Someone in our industry is always saying freight margins are getting tighter. They’re not wrong, but the part we rarely say out loud is this: it’s not always the linehaul that kills the load. It’s the pile of small, messy charges that show up a week later and quietly erase the profit.

If you’ve had a month where volume looked good but gross profit somehow didn’t, you already know where this is going. Detention. Layover. TONU. Driver assist. Re-delivery. Residential. Limited access. Chassis split. Storage. And the worst one of all: “Other”.

Accessorials aren’t random. They’re predictable chaos.

What’s broken is the way accessorials get created, communicated, and verified across the chain.

We run freight in a world where the shipper’s appointment lives in an email thread, the broker’s rate confirmation lives in a PDF, the carrier’s proof lives in a driver’s photo roll, and the warehouse’s reality lives on a whiteboard. Then we act surprised when the invoice doesn’t match.

Here’s why it keeps happening:

• The first version of the truth gets typed manually. A CSR keys an appointment time into the TMS from a customer email. One typo, one timezone mistake, or one missed update, and we’ve just manufactured detention.
• “Free time” is rarely enforced consistently. A contract might say 2 hours free, but if we don’t track check-in and check-out times, we can’t push back on inflated claims.
• Warehouse constraints are invisible until the driver is stuck. Floor congestion, labor gaps, late inbound trailers, and yard moves all turn into detention. But we only see it when the bill arrives.
• Accessorial rules are different per customer, per lane, per facility. The team is expected to remember which DC requires an ELD screenshot, which one accepts a signed BOL time stamp, and which one always disputes.
• Disputes take too long. If we challenge a charge 12 days later without clean proof, we lose. Most shippers and brokers have dispute windows and they’re not generous.

This isn’t a “people need to work harder” issue. It’s an information flow issue.

The numbers are getting uglier, not better

Industry-wide, accessorials are becoming a larger share of total freight spend, especially in messy networks: multi-stop, retail compliance, port drayage, and appointment-heavy food and beverage.

A few shifts are driving that:

• Tighter dock schedules and fewer labor buffers. Warehouses are running lean, and when labor gets tight, truck turn times slip.
• More appointment sensitivity. Retail and high-volume DCs are enforcing appointment windows more strictly, which increases re-delivery, layover, and reschedule fees.
• Higher compliance expectations. Shippers want cleaner ETAs, tighter OTIF, and better documentation. That’s fair, but it means paperwork and timestamps matter more.
• A bigger spotlight on detention. There’s more public pressure to reduce driver dwell time, and carriers are pushing harder to get paid for it.

In practical terms, we see the same pattern: one detention charge might be $150 to $300. That doesn’t sound fatal until it happens 30 times in a month. Now you’re staring at $4,500 to $9,000 in unplanned cost, plus the hours your team spent arguing about it.

We can’t eliminate accessorials, but we can stop being surprised by them

The path forward isn’t complicated, but it does require operational discipline.

Start with one goal: make accessorials measurable and defensible.

1) Standardize what “proof” means, by charge type

Write a simple one-page policy that answers:

• What counts as detention proof? (Example: ELD arrival/departure + facility check-in/out timestamp or signed BOL with times.)
• What’s required for TONU? (Example: email or portal confirmation of tender acceptance + arrival proof.)
• What’s required for lumper/driver assist? (Example: receipt photo + notation on POD.)

Then train dispatch, billing, and ops on it. If proof isn’t collected within 24 hours, assume it will be disputed.

2) Track dwell like it’s a KPI, not an exception

Most teams only talk about detention after it hits billing. Flip it. Track dwell time at the top 10 facilities every week.

If a DC averages 3.5 hours and your contract assumes 2 hours free, you don’t have a carrier problem. You have a facility reality problem. That changes how we price, schedule, and communicate.

3) Put accessorial expectations into the rate confirmation and tender

A lot of accessorial fights happen because terms were implied, not written. Make it boring and explicit:

• Free time policy and when the clock starts
• Required documentation
• Max amounts or pre-approval requirements (where applicable)

This doesn’t stop everything, but it reduces the “we never agreed to that” loop.

4) Fix the feedback loop between warehouse and transportation

If our WMS knows the dock is backed up, transportation should know before the driver arrives. If our TMS sees a driver checked in 45 minutes early, the warehouse should know so they can pull the order sooner.

Even a simple daily 15-minute call between warehouse leads and dispatch can cut repeat detention. Not once. Repeatedly.

If you want to tighten this further, tools like Debales.ai can help by turning messy freight emails and documents into structured data and flagging accessorial risk before it becomes a charge.

What we can do this week (without a “transformation” project)

Here are five moves that don’t require new headcount:

• Build a “top 20 accessorials” report from the last 60 days. Sort by dollars and frequency. If you can’t pull it from your TMS, export invoices and categorize manually once. Painful, but worth it.
• Pick the worst three facilities and call them. Not to complain. To align. Ask: What’s your current average unload time? When are your labor pinch points? What appointment windows are actually realistic?
• Implement a 24-hour documentation rule. Drivers or carriers send ELD screenshots, POD, lumper receipts, and check-in/out proof within 24 hours or we treat it as non-billable unless approved.
• Pre-authorize the common ones. If we know a lane regularly triggers driver assist, bake it into the rate or add a standard accessorial line item. Predictable cost beats surprise cost.
• Create a one-screen checklist for dispatch. Before confirming an appointment: appointment time, FCFS vs scheduled, required equipment, special instructions, and who pays for lumper. If it’s not captured, it will become an accessorial later.

None of this is glamorous. But it’s how we stop losing money in small increments.

Accessorials are often treated like the weather. Unavoidable. Nobody’s fault. The truth is harsher and more useful: accessorials are the bill for operational ambiguity. The clearer we get, the less we pay.
