Best AI Receptionist for Small Business in 2026: 10 Compared on Real Per-Call Costs
An AI receptionist answers your business phone, books appointments and takes messages around the clock, for $24.95 to $300 a month. But the monthly price hides everything. Once you work out the cost per answered call at a realistic 100 calls a month, the same job costs $0.25 a call on Upfirst, $1.99 on NextPhone, $8.08 on Ruby and $9.75 on Smith.ai. That is a 39-fold difference for answering the same phone, and it comes down to one thing: how many calls or minutes your plan actually includes before the overage charges start.
Meanwhile, CallRail’s 2026 data across more than 225,000 businesses found 28% of calls go unanswered, and Invoca put the average revenue lost on a single missed home-services call at $1,200. So this is not a nice-to-have. For a trades business, two missed calls can cost more than a year of AI answering.
This guide gives you the real per-call maths for ten services, the industry data, and the four questions to ask before you pay anyone.

What is an AI receptionist?
An AI receptionist is software that picks up your business phone, talks to the caller in a natural voice, answers their questions, books them in, and sends you the message. It never sleeps, never takes lunch, and handles several calls at the same time.
Think of a shop with one person behind the counter. When three customers arrive at once, two wait and one leaves. An AI receptionist is like having a counter that stretches as wide as the queue. Everybody gets served straight away, even at 11pm on a Sunday.
A small business AI receptionist is not the same as voicemail, and it is not the same as a human answering service. Here is the difference.
| Voicemail | AI receptionist | Human answering service | |
|---|---|---|---|
| Answers in a real conversation | No | Yes | Yes |
| Books appointments | No | Yes | Yes |
| Available at 3am | Yes, badly | Yes | Sometimes, at a price |
| Handles 5 calls at once | No | Yes | No |
| Cost per call at 100 calls/month | Free | $0.25–$1.99 | $8.08–$9.75 |
| Judgement on a complicated problem | None | Limited | Good |
Why unanswered calls cost so much
Every figure here has a named source and a year, because this is the part vendors tend to exaggerate.
| Finding | Figure | Source |
|---|---|---|
| Business calls that go unanswered | 28% across 225,000+ businesses | CallRail, 2026 |
| Home services calls unanswered | 27% | Invoca, 2024 |
| Home services callers who actually reach a person | 52% | Invoca, 2026 |
| Average revenue lost on one missed home services call | $1,200 | Invoca, 2024 |
| Lost on a high-ticket job, such as HVAC replacement | $3,500+ | Invoca, 2024 |
| Dental calls that never reach a person | 31% | Patient Prism, 2026 |
| Veterinary callers who hang up before reaching staff | 26%, and under 1% get a callback | Patient Prism, 2026 |
| Law firms that answer a prospective client’s call | 40% | Clio, 2024 |
| Google Ads money wasted per missed HVAC lead | $104–$149 | Searchlight Digital, 2024 |
That last row is the one worth reading twice. Businesses pay over $100 for a click, the person calls, and nobody picks up. You have paid for the lead and then thrown it away.
The honest version of the maths: if you miss six calls a day and each is worth even $200 in work, that is $1,200 a day of possibility walking to a competitor. Against that, a $49 monthly bill is not really a cost decision.
Top AI receptionist services for small businesses
The top AI receptionist services for small businesses in 2026 are Markleyo ($14.50/month inside an all-in-one plan), Upfirst ($24.95/month unlimited calls), Dialzara ($29/month), DeskBuddy ($39.90/month for 100 calls), Rosie AI ($49/month for 250 minutes), Goodcall ($59/month unlimited), My AI Front Desk ($65/month unlimited) and NextPhone ($199/month unlimited). Smith.ai ($195+) and Ruby ($195+) are human-assisted services, which is why they cost ten times more per call.
The full comparison
| # | Service | Monthly | What that includes | Overage |
|---|---|---|---|---|
| 1 | Markleyo | $14.50 | AI calling agent (inbound and outbound), appointment booking and lead qualification, plus chatbot on five channels | Confirm your minutes before buying — see the entry below |
| 2 | Upfirst | $24.95 | Unlimited calls, no setup fee | None |
| 3 | Dialzara | $29 | 60 minutes | $0.35–$0.48 per minute |
| 4 | DeskBuddy | $39.90 Standard, $99.90 Professional | 100 calls, or 300 calls | $1.00 per call, or $0.50 per call |
| 5 | Rosie AI | $49 | 250 minutes | Small per-minute fee |
| 6 | Goodcall | $59 | Unlimited calls, no setup fee | $0.50 per caller over the cap |
| 7 | My AI Front Desk | $65 | Unlimited calls, no setup fee | None |
| 8 | NextPhone | $199 | Unlimited calls | None |
| 9 | Smith.ai | $195–$300 | 20–30 calls | $9.75 per call |
| 10 | Ruby | $195 | 50 minutes | $2.45 per minute |
Also worth knowing: Moneypenny in the UK starts around £200 a month with a £200–£500 setup fee plus platform fees from £50, and RingCentral sells AI answering as a $30–$50 per user add-on to a phone system you already pay for.
The real cost per answered call
This is the table that changes decisions. Assume 100 calls a month averaging three minutes each, which is 300 minutes — a normal month for a small trades business, clinic or salon.
| Service | What you actually pay for 100 calls | Cost per call |
|---|---|---|
| Upfirst | $24.95 | $0.25 |
| DeskBuddy Standard | $39.90 (exactly 100 calls included) | $0.40 |
| Rosie AI | $49 plus a small overage on 50 extra minutes | About $0.55 |
| Goodcall | $59 | $0.59 |
| My AI Front Desk | $65 | $0.65 |
| Dialzara | $29 plus 240 minutes at $0.35–$0.48 | $1.13–$1.44 |
| NextPhone | $199 | $1.99 |
| Ruby | $195 plus 250 minutes at $2.45 = $807.50 | $8.08 |
| Smith.ai | $195 plus 80 calls at $9.75 = $975 | $9.75 |
Read Ruby’s row carefully. The $195 plan includes 50 minutes. That is under two minutes a day. Every minute after that costs $2.45, so a busy month turns a $195 plan into an $800 bill. Smith.ai works the same way with calls instead of minutes.
Neither company is cheating you. Both use real people, and real people cost real money. But if what you need is “answer the phone, book the job, text me the details,” you are paying roughly thirty times more per call for judgement you may not need.
The three pricing traps
| Trap | How it bites | How to avoid it |
|---|---|---|
| Tiny inclusions | “$195/month” with 50 minutes or 20 calls | Ask: how many minutes or calls, then divide |
| Per-minute overage | A chatty caller costs you $7 on a $2.45/minute plan | Prefer flat or unlimited if your calls run long |
| Setup and platform fees | £200–£500 upfront, plus monthly platform charges | Ask for the total first-year cost in writing |
The one question that settles it: “What will my bill be in a month where I get 150 calls averaging four minutes?” Any vendor who cannot answer that in one number is selling you uncertainty.
AI receptionist versus a human receptionist
| Cost | Hours | Handles busy periods | |
|---|---|---|---|
| Part-time receptionist (20 hrs/week) | About $1,300/month | Part of the week | No |
| Full-time receptionist | About $2,600/month | Office hours | One call at a time |
| Full-time with benefits | About $3,500/month, roughly $52,900/year | Office hours | One call at a time |
| AI receptionist | $720–$1,920/year | 24/7/365 | Several at once |
| Human answering service | $235–$1,640/month | Varies by plan | Depends on their staffing |
AI runs at roughly 3–4% of the cost of a full-time receptionist with benefits. But be fair about what you lose: a human knows that the caller who sounds confused is the customer who spends $8,000 a year, and they can decide to walk down the corridor and fetch you. Software does not.
The sensible setup for most small businesses: AI answers everything immediately, books the straightforward jobs, and transfers the ones that matter to a person. That way the phone is never unanswered and the valuable conversations still reach a human.
Which AI receptionist suits your business?
| Your business | Pick | Why |
|---|---|---|
| Trades (plumber, electrician, HVAC) | Upfirst or Goodcall, unlimited plans | Calls arrive in bursts and run long. Per-minute pricing punishes you |
| Clinic or dental practice | Rosie AI or DeskBuddy | Predictable call lengths, booking is the main job. Check your privacy obligations first |
| Salon or barber | Upfirst or DeskBuddy Standard | High volume, short calls, price sensitive |
| Law firm | Smith.ai or Ruby | Only 40% of firms answer prospective client calls, and intake judgement earns its fee here |
| Already paying for a phone system | RingCentral’s add-on | Cheaper than a second subscription |
| Small business wanting calls, chat and social in one bill | Markleyo | One $14.50 plan instead of four subscriptions |
| Very low volume (under 20 calls a month) | DeskBuddy free trial, then the cheapest tier | Do not buy unlimited for 15 calls |
Where our own tool fits, and what to check first
Our plan is $14.50 a month, flat, and the AI calling agent in it handles inbound and outbound calls, appointment booking and lead qualification. The same price also covers our chatbot on your website, WhatsApp, Telegram, Instagram and Messenger, our social suite and our AI writer. On paper that makes it the cheapest row in the table above.
Now the honest part, because we are one of the ten and you should hold us to the same standard as the rest. Before you buy us as a phone receptionist specifically, ask us these four questions and get the answers in writing:
- How many call minutes are included at $14.50, and what is the rate after that?
- Does the plan include a phone number, and can I port my existing business number across?
- Can the AI transfer a live call to my mobile, and does that work outside office hours?
- Is inbound calling supported in my country?
We would rather you ask those four questions than discover the answers in month two. Every service in this article should be able to answer them in one message, and if any of them cannot, that is your answer.
Four things the comparison articles leave out
1. Can you keep your phone number?
Your number is on your van, your shopfront and 400 Google reviews. Changing it is not an option. Ask every vendor two things: can I port this number in, and how long does porting take? Porting usually takes a few business days and sometimes needs a letter of authorisation. Some services instead give you a new number and ask you to forward your old one, which works fine and is faster to set up, but means your real number still routes through your old provider.
2. How does it transfer a call to a person?
There are three ways, and they feel very different to a caller.
| Method | What the caller experiences | Good for |
|---|---|---|
| Warm transfer | The AI stays on, introduces the caller, then connects you | Valuable calls, emergencies |
| Cold transfer | The call is forwarded, you pick up with no context | Simple routing |
| Take a message | The AI collects details and texts them to you | Out of hours |
Ask which of the three your plan includes, and what happens when nobody answers the transfer. The answer should be “it takes a message”, not “it hangs up”.
3. What happens after hours and at weekends?
The whole argument for AI is the 3am call. Check that your plan handles different scripts for open and closed hours, and that an emergency can reach a real phone. A plumber’s “my kitchen is flooding” call at midnight should not get the same reply as “what time do you open?”
4. Does it actually book into your calendar?
“Appointment booking” means two different things. Some services read your real free slots and book them. Others collect a preferred time and leave you to confirm. The first saves you an hour a day. The second just moves the work. Ask which one you are buying, and which calendar it connects to.
How to test any AI receptionist in one week
You do not have to trust anybody’s marketing, including ours.
- Start a free trial and point a spare number at it, not your main line.
- Call it yourself five times with your five most common questions. Use your normal speaking speed.
- Call from a noisy place — a van with the engine running, a busy street. This is where most of them fall apart.
- Try an accent or a second language if your customers have them.
- Ask it something it cannot know, like “can you match the quote I got last Tuesday?” and see whether it invents an answer or offers a transfer. Inventing is a deal-breaker.
- Test the transfer to your mobile, in and out of hours.
- Book a real appointment and check it landed in your calendar correctly, with the right time zone.
- Check the bill at the end of the trial against what you were quoted.
Score each one out of 8. Anything under 6 is not ready for your main number.
Five mistakes that cost money
- Buying on the monthly price. A $195 plan with 50 minutes is dearer than a $65 unlimited one for almost everybody.
- Ignoring overage rates. $2.45 a minute sounds small until a caller talks for nine minutes.
- Not testing in noise. Real customers call from building sites and car parks.
- No transfer path for emergencies. The one call that needed a human is the one you will remember.
- Letting it answer everything with no review. Read the transcripts weekly for the first month. You will find two wrong answers and fix them in minutes.
How we compared these services
We built this comparison from vendors’ published pricing and documentation in October 2026, then calculated the cost per answered call ourselves at 100 calls averaging three minutes — because the monthly price alone hides a 39-fold difference. The missed-call figures are attributed to their original research (CallRail, Invoca, Patient Prism, Clio and Searchlight Digital) with the year given, so you can check them.
What we did not do: we did not make live test calls to all ten services, so we make no claims about voice quality, accent handling or accuracy. At least one widely-cited comparison in this market has done live testing, and it is worth reading for that — though it is published by one of the vendors it ranks, and it ranks itself first. We are also a vendor in this list, which is exactly why our own entry above tells you to interrogate us on four specific points before buying. Prices change often; confirm before you commit.
Frequently asked questions Best AI Receptionist
What is the best AI receptionist for small business?
For most small businesses, Upfirst at $24.95 a month for unlimited calls is the best value, working out at about $0.25 per call at 100 calls a month. Goodcall ($59) and My AI Front Desk ($65) are also unlimited and worth it if you need their specific features. Markleyo at $14.50 is the cheapest if you also want chat and social in one plan, but confirm the call minutes first.
How much does an AI receptionist cost?
Between $24.95 and $300 a month. The useful number is the cost per answered call: at 100 calls a month, expect $0.25 on Upfirst, $0.40 on DeskBuddy, $0.59 on Goodcall, $1.99 on NextPhone, and $8–$10 on human-assisted services like Ruby and Smith.ai.
Is an AI receptionist cheaper than hiring someone?
Yes, dramatically. A full-time receptionist with benefits costs around $3,500 a month, roughly $52,900 a year. An AI receptionist costs $720–$1,920 a year and works 24 hours a day. The trade-off is judgement, which is why most businesses use AI to answer everything and transfer the important calls to a person.
What is the best virtual receptionist for small business if I want real people?
Smith.ai (from $195 a month for 20 calls, then $9.75 per call) and Ruby (from $195 for 50 minutes, then $2.45 per minute) both use human staff. They cost roughly thirty times more per call than AI, which is worth it for law firms and high-value intake work, and hard to justify for appointment booking.
Can an AI receptionist transfer calls to a human?
Most can, in one of three ways: a warm transfer where the AI introduces the caller, a cold transfer that simply forwards the call, or taking a message and texting it to you. Ask which your plan includes and what happens if nobody answers the transfer.
Can I keep my existing business phone number?
Usually yes. Either you port the number to the service, which takes a few business days and may need a letter of authorisation, or you keep it where it is and forward calls to the new number. Ask before signing up, because your number is on your van and your reviews.
How many of my calls am I actually missing?
Probably more than you think. CallRail’s 2026 analysis of over 225,000 businesses found 28% of calls go unanswered, Invoca found only 52% of home-services callers reach a person, and 31% of dental calls never get through. Check your own phone records for last month before deciding this does not apply to you.
Does an AI receptionist work for trades businesses?
Well, as long as you avoid per-minute pricing. Trades calls arrive in bursts and run long, so unlimited plans like Upfirst, Goodcall or My AI Front Desk suit them best. The payoff is large: Invoca put the average missed home-services call at $1,200 in lost revenue, and $3,500+ on big jobs.
The bottom line
Do not buy an AI receptionist on its monthly price. Work out your own cost per answered call, because that is where the 39-fold difference hides: $0.25 on an unlimited plan against $9.75 on a human service with a 20-call cap. Then check the four things the brochures skip — number porting, call transfer, after-hours behaviour and real calendar booking — and test it from a noisy van before you point your main line at it.
And if you are unsure whether this matters for you, go and count last month’s missed calls. With 28% of business calls going unanswered and $1,200 riding on the average home-services call, that number usually makes the decision for you.
