The General Contractor Business
General contracting is the most complex trade business to start — and potentially the most lucrative. You're not swinging a hammer (most of the time). You're managing projects, coordinating subcontractors, navigating permits, and keeping timelines and budgets on track.
A GC is essentially a project manager with a contractor license. Your value is orchestration, not labor. That distinction shapes everything in your business plan.
Section 1: Licensing & Bonding
General contractor licensing requirements are strict and vary by state:
Licensing costs:- State contractor exam + application: $300–$1,500
- Local business license: $50–$500
- Trade-specific endorsements (if required): $100–$500 each
- Continuing education (annual): $200–$500
- Surety bond: $5,000–$25,000 (you pay 1–3% of the bond amount as premium, so a $10,000 bond costs you $100–$300/year)
- Bond amount varies by state and project type
- Bonding capacity determines the size of projects you can take on
- General liability: $3,000–$10,000/year
- Workers' compensation: $2,000–$8,000/year (even with subs, some states require it)
- Builder's risk insurance: $1,000–$5,000/year
- Commercial auto: $1,200–$3,000/year
- Umbrella policy: $1,000–$3,000/year
Total licensing, bonding, and insurance in year one: $8,000–$25,000. This is the price of admission.
Section 2: Startup Costs
| Item | Low Estimate | High Estimate |
|---|---|---|
| Licensing, bonding, insurance | $8,000 | $25,000 |
| Vehicle | $5,000 | $25,000 |
| Basic tools & equipment | $2,000 | $8,000 |
| Office setup (even home office) | $500 | $3,000 |
| Estimating software | $500 | $2,000 |
| Website & marketing | $2,000 | $5,000 |
| Working capital (6 months) | $20,000 | $60,000 |
| Total | $38,000 | $128,000 |
Working capital is the biggest line item because GCs typically fund materials and sub payments before collecting final payment from the customer. Undercapitalization is the leading cause of GC business failure — you need enough runway to carry 2–3 projects simultaneously.
Section 3: Subcontractor Management
Your subs are your business. A GC with reliable subs delivers quality work on time. A GC with unreliable subs loses clients, eats penalties, and burns out.
Building your sub network:- Vet every sub: license verification, insurance certificates, references from other GCs
- Start with 2–3 reliable subs per trade: plumbing, electrical, HVAC, framing, drywall, painting, flooring
- Always have a backup sub for critical trades
- Pay subs on time, every time — this is how you earn loyalty and priority scheduling
- Scope of work (detailed, not vague)
- Price (fixed, with change order process)
- Timeline with milestones
- Insurance requirements (you should be named as additional insured)
- Payment terms (net 7–15 after milestone completion)
Section 4: Project Pipeline Strategy
GCs need a constant pipeline of 3–6 month forward-looking projects. Here's how to build it:
Residential remodeling (kitchens, bathrooms, additions) is the best starting point. Average project: $20,000–$80,000. Homeowners pay faster than commercial clients and projects are more predictable. New construction is higher revenue but requires more capital, longer timelines, and draw schedules with banks. Save this for year 2–3. Commercial tenant buildouts offer consistent work if you can build relationships with commercial property managers and real estate agents. Lead sources:- Houzz and Angi profiles (high-intent remodeling leads)
- Architect and designer referrals (build relationships with 5–10 local designers)
- Real estate agent partnerships (flippers and investors need reliable GCs)
- Google Business Profile + website with project portfolio
- TradeKit's SEO and booking tools capture organic search traffic and convert it to consultations
Section 5: First-Year Revenue Projections
Months 1–3 (pipeline building): 1 small project + estimates = $15,000–$30,000 total Months 4–6 (gaining traction): 1–2 active projects/month, avg $30,000 = $30,000–$60,000/month Months 7–12 (established): 2–3 active projects/month, avg $35,000 = $70,000–$105,000/month First-year gross revenue: $250,000–$500,000 Gross profit (after subs and materials): $75,000–$150,000 (30% margin target) Net take-home: $50,000–$100,000 after overhead.GC revenue is high, but so are costs. The 30% gross margin target means that on a $50,000 kitchen remodel, you're netting $15,000 before overhead. Maintain tight project accounting — a 5% cost overrun on a $50K project wipes out $2,500 in profit.
Section 6: Project Management Systems
As a GC, your systems are your competitive advantage:
Estimating: Use dedicated estimating software. Spreadsheets break down at 3+ active projects. Your estimates should be detailed enough that change orders are the exception, not the norm. Scheduling: Gantt-style project timelines with sub coordination. When the plumber finishes Tuesday, the drywall crew starts Wednesday. Gaps in your schedule cost money every day. Communication: Daily or weekly project updates to clients. The number one complaint about contractors is poor communication. TradeKit's CRM automates project update messages so clients always know what's happening. Invoicing: Progress billing with clear milestone triggers. Never let your accounts receivable exceed 60 days — chase payments aggressively.The Bottom Line
General contracting is a business of coordination, relationships, and financial management. The GCs who succeed aren't necessarily the best builders — they're the best project managers. Build a reliable sub network, maintain a 6-month project pipeline, and never let your cash reserves drop below 3 months of operating expenses. The rest is execution.
