Most quotes that lose money are not priced carelessly. They are priced confidently — with one or two real costs simply left off the sheet. Here are the five that go missing most often.
1. Labor burden
Estimating labor at the wage on the paycheck ignores payroll taxes, workers’ compensation, benefits, and paid nonproductive time. On a labor-heavy job the burden that gets skipped is often bigger than the profit the job was supposed to make.
2. Overhead
Rent, insurance, software, the truck, and unbilled office time do not attach to one job, so they are easy to leave out. But they still have to be paid, and if the price does not recover them, they come straight out of profit.
3. Disposal and dump fees
Tear-off, debris, and haul-away have real weight and real tipping fees. On remodels and roofing they can move a quote by hundreds of dollars, yet they rarely appear on a quick estimate.
4. Mobilization and travel
Loading, drive time, staging, and return trips are paid hours that produce no billable work at the site. A job an hour away is not the same cost as one down the street.
5. Small tools, consumables, and callbacks
Blades, fasteners, tape, and the occasional warranty return are small individually and meaningful across a year. A modest consumables and callback allowance keeps them from eroding margin invisibly.
The fix is a checklist, not a bigger number
You do not need to pad the price. You need every real cost on the sheet before you apply markup or margin, so the profit you quote is the profit you keep.
Frequently asked questions
What costs are most often left off a quote?
Labor burden, overhead, disposal and dump fees, mobilization and travel, and small tools, consumables, and callbacks.
Should I just pad the price to be safe?
No. Put every real cost on the sheet first, then apply markup or margin, so the quoted profit is the profit you keep.
Why is labor burden so easy to miss?
Because the wage is visible and the payroll taxes, workers' comp, benefits, and nonproductive time are not.
