Every small business owner knows the feeling. The phone rings while you're with a customer, on a job, or closing up for the day, and by the time you call back, they've booked with someone else.
An AI receptionist fixes that. It picks up every call, answers the questions you get all day, books appointments straight into your calendar, and hands the rest to you with a summary. This guide covers what it handles, what it costs next to a person, and how to work out what it's worth to your business before you spend anything.
Key takeaways
- An AI receptionist answers every call, day and night, and handles questions, bookings, reschedules, messages, and transfers.
- Running costs are about $0.11 to $0.25 a minute. 300 three-minute calls a month comes to about $99 to $225.
- A full-time receptionist costs about $54,300 a year with benefits and covers 40 of the week's 168 hours.
- The real value is in missed calls. 60 missed calls a month on $400 jobs can be over $7,000 a month in lost work.
- Start with after-hours and overflow calls, then widen it once it's handling those well.
What is an AI receptionist?
An AI receptionist is an AI voice agent that answers your business phone, talks with callers in a natural voice, and does what a front desk does. It answers questions, books appointments, takes messages, and transfers calls to the right person.
It isn't a phone menu. Callers don't press 1 for sales. They just say what they need, the way they would to a person, and it responds.
What an AI receptionist handles
Most small businesses get the same handful of calls over and over. Those are exactly what an AI receptionist is good at.
| Call | What the AI receptionist does |
|---|---|
| "Are you open Saturday?" | Answers from your hours, service area, prices, and policies |
| "I'd like to book an appointment" | Checks your calendar, offers open slots, and books it |
| "I need to move my appointment" | Finds the booking, reschedules or cancels it, and confirms |
| A new customer asking about a job | Asks your qualifying questions and books them or passes them on |
| "Can I talk to the owner?" | Takes a message and texts or emails you a summary |
| An urgent problem | Transfers the call to you or your on-call person right away |
After every call, you get a short summary with the caller's name, number, what they wanted, and what happened. So nothing gets lost between the phone and your calendar.
What it should hand to a person
A good setup knows its limits. Send these to a person every time.
- Upset customers. Someone with a complaint wants to be heard by a person.
- Custom quotes. If the price depends on looking at the job, the AI books the visit and you quote it.
- Payments. Take card details through a secure payment link or in person, not over an AI call.
- Anything sensitive. Medical, legal, or financial advice stays with your team.
The handoff is where most setups go right or wrong. When the AI transfers a call, the person picking up should already know who's calling and why, so the caller never has to repeat themselves.
What an AI receptionist costs
An AI receptionist costs about $0.11 to $0.25 a minute to run, plus the setup and monthly upkeep of the system. The per-minute cost is made up of the voice platform, the AI model, the voice, and the phone line.
Here's how those parts add up on Retell AI's price list (opens in a new tab), with US calls through Twilio (opens in a new tab).
| Part | Lean setup | Premium setup |
|---|---|---|
| Voice platform | $0.055 | $0.055 |
| AI model | $0.024 | $0.08 |
| Voice | $0.015 | $0.10 |
| Phone line | $0.015 | $0.015 |
| Per minute | About $0.11 | About $0.25 |
The difference between the two is mostly the voice and the model. For booking appointments and answering common questions, the lean setup usually sounds and works fine. For a high-end service where the call is the first impression, the premium voice can be worth it.
At 300 calls a month averaging three minutes, the call costs come to about $99 a month on the lean setup and $225 on the premium one. For more on platforms and per-call plans, see what an AI voice agent costs.
AI receptionist vs a human receptionist
The median US receptionist earns $18.27 an hour (opens in a new tab), or $38,010 a year. In private industry, benefits add another 30% (opens in a new tab) on top of wages on average. That puts a full-time receptionist at about $54,300 a year, or $4,525 a month.
| Human receptionist | AI receptionist | |
|---|---|---|
| Hours covered | 40 a week | All 168 hours a week |
| Monthly cost | About $4,525 | About $99 to $225 in calls, plus upkeep |
| Calls at once | One | Several at the same time |
| Sick days and vacations | Someone has to cover | No gaps |
| Cost per call at 300 calls a month | About $15 | About $0.33 to $0.75 |
The hours row is the one that matters most. A full-time receptionist covers 40 of the week's 168 hours, which is less than a quarter. Covering every hour with people would take more than four full-time staff, or about $228,000 a year.
For most small businesses, this isn't about replacing anyone. If you have a receptionist, the AI takes the calls they can't get to, like the second line when they're already on the phone, lunch breaks, evenings, and weekends. If you don't have one, it's the front desk you couldn't justify hiring.
What your missed calls are worth
This is the number that decides whether an AI receptionist is worth it. It takes three numbers from your own business.
Your phone system or carrier can show you missed calls. Look at three months, and note when they happen. Say you miss 60 calls a month and 30% of those callers would have booked.
| Average job value | Lost work per month | AI cost to answer those 60 calls |
|---|---|---|
| $150 | $2,700 | About $45 |
| $400 | $7,200 | About $45 |
| $1,000 | $18,000 | About $45 |
That last column is the running cost at the premium rate of $0.25 a minute for three-minute calls. Even on the smallest jobs, the calls it saves are worth about 60 times what they cost to answer.
Don't stop at the count, either. Check when the missed calls happen. If most come in after 5pm and at lunch, you already know where the AI receptionist should start.
How to set one up
You don't have to switch everything over on day one. The setups that work best go live in stages.
- List why people call. Go through your last 50 calls or messages and group them by reason. A handful of reasons usually covers most of them.
- Write down the answers. Hours, service area, prices, policies, and what you ask a new customer. This becomes what the AI receptionist knows.
- Connect your calendar. Set which appointment types it can book, how long each takes, and how much notice you need.
- Decide the transfer rules. Who gets urgent calls, at what hours, and what happens when nobody picks up.
- Start with after-hours and overflow. Forward calls to the AI receptionist when nobody answers and when you're closed. Your team keeps every call they already take.
- Review the first few weeks of calls. Listen to a sample, fix anything it got wrong, and add answers for questions you missed.
- Widen it. Once it's handling overflow well, let it take more calls, or all of them.
Your phone number stays the same through all of this. Calls forward to the AI receptionist based on the rules you set.
Rules for recording and AI calls
Most AI receptionists record calls so you can review them. US federal law allows recording when one party to the call consents (opens in a new tab), but several states, including California, Florida, Pennsylvania, and Washington, require everyone on the call to agree. The simple fix is to have the AI receptionist say at the start that the call is recorded.
Have it say it's an AI assistant too, and make sure callers can ask for a person at any time. It's honest, and it sets the caller's expectations from the first sentence. This is a summary for planning, not legal advice for your state.
If you also want the AI to make outbound calls, like reminders or follow-ups, those come with their own consent rules under the TCPA. Answering incoming calls avoids those.
Common mistakes with an AI receptionist
- Giving it every call on day one. Start with overflow and after-hours, where every answered call is a call you'd have missed.
- A weak handoff. If the person picking up a transfer doesn't know who's calling and why, callers repeat themselves and get frustrated. Pass the summary with the call.
- Outdated answers. When your prices or hours change, update what the AI knows the same day.
- Never listening to calls. A few minutes a week reviewing calls catches problems before customers do.
- Paying for the premium voice by default. Try the lean setup with real callers first.
Conclusion
An AI receptionist answers every call, books appointments, handles the questions you get all day, and passes the rest to you with a summary. It costs about $0.11 to $0.25 a minute to run, which for most small businesses is a few hundred dollars a month at most. The real return is in the calls you're missing today, so count those first.

Frequently asked questions
It answers every call, handles common questions, books and reschedules appointments in your calendar, takes messages, and transfers urgent or complex calls to a person. It works nights, weekends, and lunch breaks, when most missed calls happen.
Running costs are about $0.11 to $0.25 a minute, depending on the voice and AI model. At 300 three-minute calls a month, that's about $99 to $225, plus the setup and upkeep of the system.
Per call, by a wide margin. A full-time receptionist at the US median wage costs about $4,500 a month with benefits and covers 40 hours a week. An AI receptionist answers around the clock for a few hundred dollars a month in call costs.
Yes. Your number stays the same and calls forward to the AI receptionist, either all the time or only when nobody picks up and after hours.
They should. Have it say it's an AI assistant at the start of the call, and let callers ask for a person at any time. Callers care far more about getting their question answered or their appointment booked.
