Best AI receptionist for small business: 9 real options compared
Short answer: The best AI receptionist for most small businesses is a packaged product built into software you may already use, Housecall Pro's CSR AI or Jobber's Receptionist add-on at $29 a month if you're already on one of those field service platforms, or Calilio if you want a dedicated business phone system with AI call handling, starting at $15 a month per user, as of October 2026. If you need something more customized than any packaged product offers, Vapi and Retell let a developer build a voice agent from scratch, and Smith.ai is worth considering if you'd rather have real people answer than an AI voice at all.
You're comparing AI receptionist options for your small business and want real prices and real differences, not a vendor's own ranking of itself.
I'm Ranjit, and I run Blur Studio: 15+ years building software, 120 apps taken live, and clients who have gone on to raise $10M+. I build AI systems and processes that help businesses do a lot more with a lot less time. I also work differently from most of what else is out there, more on that further down this page. Say hello.

Two different categories, and why that matters
"AI receptionist" covers two genuinely different kinds of product. Dedicated products are ready to use: you sign up, configure some settings, and it answers calls within a day. Build-your-own platforms like Vapi and Retell give a developer the pieces to assemble a custom voice agent, more flexible, but someone has to actually build and maintain it. Most small businesses should start with a dedicated product and only move to build-your-own once a packaged option genuinely can't do what they need.
Nine options, compared on October 2026 pricing
| Option | What it is | Price | Best for |
|---|---|---|---|
| Calilio | Business phone system (VoIP) with an AI voice agent built in | $15/month per user (Standard), 10 free AI minutes/user/month, then $0.25/min | A small team that wants a phone system and AI call handling in one subscription |
| Housecall Pro CSR AI | AI call answering add-on inside the Housecall Pro field service platform | Base plans $59 to $299/month; CSR AI's specific add-on price isn't published, contact Housecall Pro directly | A trades business already running Housecall Pro for scheduling and invoicing |
| Jobber Receptionist | AI call and text answering add-on inside Jobber | $29/month add-on, included in the Plus plan | A trades business already on Jobber that wants calls booked straight into existing jobs |
| ServiceTitan AI Virtual Agent | AI call handling feature inside ServiceTitan, aimed at larger shops | Available on ServiceTitan's Pro tier; ServiceTitan doesn't publish flat pricing, it's quote-based | A larger HVAC, plumbing or electrical shop already running ServiceTitan |
| KrispCall | Business phone system (VoIP) with AI call features | Pricing page returned an access error when I checked it live, confirm current plans directly on krispcall.com | Teams already evaluating KrispCall for VoIP who also want AI call handling |
| ElevenLabs (voice agent platform) | General-purpose conversational AI platform, not a packaged receptionist product | $5/month (Starter) and up, usage draws from your plan's credit pool | A business that wants more control over the agent's voice and script than a packaged product allows |
| Vapi | Developer platform for building a custom voice agent from scratch | Free to start with $5 in credits; Core plan $29/month; pass-through per-minute model costs on top | A business with a developer and a call flow too specific for any packaged product |
| Retell AI | Developer platform for building a custom voice agent, with pre-built templates | $10 in free credits; per-minute cost of $0.07 to $0.31 depending on model and features; $2/month per phone number | A developer who wants templates to start from rather than building fully from scratch |
| Smith.ai | Human-staffed virtual receptionist service, with AI-first and hybrid options also offered | $300/month for 30 calls (Starter), up to $2,100/month for 300 calls (Pro), overage $8.50 to $11.50 per call | A business that wants a real person answering, not a synthetic voice, and is willing to pay more for it |
I live-checked pricing directly on Calilio's, Housecall Pro's, Jobber's, ServiceTitan's, Vapi's, Retell's and Smith.ai's own sites for this guide. KrispCall's pricing page returned an access error on every attempt, so I'm not stating a number there, confirm it yourself before buying.
Can you combine more than one of these?
Yes, and some businesses genuinely should. A trades business on Jobber might use Jobber's Receptionist for its main scheduling line while also keeping Smith.ai on retainer specifically for a separate, higher-touch sales or estate-size-job line, where a human's judgment on a large, consultative sale is worth the extra cost. Running two systems does add complexity, you need to be clear about which number routes where and why, but it lets you apply the cheaper AI option to the bulk of routine calls while reserving the more expensive human option for the specific calls where it earns its keep.
Picking by business type
- Already running Jobber or Housecall Pro: Use the built-in add-on (Jobber Receptionist or CSR AI) first. Calls land directly in the system you already schedule jobs from, which a separate third-party tool won't do as cleanly. Trades owners can also read about AI receptionists for plumbers, HVAC and electricians.
- Not on a field service platform, want something simple fast: Calilio, since it's a complete phone system with AI handling bundled at a clear, published price. KrispCall's plans are worth comparing against it directly once its pricing page is accessible for you.
- Want full control over the script, voice and logic: Vapi or Retell, if you have a developer or are willing to hire one for the setup. Vapi, Retell and ElevenLabs agents compared helps you pick between the build-your-own routes.
- Want a real person, not a synthetic voice, but still want 24/7 coverage: Smith.ai, at a meaningfully higher price point than any AI-only option. See AI versus human receptionist on cost and quality before you decide.
Questions worth asking any vendor before signing
- What happens past the included minutes or calls? Every option here has an overage structure, whether it's per-minute, per-call, or a flat upgrade tier. Model your actual expected volume against it, not just the headline entry price.
- Does it book directly into the system you already use? A tool that answers the call but dumps the result into a separate inbox you have to manually check loses most of its value. This is where the platform-native options (Jobber, Housecall Pro, ServiceTitan) have a real structural advantage over a standalone phone system.
- What's the actual setup time? A packaged add-on like Jobber's Receptionist can often be configured in under an hour. A custom build on Vapi or Retell realistically takes days to weeks depending on complexity. Factor this into your decision, not just the monthly price.
- Can you test it before committing to a contract? Smith.ai offers a 30-day money-back guarantee with no long-term contract. Vapi and Retell both offer free credits to test before paying. Confirm what your specific option allows before signing anything longer-term.
The most common mistake in picking from this list
The most common mistake is picking based on the lowest headline price without modeling actual expected call volume against each option's overage structure. A tool that looks cheapest at a glance can end up costing more than a pricier-looking option once your real monthly call minutes are run through its specific per-minute or per-call overage rate. Before committing to any option on this list, write down your rough expected monthly call volume and run it through each candidate's actual pricing structure, not just its advertised entry price.
How does Blur Studio approach AI receptionists?
If you're already on Jobber, Housecall Pro or ServiceTitan, I'll usually point you to the built-in AI receptionist feature first rather than selling you a separate system, it's genuinely the better fit in most of those cases. Where I get involved is when your call handling needs something none of these products do out of the box, a specific routing rule, an integration with a system none of them connect to, or a scale of custom logic that justifies building on Vapi or Retell with someone maintaining it.
Questions people ask
What's the cheapest AI receptionist option here?
Calilio and Vapi both have low entry costs, Calilio at $15 a month per user with free included AI minutes, Vapi free to start with usage-based pass-through pricing after that. The right comparison depends on your actual call volume, not just the sticker price.
Is Jobber's Receptionist the same thing as ServiceTitan's AI Virtual Agent?
They solve a similar problem but aren't the same product. Jobber's Receptionist is a $29-a-month add-on built for smaller teams already on Jobber. ServiceTitan's AI Virtual Agent is positioned for larger shops already paying for ServiceTitan's Pro tier, at a quote-based price.
Do I need a developer to use any of these?
Not for Calilio, Housecall Pro's CSR AI, Jobber's Receptionist, ServiceTitan's AI Virtual Agent or Smith.ai, those are ready to configure. Vapi and Retell are built for developers to assemble a custom agent.
Can I switch from a human answering service to an AI one later?
Yes, most businesses can run both side by side during a transition, keeping Smith.ai or a similar human service for complex calls while routing simple, repetitive calls to an AI option first.
Roughly what does a custom build cost?
As a broad reference, fixes and finishes start at around $1,500, and new builds start higher, always a fixed price agreed in writing before I start, never an hourly rate. My AI app cost guide explains what actually drives a quote up or down.
Is my project too small for this?
No. Most of the owners I work with have no tech team at all, that is the whole point. If the smarter move is a cheap software subscription instead of custom software, I will tell you that on the first call, even though it means I do not get paid.
