🏗️Construction Business Plan
Construction businesses operate on project-based revenue with highly variable margins. The biggest financial challenges are cash flow timing (paying crews and materials before getting paid by clients), accurate job costing, and managing change orders. Successful contractors track cost-per-job religiously and maintain a strong pipeline. Bonding capacity limits growth for many contractors.

Construction Business FAQs
What profit margin should a construction company target?
Residential contractors typically target 20-35% gross margin and 5-10% net margin. Commercial contractors work on tighter margins (15-25% gross) but larger project volumes. The most common mistake is underbidding. If your net margin drops below 5%, you are likely not accounting for all overhead.
How do construction businesses manage cash flow?
Cash flow is the number one reason construction businesses fail. Use progress billing (billing at milestones rather than completion), require deposits (25-50% upfront for residential), and negotiate 30-day terms with suppliers. The Cash Flow Forecast calculator helps you model payment timing gaps.
How much does contractor insurance cost?
General liability insurance runs $1,500 to $5,000 per year for small contractors. Workers compensation varies by state and trade but averages 5-15% of payroll. Commercial vehicle insurance adds $2,000 to $5,000 per truck. Bonding costs 1-3% of the bond amount annually.
