It's 11:47 p.m. on a Friday. A driver just rear-ended someone on the highway and is searching for a personal injury attorney on their phone. They call three firms from Google. The first goes to voicemail. The second rings out. The third — your firm — answers immediately, takes their information, and books a Monday morning consultation.
That scenario plays out thousands of times every night across North America. The firm that wins the case isn't necessarily the best firm — it's the one that picked up. This is the central argument for AI receptionists. But the decision isn't that simple, and any honest comparison has to acknowledge where live receptionists still hold the advantage.
This article breaks down the real numbers on cost, availability, quality, and fit — so you can make an informed decision rather than being sold by a vendor's marketing copy.
42% of legal inquiries arrive outside standard business hours — evenings, weekends, and holidays. For personal injury and criminal defense firms, that figure climbs above 50%. A receptionist who clocks out at 5 p.m. is invisible to nearly half of your potential clients. (Source: Clio Legal Trends Report, 2025)
The Real Cost Comparison
Let's start with the number every managing partner cares about: what does this actually cost?
Live Receptionist: The True All-In Number
A full-time in-house receptionist in a major North American market earns $38,000–$52,000 in base salary. Add employer payroll taxes (roughly 7.65%), health insurance contributions ($300–$600/mo), paid time off, training time, and equipment — and the real annual cost runs $48,000–$68,000, or $4,000–$5,667 per month.
Law firms that outsource to a live answering service rather than hiring in-house typically pay $1.50–$3.50 per minute of call time, plus monthly base fees. A firm receiving 400 minutes of calls monthly pays $600–$1,400 for the answering service alone — but that service only operates defined hours, and weekend/overnight rates are 40–80% higher.
The hidden cost: missed calls still happen. Even 24/7 live answering services average 15–45 second hold times, and 12–18% of callers hang up before being answered during peak periods. Each missed personal injury call represents a potential case worth $5,000–$50,000 in contingency fees.
AI Receptionist: What You Actually Pay
AI receptionist platforms designed for law firms — Smith.ai, Ruby, Answering Legal, and others — have pricing structured around call minutes or message volume. Entry plans covering 100–200 calls per month run $300–$500/mo. Mid-tier plans with Spanish-language support, CRM integration, and higher call volumes sit at $600–$1,000/mo. Enterprise plans with full customization and unlimited minutes reach $1,200–$1,500/mo.
Unlike live staff, the cost does not scale with hours of availability. A $500/mo AI receptionist works the same number of hours whether you pay $500 or $5,000.
A personal injury firm switching from a $4,200/mo in-house receptionist to a $700/mo AI receptionist + $400/mo part-time intake coordinator saves approximately $37,200 per year while improving after-hours coverage from 0% to 100%.
