An AI receptionist for a small business: what phone agents cost and where callers hang up

The phone rings while you are cutting someone's hair, under a sink, or with a patient. You let it go to voicemail, and the caller rings the next salon, plumber or clinic on the list. For a small business that lives on bookings, that unanswered call is the most expensive thing that happens all day, and it happens many times a week.

AI receptionists promise to fix it: a voice agent that answers every call, day and night, gives your hours and prices, books the appointment and sends you a summary. Some do this well. Some callers hang up the moment they hear one. This piece is for the owner deciding whether to try one: what they cost in 2026, what they handle well and badly, the consent rules for recording and disclosing, and a two-week trial you can run without betting the front desk on it.

What they cost

There are three ways vendors charge, and the right one depends on how many calls you get and how long they last.

- By minutes. Rosie lists $49 a month for 250 minutes, $149 for 1,000 and $299 for 2,000. Its cheapest plan sends a booking link by text; booking straight into your calendar and transferring calls to you start on the $149 plan. Recordings, transcripts, and English and Spanish are on every plan. Overage rates are not on the pricing page, so ask.
- By caller. Goodcall counts unique callers per month, not minutes or calls: $79 for 100 callers (about 150 calls), $129 for 500, $299 for 2,000, with each extra caller at 79, 26 or 15 cents depending on the plan. Spam and wrong numbers don't count.
- By call. Smith.ai's AI receptionist has a free tier with 25 calls, then a Pro plan from $150 for 75 calls (about $2 a call, $2.50 for each extra), with a live receptionist in North America to take over calls the AI can't handle. Its human-first service, for comparison, starts at $300 for 30 calls with $11.50 for each extra.
- Build your own. Developer platforms such as Retell price by the minute in parts: platform, voice, language model and phone line. Retell quotes $0.07 to $0.31 a minute all-in, with $0.11 in its own example. Cheap per minute, but someone has to build, test and maintain the agent, and that someone is usually not the owner of a salon.

A worked example: a salon with 400 calls a month averaging two and a half minutes, about 1,000 minutes, from roughly 280 different callers.

The software is cheap next to a person, and the plan that fits depends on your call pattern: many short calls favour per-caller or per-minute pricing; few long calls favour per-call. The real question is not the bill. It is how many of those 400 callers get what they called for, which is what the trial below measures. If you want to run the sums for a bot that sometimes passes calls to a person, our support bot cost calculator does the same arithmetic for chat and email, and the logic carries over.

What they handle well

Most calls to a small business are the same six questions. Voice agents in 2026 are good at all of them:

- Opening hours, address, parking, whether you are open on a holiday.
- What a service costs and how long it takes, when the answer is on a list you gave it.
- Booking, moving or cancelling an appointment in a calendar it can see.
- Taking a message with a name, number and reason, and sending it to you as a text or email straight away.
- Answering at 9 pm and on Sunday, which is when many people finally get round to calling.
- Filtering spam and sales calls, which can be a surprising share of the total.

Each call becomes a recording, a transcript and a short summary. Even owners who stop using the agent often say that reading a week of summaries was the first time they knew what people actually call about.

Where callers hang up

The hard part is the people who don't want to talk to it. In a 2025 survey of 6,000 adults that OnePoll ran for AnswerConnect, 29% said they hang up as soon as they realise they are connected to AI, and 83% said they want a human when they call a business, rising to almost 90% for legal, medical and trades. AnswerConnect sells human answering, so read its numbers with that in mind, but the direction matches what owners report. The calls that go wrong fall into a few groups:

- The first five seconds. A long greeting, a menu, or a voice that sounds like a sales line. Callers decide fast. A short greeting that says who you are and what the caller can do ("I can book you in or take a message for Maria") keeps more of them.
- Accents, noise and names. Agents mishear street names, surnames and numbers, especially from a car or a building site. Every mistake makes the caller repeat themselves, and the second repeat is usually the last.
- Anything that isn't on the list. "Can you fit my mum in after her chemo on Thursday?" or "the tap is leaking into the flat downstairs" needs judgement. An agent that guesses is worse than one that says it will get you to call back within the hour, and then you do.
- Angry callers. A complaint, a bill dispute or a bad result needs a person. An agent that stays cheerful through it makes things worse.
- Emergencies. A clinic, a vet, a locksmith or a heating engineer gets calls that cannot wait. The agent needs one rule it never breaks: if the caller describes an emergency, tell them to call the emergency number where that applies, and put the call through to a person or the on-call phone at once.
- No way out. The single biggest cause of angry hang-ups is a caller asking for a person and not getting one. Give the agent a transfer number, or at least a promise of a callback with a time.

The agent does not have to answer everything. It has to know what it can't answer, and hand it to a person fast.

Recording, consent and saying it is an AI

Most AI receptionists record and transcribe every call by default. That brings three sets of rules, and the vendor's defaults do not always cover your state or country.

- Recording consent. In the US, most states allow recording when one party to the call consents. About eleven, including California, Florida, Illinois, Maryland, Massachusetts, Montana, Nevada, New Hampshire, Pennsylvania and Washington, require everyone on the call to agree, and when a call crosses state lines the stricter rule is the safe one to follow. The simple fix covers every case: the greeting says the call is recorded. In the UK and the EU, recording is personal data under data protection law, so tell callers, say why, keep the recordings only as long as you need them and check where the vendor stores them.
- Saying it is an AI. Tell callers they are talking to an automated assistant, in the greeting. Under the EU AI Act, systems that talk with people have to make clear they are AI, with those transparency rules applying from August 2026 (our piece on what the AI Act means for a small vendor has the details). Several US states have their own disclosure rules for bots. Honesty also does better: a caller who finds out halfway is the angriest kind.
- Calling people back. Answering incoming calls is one thing. If the agent also rings or texts people (reminders, missed-call callbacks, offers), US rules for automated calls apply: in February 2024 the FCC ruled that AI-generated voices count as "artificial" voices under the Telephone Consumer Protection Act, which needs the person's prior consent. Keep outbound calls to people who asked for them.
- Health information. A clinic in the US that lets the agent hear about symptoms or appointments for treatment is sharing protected health information. Use only a vendor that will sign a business associate agreement, and check it covers the recordings and transcripts.

Write these choices down. If you already have a short AI policy for your staff, the phone agent belongs on it.

A two-week trial

You don't have to hand over the whole front desk on day one. Run it on the calls you are missing now, measure, and widen only if the numbers hold.

Before you start (an afternoon). Write the agent's sheet: hours, address, services and prices, booking rules (how long each service takes, who does what, buffers), the questions it must never answer (medical advice, quotes for jobs it hasn't seen), the emergency rule, and the number it transfers to. Record a greeting that says your business name, that it is an automated assistant and that the call is recorded. Then call it yourself ten times, and ask a friend with a strong accent and one who is good at being difficult to do the same.

Week 1: after hours and missed calls only. Forward calls to the agent only when nobody picks up within four or five rings and outside opening hours. Read every summary and listen to a sample of recordings each evening. Fix the sheet the next morning.

Week 2: busy hours too. If week 1 went well, add the hours when you know you can't pick up: a full chair, a job on site, the school run. Keep listening every day.

Count five things over the two weeks, from the call log and the vendor's dashboard:

1. Calls answered that would have gone to voicemail.
2. Bookings made by the agent that turned up.
3. Hang-ups in the first 15 seconds, against your old voicemail rate. If more people hang up on the agent than on your voicemail, fix the greeting first.
4. Transfers and callbacks you had to make, and how fast you made them.
5. Wrong answers: any booking in the wrong slot, any price or fact it made up. One of these per fifty calls is a lot; each one gets a line in the sheet.

At the end, the decision is usually clear. If the agent books more appointments than it costs and wrong answers are rare, keep it on missed and after-hours calls, and think hard before putting it in front of every caller. If people hang up on it more than on your voicemail, a human answering service for overflow, or simply a clear voicemail with a text-back, may serve you better.
