An AI receptionist is the cheaper way to answer simple, predictable calls: opening hours, directions, booking a standard appointment, routing to the right person. At Smith.ai, AI-first plans cost roughly $1.60–$2.00 per call, against $7–$10 per call for its human receptionists (as of October 30, 2026). A human is the better choice when the call involves money, identity, legal or medical detail, an upset caller, or a judgement the script didn't anticipate. Consumer surveys keep saying the same thing: people will use AI for simple things, but they want a human within reach. For most small businesses the answer is a hybrid. Let AI take the routine and after-hours calls, and make sure a real person picks up when a call needs one.
Searches for "ai receptionist" in the US went from about 5,400 a month in July 2026 to 450,000 in September (Google Ads Keyword Planner). Over the same year, searches for "virtual receptionist" fell from 8,100 to 1,900. Plenty of owners are asking the question. This guide answers it without selling either side.
- US small-business owners (practices, agencies, home services, salons, law and accounting firms) deciding who should answer the phone
- Office managers comparing an AI answering service with a live receptionist service on price
- Medical, dental and legal practices that need to know what HIPAA and intake rules mean for each option
- Owners already using an AI receptionist who want to know when to put a person behind it
Zedtreeo places dedicated human virtual receptionists and builds AI receptionists for clients, so we have a stake on both sides. Every figure below comes from the vendor's or regulator's own page, and we point out where each option is the better buy.
What we're comparing
| AI receptionist | Human virtual receptionist | |
|---|---|---|
| What it is | Software (also sold as an AI answering service or automated receptionist) that answers your line with a synthetic voice, understands the request, and follows rules you set: answer FAQs, book, route, take a message | A trained person answering your line, either from a shared answering service or as a dedicated receptionist who works only for you |
| Typical pricing | Per call or per minute; low unit cost | Per call or per minute (shared services), or a flat monthly rate (dedicated) |
| Hours | 24/7 by default | Shared services often 24/7; a dedicated person covers their shift, and 24/7 needs a rota |
| Gets better by | Better scripts, knowledge base and integrations | Learning your business, clients and judgement calls |
There are two kinds of human service. Shared answering services (Ruby, Smith.ai's human tier) give you a pool of receptionists who answer for many businesses. Dedicated virtual receptionists are one person on your line during your hours, logged into your calendar and CRM. They cost and feel different, and both appear below.
How much does each option cost? (as of October 30, 2026)

Human receptionist, shared service: Smith.ai and Ruby
| Service | Plan | Price | Effective rate |
|---|---|---|---|
| Smith.ai human-first | Starter | $300/mo, 30 calls | $10/call (overage $11.50) |
| Smith.ai human-first | Basic | $810/mo, 90 calls | $9/call (overage $10.50) |
| Smith.ai human-first | Pro | $2,100/mo, 300 calls | $7/call (overage $8.50) |
| Ruby | 50 minutes | $250 | ~$5.00/min |
| Ruby | 100 minutes | $395 | ~$3.95/min |
| Ruby | 200 minutes | $720 | ~$3.60/min |
| Ruby | 500 minutes | $1,725 | ~$3.45/min |
Sources: Smith.ai receptionist pricing, Ruby plans and pricing. Smith.ai human plans charge the same for calls at 2 am and 2 pm. They add per-call extras: booking $1.50, payments $1.00, complex routing $1.50, Spanish line $1.00, recording $0.25. Ruby sells only live human answering. It uses AI features (transcripts, call lookup, robocall filtering) to support its receptionists, includes them in every plan, and says it does not use AI to replace the human (Ruby AI).
Ruby bills per minute and Smith.ai per call, so you can't compare their rates directly without knowing your average call length.
Human receptionist, dedicated: a flat monthly seat
A dedicated receptionist is billed by time, not by call. Zedtreeo's start at $6/hour, or $1,056 for a 176-hour month (virtual receptionist service). The price is the same whether the phone rings 40 times a day or 4. That's Zedtreeo's own price, not a market average; we have no verified industry figure for offshore dedicated receptionists.
AI receptionist, custom-built: priced by build time
The third route is an AI receptionist built for your business, inside your own phone, calendar and CRM accounts, instead of a shared product. There's no per-call price. You pay for the engineer's time to build and tune it (Zedtreeo's Forward Deployed Engineers start at $10–12/hour), and you pay the phone and voice providers directly for usage. It makes sense when an off-the-shelf plan can't follow your booking rules or reach your systems. For a simple FAQ-and-booking line, a packaged plan like the ones above is usually cheaper.
What the numbers mean at different call volumes
| Calls per month | Smith.ai AI-first | Smith.ai human-first | Dedicated seat ($1,056 flat) |
|---|---|---|---|
| 75 | $150 | ~$810+ | $1,056 |
| 150 | $270 | ~$1,400–1,600 | $1,056 |
| 300 | $500 | $2,100 | $1,056 |
| 600 | ~$1,100 (plan plus overage) | ~$4,600 | $1,056 |
How we worked it out: the rates are the published plan prices above, with overage at the listed per-call rate. The human-first column ignores per-call add-ons, so the real figure is higher. The dedicated column assumes the calls fall within one person's working hours. Some calls will escalate from AI to a human, which raises the AI cost. A third-party model of 200 calls with 20% escalated put AI-first at about $505 against $1,965 all-human (Macha, Sep 2026; Macha sells a competing AI product).
What it shows: at low volume, AI is far cheaper than any human option. At a few hundred calls a month, a dedicated person costs about the same as AI per call and much less than a shared human service, because the seat is flat-rate. What the dedicated seat doesn't give you is 24/7 coverage for $1,056; round-the-clock cover needs two or three people on a rota.
What does an AI receptionist handle well?
The evidence points to the same pattern each time: AI works when the call is predictable and the stakes are low.
- FAQs: hours, location, parking, services offered, whether you're accepting new clients.
- Simple bookings into a calendar with clear rules ("30-minute consultation, weekdays, 9–5").
- Routing: "press nothing, just say who you need" and a transfer.
- After-hours and overflow: a polite answer instead of voicemail at 11 pm or when three calls arrive at once.
- Status checks: "Is my appointment still on?" "Did you get my documents?"
Consumer surveys back this up. In Five9's 2026 Consumer CX Report, consumers were most willing to let AI act alone on simple account tasks like password resets (38%) and order or account status (35%) (Five9, Oct 14 2026). SurveyMonkey found 65% of US adults are fine using AI to order food and 59% to return an item (SurveyMonkey, Dec 2025).
Where do AI receptionists struggle?
- Anything involving money, identity, legal or high stakes. In the same Five9 study, the share of consumers who want a human was 45% for refunds, 50% for charge disputes, 51% for identity verification, 54% for legal compliance and 60% for high-stakes escalations.
- Being misunderstood. Among people who switched from AI to a human, 46% said the bot repeatedly misunderstood them, rising from 38% of Gen Z to 59% of baby boomers (Five9). For a practice or a law firm with older callers, that matters.
- No way out. 87% of customers say a route to a human is essential when a company uses GenAI for service (Gartner, Aug 2026). Only 27% would try a chatbot again after a bad experience (Gartner, Sep 2026).
- Patience runs out quickly. 92% give an AI agent under 10 minutes before trying to reach a person (Five9). 84% give a virtual agent three attempts or fewer (Genesys, Jul 2026).
- Outcomes. 46% of US and UK adults say AI customer service rarely or never ends in a successful outcome (Pega/YouGov, Feb 2026).
every survey here measures attitudes to AI customer service in general (chatbots, phone and chat together), and several include non-US respondents. No independent study we found measures how accurately AI phone receptionists book appointments, or how they cope with accents and noisy lines. Treat vendor accuracy claims as marketing until you've tested them on your own calls.
When is a human virtual receptionist worth the cost?
- New-client intake that needs judgement: a legal intake that has to spot a conflict, or a dental caller describing pain that should jump the queue.
- Upset or confused callers. A person can slow down, reassure, and decide when to bend the script.
- Calls that span systems: checking the calendar, the CRM and a note from yesterday before answering.
- Callers who want a person. 79% of US adults say they prefer a human to an AI agent; 8% prefer AI (SurveyMonkey).
- The same voice every time, with a dedicated receptionist. Regular clients get to know who answers.
What it costs you: a higher price per call on a shared service, or fixed coverage hours with a dedicated seat. And a human gets tired and needs breaks, holidays and backup.
The compliance points to check first
1. HIPAA (medical, dental and therapy practices)
Under HHS guidance, any answering vendor (AI or human) that creates, receives or keeps patient information is a HIPAA business associate. That covers storing call recordings, transcripts, messages or booking details. A practice may share patient information with it only after a Business Associate Agreement (BAA) is signed. The narrow "conduit" exception covers only services that pass data through with temporary storage incidental to transmission (HHS: cloud providers and the conduit exception; HHS: business associates, reviewed Oct 2026). HHS gives a third-party chatbot that schedules appointments with patient information as an example of a business associate. An AI phone receptionist works the same way.
In practice: ask any AI or human answering vendor for a signed BAA before the first patient call. Zedtreeo signs one before any patient data is touched (medical receptionists).
2. The FCC's AI-voice ruling (TCPA)
In February 2024 the FCC ruled that AI-generated voices count as "artificial or prerecorded voice" under the TCPA. Calls using them need the called party's prior express consent, and written consent for telemarketing (FCC 24-17). The ruling is about outbound calls. It doesn't regulate an AI answering calls a customer placed. But if your AI receptionist also makes outbound calls (appointment reminders, callbacks, re-booking), those calls fall under the ruling. Get consent and keep the records.
3. Call recording
Many AI receptionists record and transcribe every call by default, and some US states require every party to consent to a recording. The rules vary by state, so check the law where you and your callers are, and use a disclosure line ("this call may be recorded") whichever option you choose.
What does a hybrid AI-plus-human setup look like?
The cost gap and the consumer data point the same way:
- AI picks up first for hours, directions, simple bookings and after-hours calls.
- The caller can always reach a person: "say 'person' at any time". When people can see that option, trust that AI will resolve their issue rises from 26% to 55% (Five9).
- The handover carries the context. 35% of consumers often or always have to repeat themselves after a handoff (Five9), which is the fastest way to lose the goodwill the AI just earned.
- A human handles anything involving money, identity, legal or medical detail, or an upset caller, by rule, not when the AI happens to give up.
The economics still work. Even if one call in five escalates, the hybrid costs far less than all-human answering. Smith.ai's AI calls cost about $2–2.50, against $7–10 per call for its human tier.
There are three ways to put a hybrid together:
- Buy both halves as one product. Smith.ai sells AI-first plans with human backup. It's the quickest to set up and works best when your calls are standard.
- Buy an AI plan and a human separately. An off-the-shelf AI receptionist takes first line, and a dedicated receptionist on your hours takes the escalations.
- Have the AI built for you and pair it with a person. A Forward Deployed Engineer builds the AI receptionist in your own accounts, following your rules, and a dedicated receptionist takes the calls it hands over. This is the setup we run ourselves.
Try one yourself
The fastest way to judge an AI receptionist is to call one. Zedtreeo's own front desk is an AI receptionist called Neil, which we built and run. Call (781) 734-7890 at any hour. Ask about pricing, ask for a meeting, leave a message, or ask for a person, and see how it copes.
While you're on the call, test the things this guide says matter:
- Does it understand you the first time, including when you rephrase?
- Can you reach a person without a fight?
- When it books something or takes a message, does it get the details right?
We label the line as AI wherever we publish it. Anyone who'd rather talk to a person can call the team on (725) 977-3776.
How to decide: a quick checklist
| If this describes you… | Lean towards |
|---|---|
| Under ~5 calls a day, mostly simple questions | AI receptionist, or a shared service on a small plan |
| Calls mostly after hours | AI receptionist for after-hours, human in the day |
| Many calls involve intake, quotes, payments or worried people | Human (shared or dedicated), with AI for overflow |
| Medical, dental or legal practice | Human first; any vendor must sign a BAA (medical) and handle intake carefully |
| Several hundred calls a month during business hours | Price a dedicated receptionist; the flat seat often costs less than per-call human service |
| You need 24/7 coverage on a tight budget | AI overnight + human in business hours |

How we researched this
We compiled this guide on October 30, 2026. Prices come from the vendors' own pricing pages that day. Consumer attitude figures come from the primary releases of Five9, Gartner, Genesys, Pega/YouGov and SurveyMonkey; most are commissioned by companies that sell customer-service software, and several cover non-US consumers. Regulatory points come from the FCC ruling and HHS guidance. Search-volume figures are US monthly averages from Google Ads Keyword Planner. We left out claims we couldn't verify on a primary source, including published prices for other AI-only vendors and any per-call accuracy figures for AI phone agents.
Frequently Asked Questions
Is an AI receptionist cheaper than a human?
Per call, yes, often by four or five times. Smith.ai's AI-first plans cost about $1.60–$2.00 per call against $7–$10 for its human tier (October 30, 2026). A dedicated human on a flat monthly rate narrows the gap at higher call volumes.
Can an AI receptionist book appointments?
Yes, when the booking rules are simple and it's connected to your calendar. Watch for calls that don't fit the rules (urgent cases, unusual requests, multi-person bookings) and make sure those reach a person.
Do callers mind talking to AI?
For simple tasks, many don't. For money, identity, legal or high-stakes matters, most want a person, and 87% say a route to a human is essential (Gartner, 2026).
Is an AI receptionist HIPAA compliant?
Only if it's set up correctly and the vendor signs a BAA. Under HHS guidance, an answering vendor that stores recordings, transcripts or booking details for a practice is a business associate.
Does the FCC's AI voice rule apply to an AI receptionist?
The 2024 ruling covers AI voices in outbound calls. Answering calls doesn't fall under it, but reminder and callback calls made by the AI do.
Should I tell callers they're talking to AI?
It builds trust, and offering a human makes AI more acceptable: trust roughly doubles when a person is reachable (Five9). If the system records calls, tell callers that too.
What's the difference between an answering service and a dedicated virtual receptionist?
An answering service shares a pool of receptionists across many businesses and bills per call or per minute. A dedicated receptionist works only for you, on your hours and systems, for a flat monthly rate.
Can Zedtreeo build an AI receptionist for my business?
Yes. A Forward Deployed Engineer builds it in your own phone, calendar and CRM accounts, so your call data stays in systems you control, and can pair it with a dedicated human receptionist who takes the calls it hands over. You can call Neil, the AI receptionist we built for our own front desk, on (781) 734-7890 to hear what that looks like (how the engineer role works).
