Best AI Receptionist and Answering Service for Small Business

What does an AI receptionist actually do?

An AI receptionist answers your business phone with a synthetic voice, talks to the caller in plain language, and does a small set of jobs you define. On typical published plans those jobs are:

• Answer every call, including nights, weekends and the moments when everyone is busy, so callers don't hit voicemail.
• Answer routine questions such as hours, location, services and what to bring, from information you give it.
• Capture details: name, number, reason for calling, and a few intake questions you choose.
• Book appointments into a connected calendar, and text the caller a confirmation or a link.
• Transfer or escalate calls that need a person, ideally with a short summary so nobody has to ask the caller to repeat themselves.
• Send you a summary by text or email, with a recording and transcript.

What it doesn't do well yet is judgment. It can't tell whether a legal matter is worth taking, whether a leaking pipe is an emergency for this customer, or whether a patient's symptom needs a clinician today, unless you've written those rules down for it. That's the part most firms skip.

An AI answering service usually means the same thing. Some providers use "answering service" for staffed services that now add AI, so check whether a person or a machine answers your calls.

The three types of AI receptionist, and who each suits

Almost every product on the market falls into one of three groups. Comparing within a group is useful. Comparing across groups on headline price is misleading.

A common setup for small firms is a hybrid: people during business hours, AI after hours and for overflow. You don't have to choose one for every call.

How much does an AI receptionist cost?

These are ranges from typical published plans we checked on Oct 13, 2026. Prices change often, so treat them as a starting point, not a quote.

Pricing models

• Per call. A monthly bundle of calls, with a fee for each call over it. Common with AI-only services and staffed services alike.
• Per minute. A bundle of voice minutes, then a per-minute charge. Long calls cost more.
• Per unique caller. Some services count each different caller once a month, however many times they call.
• Per seat or add-on licence. Phone-system add-ons are often priced per licence or line, usually through a sales conversation rather than a public price list.

Annual billing typically takes 10 to 20% off. To compare your existing seats and AI tools in one place, use our AI cost calculator.

Hidden costs to check before you sign

• Spam and robocalls. Some plans don't count spam or very short calls; others do. If your number gets a lot of junk, this decides your real bill.
• Overage. A busy month can cost far more than the headline price. Look at your last three months of call logs, not an average.
• Per-feature add-ons. Staffed services often charge extra per call for booking, conflict checks, Spanish-language answering, payments or extra intake questions. These can double the effective cost of a call.
• Integrations. Connecting to your CRM or practice software may be included, cost extra, or need a third-party connector you pay for separately.
• Setup time. The fee is often zero, but someone still has to write the script, the escalation rules and the FAQs, then test them. That's the real setup cost.
• Extra numbers or locations. Additional agents, lines or transfer destinations are often a monthly add-on.

Cheapest and free options

The cheapest AI-only plans start around $20 a month, and some services let you build and test a demo agent free before you connect a number. Free trials of a week or two are common. The tradeoff is the allowance: entry plans cover a few dozen calls, so a real month of traffic often lands you on a higher tier or paying overage. A free trial is the right way to test; a free plan is rarely the right way to run your front desk.

Is an AI receptionist worth it?

It depends on two numbers you can find in an afternoon: how many calls you currently miss, and what one new client or job is worth to you.

If you miss five calls a week from new prospects and one in five would have become work worth $1,000, those missed calls cost you about $1,000 a week. A plan at a few hundred dollars a month is an easy decision. If your phone is quiet and someone always picks up during opening hours, the case is much weaker.

AI receptionist vs human receptionist

• An AI receptionist answers at 2 a.m., handles several calls at once and costs a fraction of a salary. It follows the rules you give it, and it is poor at anything you didn't anticipate.
• A human receptionist reads tone, calms an upset caller, handles the strange call, and does a dozen other office jobs between calls. They also take lunch, holidays and sick days, and they can only answer one line.
• A staffed answering service sits between the two: real people, no salary, but billed per call, and less familiar with your firm than your own staff.

For most small firms the honest answer isn't a replacement. It's coverage: AI for after hours, overflow and routine bookings, and people for the calls that matter most.

AI intake for law firms

For a law firm the phone isn't just a receptionist job; it's intake. The questions are what decide whether an AI receptionist helps or creates risk.

• Intake scripts. Write down, per practice area, the questions that decide whether a matter fits: matter type, jurisdiction, key dates or deadlines, the other party, and how urgent it is. The AI should ask these the same way every time.
• Conflict checks. Capture the names of the opposing parties at first contact, but don't let the AI tell a caller you can act for them. Many staffed services offer a conflict check as a paid extra. Either way, a person should clear conflicts before anyone gives advice or books a consultation as a client.
• No legal advice. The script must stop the AI from answering "do I have a case?" and route that to a person.
• Handoff to your case-management software. The intake summary should land as a new lead or matter record, not just in someone's email. Several services connect to common legal practice-management systems directly or through a connector.
• Existing clients vs new leads. Decide how each is handled. An existing client calling about a hearing tomorrow needs a different path from a new enquiry.

AI receptionists for dental and medical offices

• Practice software. The value is in booking, rescheduling and filling cancellations directly in your practice-management or scheduling system. A receptionist that only takes messages means staff re-key everything the next morning.
• HIPAA. Calls carry patient information, so the provider must sign a Business Associate Agreement (BAA), and you need to know where recordings and transcripts are stored and for how long. Some services offer HIPAA-compliant plans or BAAs only on higher tiers, so ask before you compare prices.
• Clinical triage. Don't let the AI decide whether a symptom is urgent. Give it a short, clinician-approved list of words that trigger an immediate transfer or an emergency instruction.
• New patient intake. Texting a link to your existing intake forms after the call is often more useful than asking every question by voice.

AI receptionists for contractors, plumbers and HVAC

For trades the money is in after-hours calls. A burst pipe at 9 p.m. goes to whoever answers first.

• Emergency triage. Define what counts as an emergency for you, such as no heat in winter, active leaks or no power, and what the AI does about it: page the on-call tech, quote the call-out fee, or book first thing tomorrow.
• Capture the job properly. Address, the problem in the customer's words, photos by text, and whether they own the property.
• Book into the job system you already use. If you schedule in field-service software, the receptionist should create the job there, not send an email someone forgets.
• Quote rules. Decide whether it can give ballpark prices or call-out fees. Unclear pricing is the fastest way to annoy a caller.

Map your calls before you buy

Every AI receptionist works from instructions. If yours are vague, it will be vague on the phone. Before you compare products, write down four things:

1. Who calls. New prospects, existing clients, suppliers, spam, and what share of each. Your phone system's call log usually shows this.
2. What you need to capture. The minimum details per caller type, in order. Usually five or six questions, not twenty.
3. When to escalate. The specific situations that go to a person immediately, who that person is, and what happens if they don't pick up.
4. Where the notes land. The exact place each call should end up: your CRM, your case-management system, your practice software, your job board, or a shared inbox. If the answer is "someone's email," fix that first.

This is the work we do. We're not a receptionist vendor and we don't sell one. We map your calls, help you pick the type and tier that fits, connect it to the tools you already use, and test it on real calls before it goes live. Sometimes the answer is a cheaper fix: a better voicemail, a callback rule, or a booking link.
