Material, labor, and subcontractor costs keep moving. The key is seeing the financial impact before the job is finished.
Rising costs are only part of the problem
A job can look profitable when the contract is signed and tell a different story a few months later. Material prices move, labor runs long, and change orders can slip through billing.
Construction input prices were 7.4% higher year over year in July 2026, while home builders reported a median 6.7% increase in material costs.
The real issue is not that costs change. It is finding out after most of the job is already complete.
What to Watch
- Estimate vs. actual costs
- Committed costs
- Labor overruns
- Unbilled change orders
- Shrinking gross profit
Use recent job data when pricing new work
Your completed and active jobs should inform the next estimate. Compare actual materials, labor, subcontractor costs, and the scopes that repeatedly run over budget. If estimating and accounting are working from different numbers, margin problems are easy to repeat.
Your financial system was simply late in showing it.”
Track what has been spent — and what is already committed
A job may look healthy simply because some costs have not hit the books yet. Open purchase orders and materials ordered but not billed still matter. Seeing actual and committed costs together gives a more realistic picture of job profitability.
Watch for margin fade
If expected gross profit keeps shrinking, investigate while the job is active. Common causes include labor overruns, higher materials, scope changes, unbilled changes, and miscoded costs.
Make change orders reach accounting
A change can be approved in the field and still hurt margin if accounting never receives it. Every change should be documented, added to contract value, tracked for cost, and billed.
Watch Labor Costs and Protect Cash Flow
Materials get the headlines, but labor overruns can hurt just as quickly. At the same time, a profitable job can still strain cash if receivables are slow while payroll, suppliers, and subcontractors are due. Profitability and cash flow should be reviewed together.
Your financials should help you make decisions before the job is finished
You should be able to answer:
- Which jobs are losing margin?
- Where are actual costs above estimate?
- Are approved change orders being billed?
- What committed costs have not hit the books yet?
- Is recent job performance telling you to change pricing?
The goal is better visibility
No contractor can predict every material, labor, or subcontractor cost. What you can control is how quickly you see the impact. Accurate job costing, current books, clear cost codes, and regular estimate-versus-actual reviews make problems easier to catch while there is still time to act.
