Stop Guessing Which Job Actually Made You Money

Ask a solo contractor which job last month was their best one, and most will name the biggest invoice. That's usually the wrong answer — revenue and margin aren't the same thing, and the job with the biggest number on the invoice is frequently the one with the thinnest margin once you actually account for materials, callback time, and how long it really took versus how it was quoted.

This isn't a knock on anyone's math skills. It's that margin-per-job is genuinely tedious to calculate by hand across a month of jobs, so it just doesn't get done — decisions about what kind of work to take on next get made on gut feel about which jobs "felt" profitable, which is a noisy signal at best.

What a real margin check looks like

Feed a job-cost CSV in — job name, revenue, materials cost, labor hours — and get two things out: a margin chart that makes the actual pattern visible at a glance, and a plain-English write-up that says which job types are quietly subsidizing which other ones.

The value isn't the chart itself. It's the decision the chart makes obvious: maybe the small quick jobs you've been treating as filler between "real" jobs are actually your best margin, and the big jobs you've been chasing are the ones eating your weekends for a worse return. You can't act on that if it's never been laid out plainly.

Job Cost Insights turns a CSV you already have into a chart and a write-up you can actually use to decide what to bid on next.
