AI Voice Agent vs Human Receptionist: Cost Analysis for Plumbing
Compare the true cost of AI voice agents vs human receptionists for plumbing businesses. Includes salary, benefits, training, and opportunity cost analysis.
The True Cost of Answering Phones in Plumbing
For most plumbing businesses, the phone is the primary revenue channel. But staffing it properly is expensive — and understaffing it costs even more in lost opportunities.
Human Receptionist Costs
A full-time receptionist for a plumbing business typically costs:
| Cost Component | Annual Cost |
|---|---|
| Base salary | $32,000 - $45,000 |
| Benefits (health, PTO, etc.) | $8,000 - $15,000 |
| Training & onboarding | $2,000 - $5,000 |
| Turnover replacement (avg 1x/year) | $4,000 - $8,000 |
| Phone system & equipment | $1,200 - $3,000 |
| Total annual cost | $47,200 - $76,000 |
And that is for a single employee covering ~40 hours per week. For 24/7 coverage, you need 4-5 FTEs — pushing annual costs to $190,000 - $380,000.
What Human Receptionists Cannot Do
Even the best receptionist:
- Cannot answer multiple calls simultaneously
- Needs breaks, sick days, and vacation
- Varies in quality based on mood and energy
- Cannot instantly access all business systems
- Requires continuous training on new procedures
