AI receptionist: a practical guide for business owners
Direct answer
An AI receptionist is software that answers your business phone with a synthetic voice, talks with the caller, answers common questions from information you give it, and takes down who called and what they need. Good ones say up front that they're an AI, admit when they don't know something, and hand anything that changes money or your schedule to a person. Prices run from free tiers and about $29 a month for simple answering up to several hundred dollars a month, and the bigger difference between products is what they're allowed to do on their own.
What an AI receptionist is
The job is the same one a person at a front desk does on the phone: pick up, find out why someone is calling, answer what can be answered, and make sure the right person hears about the rest. The AI version does this with speech recognition, a language model, and a generated voice, working from a script or a business brief you write.
It sits between two older options. A voicemail box is cheap and always on, but most callers hang up instead of leaving a message. A human answering service (Ruby, Smith.ai's live agents, and many local call centers) handles nuance well but charges by the minute or by the call. An AI receptionist answers every call, day or night, at a lower cost per call, and its weak spot is judgment.
If you're comparing the broader "front desk" idea that includes email and chat, our AI front desk guide covers that. This page is about the phone.
What a good one does on a call
Here's a normal call handled well:
- Discloses. "Thanks for calling [your business]. I'm an AI assistant. How can I help?" Callers should never have to guess.
- Finds the reason. New job, existing job, billing question, vendor, spam.
- Answers from the brief. Hours, service area, what you do and don't do, how estimates work. If the answer is in what you gave it, it says it plainly.
- Says when it doesn't know. "I don't have that information, but I can have someone call you back." This is the single most important behavior. A receptionist that guesses a price or an arrival time creates a promise you didn't make.
- Takes complete details. Name, callback number, address if relevant, what's wrong, how urgent, best time to reach them.
- Sets expectations. "I've passed this along, and someone will confirm." Not "you're booked for Tuesday" unless that's truly settled.
- Leaves a record. A transcript and a short summary you can read in a minute.
What it should never do alone
Some actions are cheap to undo and some aren't. A receptionist that books, quotes, or refunds on its own is making commitments on your behalf, and businesses have been held to what their bots said. In Moffatt v. Air Canada, a tribunal made the airline honor a refund policy its website chatbot described incorrectly.
Keep these behind a human OK:
- Quoting a price or discount
- Booking, moving, or canceling an appointment
- Refunds, credits, and payments
- Changing an order or account
- Promising an arrival time or a fix
- Anything legal, medical, or safety-related beyond "call 911" or "we'll have someone call you"
The receptionist can collect everything needed for those decisions. The decision itself should wait. We go deeper on this in human review for AI customer calls.
How to evaluate an AI receptionist
Run any product through these questions before you forward a single call:
- Does it say it's an AI? Ask whether disclosure is on by default and whether you can turn it off. You want it on.
- What does it do when the answer isn't in its information? Call it yourself and ask something you never told it. Listen for a guess.
- What can it do without you? Booking straight into your calendar is convenient, until it double-books or books a job you'd have declined. Know the setting.
- How do you see what happened? Transcripts, summaries, and alerts for urgent calls.
- What happens after hours and when it misses? Voicemail, a text to you, or nothing.
- How is it priced? Per minute, per call, per unique caller, or flat. Work it out at your real call volume, including your busy season.
- Who sets it up? Self-serve tools are cheaper but you write the script and test it. Done-for-you costs more and gets you a working setup faster.
The main kinds, with real examples
Prices below are from each vendor's own pricing page as of October 2026. Check the page before you buy, because these change often. The table shows one example of each kind. For a vendor-by-vendor roundup, see best AI receptionist options compared.
| Option | Type | Starting price | How it bills |
|---|---|---|---|
| Dialzara | Self-serve AI receptionist | $29/mo for up to 60 minutes | Minutes, $0.48/min over on that plan |
| Smith.ai AI Receptionist | AI with optional live agents | Free for 25 calls/mo, Pro $150/mo for about 60-90 calls | Per call |
| Ruby | Human receptionists | $250/mo for 50 minutes | Minutes |
Self-serve AI receptionists
Dialzara, Rosie, My AI Front Desk, and Goodcall are built for a small business to sign up, enter its information, forward its number, and go. They're the cheapest way to stop sending calls to voicemail. Many of them can book directly into a calendar and transfer calls live, which is useful if you're comfortable with the AI making those calls. They're a good fit for a solo operator who mostly needs messages taken and basic questions answered.
AI with humans behind it
Smith.ai sells both an AI receptionist and live human receptionists, and lets you add live-agent help per call. That's a real advantage when some calls need a person. Our Smith.ai review covers it in more detail.
Human answering services
Ruby and similar services still do the best job on emotional, complicated, or high-value calls. You pay for it: Ruby's smallest plan is 50 minutes for $250 a month. See AI receptionist vs answering service for the tradeoffs.
Developer platforms
Vapi, Retell, and Bland let a developer build a custom voice agent and pay per minute. Powerful, but you're building and maintaining it. Our AI voice agent guide covers who should go that route.
Where TeamShift fits
TeamShift answers your business line with an AI voice agent, day, night, and weekends. You forward your number or use one TeamShift sets up, and TeamShift's team sets it up for your business. It tells every caller it's an AI assistant at the start of the call. It answers callers from a business brief you write (hours, services, service area, policies) and doesn't look things up in your tools for them. When something isn't in the brief, it says so and offers a callback.
It takes messages and job details. Anything that would change something, like booking or moving an appointment, a quote, a refund, a payment, or an order change, isn't done on the call. It comes to you as a request to approve, and the caller is told someone will confirm. Missed and after-hours calls go to voicemail with a text alert to you, and callers who call back reach the same agent. Each call has a record (outcome and notes) in TeamShift. Only you, after you call in and read back a code texted to your phone, can have it look things up in your connected tools.
The phone is one part of a larger team. The Support worker also sorts your email and drafts replies and missed-call texts for your OK, and the rest of the team prepares quote, invoice, and follow-up work for your approval. Billing is by usage: a free workspace, work billed at 3x its compute cost, and a maximum quoted before it starts. See pricing.
What it doesn't do: transfer a live call to you, take calls in other languages, or book directly into your calendar mid-call. If you need live transfers or a person on emotional and complex calls, a service like Smith.ai or Ruby is the better choice. Some callers won't talk to an AI at all. They should be offered voicemail or a callback, and with TeamShift they are.
FAQ
What is an AI receptionist?
It's software that answers your business phone with a synthetic voice, handles common questions from information you provide, and takes messages and job details. Good ones disclose they're an AI and pass decisions about money or your schedule to a person.
How much does an AI receptionist cost?
As of October 2026, self-serve plans start around $29 to $99 a month on vendor pricing pages, with per-minute, per-call, or per-caller charges above the included amount. Smith.ai offers a free tier for 25 calls a month. Human answering services cost more per call.
Do callers know they're talking to an AI?
They should. Pick a product that discloses at the start of every call. Callers who don't want to talk to an AI should be offered voicemail or a callback.
Can an AI receptionist book appointments?
Many can book straight into a calendar. Whether you want that depends on how often a booking needs your judgment. A safer setup takes the request on the call and confirms it after a person approves.
Is an AI receptionist better than a human answering service?
It's cheaper per call and never busy, and it's good at routine calls. A person is still better for upset callers, complicated situations, and sales conversations. Some businesses use both.
