Why Job Costing Can Make or Break Your Business
When you’re juggling materials, labor, equipment and tight deadlines, it’s easy to focus on getting the job done and forget to look at how much each job is actually costing you.
But here’s the truth: if you’re not tracking the cost of each project, you could be losing money without even realizing it.
That’s where job costing comes in.
What is Job Costing?
Job costing is the process of tracking all the costs associated with a specific project - including labor, material, subcontractors, equipment, and other expenses.
When done right, it tells you:
How profitable a job really was
Where your money is going
Which types of projects bring the best return
And where you can tighten up spending next time
Why It Matters (Especially for Contractors & Services Businesses)
In the construction and service world, no two jobs are exactly the same. Flat-rate pricing and gut estimates might work in the beginning - but as your business grows, not knowing your true costs can lead to underbidding, cash flow issues, and shrinking profit margins.
Without job costing, you’re guessing. With job costing, you’re in control
Real Examples: Two Jobs, Two Very Different Outcomes
Let’s day you take on two HVAC installs:
Job A: Looks small, simple, and fast. You quote it low
Job B: Bigger scope, but you price it right.
Without job costing, you might assume Job A was more profitable - because it wrapped up quickly.
But after tracking labor overruns, material delays, and a call-back, Job A ends up making you less per hour than Job B.
Now imagine that happening on 5-10 projects a month. That’s real money left on the table.
What Should Be Included in Job Costing?
A good job costing system tracks:
Direct Labor - Time spend on the job, including wages and payroll taxes
Materials - Supplies used for the project, including delivery cost
Subcontractors - External trades or crews brought in
Equipment Rentals or Usage - Cost of tolls or machinery
Permits, Fees, & Overhead - Anything project - specific
