Best AI receptionists for small business
A small business doesn't need enterprise voice infrastructure. It needs something that answers, books, and knows when to hand off.
Retell AI is the best starting point for a small business with some technical comfort: its pricing is itemized rather than bundled, and $10 of free credit is enough to build and test a real call flow before paying anything. A business with zero appetite for setup should go straight to a human-backed service like Ruby instead.
The short answer
- Retell AI itemizes its per-minute costs ($0.055/min voice, $0.015/min text-to-speech, add-ons for knowledge base and PII removal) rather than bundling them, which makes it easier for a small business to estimate real monthly cost before committing.
- Vapi is the most flexible and the most work: a $0.05/min platform fee, then you choose and pay for your own model, voice and telephony, which usually pushes the real cost to $0.07-$0.25/min.
- Bland AI's $299/month Build plan platform fee only pays off once call volume is high enough to use it; at low volume, pure usage-based pricing on Vapi or Retell AI is cheaper.
AI receptionist options for a small business
| Platform | Starting price | Setup effort | Human handoff | Best for | Not for |
|---|---|---|---|---|---|
| Retell AI | $0.07-$0.31/min all-in, $10 free credit | Moderate, dashboard-based agent builder | Configurable transfer rules | A small business willing to configure a call flow once | A business with no time to set anything up |
| Vapi | $0.05/min platform fee + your own model/voice/telephony | High, most assembly required | Configurable, built by you | A technical owner or a hired developer | Anyone who wants a receptionist working same-day |
| Bland AI | $299/mo platform fee + $0.12/min (Build plan) | Moderate, tiered dashboard plans | Configurable transfer rules | Higher call volume where the flat fee pays off | Low call volume, the fee dominates the cost |
| Ruby | $250/mo for 50 minutes | None, live in days | Default, a real person, not a fallback | A business that wants zero setup and a human by default | Cost-sensitive businesses at real call volume |

What each one actually gets you
Retell AI
Component pricing that's visible before you commit, plus a meaningful free-credit runway to test a real setup. Its knowledge-base add-on ($8/month per knowledge base, first 10 free) is a reasonable way to give the receptionist your hours, services and FAQs without a full integration project. Not for: a business that wants a finished product with nothing to configure.
Vapi
The most control and the most assembly. You choose the model, the voice provider and the telephony layer, which means the ceiling on what you can build is high, but so is the floor of effort to get something live. Not for: a small business without in-house technical capacity or budget to hire one.
Bland AI
A dashboard-first product with tiered plans rather than raw usage pricing, which makes budgeting more predictable once volume justifies the $299/month platform fee. Daily call and concurrency caps (2,000 calls/day, 50 concurrent on Build) are generous for most small businesses. Not for: testing at low volume, where the fee outweighs the benefit.
Ruby
The only entry here that is not an AI platform: a real receptionist answers the phone, with AI enhancements layered in at no extra charge per Ruby's own pricing page. The tradeoff is cost per minute, which stays roughly $5 even on the largest plan. Not for: anyone optimizing for cost at scale rather than reliability with zero setup.
When none of these is the answer
A business taking under a dozen calls a week does not need a receptionist product at all. Voicemail with a habit of calling back the same day covers that volume, and every option on this page costs more than the value it returns at that scale.
If the goal is a receptionist that also books into your CRM and pipeline automatically, none of the platforms above do that natively; you would be wiring a webhook or API call yourself. SalesCrew is not included in the ranking above because its own inbound phone and AI receptionist features are on the roadmap, not shipped; today it runs outbound calls through Vapi as one channel among several, but it is not yet a receptionist product you could put in front of a live line.
Questions
- Do I need a developer to set up an AI receptionist?
- For Vapi and Retell AI, yes in most cases, or at least someone comfortable configuring a call flow, a knowledge base and a transfer rule. Bland AI's tiered plans and dashboard reduce that somewhat. A human-backed service like Ruby needs no technical setup at all.
- How much does an AI receptionist cost per month for a small business?
- For low call volume, a platform fee model like Bland AI's $299/month Build plan can cost more than pure usage-based pricing at low volume. A rough small-business estimate on Vapi or Retell AI, at a few hundred minutes a month and $0.10-$0.20/min all-in, lands around $30-$100 a month before any platform fee, though actual cost depends heavily on which model and voice you choose.
- Can an AI receptionist route calls to different people?
- Routing and transfer rules are configurable on the AI platforms covered here, but they have to be set up per business; it is not automatic. Confirm the transfer logic works the way you expect before going live, not after the first real caller hits it.
- Is a human receptionist still better for a small business?
- For businesses where every call is high-stakes, such as intake for a medical or legal practice, a trained human still handles edge cases an AI model cannot. For call volume that is mostly routine, appointment requests, hours, simple qualifying, an AI receptionist configured well is usually good enough and costs less per minute at any real volume.
