AI answering service: what it actually costs
Links marked "Ad" are affiliate links: if you sign up through one, we may earn a commission at no extra cost to you. Commission never changes what we recommend.
An AI answering service is software that picks up your phone, understands the caller and responds, without a person involved. Published plans among the 9 vendors we track run from $24.95 a month at Upfirst to $199 at NextPhone, and the honest working range for a small business sits closer to $49 to $199. The word "answering" also matters: it is a narrower job than a full AI receptionist, and mixing the two up is how buyers end up on a plan that cannot book an appointment.
Prices read from each vendor's own pricing page in October 2026. Some links on this page are affiliate links, which never change what we say about a price. Full picks and reasoning: best AI receptionists in 2026. Cost broken down by call volume: what an AI receptionist costs.
What is the difference between an AI answering service and an AI receptionist?
Vendors use both terms to sell the same product, so the label on the page tells you very little. The useful distinction is what the software actually does once it has the caller on the line. An answering service captures the call: who called, why, and a message if nobody is available. A receptionist does more of the front-desk job: it checks a calendar, books a slot, transfers a live caller to a person, or writes the result into a CRM. Plenty of products do both, priced as one tier above the other.
Rosie makes the split visible inside its own price ladder rather than across two different vendors. Professional at $49 a month is answering in the narrow sense: message taking, spam filtering, app, English and Spanish. Scale at $149 a month is the same voice and the same phone number, but it adds calendar booking and warm transfers to a human, which is the moment it becomes a receptionist rather than an answering line. Ask any vendor the same question before you buy: does it just take a message, or does it act on what the caller wants?
Watch the branding, not the name. Dialzara's AI SMS Agent at $19 a month sits on the same pricing page as its phone plans and answers no phone calls at all: two-way SMS only, no phone answering: $0.05 per AI message plus carrier fees of $0.0083 per segment. There is no cheap way in any more. The $20 Basic plan, which answered no phone calls, is gone as of September 2026, so the entry price for voice answering is $99 a month ($79 billed annually). The company now brands itself Frontdesk, though the site still lives at myaifrontdesk.com. A product named "front desk" or "receptionist" is not proof it answers the phone. Check the plan, not the company name.
What does an "AI phone answering service" actually include?
Adding "phone" to the search narrows it correctly: you want voice calls answered, not a chatbot or a text inbox wearing an AI receptionist's branding. That distinction is worth checking line by line, because several vendors in this market sell phone, SMS and web chat as one bundle and do not always make clear which channel a given price actually covers. Dialzara pricing is the clearest example: its $19 AI SMS Agent answers no phone calls at all (two-way texts only), and voice answering starts at $29 a month for 60 minutes on Business Lite, then $0.48 a minute. If a phone number that actually rings and gets answered is the point, price the plan that states voice minutes, not the cheapest number on the page.
Which AI answering services could we verify?
Sorted by entry price. "Entry plan" means the cheapest tier that actually answers a phone call, so plans like Dialzara's AI SMS Agent that cover no voice minutes are excluded here and priced separately above.

|---|---|---|---|---|
| Upfirst | Starter | $24.95/mo | 30 calls a month | per call |
| Dialzara | Business Lite | $29/mo | 60 minutes | per minute |
| Rosie | Professional | $49/mo | 250 minutes | per minute |
| Answrr | Solo | $49/mo | 250 minutes (4h 10m) | per minute |
| Simple Phones | Basic | $49/mo | 100 calls a month | per call |
| Goodcall | Starter | $79/mo | 100 unique customers | per customer |
| My AI Front Desk | Business-in-a-Box | $99/mo | 200 voice minutes | credits |
| NextPhone | Pro | $199/mo | unlimited calls | flat rate |
| Slang.ai | Core | Quote only | per location, by quote | per location |

How do AI answering services actually charge you?
Four billing shapes cover almost every plan in this market, and the shape matters more than the sticker price once your call volume is real rather than a demo.
Per minute
A bundle of minutes, then a published rate above it. Rosie, Dialzara and Answrr all work this way. Answrr charges $0.25 a minute over its smallest plan; Dialzara charges $0.48 on its smallest plan. Cheap when call volume is steady, expensive the month it is not.
Per call
A bundle of calls rather than minutes, so a 40-second call and a 6-minute call cost the same. Simple Phones sells $49 for 100 calls a month; Upfirst sells $24.95 for 30 calls a month, then $1.50 per extra call, and does not bill calls under 15 seconds. This shape suits businesses with many short calls, since length stops being the variable that matters.
Per customer
Goodcall bills $79 a month for 100 unique customers, with unlimited minutes included and $0.79 for every unique caller past the limit. Three calls from the same person in one week cost nothing extra, which no per-minute plan can offer.
Flat rate
One price, unlimited calls, no overage line at all. NextPhone's Pro plan is $199 a month, the same bill whether the month is quiet or the phone never stops. The entry price is higher; the ceiling does not exist.
Two more shapes exist outside those four: My AI Front Desk sells a credit pool instead of plain minutes, and Slang.ai prices per restaurant location and now quotes every plan privately, not per call at all. Neither compares cleanly to a minute bundle until you convert it, which is exactly what the hidden costs page does.
When is an answering service not enough?
If your calls need booking, live transfer to a person, or a write into your calendar and CRM, price the tier above the cheapest one rather than assuming the vendor's entry plan does it. Our full picks by use case, including which vendor is cheapest at volume and which one is safest if you might want a human backup, are on best AI receptionists in 2026. For the same comparison against human answering services rather than against other AI vendors, see AI receptionist against answering service.
Is any of this worth paying for?
Only if the calls you are missing are worth more than the plan. Put your own numbers in below before you pick a vendor from the table above.
You miss about 10 calls a week, and roughly 3 of those callers would have booked.
Estimate from the numbers you enter, not a forecast or financial advice. Check your own call logs and the vendor's terms.
Next step: compare 24/7 live and hybrid answering services, or look at Smith.ai (AI with live agents behind it, live plans from $300 a month, price checked Oct 23, 2026).

Frequently asked questions
What is an AI answering service?
Software that picks up your business calls, understands what the caller wants and responds with a voice, without a person on the other end. Published plans in our data run from $24.95 a month at Upfirst up to $199 at NextPhone, though most working plans for a small business sit closer to $49 to $199. "Answering" is the narrower half of the job: capturing the call and the message. Booking, transfers and CRM writes are what turn an answering tool into a full AI receptionist, and not every plan includes them. Verified October 2026.
What is the difference between an AI answering service and an AI receptionist?
Mostly marketing, but one vendor's own tiers make the practical difference visible. Rosie's Professional plan at $49 a month only takes messages: message taking, spam filtering, app, English and Spanish. Its Scale plan at $149 a month is the same product doing more of a receptionist's job: adds calendar booking and warm transfers to a human. If a vendor cannot tell you whether their AI books appointments or transfers a caller to a person, you are looking at an answering tool, whatever the marketing page calls it.
How much does an AI answering service cost?
$24.95 to $199 a month across the 8 vendors that publish a price, but the cheapest headline is rarely the cheapest real plan. Upfirst's Starter at $24.95 holds 30 calls a month, and Dialzara's Business Lite at $29 holds 60 minutes, which at a 3-minute average call is about 20 calls a month, close to one call a working day. A plan built for real weekly call volume usually starts nearer $49 to $199.
Do AI answering services charge per minute or per call?
Both exist, plus two other shapes entirely. Rosie, Dialzara and Answrr sell bundles of minutes. Dialzara and Answrr publish a per-minute overage (Answrr charges $0.25 a minute over its smallest plan); Rosie has none and moves you up to its next plan instead. Simple Phones and Upfirst sell bundles of calls instead: $49 for 100 calls a month at Simple Phones, $24.95 for 30 calls a month at Upfirst, then $1.50 per extra call. Goodcall charges per unique caller with unlimited minutes: $79 for 100 unique customers, then $0.79 per extra caller. NextPhone skips the arithmetic: $199 flat for unlimited calls, no overage line at all.
