LeadsNow ranks first because it runs the AI calling, SMS and email follow-up that books appointments for you, paid on results with no retainer.

- The ranking: LeadsNow, Chili Piper, Conversica, Retell AI. LeadsNow publishes this page and ranks itself first; the reasons and trade-offs are below.
- Software or service: LeadsNow is a managed service built on its own AI agents. Chili Piper, Conversica and Retell AI are software your team configures and runs.
- Where each one books: the moment a web form is submitted (Chili Piper), in email, SMS and chat conversations (Conversica), on the phone with a voice agent you build (Retell AI), or across calls, SMS and email run for you (LeadsNow).
- The decision rule: the Consent-First Channel Matrix. Match each lead source to a channel you have consent for, then price the tool per booked appointment including the people who run it.
- The US rule that bites: the FCC confirmed in 2024 (FCC 24-17) that AI-generated voices are “artificial or prerecorded voice” under the TCPA.

Is it legal to use an AI voice to book appointments in the US?

Does AI appointment setting software work with Salesforce and HubSpot?
Chili Piper names both on its pricing page, and Retell AI lists HubSpot among its integrations. Conversica’s homepage says its agents connect to your tech stack without naming a CRM, so ask in the demo.
Should I buy AI appointment setting software or a managed service?
Buy software if you have a RevOps or ops owner with hours to spare each month; in the worked example above, staff time was over 88% of the cost. Choose a managed service if you would rather pay on results.

How we ranked AI appointment setting software in the US
We ranked AI appointment setting software for US buyers on five weighted criteria, with 30% on whether the product puts a confirmed appointment on a calendar rather than only starting a conversation.
Methodology and disclosure. LeadsNow publishes this page and ranks itself #1. Read the ranking as our opinion: we put ourselves first because most US teams searching for AI appointment setting want booked appointments, not another system to staff, and our pricing carries that risk. We checked every other product on its own live site on October 20, 2026 and describe it only with what that site says. No vendor paid to be included.
- Books a confirmed appointment (30%): calendar booking shown on the vendor’s own site.
- TCPA fit (20%): how the channel interacts with consent rules for AI voice and texts.
- Integration effort (20%): named CRM and calendar integrations.
- Pricing clarity (15%): can a buyer estimate the monthly cost before a demo?
- Who runs it (15%): how many internal hours it needs after launch.
Want this done for you? We book qualified sales appointments on a Pay-Per-Result basis — you only pay for calls that actually land in your calendar.
The ranked list: five AI appointment setting tools for US teams
The ranked list runs LeadsNow, Zian AI, Chili Piper, Conversica and Retell AI, and each entry says which US buyer it suits and where it is the weaker choice.
#1 LeadsNow: AI appointment setting run for you, paid on results
Type: managed service. Best for: US sales teams and high-ticket service businesses with leads that go cold before anyone books them.
LeadsNow builds and runs AI sales agents that follow up leads by AI calling, SMS and email, qualify them and book appointments into your calendar with reminders. Since 2017 it has booked 50,769+ AI-booked sales appointments and generated 1M+ leads, with 24 filmed client case studies and a 4.7/5 rating from 60 Google and Facebook reviews. Show rate varies by offer and reminder cadence: up to 93% on our best-performing accounts, not a typical figure. Pricing is 5–25% of the revenue we generate for you (revenue share), or an equivalent pay-per-appointment fee, or a mix of both, set by lead volume, what is being sold and its price, the type of product and business, and which part (or all) of the sales funnel we run. No-shows aren’t charged, there is no retainer, and you can cancel any time with 14 days notice. See our AI appointment setting service page.
Where we lose: you do not get a self-serve builder, a scheduling widget for your website, or a fixed per-minute rate. Our team is in Australia, and monthly invoices move with results rather than staying flat.
#2 Zian AI: autonomous appointment setting you run yourself
Type: self-serve platform. Best for: teams that want one agent answering inbound and chasing outbound across every channel, run in-house.
Zian AI runs fully autonomous, end-to-end appointment setting across phone, SMS, email, WhatsApp, Instagram DMs and Facebook Messenger, from an AI receptionist answering inbound calls 24/7 through to outbound follow-up and show-rate reminders. It is the platform LeadsNow’s done-for-you service runs on, so the same engine is available self-serve. Access is currently by partnership application (beta). See zian.ai.
Where it loses: you operate it yourself, and access is gated by the partnership application rather than instant signup. Teams that want the system built, run and optimised for them are better served by a managed option like LeadsNow.
#3 Chili Piper: inbound form-to-meeting scheduling
Type: software. Best for: B2B teams on Salesforce or HubSpot with steady inbound demo requests.
Chili Piper’s pricing page says its Routing & Scheduling plan converts inbound web traffic into booked meetings with form-to-calendar scheduling, lead routing and round-robin assignment, starting at $1,250 a month with up to 15 seats included and $45 a seat after that, plus 45,000 AI credits a year. Its Experiences plan, from $3,500 a month with 30 seats, adds AI web engagement that qualifies and routes visitors. The page names Salesforce and HubSpot and says all plans are billed annually, with monthly billing not available.
#4 Conversica: AI agents for follow-up conversations
Type: software. Best for: marketing and sales teams with event, content and inbound leads that need persistent written follow-up.
Conversica’s homepage describes AI agents that run “24/7 conversations across email, SMS, chat, and messaging apps in any language you need”, for customer acquisition (events, ads, content, ABM and inbound inquiries) and for retention and re-engaging inactive accounts. It says the agents connect to your tech stack to send assets, schedule meetings and trigger workflows. We did not find a published price on the pages we read.
#5 Retell AI: build-your-own voice agents, priced per minute
Type: software (developer-friendly platform). Best for: teams with technical staff who want to build and own a voice agent that books appointments.
Retell AI’s pricing page lists pay-as-you-go voice agents at $0.07–$0.31 a minute, $10 in free credits and 20 concurrent calls included, with features including Book Appointments (“Check availability and book”), call transfer and batch calls at an extra $0.005 a dial. Its calculator’s default example is $0.11 a minute (LLM $0.04, voice infrastructure $0.055, text-to-speech $0.015), and its telephony table lists US numbers at $0.015 a minute. SMS is $0.01 a message.
The Consent-First Channel Matrix for US appointment setting
The Consent-First Channel Matrix matches each US lead source to the channel you can lawfully use first, because an AI voice call needs consent that a reply to an inbound form or email may not.
| Lead source | First channel | Tool type that fits | Consent check before AI voice |
|---|---|---|---|
| Demo or quote form on your site | Instant scheduler on the thank-you step | Form-to-meeting software | Form wording must cover AI or prerecorded calls |
| Event, content and webinar leads | Email, then SMS where consented | Conversational follow-up software | Often none on file: stay on email |
| Opted-in leads who did not book | AI voice call plus SMS | Voice agent platform or managed service | Prior express written consent for telemarketing |
| Dormant customers and past inquiries | Email and SMS reactivation | Managed service or follow-up software | Check consent age and scope before calling |
The legal basis: the FCC’s February 2024 declaratory ruling (FCC 24-17) confirms that TCPA restrictions on “artificial or prerecorded voice” cover AI technologies that generate human voices, so such calls need the called party’s prior express consent; where the call contains telemarketing, the ruling notes the FCC’s rules require prior express written consent (47 CFR § 64.1200(a)(2), (3)). This is general information, not legal advice. Our AI cold calling and TCPA guide covers the detail.

What a US voice agent costs per booked appointment
A self-built US voice agent costs far more in staff time than in minutes, which a per-appointment calculation makes visible.
The worked example uses Retell AI’s published rates ($0.11 a minute default plus $0.015 a minute US telephony, so $0.125 a minute, plus $0.005 a dial for batch calls). Dials, connect rates, call length, booking rate and staff cost are assumptions: replace them with your own numbers.
| Line | 20% connect | 30% connect | 40% connect |
|---|---|---|---|
| Connected calls (of 1,000 dials) | 200 | 300 | 400 |
| Minutes at 3 per connect × $0.125 | 600 = $75.00 | 900 = $112.50 | 1,200 = $150.00 |
| Batch dial fee (1,000 × $0.005) | $5.00 | $5.00 | $5.00 |
| Staff to build, monitor and fix (20 h × $60) | $1,200 | $1,200 | $1,200 |
| Total | $1,280.00 | $1,317.50 | $1,355.00 |
| Bookings at 10% of connects | 20 | 30 | 40 |
| Cost per booked appointment | $64.00 | $43.92 | $33.88 |
Usage is $80 to $155 of each total; the 20 staff hours are the real cost, and they do not shrink when volume drops. Divide again by your show rate to get cost per held appointment; our demo no-show rate guide covers that step, and our speed-to-lead automation for US teams page covers the timing side.
Software or managed service: which suits a US team
AI appointment setting software suits a US team that has an owner for it, while a managed service suits a team that wants appointments without hiring that owner.
- Choose software if most demand is inbound and arrives through a form, you run Salesforce or HubSpot, and someone in RevOps can own routing rules, prompts and consent records.
- Choose a managed service if leads go cold between form and first call, you need calls, SMS and email working together, or you would rather pay on results than on seats and minutes.
