It’s hard to run a construction business. As the owner, you could be juggling many hats -
From estimating, hiring, billing, chasing receipts—and at the end of the day, you're still unsure if you made money on that last job.
This is where job costing comes in. Done right, it can completely change how you run your business. Today, we’re sharing three real-life examples of job costing in business that transformed contractor’s operations—and how you can do the same.
Job costing is the process of tracking all costs associated with a specific job or project. This includes:
Direct costs like labor, materials, and equipment
Indirect costs such as admin time, permits, and insurance
Instead of looking at overall business performance, job costing breaks it down per project, so you know exactly what each job costs and how much it’s making you.
This level of clarity helps contractors bid smarter, stop profit leaks, and avoid surprises halfway through the job.
In construction, every project is different—different scopes, timelines, materials, and crews. Without job costing, it’s almost impossible to know which jobs are profitable and which are draining your cash.
Here’s why job costing matters:
In short, it helps you build smarter.
Here’s how genuine contractors changed their businesses with better job costing:
Mike runs a small residential contracting business. He managed everything—bids, crews, invoices, and QuickBooks—on his own.
The Problem:
Mike was constantly busy but never sure which jobs were profitable. He’d lump all his expenses together and hope for the best.
The Fix:
Once Mike started using Ontraq’s job costing system, every receipt, material order, and labor hour was automatically tied to the correct job.
The Result:
He realized one of his biggest jobs was barely breaking even due to underestimated labor. With that insight, he adjusted his estimates going forward—and now tracks profit on every project in real time.
“Before Ontraq, I was spending Sunday nights catching up on paperwork. Now I can see exactly which projects are profitable without the data entry headaches.” — Mike T., Residential Contractor
Sarah owns a fast-growing remodeling company. She was about to hire a junior bookkeeper to keep up with project costs.
The Problem:
Her office manager was drowning in admin, and delays in financial reporting meant she didn’t know where jobs stood until weeks later.
The Fix:
Instead of hiring someone full-time, Sarah switched to Ontraq. With AI handling the receipt tracking and job-cost tagging, she got up-to-date job reports—without hiring another person.
The Result:
She saved over $3,000 a month compared to hiring a bookkeeper and now makes project decisions based on real-time data.
“Now our office manager focuses on customers, not data entry. Our books are always accurate, and we didn’t need to expand our payroll.” — Sarah L., Commercial Remodeler
Carlos is an electrical contractor—great at his trade, not so great with admin.
The Problem:
He struggled to track material and labor costs per job. That meant poor job visibility and a tendency to underbid because he lacked solid historical data.
The Fix:
Carlos started uploading receipts and timesheets into Ontraq. Everything got automatically tagged to the right job, and he finally had accurate records of real costs.
The Result:
He used historical data to create more accurate bids, avoided undercharging, and now wins profitable jobs instead of low-margin headaches.
“Ontraq gives me the financial clarity I need without taking me away from the jobsite. My estimating has improved dramatically.” — Carlos R., Electrical Contractor

Because every job is different. Without job costing, it’s easy to lose money without realizing it. Job costing helps you track every dollar so you can stay profitable.
Job costing is most impactful in any project based industry - for example: construction, custom manufacturing, and creative services—where each job has unique costs and timelines.
Think of a remodeler bidding on a home addition. He would use job costing to track material, labor, and subcontractor costs for that specific job.
From builders, remodelers, to trade contractors (like HVAC, plumbers, electricians) all use job costing. Ontraq helps automate the process for them.
