Dave's been running his plumbing business out of Van Nuys for three years. His "phone system" is his personal iPhone. Customers call his cell, he answers when he can, and when he can't — which is most of the day — they get his voicemail. He knows he needs something better, but the options are overwhelming: VoIP, virtual numbers, Google Voice, call centers, AI answering... where do you even start?
If you're a small contractor trying to figure out the best phone setup for your business, this guide cuts through the noise.
What Small Contractors Actually Need
Before diving into options, let's define what "best" means for a 1-15 person contracting operation:
- Separate business number — stop giving out your personal cell
- Professional greeting — not "uh, hello?"
- Missed call handling — something better than voicemail
- After-hours coverage — emergencies don't wait until 8 AM
- Simplicity — you're a plumber, not an IT department
- Affordable — you're not a Fortune 500 company
With that in mind, here are your real options.
Option 1: Personal Cell Phone (What You're Probably Doing Now)
Cost: $0 additional Setup: Already done
Pros:
- Free
- Simple — one phone for everything
- You see every call come in
Cons:
- No work/life separation
- Voicemail is your only backup (67% of callers hang up)
- Looks unprofessional on Google Business Profile
- No way to have someone else answer for you
- Can't track business calls separately
Verdict: This works when you're just starting out and getting 2-3 calls a week. Once you're getting consistent calls, you're leaving money on the table.
Option 2: Google Voice
Cost: Free for personal, $10/month per user for business Setup: 15-30 minutes
Pros:
- Separate business number for free (or cheap)
- Basic call forwarding
- Voicemail transcription
- Works on your existing phone
Cons:
- Still relies on voicemail when you can't answer
- Limited call routing options
- No emergency alerting
- Occasional call quality issues
- Can't port all existing numbers
Verdict: A solid step up from your personal cell. Gets you a business number and basic features. But it doesn't solve the missed call problem.
Option 3: VoIP Phone System (RingCentral, Grasshopper, OpenPhone)
Cost: $20-$50/month per user Setup: 30 minutes to a few hours
Pros:
- Professional business number and greeting
- Call routing to multiple team members
- Business-hours scheduling
- Mobile app so you can take calls anywhere
- Call recording and analytics
Cons:
- Still requires someone to answer the phone
- After-hours calls go to voicemail unless you pay for add-ons
- Gets expensive with multiple users ($30-50/user/month)
- Requires some tech setup and management
- Auto-attendant menus frustrate callers ("Press 1 for...")
Popular options:
- Grasshopper: $14/month — best for solopreneurs wanting a second number
- OpenPhone: $15/month — clean app, good for small teams
- RingCentral: $20/month — full-featured but complex
Verdict: Good for small teams (3-10 people) who have at least one person available to answer during business hours. Doesn't solve the after-hours or busy-on-the-job problem.
Option 4: Traditional Answering Service
Cost: $200-$500/month Setup: 1-2 weeks
Pros:
- Real humans answer your phone
- 24/7 coverage available
- Can handle complex conversations
- Professional representation of your business
Cons:
- Expensive, especially with per-minute billing
- Operators don't understand plumbing/HVAC/electrical
- Long setup process (scripts, training, testing)
- Inconsistent quality depending on who answers
- Overage fees can blow up your bill
Verdict: Overkill for most small contractors. The cost doesn't justify itself until you're running a much larger operation.
Option 5: AI Answering Service
Cost: $29-$100/month Setup: 5-10 minutes
Pros:
- Handles 24/7 call coverage when forwarding and fallback rules are configured
- Captures detailed lead info automatically
- Flags urgent calls and routes them into your configured team workflow
- No per-minute billing; simple overage after included calls (at flat-rate providers)
- Sounds professional and natural
- Sets up in minutes, not weeks
- Understands trade-specific language (if purpose-built)
Cons:
- Not a full phone system (no internal team calling, extensions, etc.)
- Some callers may prefer a human (though most can't tell the difference)
- Newer technology — fewer providers than traditional options
Verdict: The best value for solo contractors and small crews who need their calls answered without hiring staff or paying call center rates.
The Recommended Setup for Small Contractors
Here's what I recommend based on team size:
Solo Contractor (Just You)
- Get a business number via Google Voice or Grasshopper ($0-$14/month)
- Add AI answering with OnCrew ($49/month)
- Total cost: $49-$63/month for a fully professional phone presence
This gives you a separate business number, professional call handling 24/7, lead capture, and emergency alerting — all for less than the cost of one pizza dinner per week.
Small Crew (2-5 People)
- VoIP system like OpenPhone ($15/user/month)
- AI answering for overflow and after-hours ($49/month)
- Total cost: $79-$124/month
Your team handles calls during the day, AI catches everything else.
Growing Operation (5-15 People)
- Full VoIP system like RingCentral ($20/user/month)
- Office manager or dispatcher handling daytime calls
- AI answering for after-hours and overflow ($49/month)
- Total cost: $149-$349/month + office manager salary
Don't Overcomplicate It
The best phone system is the one that ensures every call gets answered. For most small contractors, that means pairing a simple business number with an AI answering service.
