Phone ringing while you’re with a client. Missed call. Lead gone.
An AI receptionist answers your line, works out the ask, then books, transfers, or takes a message. At about 200 short calls a month, turnkey plans we checked land near $150 to $400. A live answering service for the same talk time starts near $720.
We pulled public pricing on 6 November 2026 and ran the maths. No live call-centre tests. The catch is the billing unit: per call, per minute, or human minutes.
What an AI receptionist is (and what it isn’t)
Think front-desk hire that never sleeps, not a press-1 phone tree.
A packaged AI receptionist greets in natural language, answers FAQs you trained, qualifies the lead, books when the plan allows, texts a link, or warms a transfer to your phone. Smith.ai and Rosie sell that job as a product.
Search results mix three neighbours:
- IVR / phone tree. “Press 1 for sales.” Fine for routing. Weak for booking a cut at 7pm.
- Human answering service. A live person (Ruby is the classic). Best when tone beats price.
- Voice AI platforms. Retell and Vapi let you build any phone agent. A receptionist is one build. See our Retell review and Vapi review.
If you buy through those /go/ links, we may earn a commission. It does not change the numbers below.
Video avatars (our HeyGen avatar video tutorial, via HeyGen) talk on camera. They do not sit on your inbound number.
How a call actually flows
Most products share four beats, even when the UI looks different.
- Answer. Pick up in one or two rings with your greeting.
- Intent. Ask why they called; match FAQ, spam, or a booking request.
- Act. Book a slot, send an SMS link, take a structured message, or warm-transfer with a short brief.
- Log. Transcript, summary, and a CRM or email ping.
Under the hood this is the same voice loop as other generative tools: speech in, model decides, speech out. Our generative AI explainer covers that pattern. The receptionist product wraps it with telephony, calendars, and transfer rules so you are not wiring SIP at midnight.
Our take: if the vendor cannot show transfer and booking in a demo call, you are buying fancy voicemail.
Where they shine, and where they fail
After-hours and overflow are the easy wins. Nights, lunch, and a flooded second line are where missed calls turn into reviews.
Best for: solo clinics, salons, law intake, and home services that need 24/7 capture with a short script. FAQs, appointment links, and “hold while I get the owner” transfers.
Not ideal for: clinical triage that needs a licensed person, multi-provider calendars with room conflicts, bill fights, or anything that must never invent a policy. Those stay with a human service or your staff.
Platforms help when you already have builders. The gap between a packaged receptionist and a DIY agent mirrors AI agents vs automation: one ships a job, the other ships a toolkit.
What a month really costs for 200 calls
For a clinic with 200 answered calls at about 2 minutes each (400 minutes), turnkey AI sits well under a live service. DIY platforms undercut both on raw minutes.
Every price above was checked on 6 November 2026. We did not log into dashboards or place test calls.
| Path | How it bills | Fit for 200 × 2 min | Est. month |
|---|---|---|---|
| Rosie Scale | Minutes in a plan | 1,000 min included | $149 |
| Smith.ai Pro 150 | Per call | $270 + 50 × $2.30 | $385 |
| Smith.ai Pro 300 | Per call | 300 calls included | $500 |
| Retell DIY (~$0.15/min) | Components per minute | 400 min + $2 number | ~$62 |
| Ruby (human) | Receptionist minutes | Closest published plan covering 400 min is 500 | $1,725 |
Catches the table hides:
- Smith.ai Free is $0 for 25 calls, then $3 each. At 200 calls that is $525. Fine to trial. Harsh as a plan.
- Rosie Professional is $49 with 250 minutes and no live calendar booking or warm transfer. Our 400-minute clinic needs Scale.
- DIY on Retell or Vapi looks cheap until you own prompts, calendar wiring, spam rules, and 11pm transfer failures. Voice often leans on stacks like ElevenLabs (see ElevenLabs pricing and our ElevenLabs review).
- Long calls favour minute plans. Short qualification calls favour per-call plans. Count average length before you pick.
Dialpad and other phone suites bury AI agents inside seat pricing. Useful if you already live there. Not a clean sticker for this sheet, so we left them out of the maths.
Buying checklist before you swipe a card
- Count answered calls for a month, plus average talk time.
- Write five intents: book, reschedule, new lead, existing client, emergency escalate.
- Demand a live transfer demo to your mobile, with a spoken handoff.
- Ask what counts as billable (spam, short hangups, transfers).
- Check calendar and CRM hooks you already use.
- Know the human backup. Hybrid AI-plus-live costs more per call and still beats a full human desk for many offices.
- Start after-hours only for two weeks. Measure bookings and angry callbacks before you change daytime coverage.
How we checked (and what we did not)
On 6 November 2026 we pulled prices from Smith.ai’s AI Receptionist page, Rosie’s pricing page, Ruby’s plans page, Retell’s pricing page, and Vapi’s pricing page. Then we ran the 200-call clinic sheet above.
We did not place mystery shopper calls, measure latency, or rate accent handling. If a vendor changes a tier tomorrow, trust their live page and re-run the same maths.
Frequently asked questions
Is an AI receptionist the same as a virtual receptionist?
Not always. Virtual receptionist often means a live human answering service. An AI receptionist is software that answers in a trained voice. Some vendors sell both, or a hybrid that escalates to a person when the bot is stuck.
Can an AI receptionist book appointments on my calendar?
On mid and upper plans, yes, when the vendor supports your calendar. Entry plans sometimes only text a booking link. Confirm Google Calendar, Outlook, or your practice tool in a demo before you pay.
Will spam and robocalls burn my call allowance?
It depends on the vendor. Smith.ai says known spam is filtered before answer and lets you remove up to 10 percent of calls from a bill. Always ask how hangups and robocalls are counted.
Is DIY with Retell or Vapi cheaper than Smith.ai or Rosie?
On raw minutes, usually yes. A 400-minute month can land near $50 to $100 on a platform. You still own prompts, telephony quirks, and after-hours failures. Buy turnkey if you want a product, not a project.
Do AI receptionists work for medical or dental offices?
They work for scheduling and intake scripts. They should not give clinical advice. Ask about HIPAA or BAA options, recording rules, and a human escalate path for emergencies before go-live.
What happens when the caller wants a human right away?
A good setup offers a warm transfer with a short brief, or a callback promise. If the product can only take a message, daytime callers will bounce. Test that path on day one.
Should I replace my front-desk person with an AI receptionist?
Rarely as a first move. Use it for nights, lunch, and overflow first. Keep a human for walk-ins and hard conversations. Cut staff only after two quiet months of measured results.
How is an AI phone receptionist different from a chat bot?
The channel is different. Phone agents deal with accents, barge-in, hold music, and PSTN quirks that website chat never sees. Some vendors sell both products. Treat price and quality as separate buys.
Bottom line
If you run a small office and hate missed after-hours leads, buy a packaged AI receptionist and start on nights. For about 200 short calls a month, expect roughly $150 to $400 on turnkey plans we checked, far under a live desk at the same talk time.
Pick DIY platforms only when someone can own the agent. Pick a human service when judgement beats cost. Count your calls, demand a transfer demo, and re-check the vendor page before you renew.
