AI receptionist and AI answering service for small business: AI phone answering service pricing compared
What the main AI answering services actually charge, taken from their own pricing pages rather than a roundup, plus the arithmetic that shows why two products with similar headline prices can differ by ten times on the same call volume. If you already know the off-the-shelf ones cannot reach your booking system, describe the build in the brief.

the short answer
An AI receptionist is software that answers your business phone, holds a real spoken conversation, and finishes the job the caller rang about: booking the appointment, taking the message, or transferring to a person with context. In August 2026, vendor-published pricing starts at $29 a month (Dialzara, 60 minutes) and $49 a month (Rosie, 250 minutes), while Smith.ai, which puts human agents behind the AI, starts at $300 a month for 30 calls. The trap is the unit: per-minute plans and per-call plans are not comparable, and at roughly 100 calls a month the same workload costs about $49 on Rosie and about $915 on Smith.ai. Buy off the shelf when you need answer, qualify, book and transfer against a mainstream calendar. Build your own when the receptionist has to reach software the vendors do not integrate with, or when a signed BAA and controlled audio handling are non-negotiable.
Every price below was read off the vendor's own pricing page in August 2026 and is labeled as published or not published. Blended figures are arithmetic from those published rates and are marked as modeled. This category changes pricing often, so confirm the current number before you sign anything.
01 / the comparison
AI receptionist pricing compared: what each one publishes
Read the middle column before the price column. A plan sold in minutes and a plan sold in calls look similar on a comparison chart and behave nothing alike once real callers start ringing.
| Service | Priced by | Published tiers | Overage | Best for |
|---|---|---|---|---|
| Dialzara | Receptionist minutes | Published. $29 (60 min), $99 (220), $199 (500), $349 (1,000) per month | $0.48 to $0.35 per minute, falling as the tier rises | Spiky volume, because the cost of going over is stated up front |
| Rosie | Receptionist minutes | Published. $49 (250 min), $149 (1,000), $299 (2,000) per month | Not published on the pricing page. Ask before you commit | Most included minutes per dollar at the entry tier |
| Smith.ai | Calls, with human agents behind the AI | Published. $300 (30 calls), $810 (90), $2,100 (300) per month, plus custom enterprise | $11.50, $10.50 and $8.50 per extra call by tier | High-value calls where a human must catch anything the AI misses |
| RingCentral AI Receptionist | Standalone or add-on license | Not published. The pricing page routes you to a sales conversation | Not published | Companies already standardized on RingCentral phone service |
| Custom build | One-off build, then your own telephony and model usage | No subscription tier. You pay to build it, then pay providers at cost | None. Usage is billed by your telephony and model vendors directly | Integrations nobody supports, strict compliance, or high steady volume |
Smith.ai is in a different product class and the price gap is not a rip-off, it is people. Trained human agents pick up what the AI cannot, which is worth $11.50 a call for a law firm where one missed intake is worth thousands, and is poor value for a salon booking haircuts. For the wider voice engineering picture, see AI voice agent development, and for what the technology is doing under the hood, what is an AI receptionist. The human side of that trade has its own rate cards, running roughly $1.20 to $5.00 a minute against the figures above, and one provider now prices both halves in the same unit: Abby Connect counts an AI handled minute as half an Abby Minute, which values its own human handling at exactly twice AI handling on the same account. Those plans are compared on the virtual receptionist services pricing page.
02 / the arithmetic
The same 100 calls a month, priced on every model
A typical small business inbound call runs about two and a half minutes, so 100 calls is roughly 250 receptionist minutes. That single assumption is enough to expose the real spread. The figures below are modeled from the published rates in the table above, not quoted by the vendors.
| Service | Tier that fits | Modeled monthly cost | How it gets there |
|---|---|---|---|
| Rosie | Professional, $49 | about $49 | 250 included minutes covers 250 minutes exactly, with no headroom |
| Dialzara | Business Pro, $99 | about $113 | 220 included minutes, then 30 minutes over at $0.45 adds $13.50 |
| Smith.ai | Basic, $810 | about $915 | 90 included calls, then 10 calls over at $10.50 adds $105 |
| Custom build | No tier | build cost, then usage at provider rates | Telephony and model usage billed directly, with no vendor margin on top |
Two honest caveats. Rosie at exactly 250 minutes has zero slack, so a busy month pushes you to the $149 tier and the real answer is somewhere between. And Smith.ai at $915 is buying human labor, so the correct comparison for that spend is a part-time receptionist, not another piece of software. The reason to model this yourself is that the cheapest vendor changes depending on your average call length, which is the one number no roundup knows about your business.
03 / capability
What an AI answering service does well, and what it hands back
The demo videos all show the same clean booking call. The useful question is what happens on the messy ones, because that is where a front desk earns its keep.
[ answering ]
Every call, at once, at 2am
The genuine advantage over a human front desk is not intelligence, it is concurrency and hours. Ten callers at 9am on Monday all get picked up on the first ring, and the after-hours calls that used to go to voicemail get handled instead of lost.
[ booking ]
Writing into the real calendar
It detects booking intent, gathers the details, checks live availability and writes the appointment. This only works as advertised when the integration reaches your actual scheduling system. A booking flow reading a stale copy of your availability creates double bookings.
[ qualifying ]
Screening before the transfer
Asking three qualifying questions and attaching the answers to the transfer is where most of the time saving hides. Your team stops taking calls that were never going to be a job, and picks up the ones that are with the context already gathered.
[ routing ]
Warm transfer, not just forwarding
A cold transfer dumps the caller on whoever picks up. A warm transfer briefs the person first. A waterfall transfer works down a list until someone answers. These are usually gated by tier, so check which one you are actually buying.
[ limits ]
Where it should give up
Angry callers, emergencies, anything with legal or medical consequence, and any caller who says the word human. A receptionist that fights to keep the call is worse than no receptionist. Configure the handoff triggers on day one and test them deliberately.
[ records ]
The transcript nobody expected to want
Every call arrives transcribed and summarized, which turns the phone line into a searchable record of what customers actually ask. Several teams end up valuing this more than the answering itself, because it tells them what to fix on the website.
04 / the honest part
Where an AI receptionist quietly costs you customers
A comparison page that finds no downside is a brochure. Four failure modes account for most of the cancellations in this category, and only one of them is really the vendor's fault.
01
The integration was a screenshot
Vendors list logos for scheduling and CRM tools, but depth varies enormously. Reading availability is not the same as writing a booking, and writing a booking is not the same as respecting your provider rules, room constraints or buffer times. Test a real booking end to end during the trial, not a demo one.
02
Nobody configured the escalation
Out of the box these systems try hard to handle the call themselves, which is exactly wrong for an emergency or a furious customer. Every complaint you will read about AI receptionists is really a complaint about a missing handoff rule. Write the triggers down before launch.
03
The pricing unit did not match the calls
A per-minute plan punishes businesses with long consultative calls. A per-call plan punishes businesses with lots of quick ones. Pick the wrong unit and you can pay several times what the same service costs on the other model, which is the whole point of the arithmetic above.
04
Compliance was assumed, not signed
A medical or dental practice routing patient calls needs a signed business associate agreement covering recording, transcription and storage, including any model provider in the chain. Marketing copy saying HIPAA-friendly is not an agreement. Get it in writing or do not route the call.
05 / build or buy
When to buy an AI receptionist, and when to build your own
Buying is the right default and we will say so plainly. At $49 a month nobody should commission software. The exceptions are specific, and they are all about reach, rules or volume.
| If your situation is | Do this | Why |
|---|---|---|
| Answer, qualify, book into Google Calendar or Calendly, transfer the rest | Buy a published tier | This is the exact motion the products were built for, and it costs less per month than an hour of engineering |
| The booking has to land in a practice management or field service system nobody integrates with | Build a custom agent | Without a real write path the AI takes a message instead of booking, which removes most of the value you were paying for |
| Regulation controls where call audio and transcripts may go | Build, with a controlled data path | A subscription cannot solve a data residency constraint. Similar reasoning applies in AI for financial services |
| Thousands of minutes a month, steady | Model both, then decide | Per-minute pricing rises forever while a build is paid once. Read build vs buy an AI agent |
| You are not sure callers will accept it at all | Buy the cheapest monthly tier first | Find out with a $29 test on your real calls before anyone writes code or signs an annual contract |
| You need outbound calls too, not just answering | AI voice agent development | Outbound calling carries its own consent and compliance rules and is a separate build from an inbound receptionist |
A custom AI receptionist is a mid-sized build rather than a research project: a telephony number, a speech pipeline, a model with your business rules, tool calls into your calendar and CRM, and a transfer path. Most of the engineering risk sits in evaluation, which is why it is worth reading how to evaluate an AI agent before you ship it and how long it takes to build an AI agent before anyone starts.
06 / who it fits
AI receptionist for small business, by the kind of business
The same product is a bargain in one industry and a liability in another. What changes is the value of a single missed call and how much regulation sits on the conversation.
[ medical + dental ]
Highest value, highest bar
Appointment-heavy, phone-first, and losing bookings to busy signals at peak hours. Also the hardest to do correctly, because you need a signed business associate agreement and a write path into the practice management system, not just a calendar link.
[ home services ]
The clearest win
Plumbers, HVAC and electricians lose jobs to whoever answers first, and are on a roof when the phone rings. Emergency triage matters more than booking here: get the urgent ones to a human fast and schedule the rest.
[ legal ]
Screen, never advise
One retained client covers years of subscription, so the economics are easy. The rule is strict: the AI collects intake details and conflicts information and hands off. It must never come close to answering a legal question.
[ salons + fitness ]
Volume, low stakes
High call counts, short calls, simple bookings and forgiving customers. This is the profile where a cheap per-minute plan wins outright and where an AI receptionist needs the least configuration to be useful.
[ real estate ]
Qualification is the product
Inbound property enquiries are mostly people who will never transact. Capturing budget, timeline and financing status before anything reaches an agent is worth more than the answering itself.
[ poor fit ]
When to skip it
Low call volume where the owner answers anyway, callers in genuine distress, and anything where every conversation is unusual. If you cannot name three calls that repeat every week, there is nothing here to automate yet.
Home services buyers should price the live options alongside the automated ones before deciding, since emergency triage is the one task where paying for a human still wins clearly. The published rates for that market are in the HVAC answering service comparison for contractors. Healthcare is different enough to need its own numbers, because the specialist providers publish compliance credentials the general products do not, and they price higher for it. We compared them separately on the medical answering service page, including one vendor that sells human and AI answering side by side, and the dental-specific version in the dental answering service guide. If what you actually need is evening and weekend cover rather than a full time receptionist, the economics change completely, because low after hours volume means you pay for minutes you never use: that math is worked through on the 24/7 answering service for small business page.
07 / why botgigs
If the answer is build, this is where you find the people who have built one
01
We will tell you to buy when buying is right
Most businesses reading this should sign up for a $49 plan and be done by Friday. We are not selling the subscription and have no affiliate deal with any vendor above, which is why the pricing table says what it says. Bring us the calls the products cannot handle.
02
Selected for AI work, not all work
A general freelance network has to cover design, finance and mobile. This pool covers AI, agents and automation, so a shortlist for a voice build is people who have shipped one. Browse it on the marketplace, or hire through an AI agent development company.
03
Scoped before you spend
The hire brief turns "we want an AI receptionist" into deliverables and an honest effort band, so you can weigh a build against the subscription math above using the same numbers. See how hiring works and how to write an AI project brief.
04
Priced in public
The hire fee is on the pricing page: free to post at 10 percent, or 7 and 5 percent on the paid plans. Given that one of the vendors above will not quote you without a sales call, knowing the number up front is the point. For the wider picture see conversational AI companies.
[ Botgigs is in early access. The plans above are the published launch tiers and nothing is billable today, which we would rather say plainly than imply a track record we have not earned yet. ]
08 / questions
AI receptionist questions buyers actually ask
What is an AI receptionist?
An AI receptionist is software that answers your business phone line, holds a natural spoken conversation with the caller, and completes the task the caller wanted: booking an appointment, taking a message, answering a common question, or transferring to a person with context attached. It runs around the clock and handles several calls at once, which is the part a single front desk cannot do.
How much does an AI receptionist cost?
Vendor-published entry pricing starts near $29 a month. Dialzara publishes $29 for 60 minutes up to $349 for 1,000 minutes. Rosie publishes $49 for 250 minutes up to $299 for 2,000. Smith.ai, which puts human agents behind the AI, publishes $300 for 30 calls up to $2,100 for 300. The pricing model matters more than the headline number.
How does an AI receptionist work?
It converts the caller speech to text in real time, uses a language model to work out what the caller wants, then either answers from your business information or calls a tool such as your calendar or CRM to complete the task. Anything it cannot handle is transferred to a person along with a summary of what was already said.
Can an AI receptionist book appointments?
Yes, when it is connected to your scheduling system. It detects booking intent, collects the details it needs, checks live availability in the connected calendar or practice management system, then writes the appointment and confirms it by text. The integration is the hard part: a booking feature that cannot read your real availability just creates double bookings.
Is an AI receptionist worth it?
It is worth it when you are losing revenue to unanswered calls and your calls are repetitive. A service business that misses calls after hours recovers bookings it was already losing. It is not worth it when call volume is low, when every call is unusual, or when your callers are in distress and need a person immediately.
Can an AI receptionist transfer calls to a human?
Every serious product supports transfers, but they differ in quality. A cold transfer just forwards the call. A warm transfer briefs your team on what the caller wants before connecting. A waterfall transfer tries several numbers until someone picks up. Check which type is included in your tier, because warm and waterfall transfers are often gated to higher plans.
What is the best AI receptionist for small business?
There is no single best one because they price on different units. Rosie gives the most included minutes per dollar at the entry tier. Dialzara publishes the clearest overage rates, which matters if your volume is spiky. Smith.ai is the choice when you want humans to catch what the AI cannot. A custom build wins when the receptionist has to work inside software none of them integrate with.
Is an AI receptionist HIPAA compliant?
Only if the vendor signs a business associate agreement and configures the call recording, transcription and storage path to match. Do not assume it: a general purpose AI answering service that routes audio through third-party model providers without a signed BAA is not compliant for a medical or dental practice, regardless of what the marketing page implies. Ask for the BAA in writing before you route a single patient call.
Should I buy an AI receptionist or build one?
Buy when your needs are standard: answer, qualify, book into a mainstream calendar, transfer the rest. Build when the receptionist has to read or write to software the vendors do not integrate with, when regulation forbids sending call audio to a third party, or when your call volume is high enough that per-minute pricing costs more than owning the stack.
Will callers know they are talking to an AI?
Most will work it out within a sentence or two, and trying to hide it backfires. The businesses that get the best reception state it plainly in the greeting and make the route to a human obvious and fast. Several states also have disclosure rules for automated calls, so check the requirement in the states you operate in.
