Every leak below is a gap between what happened in the yard and what reached the invoice. The crew did the work. The business didn’t get paid for it, or didn’t notice it cost more than it earned. Closing these is cheap profit, because the work’s already being done.
1. Units washed and never logged
A crew washes eleven units and writes down nine. Or the sheet says “6 trailers” with no unit numbers, the customer disputes it, and you credit the difference. On a few hundred units a week, missing two percent means several free washes every week.
Log at the stop, by unit number, while the crew’s standing next to the truck. Tapping units off the yard’s list is faster than writing numbers from memory at the end of the night. It also gives the customer an invoice with unit numbers they can check.
2. Add-ons done and never billed, or due and never done
Undercarriage every fourth wash through salt season. Aluminum brightening twice a year. A degrease on the refuse trucks every month. The margin’s good because the truck and crew are already there. But each one depends on somebody remembering it’s due, and somebody else remembering to bill it.
Make the add-on a question the crew has to answer before they close the stop. Either it’s done, with the units ticked, or it’s not done, with a reason. Then the invoice goes off the answer and nobody’s relying on a note.
3. Rates that never went up
Wages, chemicals, fuel and insurance go up every year. The price increase reaches the customers you signed last spring. The yard you’ve washed for six years is still on the rate card it started with. Nobody decided to give that customer a discount. It just grew a little each year.
Review every yard’s rates once a year, in the same month, and send a short written notice with the new rates and the date they start. See how to price fleet washing per unit.
4. The slow yard nobody repriced
Every route has one. The gate’s locked, the trucks are parked nose to tail, there are no lights, and the customer lets them go six weeks between washes. It bills the same per unit as the easy yard and takes half again as long. Without minutes per unit by yard you won’t see it, and you’ll keep winning more work like it.
Take time on site for each stop, from a vehicle tracker if you can so nobody has to write it down, and divide by the units logged. Sort your yards by minutes per unit and look at the slowest five. Reprice them, change how you run them, or let them go.
5. Late invoices and unbilled weeks
An invoice sent three weeks after the work gets paid three weeks later. It’s also more likely to be questioned, because the fleet manager doesn’t remember that night anymore. An invoice that never goes out because the week got busy is revenue you just don’t get.
Send one invoice per yard per week, built from the log, on the same day every week. Keep a running total of work you haven’t billed yet so you see the gap on Monday. Before they go out, look twice at any invoice that’s double or half what that yard usually bills.
6. Rework and the customer who leaves quietly
A trip back to rewash a trailer costs you the drive, the setup and the crew’s time, and earns nothing. The customer who doesn’t call about it is worse. They stop answering and sign with someone else at renewal.
Inspect a few units every week and score them, so you find the misses before the customer does. Keep each yard’s complaints where the crew will read them at the gate. The next crew should know the trailer doors are what this customer looks at.
7. Hourly work counted as units
A dock washout, a tank rinse, a hopper cleanout, a shop floor. That’s hourly work, and it gets logged as “1 unit” and billed at the trailer price. Three people for two hours at a one-unit rate is a bad night.
Log hourly work on its own, as people times hours, at the yard’s hourly rate.
Find the leaks in your own business
Pick one recent month and line up three lists. What the schedule said would be washed, what the crew logged, and what you invoiced. Every difference is one of the leaks above. If those three lists live in three different places, that’s the biggest leak of the lot. See when the spreadsheet stops working.
Common questions
Where does a fleet washing business lose money?
Usually between the yard and the invoice. Units that weren’t logged, add-ons that weren’t billed, rates that haven’t gone up in years, slow yards priced like easy ones, late invoices, rework, and hourly work billed as units.
How do I find unbilled fleet wash work?
Take one month and compare what the schedule said would be washed, what the crew logged and what was invoiced. Every difference is work you did and didn’t bill, or billed and didn’t do.
How The Wash Book helps
In The Wash Book the crew tap units off the yard’s list on their phones, and the invoices are built from that log. Unit tracking is free. Book a demo to see how it handles the other six.
