If you've worked in construction long enough, you've probably wondered about the difference between being a subcontractor and becoming a general contractor. They sound similar, but the roles are fundamentally different. Your choice between them affects your income, your responsibilities, your risk, and your workload.
This guide breaks down what each role actually entails, the financial realities of each path, and how to know which is right for you.
What's the Difference? Roles and Responsibilities
Subcontractors: Trade Specialists
A subcontractor performs a specific trade on a project and reports to the general contractor. You're a specialist—electrician, plumber, roofer, concrete finisher, etc. Your responsibilities are focused:
- Perform your specific trade according to plans and specs
- Manage your own crew and schedule
- Coordinate with the GC regarding timing and site logistics
- Complete your work and pass inspections
- Submit invoices and manage your payment timeline
You execute the work the GC contracts you to do. Your liability is limited to your scope of work.
General Contractors: Project Managers
A general contractor manages the entire project on behalf of the property owner. The GC is responsible for everything:
- Winning the initial contract (client relationship and bidding)
- Creating project schedule and coordinating all trades
- Hiring and managing all subcontractors
- Managing the overall project budget and profitability
- Obtaining permits and managing inspections
- Managing site safety and compliance
- Communicating with the owner throughout the project
- Handling change orders and project modifications
- Collecting payment from the client and paying subs
A GC is liable for the entire project—if something goes wrong, the owner comes to the GC first. The GC then pursues subs responsible for specific failures. This creates significantly more legal and financial exposure.
Head-to-Head Comparison
| Aspect | Subcontractor | General Contractor |
|---|---|---|
| Scope of Work | One trade or specialty (electrical, plumbing, etc.) | Entire project coordination |
| Client Relationship | Works through GC (indirect relationship with owner) | Direct relationship with owner |
| Revenue Source | Bid for contract work from GCs | Win contracts directly from owners, markup subs' work |
| Typical Margin | 10-20% depending on specialty | 5-10% on total project (but covers all trades) |
| Risk/Liability | Limited to your scope and bonding requirements | Project-wide liability (including subs' work) |
| Payment Terms | Net 30-60 (sometimes longer) | Depends on owner contract, usually Net 30-45 |
| Hours/Schedule | Work your trade, often predictable hours | Full-time project management, often long hours |
| Bonding Requirements | Bid bond + Performance bond (varies) | Bid bond + Performance bond + Payment bond (required on most projects) |
The Money: What Do They Actually Earn?
Subcontractor Economics
Let's say you're an electrical contractor with annual revenue of $800,000:
- Revenue: $800,000
- Typical margin: 12% (reasonable for mid-market electrical work)
- Gross profit: $96,000
- Overhead (insurance, vehicles, admin): ~$30,000
- Net profit before taxes: ~$66,000
A well-run sub business at $800K revenue generates roughly $60-80K net profit per year. The advantage is predictability—you know your costs, you control your work quality, and your liability is contained.
General Contractor Economics
The same GC wins a $4M project and hires subs (including that electrician) to do the work:
- Project revenue: $4,000,000
- Typical GC margin: 7% (lower margins on bigger projects, but covers all trades)
- Gross profit: $280,000
- Project overhead (management, site, etc.): ~$150,000
- Contingency/Risk buffer: Variable (often 2-5% of GC profit gets consumed by subs' issues)
- Net profit on project: ~$80-100K (if no major problems)
But a GC manages 4-5 simultaneous projects of that size, so annual revenue climbs to $15-20M, generating $500K-$1M+ in net profit. The catch: if one project goes bad, it can wipe out profit from others.
Profitability Reality
GCs earn more in absolute dollars on big projects, but per dollar of revenue, sub margins are often higher. And subs have far lower project risk. A job going $50K over budget is catastrophic for a GC; for a sub doing $800K revenue, it's significant but not fatal.
The Real Difference
Subs earn steady, predictable margins on focused work. GCs earn higher total profit, but it's volatile—dependent on winning bids, managing multiple projects, and mitigating sub performance issues. More money, more stress.
Pros and Cons: Which Is Right for You?
Subcontractor Pros
- Focus on your expertise—do the work you're good at
- Limited liability and risk exposure
- Predictable revenue and costs
- Lower bonding requirements and insurance costs
- You're not liable for other trades' failures
- Easier to scale within your specialty
- More predictable work schedule
Subcontractor Cons
- Dependent on GCs for work/relationships
- Payment delays (waiting for GC to get paid)
- GC controls project schedule and terms
- Lower margin potential than GCs
- Limited direct owner relationships
- Vulnerable to GC insolvency (you may not get paid)
- Bound by GC contracts you didn't negotiate
General Contractor Pros
- Direct owner relationships and larger contracts
- Higher absolute profit potential
- Control over project scope and schedule
- Ability to manage and profit from multiple trades
- Less dependent on specific skill set
- Scaling potential (grow to much larger revenue)
- Opportunity to manage project profitability
General Contractor Cons
- You're liable for entire project performance
- Must manage multiple subs and trades
- Requires constant business development (winning contracts)
- Cash flow challenges (you pay subs before you get paid)
- High bonding and insurance costs
- Volatile profitability (one bad job kills a good year)
- Full-time business management required
- Dependent on market conditions and owner quality
When Should You Transition from Sub to GC?
Not every sub should become a GC, and not every GC stays one. Here's when the transition makes sense:
You Should Become a GC If:
- You've maxed out your sub specialization (not growing revenue anymore)
- You have strong owner/developer relationships that could lead to direct contracts
- You understand project management and can manage multiple trades
- You have capital to float cash flow (you pay subs before you collect from owners)
- You can secure bonding (performance and payment bonds are expensive for GCs)
- You're prepared for volatile profitability and significant project risk
- You want to build a larger, multi-trade business
You Should Stay a Sub If:
- You're profitable and growing in your specialty
- You prefer focused work without full-time management
- You value predictability and lower risk
- You lack capital reserves for GC cash flow challenges
- You don't have owner relationships or business development skills
- Your specialty has strong market demand and margins
- You're happy with your current income level
The Hidden Cost of Being a GC
GCs spend 30-50% of their time on business development, management, and problem-solving instead of the actual work. If you love the technical work, GC life will frustrate you. Many successful subs tried to become GCs and regretted it because they missed the actual trade.
The Middle Path: Growing as a Specialty Subcontractor
You don't have to choose. Many successful contractors grow from single-person subs to multi-million-dollar specialty contractors without becoming GCs. Examples:
- Electrical contractor that becomes "the" expert in healthcare facility electrical work
- Concrete company that dominates foundation and structural concrete in a region
- Roofing specialist that focuses solely on commercial roofing
These companies earn high margins (15-25%), attract premium customers, and achieve significant scale—$10-50M+ revenue—by being exceptional at one thing rather than trying to coordinate many trades. Less risk than being a GC, higher margins than average subs, and you stay connected to the actual work.
Bottom Line: Know Your Path
Being a subcontractor is a solid business with good economics, predictable risk, and the satisfaction of excellent execution. Being a general contractor offers higher absolute profit but requires more capital, carries more risk, and involves less actual work and more management.
Choose based on what you're good at and what you want to do with your time. Many of the most successful contractors in your market are specialized, profitable subs—not GCs. Don't feel like you have to become a GC to be successful. Often, you're more successful staying excellent at what you do.
