An AI answering service for small business costs between $24.95 and $349 a month at list price in 2026, depending on whether the vendor bills per call, per minute, per unique caller or flat. The cheapest entry plan covers 30 calls; the most expensive self-serve plan covers 1,000 minutes. Every service below answers 24/7 and books appointments on at least one plan, so the decision comes down to pricing model, spam handling, booking depth and how much of your call volume the plan absorbs.
Prices were checked on each vendor's pricing page in the first week of September 2026. Stackbinary builds and operates its own voice AI platform (Oye Hello), which competes with every service in this list; the ownership route is discussed at the end, with a note on when it is not the right choice.

One paragraph per service
Upfirst is the lowest entry price with a full feature set: $24.95 for 30 calls, $59.95 for 90, $159.95 for 300 and $299 for 600, with a 14-day trial and no card. Per-call billing means a 12-minute call costs the same as a 1-minute one, and spam and sub-15-second calls are excluded.
Dialzara starts at $29 for 60 minutes and steps to $99 (220 minutes), $199 (500) and $349 (1,000). Overage drops from $0.48 to $0.35 a minute as you move up. Calendar sync is locked to the $99 plan and above, so the $29 tier is a message-taker rather than a booker.
Rosie offers 250 minutes for $49, the most generous allowance at the low end, with spam detection on every plan. Direct calendar booking and live transfers arrive on the $149 Scale plan (1,000 minutes); Growth at $299 adds 2,000 minutes. Overage pricing is not published.
Goodcall bills by unique caller rather than time: $79 a month per agent covers 100 unique numbers with unlimited minutes, $129 covers 250 and $249 covers 500, at $0.50 per extra caller. A repeat customer who calls ten times counts once, which suits businesses with a loyal base; a lead line where every caller is new pays full rate.
My AI Front Desk bundles voice, SMS, chatbot and email into $99 a month with 200 voice minutes, then meters at 25 credits a minute (about $0.25). The $20 Basic plan includes no voice minutes at all.
Smith.ai AI Receptionist has a free plan with 25 calls a month and $3 a call after that, a $150 Pro plan spanning 75 to 300 calls at roughly $2 a call, and a $500 Enterprise plan from 300 calls. Smith.ai also runs a human-staffed service from $300 for 30 calls, used below as the human benchmark.
NextPhone charges $199 a month flat for unlimited inbound calls with booking, CRM integration, recording and spam filtering included. No meter makes it the easiest bill to forecast and the most expensive option under about 100 calls a month.
Ringly starts at $349 for 1,000 minutes (about 500 calls) and $799 for 2,500, built around e-commerce order, return and product calls. It is priced for stores with a real call queue rather than a solo practice.
AI receptionist vs human answering service vs hiring
The table assumes a three-minute average call and the cheapest published plan at each volume. Human figures use Smith.ai's live-staffed plans ($300 for 30 calls, $810 for 90, $2,100 for 300, overage $8.50 to $11.50 a call); Ruby bills per receptionist minute at roughly $3.45 to $5 and lands in the same range. The in-house figure uses the BLS median receptionist wage of $18.27 an hour plus benefits and payroll tax, about $52,900 a year loaded.
| Calls a month | Per-call AI (Upfirst) | Per-minute AI (Dialzara) | Flat AI (NextPhone) | Human service (Smith.ai live) | In-house receptionist |
|---|---|---|---|---|---|
| 100 | $69.95 ($0.70/call) | $135 ($1.35/call) | $199 ($1.99/call) | $915 ($9.15/call) | $4,408 ($44/call) |
| 500 | $299 ($0.60/call) | $524 ($1.05/call) | $199 ($0.40/call) | $3,800 ($7.60/call) | $4,408 ($8.82/call) |
| 2,000 | About $1,279 at list overage, custom quote in practice ($0.64/call) | $2,099 ($1.05/call) | $199 ($0.10/call) | About $16,550 at list overage ($8.28/call) | $4,408 ($2.20/call), business hours only |
Two conclusions. AI is cheaper than a human answering service at every volume by a factor of 8 to 15. The in-house hire only becomes competitive above roughly 2,000 calls a month, and even then covers one shift. AI receptionist pricing compared walks the same ladder at a different volume set.
What to test before signing
Every service above offers a trial or a free plan. Use it to test the four things that decide whether the bill in the table is the one you get.
Spam. Call your own number from a blocked ID and a VoIP number. On per-call and per-minute plans, every robocall the AI picks up is billed unless the vendor excludes it. Upfirst and Smith.ai publish an exclusion policy; most others do not.
Accents and background noise. Have three people with different accents call from a car and a kitchen. Transcription quality is the difference between a booked appointment and a vague message.
Booking depth. Ask it to book, reschedule, then cancel. Several entry plans send a booking link rather than writing to the calendar; check which plan you are on.
CRM handoff. Confirm the call summary lands in your CRM with the caller's number and intent, not in an inbox. Many of these products run on platforms such as Vapi and Retell; voice AI pricing per minute explains what those platforms charge if you want to compare.
Owning the answering system, and the break-even volume
Read this section knowing Stackbinary sells the owned route through its AI call center service. For a practice taking under a few hundred calls a month with no CRM, no booking system and no compliance requirement, the SaaS route above is the right answer. Owning starts to make sense at four points.
Full data autonomy. Call recordings, transcripts, caller records and the booking pipeline live in your own system and cloud region, not in a vendor's tenant on a retention window you did not choose.
Only the features you use. A per-call or per-minute plan bills you for a bundle: chat widgets, SMS agents, unique-caller caps, tiers you grow through. An owned system carries the call flows you actually run and nothing else, and the running cost is the raw speech, model and telephony lines, typically $0.08 to $0.13 a minute with no plan tier on top.
Your own system, our team managing it. Owning does not mean hiring engineers. Stackbinary builds the system and runs it: hosting, monitoring, model updates and the integrations to your calendar and CRM.
Lower cost and fast delivery. Fixed-price proposal within 48 hours, 55+ shipped products, delivery in weeks, IP assigned to you on payment. The build is SOC 2-aligned and HIPAA-ready, so clinics do not pay a compliance surcharge per month.
The break-even is a volume question. Below 500 calls a month the SaaS table above is hard to beat. Once the monthly bill passes roughly $1,000, or the service needs to write to your CRM, check insurance or route by customer record, the owned route usually pays back within the first year.
Send us your call volume and we will return a fixed price within 48 hours.
FAQ
How much does an AI answering service cost for a small business?
Between $24.95 and $349 a month at list price. Per-call plans start at $24.95 for 30 calls (Upfirst), per-minute plans at $29 for 60 minutes (Dialzara), per-caller plans at $79 for 100 unique callers (Goodcall), and flat unlimited plans at $199 (NextPhone).
What is the difference between AI receptionist pricing per call and per minute?
Per-call pricing charges the same for a 1-minute and a 12-minute call, so it suits long conversations; per-minute pricing suits short calls. At a three-minute average, per-call AI works out at $0.60 to $0.70 a call and per-minute AI at $1.05 to $1.35.
Is an AI phone answering service cheaper than a human answering service?
Yes, by a factor of 8 to 15 at the same volume. At 100 calls a month, per-call AI costs about $70 against about $915 for a human-staffed service, and at 500 calls about $299 against $3,800.
Can an AI answering service book appointments?
Yes, but not always on the entry plan. Upfirst, Goodcall, NextPhone and Smith.ai include booking on every plan; Dialzara needs the $99 plan and Rosie the $149 plan for direct calendar writes.
