Florida General Contractor Financial Resources
Build the financial systems that keep projects profitable, protect cash flow, control overhead, and help your contracting business grow without losing visibility into the numbers.
Build a Financial Foundation Before You Grow
Contractors often fail because cash, pricing, job costs, and payment timing are not controlled. A strong financial foundation makes it easier to estimate accurately, collect on time, protect working capital, and understand whether each project is actually profitable.
Separate Every Dollar
Use dedicated business checking, tax savings, payroll, and reserve accounts. Never mix personal and business funds.
Use Job-Costing Software
Your accounting system should track income, labor, materials, equipment, subcontractors, overhead, and project profitability.
Review the Numbers Monthly
At minimum, review profit and loss, balance sheet, cash flow, receivables, payables, payroll liabilities, and job-cost reports.
Job Costing: Know What Every Project Really Costs
Job costing compares the original estimate with actual costs. It reveals where profit was earned, where it was lost, and how future estimates should change.
| Cost Category | What to Track | Common Mistake |
|---|---|---|
| Labor | Wages, payroll taxes, workers’ compensation, benefits, overtime, and supervision. | Using hourly wage only instead of fully burdened labor cost. |
| Materials | Purchase price, delivery, waste, damage, returns, storage, and price changes. | Ignoring waste, freight, and small consumables. |
| Subcontractors | Contract amount, mobilization, change orders, rework, insurance, and retainage. | Failing to capture extras or missing signed scope documents. |
| Equipment | Rental, delivery, fuel, repairs, maintenance, depreciation, and operator time. | Treating owned equipment as free. |
| Permits & Fees | Permit fees, plan review, inspections, engineering, bonds, and utility charges. | Leaving allowances too low or not updating them. |
| Overhead | Office, software, vehicles, insurance, management, accounting, marketing, and administration. | Pricing only direct costs without recovering overhead. |
| Warranty Reserve | Callbacks, punch-list work, service visits, replacement materials, and labor. | Assuming every project will close without additional cost. |
Cash Flow Management
Cash flow planning protects the company between customer payments. The goal is to match incoming cash with payroll, materials, subcontractors, taxes, debt, and overhead.
Use Deposits and Draw Schedules
- Collect deposits when legally and contractually appropriate
- Use milestone-based progress billing
- Invoice immediately when a milestone is reached
- Do not wait until project completion to collect most of the contract
Control Receivables
- State payment terms clearly
- Send invoices promptly
- Review aging every week
- Follow up before balances become severely overdue
Protect Reserves
- Maintain one to three months of fixed overhead
- Keep payroll and tax funds separate
- Reserve cash for warranty and emergencies
- Use credit only as backup, not as permanent operating cash
Markup, Margin, and Profit
Markup and gross margin are related but not interchangeable. Using the wrong percentage can leave a project underpriced even when the estimate appears profitable.
Markup
A 25% markup on $100,000 of cost produces a $125,000 selling price.
Gross Margin
A $25,000 gross profit on a $125,000 selling price equals a 20% gross margin.
Direct Costs
Labor, materials, subcontractors, rental equipment, permits, and project-specific costs.
Overhead Recovery
Office, software, insurance, vehicles, administration, marketing, management, and nonbillable time.
Net Profit
What remains after direct costs, overhead, financing costs, taxes, and other business expenses.
Insurance and Financial Risk Management
General Liability
Protects against covered claims involving property damage, bodily injury, and completed operations.
Workers’ Compensation
Covers qualifying employee injuries and should be included in labor burden and project pricing.
Commercial Auto
Covers business vehicles and should match actual use, drivers, trailers, and equipment exposure.
Inland Marine
May cover tools, equipment, and certain movable property away from the primary location.
Umbrella Coverage
Provides additional liability limits above underlying qualifying policies.
Builder’s Risk and Bonds
May be required depending on project type, owner, lender, municipality, contract, and scope.
Taxes, Payroll, and Recordkeeping
A contractor should have systems for federal taxes, payroll taxes, estimated payments, Florida obligations, record retention, and year-end reporting.
Tax Accounts
- Federal income tax reserve
- Payroll tax withholding
- Estimated tax payments
- Applicable Florida tax accounts
- 1099 and W-2 reporting
Recordkeeping
- Receipts and vendor invoices
- Contracts and change orders
- Payroll records and timecards
- Mileage and vehicle expenses
- Asset purchases and depreciation records
Professional Support
- Construction-experienced bookkeeper
- CPA or tax professional
- Payroll provider
- Insurance agent
- Attorney for contracts and collections
Banking, Credit, and Financing
| Financial Tool | Best Use | Risk to Control |
|---|---|---|
| Business Checking | Customer deposits, vendor payments, payroll, and operating expenses. | Mixing project, tax, and personal funds. |
| Business Savings | Taxes, reserves, warranties, insurance renewals, and planned purchases. | Using reserves for routine overspending. |
| Line of Credit | Short-term timing gaps and approved project cash cycles. | Using revolving debt to cover chronic losses. |
| Equipment Financing | Vehicles or equipment with predictable utilization and useful life. | Payments exceeding the equipment’s contribution to profit. |
| SBA or Term Loan | Expansion, acquisition, working capital, property, or major systems. | Borrowing before the business model and cash flow are proven. |
| Business Credit Card | Controlled purchases, travel, subscriptions, and short-cycle expenses. | Carrying high-interest balances or losing receipt control. |
