How Much Does an AI Receptionist Cost?

Most AI receptionists run $50 to $300 a month. The number that matters is what your call pattern costs under each vendor's billing model, and those differ more than the prices do.

By the BookLine AI team · August 21, 2026

Comparing AI receptionist pricing is harder than it should be, because vendors don't meter the same thing. One charges for minutes. One charges for unique callers and explicitly doesn't charge for minutes. One sells call bundles. Two identical businesses can get opposite answers about which is cheapest.

This guide covers the four billing models you'll encounter, what drives the price, the fees that don't show up on a pricing page, and how to run the math for your own phone.

The Four Billing Models

1. Flat monthly fee

The classic version gives you a bucket of minutes, and going over costs a per-minute overage. Predictable, and easy to check against a phone bill you already understand. Our own plans are flat monthly with unlimited minutes:

• Essentials: $197/mo, unlimited minutes
• Growth: $297/mo, unlimited minutes, transfers to your team, missed-call textback
• Pro: $397/mo, unlimited minutes, multi-location and department routing
• Setup (one-time): $1,000 to $2,000 depending on plan

We moved off metered minutes deliberately. A fair-use limit (1,000 to 2,000 minutes a month depending on tier) still sits behind the word "unlimited" to guard against robocall floods, but ordinary businesses run nowhere near it, so in practice the monthly price is the whole price.

Best for: anyone who wants one predictable number on the invoice. Watch for: whether transfers keep billing after the call leaves the AI (ours stop), and, on metered plans, whether unused minutes roll over (usually they don't).

2. Per unique caller

You're billed on how many distinct phone numbers reach the assistant in a month, with minutes uncapped. Goodcall publishes this model: $79, $129, and $249 per agent per month for 100, 250, and 500 unique customers, then $0.50 per additional caller, with no charge for minutes or call count.

Best for: long conversations with a relatively small, repeat customer base. A caller who phones five times costs the same as one who phones once. Watch for: high-churn businesses where nearly every caller is new, and the per-agent structure if you run multiple numbers or locations, since each one is typically billed separately.

3. Per-call bundles

A fixed number of handled calls per month for a flat fee. Smith.ai's AI tier, for example, has published a $97.50/month plan for 30 calls. Simple to reason about, but a 20-second wrong number and a 9-minute booking can count the same.

Best for: low volume with consistent call types. Watch for: what counts as a "call", specifically whether robocalls, hang-ups, and wrong numbers are billed.

4. Pure usage / per minute

No plan, just a per-minute rate. Cheapest at very low volume, and the least predictable at any real volume, since a busy month bills like a busy month.

Best for: seasonal businesses and pilots. Watch for: rounding. Per-second billing and per-minute rounding produce noticeably different invoices when your calls are short.

Same Business, Four Models

Take a salon getting 150 calls a month averaging 3 minutes: 450 minutes, and say 110 of those callers are distinct numbers.

450 minutes · 150 calls · 110 unique callers

• Flat plus minutes (mid tier, 600 included): about $250, under the cap, no overage
• Per unique caller (100 included, $0.50 over): about $84, that is $79 plus 10 extra callers
• Per-call bundle (30 calls, $97.50): doesn't fit, needs five times the bundle
• Pure per-minute at $0.30: about $135, and it moves every month

Now change one variable. Make it a med spa where consultations run 9 minutes and most callers are new: 150 calls is 1,350 minutes and roughly 140 unique callers.

1,350 minutes · 150 calls · 140 unique callers

• Flat plus minutes (top tier, 1,200 included): about $377, that is $350 plus 150 minutes at $0.18
• Per unique caller (100 included, $0.50 over): about $99, minutes don't matter here
• Pure per-minute at $0.30: about $405

That's the whole point: long calls favor per-caller pricing, and lots of short calls from new numbers favor per-minute pricing. Pull your own numbers before you compare rate cards, because the model matters more than the headline price.

What Drives the Price Up

• Call volume and length. The obvious one, and usually the biggest.
• Locations and numbers. Many vendors bill per agent or per phone number. Three locations often means three subscriptions, not one.
• Integrations. Reading live availability out of your booking system and writing appointments back costs more than a system that only takes messages, and saves more.
• Compliance. Healthcare callers mean PHI handling, a signed BAA, retention rules, and access controls. That's real engineering and it's usually priced.
• Phone-system work. Warm transfers, ring groups, IVR replacement, and porting numbers are project work, not a toggle.
• Languages. Multilingual answering is standard on some platforms and an upsell on others.
• Setup depth. Self-serve is $0 and an afternoon of your time. Done-for-you is a fee and someone else's afternoon.

Costs That Aren't on the Pricing Page

• Setup and onboarding fees: $0 to about $2,000 depending on who builds it.
• Number porting, if you move a number rather than forward it. Usually small, sometimes slow.
• Telephony pass-through: some vendors bill carrier minutes separately from the AI.
• SMS: confirmation and reminder texts may be billed per message.
• Transfer time: ask whether billing stops when the call is handed to a human. (Ours stops.)
• Annual lock-in: advertised prices are often the annual-prepay rate; monthly can be 15 to 20% higher.
• Overage rates: the number that decides your bill in a busy month, and the one printed smallest.

Compared With the Alternatives

Monthly cost of answering the phone

• Voicemail: $0, plus every caller who won't leave one
• AI receptionist: $50 to $300 typical
• Live answering service: $100 to $1,000+ typical
• In-house receptionist: about $3,100/mo at the BLS median wage

That last line is $17.90 an hour, the U.S. median for receptionists in May 2024, at 40 hours a week, before payroll taxes, benefits, and the fact that one person doesn't cover 24/7. It isn't an argument against hiring someone; a good front desk does far more than answer calls. It's just the number worth having in front of you.

And the comparison that usually decides it isn't cost against cost. It's cost against what missed calls are already costing you: missed calls per month × average job value × the share you'd actually close. For most service businesses that number is larger than any option on this page.

Is It Worth It at Low Volume?

Sometimes no, and it's worth saying so. If you get a handful of calls a month and answer nearly all of them, the honest answer is voicemail and a same-day callback habit. AI answering starts paying for itself when the calls you're missing are worth more than the subscription, which for a business with a $150 average ticket is roughly two recovered bookings a month.

The way to find out is to count. Most carriers will show you missed calls for the last 30 days in a couple of clicks.
