Verdict: the lowest plan price for an AI receptionist is rarely the lowest bill, because the overage charge per extra call decides what a clinic actually pays.
TL;DR: AI receptionist pricing is usually sold as a monthly plan with a set number of calls or minutes. Once you go past that allowance, the human-backed plans we checked charge about $9.50 to $10.50 per extra call. Spam calls count toward the same allowance. Compare the cost per call you will really use, not the headline plan price.

Pick a flat-rate plan if your call volume is steady and you want one fixed bill every month. Dupple's 2026 review lists Goodcall at $79 a month for unlimited minutes.
Pick a human-backed plan if a missed or mishandled call can cost you a patient. You will pay more per call, but a person can step in when the AI can't.
Pick a low-cost per-minute plan if your volume is small and a 60-minute cap is enough. Dupple lists Dialzara from $29 a month for 60 minutes.
What does an AI receptionist really cost per call?
An AI receptionist's real cost per call is the plan price divided by the calls you actually use, plus any overage. For Smith.ai's Starter plan, that is $292.50 divided by 30 calls, or $9.75 per call, if you use every call included. Most clinics will not hit that number exactly, so the real figure is higher.
The effective price falls as the plan gets bigger. Using the figures from the sources below, the per-call cost drops from about $9.75 on Starter to about $8.88 on Basic (60 calls at $532.50) and about $8.13 on Pro (120 calls at $975). Bigger plans look cheaper per call only if you fill them.
The sources disagree on these numbers. One guide lists Starter at $292.50, while a Toolradar page checked in September 2026 lists $300 for the same 30 calls. Basic ranges from $532.50 to $585 across reviews. Treat every figure here as a starting point and confirm it on the vendor's pricing page before you commit.
How do overage fees change the real price?
Overage fees are the charge for every call above your plan's allowance, and they are where most clinic budgets break. Across the reviews we checked, Smith.ai's extra calls cost about $9.75 to $10.50 each on the Starter plan.
Here is the math on a busy month. A Starter plan with 30 included calls costs $292.50. If the clinic takes 40 calls, the 10 extra calls add $105 at $10.50 each, bringing the bill to $397.50. That is $9.94 per call, slightly more than the plan's headline rate, and the gap grows as volume rises.
Add-ons can push the number higher still. One review lists appointment booking as an extra $1.50 per call, so a booked call costs more than a simple answered call.

Does spam call volume raise your bill?
Yes. Spam and robo-calls count toward your call allowance on the plans we checked, so unwanted traffic can push you into overage. One G2 reviewer described AI robo-scam calls that drove up call volume, and support recommended a higher tier to avoid overage charges.
This is the mistake most clinic owners miss. A plan that looks affordable on paper can turn expensive in a month when a marketing robo-call campaign or a wave of solicitors hits your number. Ask the vendor whether unsolicited sales calls are filtered out before they count. One review says spam is not charged when caller ID is passed through, so check whether your number supports that setting.
Before you sign, ask for one number: the monthly bill in a month with 20 percent more calls than you expect. If the vendor cannot give you that figure, you are buying a guess.
How should a clinic compare AI receptionist pricing?
Compare AI receptionist pricing on the cost per call you will actually pay, not on the sticker price. Put every plan into the same table with the same call volume, then add the overage and any booking add-on. The cheapest plan on paper often becomes the most expensive plan once real volume arrives.
The table below puts the main options side by side. Prices and limits change often, so verify each one on the official pricing page before deciding.
| Option | Monthly price | Included calls or minutes | Overage | Best for |
|---|---|---|---|---|
| Smith.ai Starter | $292.50 to $300 | 30 calls | About $9.75 to $10.50 per call | Low-volume clinics that want a human backup |
| Smith.ai Basic | $532.50 to $585 | 60 calls | About $9.50 per call | Mid-volume clinics with booking needs |
| Smith.ai Pro | $975 to $1,170 | 120 calls | Check the vendor page | High-volume practices |
| Goodcall | $79 (per Dupple's 2026 review) | Unlimited minutes | None listed | Predictable, flat monthly budgets |
| Dialzara | From $29 (per Dupple's 2026 review) | 60 minutes | Per-minute, see our Dialzara review | Small practices testing AI reception |

Smith.ai Starter — $292.50 to $300/mo
Best for: a small clinic that wants a human to back up the AI on tricky calls.
What's included:
- 30 calls per month
- Human-backed call handling, per the vendor's description
- Overage of roughly $9.75 to $10.50 per extra call
Watch out for: a busy month or a spam wave can push you past 30 calls quickly.
Smith.ai Basic — $532.50 to $585/mo
Best for: a mid-volume practice that books appointments during calls.
What's included:
- 60 calls per month
- Overage of about $9.50 per extra call on one review's figures
- Appointment booking, which one review lists as an extra $1.50 per call
Watch out for: the booking add-on raises the per-call cost on every booked call.
Goodcall — $79/mo, unlimited minutes
Best for: a clinic that wants one predictable bill every month.
What's included:
- Unlimited minutes, per Dupple's 2026 review
- A flat monthly fee rather than per-call overage
Watch out for: check the vendor's terms for any usage or fair-use limits before you rely on "unlimited."
Pick the plan whose cost per call stays flat as your volume changes. For most clinics, that means a flat or high-allowance plan, because overage is the expensive part of the bill. A smaller plan only makes sense if your volume is genuinely low and you can absorb occasional overage.
| If you want... | Pick this | Why |
|---|---|---|
| One fixed monthly bill | Goodcall-style flat plan | No per-call overage to forecast |
| A human to catch hard calls | Smith.ai human-backed plan | You accept a higher cost per call for a person on the line |
| The lowest starting price | Dialzara entry plan | Low monthly cost, but the 60-minute cap needs watching |
| Lower cost per call at volume | Smith.ai Pro | Per-call cost falls to about $8.13 if you use all 120 calls |
| Protection against spam inflating bills | A flat plan with filtering | Unwanted calls cannot push you into overage |
Bottom Line
The AI receptionist price that matters is the cost per call you actually pay, after overage and spam are counted. Human-backed plans like Smith.ai's Starter cost roughly $9.75 to $10.50 per call once you pass the allowance. A flat plan such as Goodcall's $79 tier, as Dupple reports it, removes that risk if its terms match your volume. Pick the plan whose bill you can predict, and verify every figure on the vendor's official page first.

Frequently asked questions
Is the cheapest AI receptionist the best value for a clinic?
No. The cheapest plan often has the lowest allowance, so a busy month pushes it into overage. Compare the cost per call you will actually use, including overage and any booking add-on.
How much does Smith.ai cost per extra call?
Across the reviews we checked, Smith.ai's overage on the Starter plan is about $9.75 to $10.50 per call. Confirm the current figure on Smith.ai's pricing page before you sign, because sources disagree.
Do spam calls count toward my plan's call limit?
On the plans we checked, yes. A G2 reviewer described AI robo-scam calls that raised their call volume and pushed them toward overage. Ask the vendor how unsolicited calls are filtered before they are counted.
Is Goodcall really unlimited?
Dupple's 2026 review lists Goodcall at $79 a month for unlimited minutes. Check the vendor's terms for any fair-use limit, because "unlimited" can carry conditions.
Can an AI receptionist book appointments during the call?
Some plans can, and one review lists booking as an extra $1.50 per call on Smith.ai. Test the booking flow with a real calendar before you rely on it, and confirm the add-on price on the vendor's page.
What should I ask a vendor before I sign?
Ask for the monthly bill in a month with 20 percent more calls than you expect. Ask how spam calls are counted, what the overage rate is, and whether booking costs extra. If the vendor cannot answer these in writing, the pricing is not clear enough to commit to.
