Case Study: Improving Margin Control for a General Contractor

The Issue

A general contractor approached us after experiencing ongoing margin erosion across multi-phase projects. While individual jobs appeared profitable at the outset, financial performance became increasingly inconsistent as projects progressed.

In addition, WIP (Work-in-Progress) reporting lacked structure, making it difficult to accurately assess job health in real time. This resulted in uncertainty around true project profitability and irregular billing positions.

Our Approach

We focused on strengthening the contractor’s internal costing and reporting discipline to improve visibility and control across active projects.

Key improvements included:

  • Implementation of structured cost codes across all projects
  • Introduction of monthly job costing reviews to track performance trends
  • Formalized WIP tracking process aligned with project milestones
  • Improved consistency between field progress, cost capture, and billing activity

This created a more reliable feedback loop between project execution and financial reporting.

The Outcome

The review uncovered approximately 5% in additional recoverable revenue that had not been billed despite being contractually supported and substantially completed.

Results Achieved

Gross margin improved from 18% to 24%

Reduced overbilling and underbilling volatility across projects

Strengthened lender-ready reporting with clearer, more reliable job performance data

Key Takeaway

Margin erosion in construction is rarely caused by a single issue—it typically stems from gaps in cost tracking, reporting discipline, and billing alignment. Establishing structured job costing and consistent WIP practices creates the visibility needed to protect margins and support stronger financial decisions.
