1. RunDesk AI
Our pick"Your phone rings. We answer. And then we handle what comes next."
RunDesk AI is positioned as an AI employee, not just an answering service. It answers calls 24/7, books appointments, takes messages — and on the Pro and Business plans, it does post-call actions: SMS follow-ups, invoicing, logging to Google Sheets, and a daily summary digest. Designed for small service businesses where the owner is on a job and needs more than "someone picked up."
What it does well
- Learns from your website automatically on signup
- SMS follow-ups to customers at $149 (not a paid add-on)
- Native Google Sheets integration at $299
- Invoicing & payment collection on Business tier
- Daily summary email of what happened yesterday
- Under 60-second setup
What it doesn't do
- No bilingual Spanish support yet (English only)
- No warm call transfer yet
- Newer brand — fewer public reviews than competitors
- No human fallback option for complex calls
2. Rosie
AI answering"10x better than voicemail. 10x cheaper than a traditional answering service."
Rosie is the closest direct competitor to RunDesk AI — same pricing, same target market, similar feature set. Where Rosie stands out is bilingual English/Spanish on every plan, warm call transfer on the Scale tier, and a longer track record with published customer testimonials.
What it does well
- Bilingual English/Spanish on every plan
- Warm call transfer at $149
- Smart spam detection
- Solid set of native booking integrations (Google Calendar, Calendly, Acuity, Appointlet)
What it doesn't do
- Website texting widget is a $50/mo add-on
- No native CRM integrations — Jobber/HCP require Zapier
- No invoicing or payment collection
- Message texting costs extra above base plan minutes
3. Smith.ai
AI + human"AI-powered with human backup."
Smith.ai is a hybrid — AI handles the first part of every call, and human receptionists take over when needed. If AI gets stuck or the caller requests a human, a real person joins. Pricing is per-call rather than per-minute on some plans, which can be more or less expensive depending on call patterns.
What it does well
- Human fallback for complex or emotional calls
- 24/7 coverage
- Qualifies leads before passing to sales
- Popular with law firms
What it doesn't do
- Typically 3–6x more expensive than pure AI
- Per-call pricing can be unpredictable for high-volume businesses
- Humans are US-based but still "outsourced" — may not know your business details
- More setup required than plug-and-play AI
4. Ruby Receptionists
Human receptionist"A real person every time."
Ruby is the premium option: real human receptionists, US-based, who answer your phone under your business name. No AI. If "a human voice" is non-negotiable for your brand — typical for established law firms, dentists, and high-end service businesses — Ruby is the reference.
What it does well
- Every call answered by a real person
- Receptionists trained on your business
- Warm, natural conversations — no AI quirks
- Strong legal-industry specialization
What it doesn't do
- Starts at $349/mo — 7x the cost of AI
- Charged per call, not per minute — 50-call plan runs out fast
- No 24/7 coverage on lower plans
- Receptionists aren't in your office — context is limited
5. Voicemail
Doing nothing"Leave a message and we'll call you back."
The default. It's free. But research consistently finds that about 62% of callers hang up rather than leave a voicemail, and most who do leave a message will have called your competitor within the hour. For a small service business, voicemail isn't "nothing" — it's a revenue leak.
What it does well
- Free
- Built into every phone
- No setup required
What it doesn't do
- ~62% of callers hang up without leaving a message
- Those who do leave messages often call your competitor next
- No triage, no booking, no context
- You still have to call them back — time you don't have on a job
How to pick
Most small service businesses come down to a few questions:
- Do I need bilingual support? If yes → Rosie.
- Do I want the AI to handle follow-ups, invoicing, and data logging? If yes → RunDesk AI.
- Do I need a human voice for every call? If yes → Ruby.
- Is the occasional complex call worth 3–6x the price? If yes → Smith.ai.
- Am I OK losing 62% of inbound callers? If yes → voicemail.
If you're reading this page, you've already answered the last one: you're not OK with it.
FAQ
What is the best AI receptionist for small business?
It depends on what you value. RunDesk AI fits small service businesses that want automation beyond the call itself — SMS follow-ups, invoicing, Sheets logging. Rosie fits businesses with Spanish-speaking callers. Both cost $49/mo to start.
How much does an AI receptionist cost?
Most start at $49/mo for about 250 minutes. Mid-tier plans with appointment booking run $149/mo. Top tiers with advanced features hit $299/mo. Human receptionist services start around $349/mo.
Is an AI receptionist as good as a human?
For ~80% of calls — basic questions, message taking, appointment booking — modern AI handles them indistinguishably from a human receptionist and faster. For emotionally complex calls, legal intake with nuance, or callers who are upset, a human is still better. Hybrid services like Smith.ai bridge both.
Can AI receptionists book appointments on my calendar?
Yes, on mid-tier plans ($149/mo) at both RunDesk AI and Rosie. The AI reads your availability and books directly into Google Calendar, Calendly, or Acuity.
Do I get to keep my existing phone number?
Yes. All the services above give you a new AI number. You forward your existing business number to it. Your customers never see the change.
How fast can I get set up?
RunDesk AI advertises under 60 seconds. Rosie advertises quick setup but reviews describe 30–60 minutes to tune quality. Smith.ai and Ruby require onboarding calls — expect a few days before you're live.
