Short answer
An AI answering service costs about $0.15 to $0.50 a minute on published plans, while a live answering service costs about $1.20 to $5.00 a minute. At 500 calls a month that's roughly $130 to $800 for AI, $1,250 to $1,850 for a hybrid that sends the hard calls to people, and $1,400 to $3,800 for live receptionists.
AI handles routine calls well: questions, messages, booking and routing, day and night. People still win with upset callers and calls that need judgment. For most businesses that already pay a live service, a hybrid is the right first move. Every price below comes from the vendor's own pricing page, checked October 23 and 24, 2026.
| At a glance | AI answering | Hybrid (AI first) | Live answering |
|---|---|---|---|
| Typical price | $0.15–$0.50/min or $0.40–$2.00/call | $2.50–$3.70/call | $1.20–$5.00/min or $7–$10/call |
| Entry plan | $24.95/mo for 30 calls | about $117/mo for 30 calls | $99/mo for 50 minutes |
| Answers | Every call at once, 24/7 | AI first, people take over | One receptionist per call, 24/7 |
| Best at | FAQs, messages, booking, routing | Mixed call types | Upset or complex callers |
| Weak at | Judgment, angry callers, noisy lines | Costs more than AI alone | Price, spam eating minutes |
What is an AI answering service?
An AI answering service, also sold as an AI phone answering service or AI call answering service, is a voice agent that picks up your business line, talks with the caller in a natural voice, and then takes a message, answers questions, books an appointment or transfers the call. It's the same idea as an AI receptionist, sold as a monthly plan. A live answering service does the same job with human receptionists working from a call center. A hybrid uses AI first and hands some calls to those people. How the parts fit together is in what an AI voice agent is, and every other way to put AI on your phones is in our guide to AI voice agents for business.
AI vs live answering service: what each handles
A live answering service handles the hardest quarter of calls better, and an AI answering service handles the routine rest at a fraction of the price, with no hold queue. Smith.ai, which sells both, says "about 25% of AI-led calls usually require a live agent" on its hybrid pricing page.
What an AI call answering service does well
An AI call answering service is strongest on repeatable calls. Published plans answer FAQs from your website, take messages, qualify leads, book onto Google or Outlook calendars, text callers a link and route calls by name or department. Upfirst books on Google, Outlook, Calendly, Acuity and Square and speaks 35+ languages; RingCentral AI Receptionist switches between six languages mid-call.
Where AI phone answering falls short
AI phone answering struggles where a good receptionist earns their pay: angry callers, emergencies, judgment calls and bad lines. Retell warns its noise filter can mistake a soft-spoken caller for background noise, and Vapi's turn detection works in English only. Callers notice too: in a Gartner survey of 5,728 customers, 64% said they'd prefer companies didn't use AI in customer service.
How to choose an AI answering service for business
Choose an AI answering service for business by its fine print, not its headline price. Five things on the pricing page decide it:
- Billing unit. Per minute, per call or per unique caller (prices below).
- What isn't billed. Upfirst skips spam and calls under 15 seconds. Smith.ai filters known spammers and lets you remove up to 10% of calls each cycle.
- Transfers. On Rosie, warm transfers start on the $149 plan; Dialzara lists warm transfer on its $349 plan. Make sure the plan you're quoted can hand a caller to a person.
- Your calendar and CRM. Smith.ai's free and Pro plans include native integrations like Calendly, Clio and Zapier, but custom integrations need Enterprise at $500 a month.
- Contract. Smith.ai's AI plans are month-to-month with 30 days' notice to cancel.
How much does an answering service cost?
An answering service costs from about $25 a month for an entry AI plan to $99 to $350 for an entry live plan, and the bill then grows with every minute or call. The unit matters as much as the price: per minute, per call, or per unique caller.
Virtual answering service pricing
Virtual answering service pricing with live receptionists works out to $1.20 to $5.00 a minute. The fine print on what counts as a minute changes the bill as much as the rate.
| Live service | Entry plan | Per minute | How time is billed |
|---|---|---|---|
| Ruby | $250 for 50 min | $3.45–$5.00 | Rounded up to 60 s, hold time billed |
| Abby Connect | $164 for 50 min | $2.76–$3.29 | 30-second steps |
| PATLive | $99 for 50 min | $1.50–$1.98 | First minute full, then 6 s; no wrap-up time |
| AnswerConnect | $350 for 200 min | $1.32–$1.75 | Whole minutes, after-call work billed |
| Specialty Answering Service | $159 for 100 min | $1.20–$1.59 | Per second |
| Smith.ai Human-first | $300 for 30 calls | $7–$10 a call | Per call; no charge for spam |
Per-minute rates are the plan price divided by its minutes. A 70-second call shows why billing rules matter: it bills as 2 minutes at Ruby (about $7.20 on its 200-minute plan) but about 1.2 minutes at PATLive (about $2.10). Ruby's billing help page also counts hold time, and AnswerConnect only waives the first 30 calls under 30 seconds each month, so robocalls and wrong numbers can eat paid minutes.
AI answering service cost
AI answering service cost runs about $0.15 to $0.50 a minute, or $0.40 to $2.00 a call, before overage.
| AI service | Entry plan | Effective rate | What isn't billed |
|---|---|---|---|
| Upfirst | $24.95 for 30 calls | $0.50–$0.83 a call | Spam, calls under 15 s, silent calls |
| Goodcall | $79 for 100 callers | $0.15–$0.79 a caller | Repeat callers that month, spam, wrong numbers |
| Rosie | $49 for 250 min | $0.15–$0.20 a min | Spam filtered (billing rule not published) |
| Dialzara | $29 for 60 min | $0.35–$0.48 a min | Not published |
| RingCentral AIR | $49 for 100 min | $0.49 a min, $0.50 over | Not published; 30 s rounding |
| Smith.ai AI-first | Free for 25 calls | $1.60–$3.00 a call | Known spammers; up to 10% of calls removable |
AI phone answering service vs live at 200, 500 and 1,500 calls
An AI phone answering service costs about $130 to $385 a month at 200 calls, against $580 to $1,965 for live receptionists. The gap widens with volume. We assumed each call bills 2 minutes after rounding (no vendor publishes average call length), used the cheapest mix of plan and overage at list price, and counted every Goodcall caller as new.
| Service | 200 calls | 500 calls | 1,500 calls |
|---|---|---|---|
| Smith.ai Human-first (live) | $1,965 | $3,800 | $12,300 |
| Ruby (live) | $1,725 | Overage not published | Overage not published |
| PATLive (live) | $668 | $1,499 | $4,299 |
| AnswerConnect (live) | $580 | $1,418 | $4,300 |
| Smith.ai Hybrid | From $500 | $1,250–$1,850 | From $3,750 |
| Smith.ai AI-first | $385 | $800 | Custom |
| RingCentral AIR (AI) | $199 | $499 | $1,499 |
| Dialzara (AI) | $180 | $349 | $1,049 |
| Upfirst (AI) | $160 | $299 | $929 |
| Rosie (AI) | $149 | $149 | $299 plus overage |
| Goodcall (AI) | $129 | $129 | $299 |
Smith.ai's 500-call hybrid range comes from its own calculator; the 200 and 1,500-call figures use its published "from" rate of $2.50 a call. At 1,500 calls, Smith.ai also offers Enterprise pricing on request. Rosie publishes no overage rate. Taxes and AnswerConnect's $49.99 setup fee on some plans are extra.
Smith.ai pricing and the hybrid option
Smith.ai pricing is the clearest view of all three models, because it sells them side by side: AI-first from $1.60 a call, hybrid from about $2.50 and human-first from $7.
Source: Smith.ai hybrid pricing page, October 23, 2026.
In Smith.ai's hybrid, the AI answers every call and a live agent takes over by rule: new callers only, new and existing clients, or every call during business hours. A call the AI hands to a person still counts as one call, so the bill doesn't double. At 300 calls a month, that's $771 to $1,131.
Two other services publish a hybrid. Abby Connect uses one pool of minutes, where an AI minute uses half a human minute and you set which call types go to people. Moneypenny sells AI plans from $99 for 50 calls with human escalation, but doesn't publish what an escalated call costs. Ruby and PATLive are human-answered; Ruby uses AI only to support its receptionists.
Is there a free AI answering service?
Smith.ai's AI Receptionist is the one free AI answering service among the plans we checked: 25 real calls a month at no charge, then $3.00 a call. The free plan includes 24/7 answering, recordings, transcripts, routing and calendar booking, but no custom prompts and no live support.
The rest offer trials. Upfirst gives 14 days with no credit card, and Rosie and Dialzara give 7. Goodcall lets you build and hear a demo agent for free and bills once you connect a number. A free plan only fits a business with a handful of calls: at 200 calls a month, Smith.ai's free plan would bill $525, against $385 on its paid Pro plan.
After hours answering service: AI or live?
AI is the better after hours answering service for most businesses. Every AI plan we checked answers 24/7 at no extra charge, and most after-hours calls are messages, bookings and "are you open tomorrow". Live services include nights and weekends too, but on most per-minute plans a 2 a.m. robocall still burns paid minutes. Keep a person on call only if after-hours calls are real emergencies, which a script should route straight to your on-call phone.
Can AI answer phone calls legally?
Yes. AI can answer your business calls, and the FCC's 2024 ruling on AI voices doesn't cover calls a business receives. That declaratory ruling (FCC 24-17) applies to "any AI technology that initiates any outbound telephone call", so an AI that calls leads back is covered by the TCPA's consent rules; more in our TCPA rules for sales calls.
Two other rules do touch inbound answering:
- Recording. AI services record and transcribe calls. Federal law needs one party's consent, but California, Connecticut, Florida, Illinois, Maryland, Massachusetts, Montana, New Hampshire, Pennsylvania and Washington require everyone's. A recording notice at the start of the call is the usual answer.
- Saying it's AI. Utah requires a business to disclose AI when a caller clearly asks, and Maine bars chatbots, including voice ones, from leaving a consumer thinking they're talking to a person. Saying so up front may even help: Upfirst's own analysis of 450,702 calls linked disclosing the AI with about 20% fewer hang-ups.

Best AI answering service for small business: which to pick
The best AI answering service for small business is the one billed on the unit your calls favor: per call (Upfirst) for short, simple calls, per caller (Goodcall) for long or repeat callers, and a hybrid (Smith.ai) when some calls need a person. The best answering service for small business overall follows the same rule, with live receptionists kept for complex intake.
| Your calls | Pick |
|---|---|
| Under about 200 a month, mostly simple | An AI service on a per-call plan |
| Long calls, many repeat callers | A per-caller AI plan like Goodcall |
| Mixed, some high-value or upset callers | A hybrid, or AI that warm-transfers to your own staff |
| Complex intake, callers who won't talk to a bot | A live service, ideally one billing in short increments |
Switch from live to AI when most of your paid minutes are messages and bookings, or spam. Stay live, or go hybrid, if a mishandled call costs you more than a month of the service. If you're still choosing a vendor, our best AI receptionist roundup and the small business guide compare them feature by feature.
Should you own your AI phone answering?
Rent if your answering bill is a few hundred dollars a month: an AI service at $130 to $400 is hard to beat, and owning won't pay off. Owning starts to make sense at high volume, or when the agent has to work inside your own CRM, calendar and job records.
The parts an AI agent runs on are cheap. A Twilio local number is $1.15 a month and inbound calls $0.0085 a minute. Deepgram transcribes speech for $0.0048 a minute at its current promotional rate and voices replies for $0.030 per 1,000 characters. Hosted platforms add a fee on top: Vapi $0.05 a minute, Retell $0.055, ElevenLabs $0.08. Answering services charge $0.15 to $0.50 a minute and up, every month, for as long as you use them.
When you own it, the agent's logic, scripts, call recordings and transcripts sit on your own hosting. The phone carrier and AI model are still rented, billed at cost, and you can swap either. With an owned build, the code, data and IP are yours, and they stay yours if you part ways with us. The full rent-vs-own math is in what an AI receptionist costs, and how pricing works explains ours: typically less than you spend today, and the build payments have an end date.

Frequently asked questions
How much do virtual receptionists cost?
Live virtual receptionists cost about $1.20 to $5.00 a minute on published plans, or $7 to $10 a call on Smith.ai's human plans. Entry plans start around $99 to $350 a month. AI receptionists cost about $0.15 to $0.50 a minute, with plans from $25 to $150 a month.
How much does an AI phone answering service cost?
An AI phone answering service costs about $0.15 to $0.50 a minute, or $0.40 to $2.00 a call, on published plans. Entry plans run from $24.95 a month for 30 calls at Upfirst to $79 for 100 callers at Goodcall. At 500 calls a month, AI plans come to roughly $130 to $800.
What is the best AI answering service?
There isn't one best service, because they bill on different units. At low volume, per-call plans like Upfirst are cheapest. For long calls, per-caller pricing like Goodcall's wins. If you need live people behind the AI, Smith.ai or Abby are the ones that publish a hybrid plan.
Is an AI answering service good for a small business?
Yes, for routine calls: hours, directions, messages, booking and routing, around the clock, at a fraction of a live service's price. It's weaker with upset callers and judgment calls, so many small businesses pair it with a person, either their own staff or a hybrid plan.
