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.

  • Pure per-minute. You pay $0.09–$0.30 per connected minute, billed in 6-second or 60-second increments. Rounding matters more than you'd think: at 60-second rounding, a 15-second wrong number bills as a full minute. Across 300 calls a month with 40 short calls, that's roughly 30 wasted minutes, or $4.50–$9.00.
  • Subscription with included minutes. A $99/month plan might include 400 minutes ($0.2475 blended), with overage at $0.35. The overage rate is almost always 1.4x to 3x the blended included rate — that spread is the vendor's margin on your growth.
  • Per-resolution or per-booking. Rarer, running $1.50–$6.00 per completed booking. Attractive on paper because it ties cost to outcome, but definitions of "resolution" are usually written by the vendor.
  • 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.

  • 80 calls/month (solo operator): 256 minutes × $0.18 = $46, plus $1.15 for a phone number and ~$2.20 in carrier passthrough. Call it $50/month.
  • 300 calls/month (3–8 truck shop): 960 minutes × $0.18 = $173, plus ~$8 telephony, plus $79/month if the vendor charges a platform fee. $260/month.
  • 1,200 calls/month (multi-location, 4 markets): 3,840 minutes. At volume-tiered $0.12, that's $461, plus ~$33 telephony, plus a $299 platform tier. $793/month.
  • 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.

  • Telephony passthrough. Inbound minutes on a carrier like Twilio run about $0.0085/minute, numbers about $1.15/month, and SMS about $0.0079 per segment. Some vendors bundle it; many bill it at cost-plus.
  • Outbound follow-up. If the agent texts a booking confirmation and calls back on no-answers, you're buying 2–3 extra touches per lead at $0.01–$0.04 each. Small, but it's not zero.
  • Integration and buildout. Connecting to ServiceTitan, Jobber, Housecall Pro, or a GoHighLevel calendar is $500–$2,500 one-time at most agencies, or 6–15 hours of your own time if you do it yourself.
  • Ongoing prompt tuning. Budget 1–3 hours a month for the first quarter. The agent will mishandle things you didn't anticipate — a customer asking about a warranty claim, a vendor calling about a PO — and someone has to write the rules.
  • Number porting and downtime risk. Porting a main business line takes 3–10 business days and is the single most common place a rollout goes sideways.
  • 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.

  • You take fewer than 40 inbound calls a month. At 40 calls you're saving maybe 2.5 hours of interruption per month. The setup time, the tuning, and the porting risk cost more than they return. Forward to your cell and move on.
  • Your calls are long, technical, and consultative. Commercial HVAC design consults, legal intake with liability exposure, medical triage, insurance restoration scoping. Calls that run 12–20 minutes and require judgment are the worst possible fit. The agent will burn $2–$6 in minutes to produce a transcript you have to read anyway.
  • Your customer base skews heavily elderly or non-English-primary. Speech recognition word error rates climb meaningfully on heavy accents, background noise, and speakerphone-in-a-truck audio. If 30% of your callers hang up on a bot, you've bought negative ROI.
  • You have no calendar system. If your scheduling lives in a whiteboard or one dispatcher's head, an AI receptionist has nothing to write to. Fix the calendar first. This is the single most common reason implementations stall.
  • You're regulated in a way that makes recorded AI conversations risky. Two-party consent states, HIPAA-adjacent intake, debt collection. Solvable, but it adds legal review and cost that changes the calculus.
  • You're buying it to cut a person who does more than answer phones. Most small-shop receptionists also do invoicing, permits, warranty claims, and vendor calls. Replacing 30% of a role saves 0% of a salary.
  • The failure modes, named plainly

  • Latency. Good agents respond in 800ms–1.5s. Anything past ~2 seconds and callers start talking over the agent. Test this on a real cell connection, not office wifi.
  • Hallucinated pricing and availability. An agent that invents a $189 diagnostic fee or offers a Tuesday slot you don't have creates a real obligation with a real customer. Constrain the agent to a fixed price list and a live calendar, or don't let it discuss either.
  • The transfer cliff. Expect 15–25% of calls to need a human. If your after-hours transfer target is a phone nobody answers, you've built a more expensive voicemail.
  • Silent degradation. Vendors ship model updates. An agent that worked in March can behave differently in June with no notification. Someone should be listening to 5–10 recorded calls a week, permanently.
  • The 90-day tuning tail. Realistic time-to-good is 6–12 weeks, not the "live in 10 minutes" the demo shows. Budget for a rough first month.
  • AI vs. human answering service vs. hiring

    At 300 calls/month, 960 minutes:

  • AI receptionist: ~$260/month, 24/7, ~1.2s response, handles 75–85% end-to-end.
  • Live answering service: $1.10–$2.50/minute, so $1,056–$2,400/month. Human judgment, but typically message-taking rather than booking, and quality varies by which operator picks up.
  • Part-time in-house receptionist (25 hrs/week at $19/hr): $2,470/month plus burden, covering ~30% of the week.
  • Full-time receptionist: $3,960–$5,600/month loaded, covering ~24% of total hours in a 168-hour week.
  • 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.
