What an AI receptionist can and can't do for a small business

Picture a plumber under a sink at two in the afternoon, hands wet. The phone rings in the van and rings out. The caller needed a hot water system replaced, and rings the next plumber on the list. Nobody did anything wrong. The call came at the wrong moment.

An AI receptionist is sold as the answer to that moment. It is software that picks up your phone or your website chat when you can't, talks to the person in plain language, and passes on what they wanted. Some of what is promised about it is true. Some depends on how it is set up. Some jobs it should never be given.

We build these, so read this knowing that. It is the page we would want to read before buying one. How we set one up is under AI agents on our Services page.

What it does well

It answers straight away, at two in the afternoon or two in the morning. It handles the questions you answer ten times a day: your hours, where to park, whether you do a certain job, which suburbs you cover. And it takes a proper message: a name, a number, what the person needs and when to call back, sent to you as a text or an email.

Many can speak multiple languages. They are not equally good in all of them. An August 2026 study found every AI agent it tested did worse outside English, and we wrote about how to check yours.

Where it should hand back to you

The mark of a good one is that it knows what it was not told. Three kinds of call test that.

• Anything you never gave it. A price you didn't supply, a service you don't list. The right answer is "I don't have that. Can I take your number so someone can call you back?" The wrong answer is a confident guess. Ask to hear which one you get.
• Advice only you can give. A clinic's receptionist does not tell a caller what their symptom means, and a broker's does not say which loan suits them or whether they will be approved. Software shouldn't either. It can take the reason for the call and book the appointment. The advice is yours.
• Emergencies and upset people. A kitchen filling with water, a patient in severe pain, a complaint. It needs a plain script for these: for danger to life, hang up and ring the emergency number (000 in Australia). For anything urgent, how to reach a person now, if you offer that.

Say that it is an AI

Australia's National AI Centre publishes guidance for businesses adopting AI. Under "Share essential information" it says: "People should know when they’re interacting with AI and understand when AI decisions affect them. For example, when a customer is receiving services and information from a chatbot, they should know this is not a human specialist" (Guidance for AI adoption: foundations).

It is also good sense. A caller who works out halfway through that they have been talking to software trusts the business less afterwards. One sentence at the start is enough: "You've reached Smith Plumbing. I'm an AI assistant, and I can take a message or answer a few questions."

A call collects personal information

A name, a number and a reason for calling are personal information. An AI receptionist usually keeps a written record of the call so it can pass the message on, which is more of it.

Whether privacy law applies depends on the business. The privacy regulator, the Office of the Australian Information Commissioner (OAIC), says "Most small businesses are not covered by the Privacy Act 1988, but some are", and a small business is one "with an annual turnover of $3 million or less". Then it lists who is covered whatever their size, starting with "a health service provider" (OAIC, Small business). So a one-dentist clinic is covered. A plumber under the threshold usually is not. If you are unsure, that page links to a checklist.

If you are covered, callers should be told what is being collected. The OAIC's guidelines give this as a reasonable step: "if personal information is collected by telephone, explaining the APP 5 matters to the individual at the commencement of the call (perhaps following a template script or using an automated message)" (APP guidelines, chapter 5). In practice the greeting says the call is being noted down and where your privacy policy is.

Ask your provider whether calls are recorded, where recordings and written records are kept, and for how long. If the software also decides things, such as who gets the urgent appointment, your privacy policy may need a new section from 10 December 2026.

Three things that are a bigger job

Demonstrations often show more than answering. These are separate pieces of work, so ask which are included.

• Putting a caller through to a person. It has to work with your phone system, and someone has to be there to pick up.
• Booking, quoting or taking an order itself. It needs a connection to your calendar or booking software, and testing. Once software can change things, limit what it is allowed to do.
• Ringing customers. Calls that go out have their own rules, which we covered in automated texts, emails and calls.

Do you need one?

Maybe not. Count first. For two weeks, compare the calls you answered with your phone's missed-call list. If you miss two a week and ring them back within the hour, a clear voicemail greeting and that habit may be all you need.

If you miss ten a day because you are on the tools or with a patient, and most of those callers leave no message, that is the problem this solves.

What to do this month

1. Count your missed calls for two weeks before you talk to anyone selling an answer.
2. Write one page of facts: hours including public holidays, what you do and don't do, the areas you cover, the prices you are happy to state, and how bookings work. Whatever answers your phone should use that page, as we said in our post on Google's automated calls.
3. List the questions it must never answer, and what it says instead.
4. Ask any provider for a test line. Ring it with five real questions, including one it should refuse and one in a language your customers speak.
5. Check the greeting says it is an AI and that the call is being noted.
6. Ask what is extra: putting calls through, booking into your calendar, taking payment, ringing customers.
7. Ask for the cost in three parts, setup, the monthly fee and charges that depend on use such as phone minutes, and ask how you stop.
