Job Profitability Analysis: Measuring What Matters After Completion

Contract Revenue: Start with the original contract amount. This is straightforward but remember: original contract is often only a portion of total revenue.

Change Orders: Approved change orders add revenue. But pending change orders represent potential revenue that may or may not materialize. Track both approved and pending separately. A job with $50,000 in pending change orders is different from one with none.

Rework and Warranty Reserves: Every job has some rework and warranty exposure. A reasonable reserve (2-5% depending on job type) should reduce reported profitability. If you don't reserve, you're overstating job profit.

Mobilization and Demobilization: Moving people and equipment to and from the job site has real costs. Make sure these are captured—either as direct job costs or allocated appropriately.

Overhead Allocation: Your overhead (office rent, admin salaries, insurance, etc.) must be recovered through job margins. Allocate overhead to jobs using a reasonable method—typically direct labor dollars, direct labor hours, or revenue.

Cash Flow Impact: A long-duration job that bills slowly may require you to finance the work for months. The time value of money affects real profitability, especially on large projects.

The Bottom Line: A job with $100,000 revenue and $70,000 direct costs might look like 30% gross profit. But add $10,000 overhead allocation, $5,000 in unapproved change orders, and $3,000 in warranty reserve, and true profit is only $12,000—12%.

By Project Type: Which types of projects consistently generate better margins? Commercial TI vs. ground-up? Renovation vs. new construction? Service vs. installation? This analysis should inform which work you pursue.

By Customer: Are certain customers more profitable than others? Some customers may generate good revenue but require excessive hand-holding, scope changes, or prompt payment. Track profitability by customer to identify relationships worth nurturing—and ones to avoid.

By Contract Type: Do you perform better on lump sum or cost-plus work? Each has different risk and reward profiles. Understand your true performance by contract type.

By Division/Department: If you have multiple divisions, compare profitability. One division might contribute revenue while another contributes profit. Understand the true economics of each.

By Estimator/Project Manager: Different people estimate and manage differently. While you shouldn't penalize for learning, tracking profitability by estimator reveals systematic estimating accuracy.

By Geography/Location: Jobs in certain locations may have higher costs due to travel, permits, or labor markets. Understand geographic profitability.

Pricing New Work: Use historical profitability data to inform bids. If similar projects have yielded 15% net margin, bid work to achieve at least that—or understand why you can do better. Never bid blind.

Identifying Underperforming Areas: When profitability drops, investigate. Is it a labor productivity issue? Material waste? Excessive change orders? The answer points to the solution.

Evaluating Service Lines: Use profitability data to decide whether to add or eliminate service lines. A service that generates revenue but not profit may not be worth pursuing.

Customer Prioritization: Not all customers deserve equal treatment. Your most profitable customers deserve the best service. Underperforming customers may need pricing adjustments or relationship changes.

Team Performance: Share profitability data with project managers and estimators. Make it part of performance discussions. Everyone should understand how their decisions impact profitability.

Resource Allocation: Where should you invest? Profitability data guides decisions about equipment purchases, hiring, and expansion.

Month 2: Define Profitability Reports. Create standard reports showing job profitability including all factors.

Month 3: Analyze Completed Jobs. Review profitability of all jobs completed in last 6-12 months. Identify patterns.

Month 4: Establish Trends. Create trend analysis by project type, customer, contract type. Document findings.

Month 5+: Integrate into Decisions. Use profitability data in pricing, resource allocation, and customer decisions.
