TL;DR
AI receptionists run $0.09-$0.30 per minute or $50-$500/month flat. Most US service businesses pay $150-$600 all-in. See the full cost math and hidden fees.
→ See how this applies to your business (free 30-min call)An AI receptionist costs $0.09 to $0.30 per minute of talk time, or $50 to $500 per month on a flat subscription. Most US service businesses taking 150–400 inbound calls a month end up paying $150 to $600 all-in, including telephony passthrough and overage. Setup runs $0 to $2,500 depending on how much CRM and scheduling integration you need. That's roughly 1/6th to 1/10th the cost of a full-time human receptionist ($38,000–$52,000 salary plus 25–30% payroll burden), and about half the cost of a traditional live answering service at equal volume.
That's the number. The rest of this page is the math behind it, the line items vendors leave off the pricing page, and the situations where you should not buy one at all.
The three pricing models, and what each actually bills you for
Nearly every vendor in this market uses one of three structures. They are not interchangeable, and picking wrong is where most of the overpayment happens.
The per-minute model wins if your calls are short and your volume is spiky. The subscription wins if your volume is steady and predictable. If you're seasonal — HVAC, roofing, pest control, plumbing — per-minute is usually cheaper across a full year, because you're not paying for July capacity in February.
What a real monthly bill looks like at three call volumes
Assume an average inbound service call of 3.2 minutes, which is typical for a booking-and-qualify conversation with a residential customer.
At that top tier you're at roughly $0.66 per call answered. A human answering service billing $1.40/minute on the same traffic would run $5,376/month.
The costs nobody puts on the pricing page
This is where the quoted $99 becomes a real $310.
Fully loaded, a mid-sized service business should plan on $3,600–$9,600 per year, not the $1,200 the sticker implies.
The number that actually matters: cost per booked job
Cost per minute is a vanity metric. What you want is cost per booked job.
Take the 300-call example at $260/month. If the agent books 34% of inbound calls — a realistic figure for a well-configured agent handling residential service intake — that's 102 booked jobs, or $2.55 per booking. If your average ticket is $420 with a 45% gross margin, each booking contributes $189. The math is not close.
Now flip it. If the agent books 9% because it can't quote pricing, can't access your calendar, and transfers half the calls anyway, you're at $28.89 per booking and you've added a layer of friction customers can hear. Same product, same price, completely different verdict. The variable is configuration quality, not the vendor's per-minute rate.
The cheapest AI receptionist is the one that books jobs. A $99 agent that converts 9% of calls is more expensive than a $500 agent that converts 34%.

When an AI receptionist is a waste of money
This is the section most vendor pages skip. Do not buy one if any of the following describe you.
The failure modes, named plainly
AI vs. human answering service vs. hiring
At 300 calls/month, 960 minutes:
The honest comparison isn't AI vs. human. It's AI vs. the voicemail you have now — because 62% of small service businesses aren't staffing the phone at 7pm anyway, and an unanswered call on a $600 job is a $600 loss, not a $0.58 savings.
How to buy without overpaying
Ask every vendor these five things in writing: billing increment (6-second or 60-second), overage rate, whether telephony is bundled or passthrough, what "included minutes" counts (connected time only, or ring time too), and the contract term. Month-to-month should be available; a 12-month lock at this price point is a red flag, not a discount.
Then pilot on a single overflow line for 30 days before porting your main number. Route calls that currently go to voicemail. Downside is capped at zero, and you'll get 60–100 real recorded conversations to judge from — which is worth more than any demo.
If you'd rather not assemble prompts, telephony, and CRM plumbing yourself, that's what a build-and-manage engagement covers; see what's included and what it costs and our voice AI implementation work for how the pieces fit together.
Budget line for planning: $50/month solo, $250–$400/month for a 3–8 truck shop, $700–$1,100/month multi-location, plus $500–$2,500 one-time setup and 90 days of patience.
Frequently Asked Questions
How much does an AI receptionist cost per month?
Most US service businesses pay $150 to $600 per month all-in. Flat subscriptions range from $50 to $500, while usage-based plans bill $0.09 to $0.30 per minute of talk time. At 150 to 400 inbound calls monthly, telephony passthrough and overage charges push the total toward the upper end.
Is an AI receptionist cheaper than a human receptionist?
Yes. A full-time human receptionist costs $38,000 to $52,000 in salary plus 25 to 30 percent payroll burden, roughly $48,000 to $68,000 annually. An AI receptionist at $150 to $600 per month runs about one-sixth to one-tenth of that, and roughly half a traditional live answering service at equal volume.
What hidden fees do AI receptionist vendors charge?
The pricing page rarely includes telephony passthrough, the per-minute carrier cost of the phone number and call legs, plus overage rates once you exceed bundled minutes. Also check whether billing counts spam and wrong-number calls, charges per extra phone number, or requires an annual commitment for the advertised rate.
How much does AI receptionist setup cost?
Setup runs $0 to $2,500. Vendors with self-serve onboarding and a simple call script often charge nothing. Costs rise when you need CRM and scheduling integrations, custom call routing, multi-location handling, or migration of existing phone numbers. Expect the high end if a vendor builds and tests the workflow for you.
