistics |
Detention | Arrival and departure times, carrier’s free time terms | Carrier, logistics |
Redelivery | First attempt record and reason | Carrier |
Inside or residential delivery | Delivery address type, consignee instructions | Customer service |
If the evidence isn’t on the shipment record, ask the carrier for it before approving. A legitimate charge usually comes with a reason the carrier can document. For how missing services skew quotes in the first place, see the cheapest freight quote often leaves out the expensive part.
Who should approve accessorial charges?
Whoever has both the context and the authority: logistics for unplanned charges within a limit, a manager above it, and nobody for charges the carrier can’t document until they’re explained. Accounts payable should pay what’s been approved, not decide what’s valid.
Situation | Who decides | What happens to the payment |
|---|---|---|
Charge was on the booking | No one; it’s planned | Paid with the invoice |
Unplanned, documented, within the limit | Logistics | Paid once approved |
Unplanned, documented, above the limit | The person with that authority | Waits for approval |
Unplanned and undocumented | Logistics, with the carrier | Held until explained or corrected |
Set the limits per charge type if your lanes justify it. For example, a team might let appointment fees pass with a logistics approval but route every detention charge above a set amount to a manager, because detention is the charge most often billed without timestamps. For where the hold should sit in the payment process, see the invoice doesn’t match the quote. Who stops the payment?
Common mistakes
Paying to protect the due date. The charge becomes the precedent, and the carrier has no reason to document the next one.
Disputing without evidence. If your own record has no timestamps, the carrier’s word stands and the dispute costs time for nothing.
Approving accessorials in a batch at month end. By then, nobody remembers the load, and the evidence is buried in an inbox.
Never feeding findings back to booking. The same consignee triggers the same liftgate charge every week because nobody adds it to the order.
How does Wilson, by Cartage, handle accessorial charges?
Wilson audits each invoice against what was booked, separates charges that were on the booking from those that weren’t, and holds charges that need approval under the company’s rules before paying the carrier from the preloaded wallet. Traditional logistics software gives teams information. Wilson executes the work required to move shipments forward.
Wilson runs the load from quote to payment, so the booking, the rate confirmation, the carrier’s messages, the POD and the invoice are on the same shipment record. The person approving a charge sees the load, not just an amount.
Step | Trigger | What Wilson does | When a person steps in |
|---|---|---|---|
1. Quote | Order becomes a shipment | Requests quotes from approved carriers for the load as described | Not required |
2. Book | Carrier accepts | Records the rate and sends the rate confirmation | Booking above the approval limit |
3. Deliver | Load delivers | Requests the POD, follows up until received and files it | If the POD is missing past the set window |
4. Audit | Invoice arrives | Checks every line against what was booked | Not required |
5. Hold | A charge wasn’t on the booking and the rules require approval | Holds it and puts the shipment record in front of the approver | Approving or disputing |
6. Reconcile | Charge is approved, corrected or disputed | Records the outcome on the shipment | Not required |
7. Pay | Invoice is audited and reconciled | Pays the carrier from the preloaded wallet | Payments above the approval limit |

Controls
The company decides which actions need a person, and it can set approvals on any of them: unplanned charges, payments above a threshold, carrier selections. Wilson starts with assisted execution and widens what runs automatically step by step as trust builds. A charge inside the rules proceeds; a charge outside them waits.
Wilson escalates when a decision exceeds the approval rules or a difference can’t be resolved with the carrier. Every message, confirmation and change on each shipment is recorded in a change history, and call transcripts are saved on the order, so finance can see why a charge was approved. Wilson pays only after an invoice is audited and reconciled, books only approved carriers and does not manage dock slots inside your facility, so detention caused at your own dock still needs a fix on your side.
What should you ask a vendor to show in a demo?
Ask the vendor to take one of your invoices with an accessorial nobody could explain and show, step by step, how it would have been checked, approved or held, and paid. If the answer starts at the invoice, the booking side is still manual.
Show the booking and rate confirmation next to the invoice, on the same record.
Show how a planned accessorial passes and an unplanned one stops.
Show who gets the hold, what they see and how they approve or dispute it.
Show detention evidence: where arrival, departure or call records sit for that load.
Show the payment and the change history behind it.
To measure the change, compare the lanes the new process runs with how they ran before: unplanned accessorials per load, how many were paid without an approval, and the share disputed with evidence. For how an agent fits into the wider workflow, see what is an AI logistics agent.
FAQs
Should I pay accessorial charges I didn't approve? Not before checking them. Confirm the service was requested or documented, that it happened and that the amount matches the carrier's terms, and hold anything unexplained.
What are accessorial charges in freight? Charges for services beyond standard pickup and delivery, such as liftgate, appointment, inside delivery, detention or redelivery.
Who should approve accessorial charges? Whoever has the context and the authority under the company's approval rules: usually logistics within a limit and a manager above it. Accounts payable should pay what's approved, not judge what's valid.
What evidence do I need to dispute detention? Arrival and departure times and the carrier's free time terms. Without timestamps on your side, the carrier's record usually stands.
Does Wilson check accessorial charges? Yes. Wilson audits each invoice against what was booked and, under the company's approval rules, holds charges that weren't on the booking for a person before paying.
Does Wilson pay carriers? Yes. The company preloads a wallet, and once a carrier's invoice is audited and reconciled, Wilson pays the carrier from it.
How is Wilson priced? There's no subscription fee. Pricing is a percentage of the carrier payments that run through Wilson, and that one fee covers the full shipment lifecycle: create, quote, tender, track, audit and pay.
Conclusion
An accessorial without an explanation is a charge nobody checked. The four questions take minutes when the booking, the delivery record and the carrier's terms are in one place, and they take days when they're spread across logistics, the carrier and accounts payable. Put the approval with whoever has the context, and hold what nobody can explain.
Wilson, by Cartage, keeps the booking and the invoice on the same record, audits every line, holds unplanned charges for the person your rules name and pays only after the invoice checks out. Bring one invoice with an accessorial your team couldn't explain and watch Wilson audit it against the booking in a demo at cartage.ai.
