StashGrade for plumbing
Revenue per service call. Margin by job type. See which work actually pays.
Service calls, new construction, remodels, drain cleaning. The revenue per tech per day looks like one number but four different business models are running inside it. StashGrade reads the split.
Where plumbing companys leak money
Truck stock markup applied inconsistently
On service calls, technicians pull from truck inventory. The markup applied to those materials varies by tech, by job, and sometimes by mood. Some jobs get charged at retail, others at cost. Across 800 service calls a year, the difference between consistent and inconsistent markup can be $40K.
New construction running at 30% while service calls run at 65%
Both land in "plumbing revenue." New construction is competitive, material-heavy, and frequently priced to win the bid rather than to make money. Service work is high-margin and often under-tracked. When the mix shifts toward new construction, blended margin drops but the owner may not see why.
Fixture upgrades agreed to in the field, never invoiced
A tech verbally agrees to a better faucet, a different fixture, a change in the scope. No change order, no updated invoice. The material cost goes on the job; the revenue does not. A $200 fixture upgrade done across 50 remodel jobs is $10K in revenue the books never saw.
After-hours labor at standard rates
Evening and weekend service calls generate real premium customer demand. The labor cost on those calls runs 1.5-2x standard rate. If the invoice rate doesn't match the cost rate, after-hours work quietly runs near break-even. The books show the labor cost; the margin column shows the truth.
