Best AI receptionist and phone answering services

A missed call is usually a lost job, and most small businesses miss a lot of them. You’re on a job, it’s after six, two calls come in at once. An AI receptionist answers the phone for you, around the clock: it greets the caller, answers the common questions, books the appointment or takes the details, and texts you the summary. It costs a fraction of a person and it never lets the phone ring out.

No single tool wins for everyone, and almost every “best AI receptionist” list you’ll find is published by a company that sells one of them. The right pick turns on two things those ranking posts skip. First, how often your calls genuinely need a human: pure-AI tools answer every call themselves, while a hybrid puts a person on the hard ones. Second, what the call has to do: take a message, answer questions, book into your calendar, or qualify a lead. Get those straight and the choice is quick. Rosie is the cheapest serious way in. Goodcall gives the most predictable bill and suits trades and salons booking jobs. Smith.ai puts real humans behind the AI for the calls that need one. Sona builds the receptionist into your phone system, and NextPhone charges one flat rate for unlimited calls.

The line-up, and what each tool really is

Group these by how the tool answers and how it bills, because those two things, not a star rating, are what change your experience and your invoice.

Tool	What it really is	Price and model (USD)	Best for
Rosie	Pure-AI answering service	$49/mo for 250 mins; booking and transfers from $149	The cheapest serious start; solo owners and trades
Goodcall	Pure-AI agent with booking and call logic	$79/mo, billed per unique caller, unlimited minutes	Salons, trades, multi-location; a predictable bill
Smith.ai	Hybrid: AI front, human agents behind	~$95/mo per-call, plus $3/call for a live human	Calls that need judgement; lead intake; law firms
Sona (by Quo)	AI agent built into a business phone system	Add-on from $25/mo; free tier on every Quo plan	Wanting the receptionist inside your phone system
NextPhone	Flat-rate pure-AI receptionist	$199/mo flat, unlimited inbound calls, no overage	Steady volume where overage anxiety is the issue

All prices are in US dollars and pre-tax, and this category re-prices constantly, so read the table as a snapshot and confirm the current number on each vendor’s page before you commit. The grouping matters more than the order: the first two are the affordable on-ramp for a business that mostly needs calls answered and jobs booked, Smith.ai is the step up when a human needs to be reachable, and the last two are about how you’d rather pay and where the tool lives.

Why the phone is the channel worth fixing first

The phone leaks money faster than any other channel, because a caller who doesn’t get through rarely tries twice. They ring the next business on the list. Lead Response Management research by Dr James Oldroyd, drawn from more than 15,000 leads and 100,000 call attempts, found your odds of reaching someone drop roughly tenfold once you slip past the first five minutes, and that over 30% of leads are never contacted at all. Harvard Business Review made the same point in The Short Life of Online Sales Leads: speed decides the sale, and most businesses are far too slow. A call that rings out at 5pm is that slow response, and it costs you the job.

After-hours is where it’s worst, and where AI pays for itself fastest, because it answers at 9pm and on Sunday for the same flat cost as Tuesday lunchtime. If you’re a trade or a clinic, the caller who can’t reach you has a problem now and will phone whoever picks up. Answering, even just to take the details and promise a callback first thing, keeps the job in your pipeline instead of your competitor’s.

Pure AI or AI plus a human: the split that decides your pick

This is the call that sorts the whole category, so make it first. A pure-AI receptionist answers every call itself. It’s cheap, instant, never sleeps, and genuinely good at the routine majority: hours, prices, booking, directions, taking a message. A hybrid puts AI on the front and routes the calls it shouldn’t handle to a trained human. It costs more per call, and it’s worth it when a real slice of your calls need judgement, reassurance, or a careful hand.

An AI receptionist is just an AI agent whose channel is a phone line, so the same rule applies as everywhere else: it’s brilliant on bounded, repetitive work and shaky on the messy stuff. Our AI agents explainer puts that in plain terms, and the agentic AI guide is candid about how often they get things wrong. The phone version of the question is simply: of your last fifty calls, how many would you have been happy for a sharp junior to handle alone? If it’s most of them, pure AI is plenty. If a real number needed you, buy the human backup. And if the work you want covered is chat and email rather than the phone, that’s a different tool: our customer service software comparison sorts those out.

Rosie: the cheapest serious way in

If you want to stop missing calls this week without a project, start with Rosie. It’s a pure-AI answering service that trains itself on your website and Google Business Profile in minutes, answers in your chosen voice, screens spam, and texts you a summary, transcript and recording of every call. Setup is genuinely a sit-down-once job, not a build.

Read the plans closely, because the cheap one is message-taking, not booking. Professional at $49/mo covers 250 minutes, FAQ answering and message-taking. Appointment booking, warm transfers and live call transfers only arrive on Scale at $149/mo with 1,000 minutes, and Growth at $299/mo adds 2,000 minutes and waterfall transfers that try several of your numbers until someone picks up. Every plan includes call recordings, English and Spanish, and a Zapier connection to push details into your other tools. There’s a 7-day free trial. For a sole trader who mostly needs the phone answered and a text with the details, the $49 plan is the best-value entry on this page. If booking jobs straight into the calendar is the point, you’re really comparing the $149 plan, so price it against Goodcall.

Goodcall: the predictable bill, built for bookings

Goodcall is the pick when you want a fixed, foreseeable cost and proper booking logic, and it’s aimed squarely at trades, salons and multi-location service businesses. The reason to choose it is how it bills: by unique caller, not by the minute. Starter is $79/mo (or $66 on annual) for up to 100 unique callers a month, Growth $129/mo for 250, and Scale $249/mo for 500, with unlimited minutes on every plan and $0.50 per extra caller over the cap. A regular who phones ten times in a month counts once, and a long call never costs you more, so a chatty customer base doesn’t blow up the invoice.

Underneath, it’s the most configurable of the affordable tools. You build “skills” for what the agent says and “logic flows” for what it does: book an appointment, send a text with a pricing link, qualify a caller and route them to the right person. It books into your calendar, connects to your CRM through Zapier, and works with Google Voice. You get a Goodcall number and keep your own by forwarding calls to it. If your business runs on appointments and you want the monthly cost nailed down, this is the one to trial first. Goodcall offers a 14-day free trial.

Smith.ai: AI on the front, humans for the hard calls

Smith.ai is the answer when you can’t hand every call to a bot. Its AI Receptionist answers first, and when a call gets complex, emotional or high-value, it transfers to a North-America-based human agent, live, day or night. That hybrid is the product, and it’s why Smith.ai costs more than the pure-AI tools and is worth it for the businesses that need it. It’s built around lead qualification and intake, with deep hooks into legal tools like Clio, MyCase and Filevine, which is why law firms lean on it.

The pricing reflects the model. The AI Receptionist starts at roughly $95/mo for about 50 calls on per-call billing, with overage in the low-$2-per-call range, and the live human handoff is $3 a call on top. Calls are billed whole, not by the minute, which Smith.ai argues keeps its incentives aligned with yours. There’s a 30-day money-back guarantee for new clients, up to $1,000, which is a fair way to test it on your real calls. The honest read: if nearly all your calls are routine, you’re paying a premium you don’t need, and Rosie or Goodcall will serve you for less. If a steady slice of your calls genuinely need a person, the human backup is the entire reason to be here.

Two more worth knowing: built-in and flat-rate

Sona is the pick if you’d rather the receptionist lived inside your phone system than bolted onto it. Sona is the AI voice agent from Quo (formerly OpenPhone), so it answers, books, takes messages and transfers from within the same app that runs your business calls and texts. Every Quo plan includes about 10 Sona calls free, and paid Sona tiers run $25/mo for 40 calls, $49/mo for 100, $99/mo for 250 and $199/mo for 600, with the per-call overage falling as you go up. The catch is the tie-in: Sona only works inside Quo, on a paid plan, and answers inbound calls only. If you already want a modern business phone, that’s a feature; if you’re happy with your current number setup, it’s a reason to look at the standalone tools instead.

NextPhone is the flat-rate option: $199/mo for unlimited inbound calls, no per-call meter and no overage, which kills the “what will a busy month cost” worry. The flat-rate band, roughly $149 to $299 a month, makes sense once your volume is high enough that per-call pricing would cost more, or when predictability matters more than a low floor. NextPhone claims its AI resolves 90 to 95% of calls without a human, which is the vendor’s own number, so treat it as a ceiling to verify on a trial rather than a promise.

The niche pick: a receptionist built for your industry

The fastest-growing corner of this market is vertical: receptionists built for one industry, that know its workflow and plug into its software, and they often beat the generalists on their home turf. If you’re in one of these, look here first.

For dental practices, Arini is the leader, answering patient calls in well under a second and integrating natively with the systems dentists actually run (Dentrix, Open Dental, Eaglesoft and the rest). For medical and clinics, Lyngo and Simbo AI answer calls, book appointments and verify insurance against your practice software, with the compliance a clinic needs (Assort Health is another in this space). For restaurants, Slang.ai and Loman handle reservations and the endless “are you open” calls, wired into OpenTable and the booking tools. For home services and trades, Avoca is built around dispatch and now books serious job volume for plumbers and HVAC firms. There are equivalents springing up for salons (TrueLark) and vets too.

The reason these win in their niche is the wiring, not the voice. A vertical tool that reads your practice software or your reservation system, knows the difference between an emergency and a routine booking, and escalates the way your industry expects, captures jobs a general tool would fumble. If a tool exists for exactly your trade, trial it against the generalists above before you decide, because the integrations are usually what settles it.

How they’re priced, and why the models don’t compare

The single most confusing thing about shopping for this is that the prices aren’t measuring the same thing. There are four billing models here, and the cheapest one depends entirely on how your phone actually rings.

Rosie bills by the minute (a monthly allowance, then overage). Goodcall bills by unique caller, with minutes unlimited. Smith.ai and Sona bill by the call. NextPhone bills a flat rate. So the right model follows your call pattern. Long calls or repeat callers favour Goodcall’s per-caller model or a flat rate, because neither punishes time on the line. Spiky volume, like a campaign or a seasonal rush, favours flat-rate, where a busy month costs the same. Low, steady volume favours per-call or per-minute, where you only pay for what comes in. Work out your rough monthly calls and average call length first, then read each plan in those units. A $49 plan with a tight minute allowance can cost more than a $79 plan with none, once a few calls run long.

Whatever the model, the comparison that matters is against the alternative. A full-time receptionist is around $4,000 a month by Smith.ai’s reckoning, covers one set of business hours, and takes holidays. Every tool here is between $49 and $299 a month and answers at 3am. Even the dearest hybrid plan is cheaper than the calls it saves once your phone rings with real work, which is the same lean-team logic in doing more with the team you have: you’re not replacing a person, you’re stopping the leak that was costing you jobs.

The things the demos hide

The demo always sounds great. Three things decide whether it sounds great on your actual calls, and none of them show up in a sales video.

The first is latency and talking over the caller. A voice agent that pauses a beat too long, or cuts in before the caller finishes, feels wrong in a way a slow chat widget never does, and people hang up. Phone the tool’s own demo line before you buy and listen for the rhythm, not the script. The second is getting names, numbers and addresses right on a noisy line. For a trade or a clinic, a transcript that records the wrong mobile number or misspells a street is worse than a missed call, because you think you’ve captured the lead and you haven’t. Test it with a few hard ones: an unusual surname, a mobile read out fast, an address with a tricky spelling. The third is the warm transfer. When the agent hands a call to you or a staff member, it should brief you first (“Sarah, calling about a burst pipe in Newstead”) so the caller doesn’t start over. A cold dump to voicemail is the moment you lose the goodwill the AI just earned.

Check the recording-consent rule. These tools record and transcribe every call by default, and call-recording consent rules vary by where you and your caller are: some places need both parties to agree, not just one. Before you go live, switch on the call’s recording notice or greeting disclosure, and check the rule for your state or country. It’s a two-minute setting that keeps a useful feature from becoming a liability.

Set it up so it actually works

The tool isn’t what determines whether this works. Your setup is, and it’s the part the vendor pages wave at. An AI receptionist answers from what you give it, so thin or out-of-date information produces a confident, wrong-sounding agent, the same way a support bot does when its help docs are bad. Our customer service comparison makes that case in full for chat; on the phone it’s the same job in three parts.

Write your real FAQs the way a caller asks them, not the way your website words them: hours, prices, service area, “do you do emergencies”, “how soon can someone come out”. Map the call flow you want, plainly: what the agent answers itself, what it books, when it transfers and to whom, and what it does after hours versus during the day. Then wire it to the calendar and CRM you genuinely use and test that a booking actually lands in the right place. Spend an afternoon on this before you forward a single real call, and the agent resolves the routine calls cleanly instead of fumbling them. Skip it, and no brand on the box will save you.

The build-it-yourself rung, and when it’s worth it

Past the packaged tools sits a level you build rather than configure, worth knowing about even if you never touch it. Instead of subscribing to a ready-made receptionist, you assemble your own voice agent on a platform like Vapi, Retell AI, Bland, Synthflow or ElevenLabs, connect it to a phone line through Twilio, and wire it straight into your own booking system and CRM. Synthflow goes furthest towards no-code, letting a non-developer assemble one through a drag-and-drop flow, while ElevenLabs brings the most natural voices, from about $22 a month, with the catch that you supply the language model and the phone line separately on top. These bill by the minute, very roughly $0.05 to $0.24 all-in once you add up the voice, the model, the speech-to-text and the phone line.

The maturity warning matters here. This is experimental next to a packaged tool, and it lives or dies on tuning: getting the response time low, stopping the agent talking over people, and making transfers reliable is genuine engineering, and the whole thing wobbles when one of those underlying services changes its API or its price. For nearly every small business, the sane move is to have a developer build it and hand it over once a packaged tool has proven the calls are worth automating, rather than learning to wire up telephony yourself. The oversight rule from the agentic AI guide still holds: a person approves anything that books money or makes a promise. This is where you head when you’ve outgrown the off-the-shelf options, not where you begin.

So, which one should you pick?

Pick by your call mix, then trial it on your own phone, not the vendor’s demo reel. A sole trader or small team who mainly needs the phone answered and a text with the details should start with Rosie at $49, the lowest-risk way in. A business that books appointments and wants a bill it can predict should trial Goodcall and weigh it against Rosie’s $149 plan. If a real share of your calls genuinely need a person, Smith.ai is worth the premium and the cheaper tools aren’t. Want it living inside a modern phone system? Look at Sona. Care most about a flat, no-surprises bill? Look at NextPhone.

Whichever you choose, the work that decides the result is yours, not the tool’s: your FAQs, your call flow and your calendar set up properly, and a clean handover for the calls the AI shouldn’t be taking. Get those right and a $49 plan beats a $299 one left on its defaults. None of this is about taking yourself off the phone. It’s about making sure the routine calls and the after-hours ones stop ringing out, so the jobs that used to die in voicemail come to you instead.
