A lumper fee is one of the few costs in brokerage that you pay before you can bill for it. And when the receipt does not come back, you do not bill for it at all. The money has already left through a payment code issued to the driver. Without a receipt, the shipper will not reimburse, and the fee quietly moves from "accessorial" to "margin loss."

This is not a rare edge case. It is a routine, high-frequency leak in operations that handle grocery, retail and food-and-beverage freight, where receivers commonly require third-party unloading. Each individual fee is small enough that nobody escalates it. Together they add up.

How does the lumper process break down?

The typical flow looks simple:

1. The driver arrives at the receiver and is told unloading requires a lumper.
2. The driver calls or messages the broker for payment.
3. The broker issues a payment code, usually a fuel-card express code, for the quoted amount.
4. The lumper service unloads and issues a receipt.
5. The driver sends the receipt to the broker.
6. The broker bills the shipper per the contract's accessorial terms.

Steps 5 and 6 are where the money goes missing. The receipt:

• Arrives late. Days after delivery, often after the shipper has already been invoiced.
• Arrives unreadable. A blurry photo taken in a dark cab, or a crumpled paper receipt tucked into the BOL packet.
• Never arrives. The driver has moved on to the next load, and nobody followed up.
• Does not match. The code was issued for $250; the receipt says $310. Or the receipt is for $180, and nobody notices the $70 difference was never recovered from the code.

Every one of these ends the same way: the broker cannot support the charge, so the broker absorbs it.

What does it actually cost?

Take an illustrative example. A brokerage handles 400 loads a month that require lumpers, at an average fee of $200. If 10% of those end with no usable receipt, that is 40 fees, or $8,000 a month, roughly $96,000 a year, paid out and never billed. Those figures are illustrative; your own numbers will depend on lane mix and customer base, but the math is easy to run on last quarter's data.

And the direct loss is only part of it. Each receipt chase takes a person several emails or calls, often spread over days. That is the same hidden paperwork cost that shows up across back-office work, and the reason reclaiming freight paperwork spend is often a faster margin win than finding new freight.

Why are lumper receipts so hard to collect?

Lumper receipts are hard to collect because the request usually happens at the wrong time and through the wrong channel. The driver is most able to send a clear photo at the moment of delivery, on their phone; the broker typically asks days later, by email, after the driver has moved on. Close that gap and most of the problem goes away.

Drivers are not ignoring the request out of carelessness. They are managing hours of service, their next appointment, and an inbox full of broker messages. And carriers are already fielding more payment and settlement questions than ever, as diesel above $6 drives a surge in carrier payment inquiries. A receipt request that arrives days later competes with all of that.

How should brokers automate lumper receipt collection?

The fix is to treat the lumper fee as a tracked transaction from the moment it is approved until it is billed, with the receipt collected at delivery and validated automatically.

1. Log the approval. When the driver requests payment, record the load, amount approved, code issued, time and receiver. This is the reference every later step checks against.

2. Request the receipt at delivery, by text. Send an SMS or WhatsApp message to the driver as the delivery completes: "Please send a photo of the lumper receipt for load 48213." One tap to reply with a photo. No email, no portal login.

3. Validate the receipt immediately. Read the photo, extract the amount, date and receiver, and compare them against the approval. If the photo is unreadable, ask for another while the driver is still on site.

4. Flag mismatches. Receipt higher than the approved amount? Escalate before paying the difference. Receipt lower? Record the difference so it can be reconciled against the payment code.

5. Attach and bill. Attach the validated receipt to the load and the shipper invoice, and bill the lumper charge according to that customer's accessorial terms, including any handling fee the contract allows.

6. Reconcile against settlement. When the carrier invoices, confirm the lumper was not billed twice, once as a code and again as a reimbursement request. The same matching logic that automates carrier invoices from email to QuickBooks AP catches these duplicates.

Where AI agents fit

Every step above is a message, a document or a comparison. That is exactly the work AI agents handle well.

An agent working your driver and carrier channels logs the approval when the code is issued, sends the receipt request as the load is marked delivered, and follows up automatically if nothing comes back within an hour. It reads the receipt photo, checks it against the approved amount, and asks for a clearer image on the spot if needed. Validated receipts get attached to the invoice; mismatches get routed to a person with both amounts shown.

This is one piece of a broader discipline. Lumpers sit alongside detention, layover and TONU as accessorials that leak when documentation lags, which is why accessorial capture for detention billing and lumper recovery tend to be fixed together.

Frequently asked questions

Who pays lumper fees? It depends on the contract. Often the driver or broker pays at the receiver, and the cost is billed back to the shipper as an accessorial. Without a receipt, that bill-back usually fails.

What should a valid lumper receipt include? At minimum: the amount, date, receiver or facility, and a reference tying it to the load, such as a PO or load number. Check your customers' accessorial terms for additional requirements.

What if the receipt amount differs from the approved code? Flag it immediately. A higher receipt needs approval before reimbursement; a lower one means part of the payment code should be reconciled.

Can drivers submit receipts without a special app? Yes. A text or WhatsApp message with a photo is the lowest-friction option, and it is the channel most drivers already use.

The bottom line

Lumper fees are paid up front and recovered only with a receipt. Late, unreadable and missing receipts turn a billable accessorial into margin you already spent.

Log every approval, ask for the receipt by text at the moment of delivery, validate it against the approved amount while the driver is still on site, and attach it to the invoice automatically. Stop chasing fees you already paid.
