Smith.ai is a solid AI receptionist with a real strength: live humans as backup. Its per-call pricing is also the reason people look for alternatives once call volume grows. Here is the honest comparison, with the math at three volumes.
New to the topic? Start with the complete AI receptionist guide for small business: what it does, what it costs, and how it compares.
Smith.ai's AI Receptionist answers calls with AI and, on its paid plans, can hand a complex call to a live, North America-based receptionist. That human backup is the feature competitors mostly do not offer, and for some businesses it is the deciding factor: a law firm intake, a medical office, a caller who simply refuses to talk to a machine.
It also has a free plan with 25 calls a month, which is a genuinely useful way to try AI answering with no commitment.
The reason is almost always pricing structure, not quality. Smith.ai bills per call: Pro starts at $150 a month for 75 calls, Enterprise from $500, and extra calls cost roughly $2.17 to $3.00 each. Per-call pricing is predictable when you get a few long calls, and expensive when you get many short ones: a two-minute "are you open on Saturday" call costs the same as a twenty-minute intake.
Most AI phone agents bill by included minutes instead. At the call lengths a small business actually sees (two to four minutes), minutes are usually the cheaper unit.
Assumptions: average answered call of three minutes; Smith.ai Pro at $150 for 75 calls and $2.50 per extra call (the middle of its published range); Striveloom tiers as published: Lite $49 for 300 minutes, Starter $99 for 500 minutes, Pro $299 for 2,000 minutes.
| Monthly calls | Minutes (at 3 min) | Smith.ai Pro | Striveloom |
|---|---|---|---|
| 60 | 180 | $150 (within 75 calls) | $49 (Lite) |
| 150 | 450 | $150 + 75 × $2.50 = $337.50 | $99 (Starter) |
| 400 | 1,200 | $150 + 325 × $2.50 = $962.50 | $299 (Pro) |
If your calls are long (ten minutes or more), the gap narrows; if they are short, it widens. Run the numbers with your own average call length, which your current phone bill shows.
Entry prices are each vendor's published figure at the time of writing; the best AI receptionist software comparison keeps the full table with sources.
Minute-based plans from $49 (300 minutes) to $999 (5,000 minutes), inbound and outbound, booking into your real calendar, lead capture to your CRM, transcripts, and transfer of the live call to your phone when the caller asks for a person. There is no third-party human receptionist; the human backup is you or your team, which is what most small businesses prefer anyway. Per-call and monthly spend caps are on every plan.
Best for: businesses that want 24/7 coverage, bookings and lead follow-up at a flat price, and that are comfortable being the escalation point.
The natural pick if you already use RingCentral phones: AI answering inside the same system and bill, from $49 standalone or $39 as a RingEX add-on, 100 included minutes.
Best for: existing RingCentral customers with modest volume.
Fully-AI receptionists with entry plans between $29 and $99 a month, differing in included allowance and billing unit (minutes, or unique callers in Goodcall's case). Worth a look if you want the lowest entry price and have light volume.
The AI phone answering service guide covers the setup in an afternoon, and the AI receptionist cost guide has the cost model at more volumes. To try the minute-based option, the AI Phone Agent page has the live tiers and a 7-day trial.
It depends on why you are switching. For a flat monthly price with booking, outbound callbacks and spend caps, a minute-based AI phone agent such as Striveloom (from $49 for 300 minutes). For existing RingCentral customers, RingCentral AIR. If you need live human backup, Smith.ai remains the stronger fit.
Per call: a free plan with 25 calls a month, Pro from $150 a month for 75 calls, Enterprise from $500, and about $2.17 to $3.00 per additional call, according to its public pricing page.
For the two-to-four-minute calls most small businesses receive, per-minute plans are usually cheaper; per-call pricing is better when calls are long. Multiply your monthly calls by your average call length and compare the two.
No. When a caller asks for a person, the live call is transferred to your own phone with the transcript already in your dashboard. The escalation point is your team rather than a third-party call center.
Yes. Forward your line to the new agent only after hours or only when busy during the trial, keep Smith.ai during the day, and compare the transcripts and bookings for a week.
