"Since we connected our tools, we stopped losing track of detention charges that never made it onto the invoice. The AI pulls from our actual rate cons and load notes, so nothing falls through the cracks the way it used to.", director of operations at a regional freight brokerage
Most small freight brokerages throw away thousands of dollars per month in lost revenue by never billing, disputing or collecting for accessorial charges.
Where the revenue leakage for small freight brokers actually starts
Accessorial charges are supposed to be straightforward. A driver waits two hours at a dock. Liftgate service required. A residential delivery. A broker records the accessorial charges. The broker bills for them and the broker collects for them. It is not that simple in reality.
Additional charges are documented in a driver’s text, included in a Slack message from the dispatcher, or included in a PDF that is emailed to the carrier. However, by the time the invoice is generated and sent to the carrier for billing, the additional charge has been forgotten.
The type of leakage seen in small 3PL’s is viewed as normal part of the operating pressures of the company. As the margins are thin already and operations are already highly pressured the “invisible” leakage is often left nameless month after month. There is not enough time to run a full audit on every load.
Which accessorial charges freight brokers miss most often
All accessorials don’t decline at the same rate. Some are included in rate confirmation and therefore are captured upfront while others rarely get charged and are never invoiced out to customer.
Detention and layover charges – These are the worst kind of charge. They are usually added after the fact by the dispatcher as a note to the driver or in a check call. They are very difficult to add to the bills if there is no process in place to pull notes from the driver’s notes in the system.
Liftgate charges are often left off because the proper liftgate equipment need was not identified until after rate had been confirmed with shipper. Even though liftgate was used, billing team never sees update to add on liftgate charge.
Residential delivery fees are being dropped when stop type changes between time of booking and time of delivery. This is same problem as above. Rate con contains information that was entered at time of booking; actual delivery does not reflect this.
Fuel Surcharge corrections: Fuel Surcharge corrections are another category of corrections. As a rule Fuel Surcharge corrections are updated by the Carrier on the invoice and the broker pays the invoice without auditing for the corrections. These corrections are lost on the customer invoice.
Why freight broker accessorial invoice disputes are so hard to win without documentation
Raising a dispute is easy. Winning one is not.
In detentions for Brokerage Disputes, it is typical for Carriers to require Brokerage to supply backup documentation for the dispute. This would include a time stamped delivery confirmation, signed BOL that lists time of arrival and time of departure, or a driver’s log. Without the above mentioned documentation a dispute will be ignored by Carrier or disputed by their records and Brokerage will lose because they have no proof to support their dispute.
Laneproof data shows that brokerages auditing accessorial line items systematically report recovering 2 to 5 percent of total carrier spend, with dispute win rates between 60 and 74 percent when proper documentation is attached. Documentation is not a formality, it is the mechanism.
All the documentation for a small 3PL exists somewhere – a screenshot from a driver’s app, an email or even a Slack thread. However, in a small 3PL, the documentation is not organized to associate it with a specific load at the time of billing. Thus the dispute never gets filed or it gets filed but without the attachment that would make it stick.
Most of the tools were built for an operations team with established processes around current tools. That just doesn’t scale for a small brokerage.
How small 3PLs can build a system that catches missed accessorials before they disappear
More software is not the answer. Clean information hygiene on the data you have already is the answer.
Enforce at the point of booking. The detailed schedules for accessorial charges as outlined above should be included in the rate confirmations. Detention for example starts after 2 hours and then outlines how that is charged. Liftgate charges should outline when these additional charges are required and the Residential Surcharge charges should outline when this is to be applied. If these conditions are not included in the rate confirmation then they cannot be enforced later.
Standardize how field information is collected and fed to the billing team. The accessorial information that is typically collected and noted by drivers, from check calls with shippers or consignees, and from emails from shippers or consignees to the carrier and its billing team, should consistently be routed to the same team member who is processing the associated bill. This information could be routed via a shared inbox, via check calls that follow a template, or via handoffs from the dispatcher(s) to the billing team. There must be a process that connects all of this information.
Dispute Documenting IMMEDIATELY with attachments. The Dispute should be filed the same day the problem is discovered. Supporting documentation for the Dispute would include rate con, BOL, any correspondence with the driver as well as a written summary of the problem. Don’t wait as the evidence will decay and can be used against the disputant to prove that the carrier has acted with due diligence and that they were NOT negligent in allowing the delay to occur.
You don’t have to buy an enterprise TMS to put these practices into place. Simply executing on the data your operation already is generating is all that is required.
What LemonLime does for freight brokers dealing with accessorial invoice leakage
A big problem that we see with the different tools that businesses use to run their day to day is that they don’t all integrate. So, for example, you might have rate confirmations in one place and communication with your drivers in another system. You might have invoices from carriers in PDF format, and payment history from your QuickBooks accounting software in another system. Nobody has a complete picture of how to bill in a given situation.
LemonLime simply logs into all the tools that your business already uses (e.g. your accounting package, such as QuickBooks, your productivity software, like Google Workspace, your team collaboration software, like Slack, your email, etc.). All the data that is scattered throughout your business’s many “operational systems” is then automatically ingested into the AI powered accounting system and structured into a knowledge layer on top, which is optimized for both AI powered retrieval and for AI powered reasoning. That knowledge layer automatically updates and grows in value as more data and more documents are added to the system.
That could be really powerful for freight brokerage, specifically around disputes for accessorial invoices. The AI could find the disparity before the window to dispute closes by stitching together the Rate Con, the driver log, the carrier’s invoice and what actually got paid. Not have someone search for it. The system is set up to look at all of that information as a whole.
LemonLime is an unusual tool for the 3PL and freight brokerage markets because it doesn’t create a new way for small 3PLs and freight brokerages to lose accessorial revenue through disparate tools, and then write off disputes that could have been prevented. It is currently on waitlist at lemonlime.ai.
Frequently asked questions about freight broker accessorial invoice disputes
Why are my freight broker accessorial charges so hard to track after the load delivers?
The information needed to charge an accessorial is typically outside of your billing system. Information such as driver notation, carrier emails, check-call logs and signed BOL’s create evidence needed for accessorial charges. However, the link between the charge and the documentation that supports the charge typically does not exist at the time the invoice is being billed. The charge exists; the documentation exists; the connection between them does not. This is where the revenue goes.
How do I know if my brokerage is losing money on missed accessorial billings?
Select 50 different loads from the last 2 months of activity. For each of the selected loads, compare the Accessorial Charges listed on the customer’s final invoice with the related information found on the delivery documentation for the load (i.e. detention time, liftgate usage, etc.). If you find more than a few discrepancies between what was charged to the customer and what occurred for the load then you have found either a system leak or an isolated error rather than an isolated incident.
What documentation do I need to win a carrier accessorial dispute?
At minimum: the original rate confirmation with the accessorial schedule, the signed BOL with arrival and departure timestamps, any driver or dispatcher communication confirming the charge trigger, and a written summary of the variance you are disputing. This would include the original rate confirmation that includes all accessorial charges plus a copy of the signed BOL that lists the carrier uses to include the dates and times for pickup and delivery plus any documentation from the driver and/or dispatcher that supports the rate charged by the carrier plus a brief written description of the variance from contracted rates that the shipper is contesting. Disputes filed with all four win at meaningfully higher rates than disputes filed without them. This documentation turns a shipper’s complaint into a real claim that a carrier is required to respond to.
How long do I have to dispute a carrier accessorial charge?
Dispute windows vary by carrier and contract, but most fall between 30 and 180 days from invoice date. This time frame varies by carrier and by contract, but is typically between 30-180 days from the invoice date. It is generally in both parties best interest to contest a bill as early as possible in the dispute window. The evidence will be more complete, the facts will be fresher and it is less likely that the carrier will consider a delay in filing as acceptance of the terms and conditions of the contract. It is best to add the Dispute Process to your normal monthly billing audit to ensure all disputes are identified and contested before they expire.
Can a small brokerage realistically audit every invoice for accessorial discrepancies?
This can be a systematic process rather than a line-by-line manual audit of every single invoice. Flag up the invoices where the carrier-billed accessorials do not equate to what had been confirmed within the rate confirmation and then send those on a case-by-case basis to a human to check. This is a document-matching problem, not a subject matter expertise problem. This is something that can be solved by structured data and AI powered document retrieval.
Will disputing carrier invoices damage my carrier relationships?
- Filed correctly, no. Disputes are a normal part of the business relationship that a carrier has with a shipper. A dispute with proper documentation filed in a timely manner is part of doing business. Disputes without evidence to support them, filed late, or filed in high volume without selectivity can do a lot of harm to a relationship. If you’re winning 60% plus of your disputes then they must be well-founded. Below 60% then one needs to take a hard look at the documentation that they are using to support the dispute that they’re filing.

Frequently Asked Questions
Why do I keep missing detention charges on my freight broker invoices?
Detention charges are missed because the trigger — a driver waiting two hours at a dock — gets recorded in a text, a Slack message, or a check-call note that never makes it to your billing team before the invoice goes out. By the time someone looks, the connection between the charge and the documentation supporting it is gone. LemonLime ingests your rate confirmations, driver correspondence, and Slack threads into one knowledge layer so detention triggers get flagged before the invoice closes.
How much money could my small 3PL actually be losing from unbilled accessorials every month?
More than most operators realize. Brokerages that audit accessorial line items systematically report recovering 2–5% of total carrier spend — and that's recurring, month after month. For a small 3PL, that adds up to thousands of dollars in avoidable revenue leakage. The article recommends pulling 50 recent loads and comparing customer invoices against delivery documentation. If you find more than a few gaps, it's a system problem, not an isolated error. LemonLime is built to close that gap automatically.
What's the fastest way for me to build a freight accessorial dispute process without buying a full TMS?
You don't need a new TMS — you need cleaner connections between the data you're already generating. Start by embedding your accessorial schedule directly into every rate confirmation, standardize how field information flows to your billing team, and file disputes the same day you identify a discrepancy with all supporting documentation attached. LemonLime connects to tools you already use — QuickBooks, email, Google Workspace, Slack — and structures that data into a knowledge layer that surfaces discrepancies before the dispute window closes.
Does disputing carrier invoices hurt my carrier relationships as a small freight broker?
Filed correctly, no — disputes are a normal part of the carrier-broker relationship. The damage comes from disputes filed late, without documentation, or in high volume without selectivity. If you're winning 60% or more of your disputes, they're well-founded. Below that, your documentation process needs work. LemonLime helps you file disputes with the rate confirmation, BOL timestamps, and driver correspondence already attached, which means fewer disputes overall and stronger ones when you do file.
Can AI actually help me catch missed liftgate or residential delivery fees before I send the customer invoice?
Yes — and this is exactly the type of document-matching problem AI handles well. Liftgate and residential fees are most often missed because the stop conditions changed after booking and the billing team never saw the update. AI can cross-reference your rate confirmation against the BOL, driver notes, and carrier invoice to flag the discrepancy automatically. LemonLime does this by building a structured knowledge layer from your existing tools, so nothing requires a manual line-by-line audit to catch.
