Starting a field-service business — HVAC, plumbing, electrical, roofing, residential or light commercial — is one of the most resilient career paths in 2026. Recession-proof demand, cash margins higher than software, and a labor pool that’s structurally undersupplied for the next decade. This guide is the honest end-to-end roadmap: from the “should I do this?” gut check, through licensing and first-job logistics, to the operating playbook for year one. It’s the conversation you’d have with a 25-year veteran over coffee, condensed.
Estimated reading time: 18 minutes
Part 1: Should you do this?
The unromantic gut check, before you spend money:
You should do this if:
- You can fix things with your hands (or you’re willing to apprentice 6-12 months to learn)
- You’re comfortable being on call sometimes — emergencies don’t respect dinner plans
- You can hold your own in a homeowner conversation (50% of the job is communication, not wrenching)
- You can run numbers — invoicing, taxes, parts cost vs. sell price isn’t optional knowledge
- You have 3-6 months of personal runway (more on this in Part 3)
You should NOT do this if:
- You hate paperwork (this business has more than you think — invoices, permits, warranties, taxes)
- You can’t say “no” to a customer demanding a discount that destroys your margin
- You think running your own thing means working less than a job — the first 18 months it’s the opposite
If both lists landed mostly in the right column, you’re in. Keep reading.
Part 2: Pick the trade
The big three for a solo or small operation:
- HVAC — highest ticket size, highest skill barrier, biggest reward; ~$200-450/hr loaded billable in major metros
- Plumbing — middle ticket size, good emergency premium, reliable demand; ~$150-300/hr
- Electrical — slightly higher tickets than plumbing, license-heavy, growing share due to EV/solar; ~$180-350/hr
Adjacent options worth considering: appliance repair, garage door installation, drain cleaning specialty, irrigation, low-voltage (security/networking).
Don’t pick by what pays most. Pick by what your local market is undersupplied in (Google Maps + a 30-mile radius search will tell you in an afternoon) and what you’re either trained in or can apprentice into within 6 months.
Part 3: The first 6 months — finance and licensing
Three buckets of money you’ll spend before you make any:
Licensing and bonding ($800-3,500)
Varies by state and trade. Most jurisdictions require:
- Trade license (test + experience requirement, sometimes journeyman vs. master tiered)
- General contractor license if you’re doing installations
- Surety bond ($5,000-25,000 face, ~1-3% premium per year)
- Workers comp + general liability insurance ($100-300/month minimum)
Don’t try to skip these. Working uninsured is the fastest way to lose your house.
Tools and truck ($8,000-25,000)
- Used cargo van or truck: $5,000-15,000 (don’t buy new in year one)
- Initial tool kit: $2,000-5,000 for plumbing/electrical, $3,000-8,000 for HVAC
- Initial parts inventory: $1,000-2,000 (you’ll grow this from job revenue)
- Tablet + phone (for software): $500-1,000
- Branded uniform / shirts: $200-500
Software and operations ($100-1,500/month)
- Field service management platform (Exoserva or competitor): tier-dependent
- Accounting (QuickBooks Online): $30-90/month
- Phone/SMS service: $30-100/month
- Marketing (Google Ads, website): $300-1,000/month for first 6 months
The third bucket is where contractors who fail and contractors who succeed diverge. The right tools and the discipline to use them is the lever between “three jobs a week” and “three jobs a day”.
Part 4: First customer in 30 days — the bootstrap playbook
Here’s how to land paying jobs without an existing book:
Week 1-2: Set up the surface
- Register the LLC or sole proprietorship
- Get the licenses and insurance certificates
- Build a simple Google Business Profile with photos and your service area
- Write a one-page website (or use the free Exoserva-hosted booking page)
- Set up the phone number and the AI receptionist (Setting Up Voice AI)
Week 3: Talk to your network
The first 5-10 jobs almost always come from someone who already knows you. Tell every:
- Family member
- Past coworker
- Person at your gym, church, kid’s school, or hobby club
- Real estate agent in your zip code (they refer constantly)
A simple “I just started doing X — if you ever need someone, here’s my number” converts at 10-20% over 60 days.
Week 4: Buy your first 50 leads
Go where homeowners actively search:
- Google Local Services Ads — pay-per-lead, your business shows in the top 3 of relevant searches
- Thumbtack / Angi — pay per booked lead; lower quality but higher volume
- Nextdoor for Business — surprisingly effective in suburbs
Budget: $500-1,500 in the first month. Track every lead source in your software so you know which channels deserve the next dollar.
Part 5: The operating cadence — week 1 onward
Three rituals separate the contractors who scale from the ones who burn out:
Daily (15 minutes, end of day)
- Mark every completed job as complete in your software
- Send invoices for every completed job (Exoserva: Ready-to-Invoice banner)
- Reply to every customer message in your inbox
- Schedule tomorrow’s jobs in the morning’s first hour
Weekly (60 minutes, Friday afternoon)
- Review the Owner Dashboard (guide)
- Check overdue invoices and send reminders
- Restock the truck for next week
- Pay yourself if you can (most owners pay themselves last and regret it)
Monthly (2 hours, last Friday)
- Reconcile QuickBooks vs. your software
- File quarterly tax estimates if you owe them
- Review pricing — anything you’re losing money on?
- Review reviews — respond to every Google review, good or bad (guide)
This is small. It’s also the difference between a $80k-net solo operation and a $250k-net 3-tech shop in 36 months.
Part 6: When to hire your first employee
You’re ready to hire when:
- You’re consistently turning down 5+ jobs per week for capacity reasons
- Your net profit (after all costs including paying yourself a salary) is at least $80k/year
- You have 8-12 weeks of cash reserve
- You’ve documented the work — onboarding a tech with no SOPs takes 6 months instead of 6 weeks
The first hire is the most leveraged decision you’ll make. Get it right and the business becomes a second income stream; get it wrong and you’ll work harder than before for less money.
Part 7: The five mistakes that kill year-one contractors
Patterns from contractors who didn’t make it past 18 months:
- Underpricing to win jobs, then realizing the margin doesn’t cover their costs (especially insurance and tools)
- Skipping invoices for “small” jobs — by year-end they’ve miscounted $20-30k of revenue and can’t reconcile
- No emergency premium — emergencies cost the customer 2-3x because they cost the contractor 2-3x; charging the same as a scheduled call is a slow-motion bankruptcy
- Spending lead-generation budget without tracking source — every dollar of marketing should map to a booked job
- Hiring too early or too late — see Part 6
Most of these are software-preventable. Software won’t save a contractor who refuses to look at numbers, but it makes the right behavior easy and the wrong behavior visible.
Part 8: Where Exoserva fits
A field-service platform should compress the time from call comes in to cash in account without you having to think about it. The features that earn their keep on day one:
- AI Voice receptionist (guide) — answer 24/7 even when you’re under a sink
- Schedule board + Auto-Assign (guide) — match the right tech to the right job without a spreadsheet
- Price Book + Good-Better-Best estimates (guide) — quote without undercharging
- Invoicing with one-click reminders (guide) — DSO drops 15-25 days
- Reviews-and-follow-ups automation (guide) — every job becomes a review request and a future-job lead
In year one, a contractor who uses all five buys back ~10 hours a week. Year two, that’s the difference between burning out solo and being ready to hire.
