How to Read an LTL Freight Invoice: Accessorial Charges Explained

You quoted a shipment at $312. The invoice came back at $487. Nothing about the freight changed, so where did the extra money go? In almost every case like this, the answer is LTL accessorial charges: the add-on fees carriers bill for services beyond a standard dock-to-dock move.

At McClain & Associates, we have been managing freight for St. Louis area shippers since 1995, and invoice questions come up in nearly every new conversation. This walkthrough covers the anatomy of an LTL invoice, the most common accessorials, why invoices rarely match quotes, and how to push back when a charge is wrong.

The Anatomy of an LTL Freight Invoice

Every carrier formats invoices a little differently, but the math underneath is the same. Four line items do most of the work.

• Base rate. The carrier's published tariff rate for your lane, weight, and freight class. Published rates are intentionally high, which is why the next line matters so much.
• Discount. A percentage off the base rate, negotiated by you or by your 3PL. Discounts of 70 percent or more are common, which sounds generous until you remember the base rate was inflated to begin with.
• Fuel surcharge (FSC). A percentage added to the discounted rate, tied to the national diesel index. It floats week to week, so the same lane can price differently on Monday than it did the previous Friday.
• Accessorials. Everything else. Liftgates, residential stops, reweighs, detention. This is the section that turns a $312 quote into a $487 invoice.

Read the invoice in that order every time. Base, discount, fuel, then accessorials. If the total looks wrong, the problem almost always lives in line four.

The Most Common LTL Accessorial Charges, Explained

Here are the fees Midwest shippers see most often, what triggers them, and what they typically look like in dollar terms. Treat the ranges as ballpark figures only, since every carrier tariff is different.

Liftgate service

Charged when the pickup or delivery location has no dock and the driver needs a hydraulic liftgate to get freight to the ground. Often $50 to $150 or more per stop. If your customer's receiving area is a storefront or a jobsite, assume a liftgate is needed.

Residential delivery

Applied when the delivery address is a home or a business operating out of one. Carriers define "residential" by the character of the neighborhood, not your intent, so a woodshop in a converted garage in St. Charles still counts. Usually $50 to $200.

Limited access

Covers locations that slow the driver down: schools, churches, military bases, construction sites, storage facilities, some rural farms. Often overlaps with residential fees on the same invoice, and often billed in a similar range.

Inside delivery

The driver moves freight beyond the immediate delivery point, through a door, down a hallway, or to a specific room. This can run from $50 to several hundred dollars depending on labor time. Never assume it is included.

Reweigh and reclassification

The carrier scales or inspects your freight and decides the weight or freight class on the bill of lading was wrong. The invoice is then rebilled at the corrected figures, plus an inspection fee. These are the most disputed accessorials in LTL, and the most preventable.

Detention

The clock starts when a driver waits at your dock beyond the free time in the tariff, often 15 to 30 minutes. After that, you pay for the driver's time in increments. A slow forklift operator can cost real money.

Redelivery

Nobody was available, the paperwork was wrong, or the receiver refused the freight, so the carrier has to come back. You pay for the second attempt, and sometimes storage in between.

Why Your Invoice Rarely Matches Your Quote

An LTL quote is an estimate built on the information you entered: weight, dimensions, class, and service needs. The invoice reflects what the carrier actually encountered. Any gap between the two becomes a charge.

The usual culprits are simple. The pallet weighed 1,140 pounds, not the 1,000 on the BOL. The commodity was classed at 85 when the carrier's inspection said 125. Nobody mentioned the delivery was a clinic with no dock. Fuel moved between quote date and ship date.

None of this means the carrier is cheating you. It does mean every invoice deserves a look before it gets paid, which is exactly what a freight management partner in St. Louis is set up to do at scale.

How to Dispute an LTL Accessorial Charge

Carriers reverse incorrect charges regularly, but only when the shipper does the work. Here is the process that gets results.

1. Act fast. Most carriers cap disputes at 30 to 90 days from the invoice date. A charge you sit on is a charge you own.
2. Pull your paperwork. The BOL, the delivery receipt, the original quote, and any photos of the shipment on the scale or shrink-wrapped on the pallet.
3. Check the trigger. For a reweigh, compare the carrier's certified scale ticket to your own scale records. For a liftgate or residential fee, confirm what the delivery site actually is.
4. File in writing through the carrier's dispute portal or your 3PL. Include the pro number, the specific charge, and your evidence. Vague complaints go nowhere.
5. Track it to resolution. Disputes can take weeks. Keep a log so credits actually land.

If that sounds like a part-time job, it is. This is one reason smaller shippers around St. Louis hand invoice review to a third party.

Preventing Accessorials With a Better Bill of Lading

The cheapest accessorial is the one that never gets billed. Most prevention happens before the truck arrives, on the BOL and in your quoting habits.

• Weigh and measure every shipment on a calibrated scale. Guessing invites reweighs.
• Confirm the correct NMFC number and freight class for each commodity, and revisit them when packaging changes.
• Ask your customer about their receiving situation: dock or no dock, business hours, appointment requirements, anything unusual about the site.
• Note every needed service on the quote and the BOL, so the liftgate you knew about is billed at the quoted rate instead of the tariff rate.
• Keep your dock crew ready at pickup time to stay ahead of detention.

Shippers moving freight between Chicago, Kansas City, and St. Louis deal with these issues constantly, and lane knowledge helps.

Where a Freight Invoice Audit Fits In

A freight invoice audit is a systematic review of every invoice against the quote, the contract tariff, and the shipping documents before payment goes out. Done consistently, it catches duplicate billings, misapplied discounts, wrong fuel percentages, and accessorials that do not match reality.

Most small and mid-size shippers do not have a person to spare for this. A 3PL does. At our Maryland Heights office, invoice review is built into how we manage LTL freight for St. Louis area manufacturers, distributors, and wholesalers. We quote the shipment correctly up front, audit the invoice on the back end, and handle disputes with carriers we work with every day.

That combination matters more than any single tactic. Accurate BOLs shrink the number of surprises, and the audit catches whatever slips through. Together they turn LTL shipping costs from a monthly mystery into a number you can actually budget.

Frequently Asked Questions

What are LTL accessorial charges?

LTL accessorial charges are fees carriers add for services beyond a standard dock-to-dock shipment. Common examples include liftgate service, residential delivery, limited access locations, inside delivery, reweighs, detention, and redelivery. They appear as separate line items on the freight invoice and are the most common reason an invoice exceeds the original quote.

Why is my LTL invoice higher than my quote?

Your invoice is higher because the carrier encountered something the quote did not include. The most frequent causes are inaccurate weight or freight class on the bill of lading, unlisted services like a liftgate, delivery sites classified as residential or limited access, and fuel surcharge changes between the quote date and the ship date.

How do I dispute an accessorial charge on a freight invoice?

File a written dispute with the carrier, usually within 30 to 90 days of the invoice date. Include the pro number, the specific charge, and supporting evidence such as the bill of lading, certified scale tickets, delivery receipts, or photos. Carriers regularly reverse charges when documentation shows the fee was applied in error.

How can I avoid reweigh and reclassification fees?

Weigh every shipment on a calibrated scale, measure its true dimensions, and list the correct NMFC number and freight class on the bill of lading. Keep scale records as proof. Most reweigh fees trace back to estimated weights or outdated class assignments, so accurate documentation prevents the charge and wins the dispute if one occurs.

What is a freight invoice audit?

A freight invoice audit is a line-by-line review of carrier invoices against quotes, contract tariffs, and shipping documents before payment. It catches misapplied discounts, incorrect fuel surcharges, duplicate billings, and invalid accessorial charges. Many St. Louis shippers have a 3PL perform audits, since 3PLs review carrier invoices daily and know each tariff's rules.
