Contractor: Finding 14 Points of Margin Hidden in Job Mix

Outlined below is an example of patterns we see constantly in contracting businesses. It is worth walking through, because the problem hides in plain sight and the fix is available to almost any contractor willing to look.

The Challenge: Busy, Growing, and Barely Profitable

A specialty contractor comes to us doing about $4 million a year in revenue. By every visible sign the business is thriving. The crews are booked out for months, revenue has grown 3 years running, and the owner is working harder than ever. Yet the bank account never reflects it. After a strong year the net margin sits at around 4%, and the owner cannot say why. The books are accurate. The profit just is not there.

The owner's instinct are that overhead has crept up, so the plan is to cut costs across the board. That instinct is wrong, and acting on it would hurt the parts of the business that are actually working.

What We Find: The Average Is a Lie

The business tracks profit at the company level only. Every job flows into one big bucket, and the bucket shows a thin overall margin. What it hides is that the jobs are not similar to each other at all.

We set up job-level costing, assigning each job its true direct costs including labor with full burden, materials, and equipment time, plus a fair share of overhead. Then we rank the jobs by actual margin. The spread is dramatic. One category of work, a type of job the owner took on readily because it kept crews busy and the phone ringing, is running at a deeply negative margin once real labor burden and rework are counted. It is losing money on every project. Another category, less glamorous and rarely marketed, earns strong double-digit margins.

The profitable work has been quietly subsidizing the unprofitable work for years. The company-level average, that thin 4%, is simply the two blending together. The owner had been selling more of the losing work because it was easy to win, which grew revenue and shrank profit at the same time.

What We Do

The fix follows directly from the data. We do not cut across the board, which would starve the healthy jobs. Instead we reprice the unprofitable category to reflect its true cost, which means meaningful price increases on that specific type of work. Some of those jobs go away, and that is fine, because they have been losing money. We shift marketing and crew capacity toward the high-margin work the business has been underselling. And we give the owner a simple job-level report so this could never hide again, with target margins set before any bid goes out.

The Results

Within two quarters the picture changes. Blended net margin moves from roughly 4% toward 18%, a swing of about 14 points, on slightly lower revenue. Read that again: less revenue, far more profit. The business stopped chasing work that cost it money and doubled down on work that paid. The owner, for the first time, could look at a bid and know before signing whether it would make money.

The Takeaway for Your Business

Busy is not the same as profitable, and a healthy-looking total can conceal jobs that lose money on every invoice. If you run any kind of project or job-based business and you only measure profit at the company level, you almost certainly have some version of this hidden inside your mix. The tool that reveals it is job-level costing, and the payoff is often exactly this large, because you are not creating new profit so much as stopping an existing leak. Uncovering this kind of hidden margin is one of the most common early wins of a fractional CFO engagement, and it is frequently what pays for the engagement several times over.
