AI phone agent pricing compared (2026)
Last updated: November 9, 2026
AI phone agents bill in at least five different ways: per minute, per call, per unique caller, per location, or through a custom annual contract. Headline prices can't be compared directly. This page groups each vendor's own published pricing by billing unit, and adds details from their terms of service where the pricing page is silent. Taxes, carrier fees, premium voices and negotiated discounts can change what you actually pay. Back to the ranked list of the best AI phone agents.
Per-minute platforms

Note on Phonely: Phonely's pricing page lists two different sets of included minutes. We checked a browser-rendered copy of the page, its Terms of Service and its documentation. None of them settles it. Phonely's docs say your Plan & Billing screen and any order form are the authoritative record, so confirm the allowance with Phonely before you buy.
Per call and per caller
| Product | Unit | Plans |
|---|---|---|
| Smith.ai | Per answered call | Free: 25 calls, then $3/call. Pro: $150 for 75 calls ($2/call). Enterprise: from $500 for 300 calls ($1.67/call) |
| Goodcall | Per unique caller per month | Starter: $79 for 100, then $0.79. Growth: $129 for 500, then $0.26. Scale: $299 for 2,000, then $0.15 |
Per location and enterprise contracts
- Slang.ai: Core from $399 per location, Premium from $599 per location, Enterprise custom. Its Terms of Service say fees are invoiced monthly in advance unless your order form says otherwise. You can cancel within 30 days of your first order form, and order-form terms renew automatically.
- Synthflow: annual enterprise agreement only. No free plan, no trial, no per-minute rate.
- PolyAI platform: custom per-minute pricing through sales, billed per second.
Which billing model is cheapest?
It depends on your calls. Long calls, like bookings and intake, cost less under per-call (Smith.ai) or per-caller (Goodcall) billing. Lots of short calls cost less under per-minute billing. Repeat callers favor Goodcall, because one number counts once per month. If your volume swings from month to month, check how each vendor handles going over: per-minute overage (Phonely), extra callers (Goodcall) or an automatic plan upgrade (Rosie). Model your last month of real calls against each pricing unit before you choose.
