The Real Cost of a Human Receptionist at a Law Firm
When law firm partners think about replacing their receptionist with an AI system, the initial reaction is often "but the receptionist only costs $45,000/year." The actual total cost of a full-time receptionist is significantly higher, and the comparison to AI systems changes dramatically when you account for every cost line.
| Cost Category | Annual Cost |
|---|---|
| Base salary (legal receptionist, US average) | $40,000–$52,000 |
| Payroll taxes (FICA, FUTA, SUTA ~15%) | $6,000–$7,800 |
| Health insurance (employer contribution) | $6,000–$12,000 |
| Paid time off (15 days avg = 6% of salary) | $2,400–$3,120 |
| Training and onboarding | $1,500–$3,000 (Year 1) |
| Turnover cost (avg 1.5–2× salary when replaced) | $3,000–$8,000/year prorated |
| After-hours coverage gap (zero after 5 PM) | Revenue opportunity cost: $50,000–$200,000 |
| Total Annual Cost | $59,000–$86,000 (+ opportunity cost) |
The Real Cost of an AI Voice Reception System
| Cost Category | Annual Cost |
|---|---|
| Custom AI voice system build (one-time) | $2,400–$4,800 setup |

| Telephony infrastructure (Twilio/Vapi) | $1,200–$2,400/year |
| Ongoing maintenance and optimisation | Included in retainer |
| After-hours coverage | 100% — 24/7/365 |
| Total Annual Cost | $8,400–$16,800/year |

The Hybrid Model: Best of Both Worlds
Most law firms we work with don't replace their receptionist entirely. Instead, they deploy the AI system for:
- All after-hours calls (100%)
- Overflow during peak hours when the human is busy
- Initial intake qualification before transferring to the human for complex discussions
This hybrid approach typically costs $6,000–$10,000/year in AI infrastructure while allowing the human receptionist to focus on higher-value relationship work — and the firm captures all the after-hours revenue it was previously losing.
Net result: Same receptionist salary, $8,000–$12,000 in AI infrastructure, and $50,000–$150,000 in recovered after-hours revenue. The ROI math is not subtle.
