Smith.ai is one of the biggest names in phone answering, and — to its credit — it actually publishes its prices. But there are two separate product lines with two different billing models, and both are metered per call, which makes the real monthly cost harder to predict than the headline numbers suggest. Here's the whole structure in plain English, with the math worked out for a realistic small business, and an honest look at when Smith.ai is worth it. All figures below are Smith.ai's published pricing as of August 2026 — confirm current rates on smith.ai before buying.
Product line 1: the AI Receptionist
Smith.ai's AI product answers calls 24/7 with lead qualification, AI scheduling, call recording and transcription, integrations (Clio, Zapier), analytics, and a "Quality Studio" for testing the agent before it goes live. The published tiers:
- Free — $0/mo: 25 calls included, then $3.00 per additional call.
- Pro — $150/mo: built for roughly 75–300 calls at an effective rate of about $2.00 per call, with overages listed at $2.17–$2.50 per call.
- Enterprise — $500/mo: covers roughly 300–1,000+ calls at an effective rate of about $1.67 per call.
Terms are month-to-month with a 30-day cancellation notice. It's a fair structure — but notice that every tier is fundamentally a per-call price. Your bill is a function of how often your phone rings.
Product line 2: human Virtual Receptionists
Smith.ai's original product is live North American agents answering 24/7 with screening, qualification, and intake. Published plans:
- Starter — $300/mo for 30 calls (that's $10 per call), with overage at $11.50 per call.
- Basic — $810/mo for 90 calls ($9 per call).
- Pro — $2,100/mo for 300 calls ($7 per call).
Per-call add-ons stack on top — $1.50 per appointment booked, $1.00 for Spanish, and similar fees for payments and complex routing. On the plus side: no setup fees, a 10% discount for a 12-month commitment, and a 30-day money-back guarantee on the human plans.
The math: a realistic month
Take a typical busy service business — a contractor, clinic, or firm whose phone rings about 10 times per business day. That's roughly 300 calls a month. At Smith.ai's listed rates:
AI Receptionist: 300 calls puts you at the Enterprise tier — $500/mo (about $1.67 per call).
Human receptionists: 300 calls is the Pro plan — $2,100/mo. If 60 of those callers book appointments, the $1.50 booking add-on adds another $90 → $2,190/mo.
Even a quieter 100-call month outgrows the entry tiers fast: on the AI Free plan, 75 overage calls × $3.00 = $225/mo; on the human Starter plan, 70 overage calls × $11.50 = $805 on top of $300 — so you'd move up to Basic at $810/mo.
The flat alternative: $199/mo. Same bill whether you take 40 calls or 400.
None of that is a hidden fee — it's all published. It's just what per-call billing does: the better your marketing works, the bigger your answering bill gets. Growth is exactly when you don't want your phone system taxing every new customer.
When Smith.ai is worth it
Honestly, there are cases where Smith.ai is the right choice:
- You need live humans on some calls. Smith.ai can escalate from AI to a real agent — pure-AI vendors can't. For legal or medical intake where a caller expects a person, that matters.
- You're a law firm on Clio. The integration depth and legal-intake experience are real strengths.
- You want to trial before spending anything. The $0/25-call free tier is a genuinely low-friction way to hear AI answering on your own line.
- You want a big, established brand with mature analytics and a money-back guarantee on the human plans.
The flat-rate, done-for-you alternative
Cret.ai's AI Voice Receptionist is $199/mo, flat — no per-call meter, no per-minute meter, no booking surcharge. It answers 24/7 in your business's voice, qualifies callers, and books appointments straight into your calendar. And unlike a standalone answering tool, it's bundled into a done-for-you stack: we set it up, tune it, and wire it into a website, CRM, review engine, and follow-up sequences that you own — so the lead it captures actually goes somewhere. (It's included in our Enterprise plan alongside everything else; prices are published on our site, $0 upfront, no contracts.)
We've compared the whole category — Smith.ai, Ruby, Goodcall, Rosie, and more — in our 2026 AI receptionist buyer's guide and on our side-by-side comparison page. And because we're based in Pleasanton, we set this up in person for businesses across the Tri-Valley, from San Ramon to Walnut Creek.
