AI Receptionist for Small Business: What It Does, What It Costs, Do You Need One?
Every small business owner knows the feeling: you are with a client, under a sink, or in court, and the phone rings. You can’t answer it, and the caller probably won’t wait.
An AI receptionist for small business is software that answers your phone with a natural-sounding AI voice, 24 hours a day. It can answer common questions, book appointments into your calendar, take messages and pass urgent calls to you. Plans from well-known providers start at about $29 a month for light use and run to $300 to $500 a month for busier lines (prices checked November 2026). You need one if you regularly miss calls that could be paying work. You probably don’t if calls are rare or every call needs a real conversation with you.
At a glance
- What it does: answers calls, answers FAQs, books appointments, takes messages, transfers urgent calls
- Typical cost: about $29 to $500 a month, depending on call volume
- Setup time: an afternoon for a basic setup, longer if you connect a CRM
- Best for: clinics, law firms, home services, agents and agencies that miss calls
- Not great for: emotional, complex or high-stakes conversations
What does an AI receptionist actually do?
An AI receptionist picks up the call, understands what the caller says, and responds out loud using information you give it: your hours, services, prices, service area and booking rules. When the call ends, it sends you a summary or transcript by email or text.
Most tools cover the same core jobs:
- Answer common questions such as opening hours, location, prices and whether you cover a postcode.
- Book appointments straight into a connected calendar.
- Qualify leads by asking a few set questions (what they need, when, budget, location).
- Take messages and send you a written summary.
- Transfer calls to you or a colleague when something is urgent.
Here is how that plays out in a few different businesses:
| Business | Typical call | What the AI does |
|---|---|---|
| Dental clinic | “Can I book a cleaning next week?” | Checks the calendar, offers two slots, books one, texts a confirmation |
| Law firm | “I need advice about a contract dispute” | Takes name, matter type and urgency, sends the intake summary to the right lawyer |
| Plumber or electrician | “My boiler has stopped working” | Asks the address and problem, flags it as urgent, transfers or texts the on-call engineer |
| Estate agent | “Is the flat on High Street still available?” | Captures the enquiry, asks buying or renting and timeline, books a viewing callback |
| Small agency | “Do you build websites for restaurants?” | Answers the basics, asks budget and deadline, books a discovery call |
How much does an AI receptionist cost?
Most AI receptionists charge a monthly fee that includes a set number of minutes or calls, then charge for extra use. For a small business, expect roughly $29 to $150 a month for low volume and $200 to $500 a month for a busy line. Two real examples, checked November 2026:
| Provider and plan | Monthly price | Included | Extra use |
|---|---|---|---|
| Dialzara Business Lite | $29 | 60 minutes | $0.48 per minute |
| Dialzara Business Pro | $99 | 220 minutes | $0.45 per minute |
| Dialzara Business Plus | $199 | 500 minutes | $0.40 per minute |
| Smith.ai AI Pro, Tier 1 | $150 | 75 calls | $2.00 per call |
| Smith.ai AI Pro, Tier 2 | $270 | 150 calls | $1.80 per call |
| Smith.ai human receptionist, Starter | $300 | 30 calls | $11.50 per call |
Dialzara prices come from Dialzara’s own pricing page (updated October 2026). Smith.ai figures are from Quo’s Smith.ai pricing breakdown (July 2026); other sites quote different Smith.ai numbers, so check the provider’s page before you sign up.
For comparison, the median receptionist in the US earned $38,010 a year ($18.27 an hour) in May 2025, according to the US Bureau of Labor Statistics. That is before taxes, holidays and sick days, and a person covers one shift, not nights and weekends.
Watch out: per-minute and per-call pricing behave very differently. Lots of short calls favour per-minute plans; fewer, longer calls favour per-call plans. Look at last month’s call log before picking a plan.
Do you need an AI receptionist? A simple test
You likely need one if missed calls are costing you work. Callers don’t wait around: in Moneypenny’s Small Business Call Report, 69% of callers who reached voicemail hung up without leaving a message. Older data, but it matches what most owners see.
| Your situation | Do you need one? | Why |
|---|---|---|
| You miss calls most days while working | Yes | Every missed call is a lead that may ring a competitor next |
| Lots of calls after hours or at weekends | Yes | The AI covers the hours nobody is at the desk |
| Most calls ask the same five questions | Yes | The AI answers them in seconds and frees your time |
| A handful of calls a week | Probably not | A missed call text back or voicemail is cheaper |
| Every call is sensitive or complex | Probably not | Callers need a person; use a human answering service |
Our pick: start cheap. A $29 to $99 plan answering after-hours and overflow calls tells you within a month whether the extra leads justify a bigger plan. If you only miss a few calls, try a missed call text back first.
How to set up an AI receptionist the simple way
Setup is mostly writing down what a good receptionist would already know. Keep it short and clear.
- Pick a plan sized to your current call volume
- Add your hours, services, prices and service area
- Write the 5 to 10 questions callers ask most
- Connect your calendar and set booking rules
- Decide what counts as urgent and who gets transferred
- Forward missed or after-hours calls to the AI number
- Call it yourself and fix anything it gets wrong
The greeting matters more than most people think. Be upfront that it is an assistant. Callers tend to work it out anyway, and honesty builds trust.
Greeting · General small business
Thanks for calling [business name]. I’m [business name]’s virtual assistant. I can answer questions, book an appointment or take a message for the team. How can I help today?
Greeting · Clinic
Thanks for calling [clinic name]. I’m the clinic’s virtual assistant. I can book, move or cancel an appointment, or take a message for the team. If this is a medical emergency, please hang up and call [local emergency number].
Instructions · Lead qualifying questions
For every new enquiry, ask: 1) What do you need help with? 2) Where are you based? 3) When do you need it done? 4) What is the best number and email to reach you? Then offer the next available appointment or say a team member will call back within [time].
Instructions · When to transfer
Transfer the call to [name] at once if the caller mentions [urgent words, e.g. leak, no heating, court date tomorrow] or asks to speak to a person twice. Otherwise take a message and send a summary to [email or phone].
Shortcut: the AI only answers well if its replies are fast on every channel. Pair it with an instant WhatsApp auto reply so web and chat enquiries get the same treatment.
What most guides leave out
Most AI receptionist articles are written by companies selling one, so a few things get skipped.
- Answering the call is only half the job. If the AI takes a message and nobody calls back for two days, you lost the lead anyway. Decide who follows up and how fast. Our guide to speed to lead explains why the first reply wins.
- The cheap plan is rarely the real price. Overage fees, transfers and integrations often sit on higher tiers. On Dialzara, for example, warm call transfer is listed on the Elite plan ($349 a month), not the $29 plan.
- It needs a weekly check at first. Read the call summaries for the first few weeks. You will spot questions it fumbles and can add better answers.
- Some calls should never go to AI. Complaints, bereavements, legal emergencies and angry customers need a human. Set a clear transfer rule for them.
- Check the rules where you operate. Recording and AI disclosure rules vary by country and state. Tell callers they are speaking to an assistant and, if calls are recorded, say so.
Frequently asked questions
Will callers know they are talking to AI?
Often, yes. Modern voices sound natural, but most callers work it out within a few sentences. That’s fine if the assistant is useful and you say upfront that it is a virtual assistant.
Can an AI receptionist book appointments?
Yes. Most connect to Google Calendar, Outlook or booking tools, check free slots and book the caller in. Set rules for buffer time and services so it doesn’t double-book or book the wrong length.
Is an AI receptionist cheaper than a human?
Usually, by a lot. Plans run from about $29 to $500 a month, while a US receptionist’s median pay was $38,010 a year in May 2025. A human is still better for sensitive or complex calls.
Can I keep my existing business number?
In most cases, yes. You set your phone to forward unanswered, busy or after-hours calls to the AI’s number, so customers keep calling the number they already know.
What is the difference between an AI receptionist and an answering service?
An answering service uses real people, usually charging per call or per minute at a higher rate. An AI receptionist is software that handles routine calls cheaply around the clock. Some providers offer both, with people stepping in when the AI can’t help.
