Choosing an [AI receptionist](/ai-voice-receptionist) is a big decision. The wrong pick costs you time, money, and missed calls. The right one pays for itself fast. Two names come up often in this space: BizRnR and Smith.ai. This post breaks down both so you can make a smart choice.
What Is Smith.ai?
Smith.ai is a virtual receptionist service that has been around since 2015. It offers a mix of live human agents and AI-assisted call handling. Their agents answer calls, take messages, and do some lead intake. Smith.ai is well-known and has a solid reputation in the legal and professional services world.
Here is what Smith.ai is known for:
- Live human receptionists available during business hours
- AI-assisted tools to help those agents work faster
- Monthly plans based on call volume
- Add-on services like outbound calling and CRM integrations
Smith.ai works well for businesses that want a human touch on every call. But that comes at a cost — literally.

Head-to-Head Comparison
Let us look at the key differences between BizRnR and Smith.ai across the areas that matter most to small business owners.
Availability
Smith.ai offers live agents during business hours. After-hours coverage is available but costs more. If a call comes in at 11pm on a Sunday, you may not get the same level of service.
BizRnR answers every call, every hour, every day. There are no shifts, no holidays, and no hold times. Your AI agent is always ready.
Pricing
Smith.ai charges per call or per minute, depending on the plan. Costs can add up quickly as call volume grows. Their entry-level plans start around $285 per month and can climb well above $1,000 per month for busy businesses.
BizRnR offers straightforward pricing with no per-minute surprises. You can check the full breakdown on the [AI receptionist cost page](/pricing/ai-receptionist-cost). The goal is to give small businesses enterprise-level call handling without enterprise-level prices.
Setup Time
Smith.ai requires onboarding calls, intake forms, and time for their team to get up to speed on your business. This can take days or even weeks.
BizRnR deploys in under 45 seconds. You answer a few questions about your business, and your AI agent is live. No waiting. No back-and-forth.
Human vs. AI
This is the core difference. Smith.ai uses human agents supported by AI tools. BizRnR uses AI agents — full stop.
Human agents are great for complex, nuanced conversations. But they get tired, make mistakes, call in sick, and cost more as volume grows. AI agents are consistent. They deliver the same quality on call one and call one thousand.
For most small businesses, the calls coming in are not that complex. Someone wants to book an appointment, get a quote, or ask about hours. An AI agent handles all of that perfectly well.
Lead Qualification
Smith.ai can qualify leads, but the quality depends on the agent who picks up. Training takes time, and turnover at call centers is high.
BizRnR qualifies leads the same way every time. Your AI agent asks the right questions, captures the right information, and routes or books accordingly. No training drift. No bad days.
Industries Served
Smith.ai focuses heavily on legal, financial, and professional services. They do serve other industries, but their tools and workflows are built with those verticals in mind.
BizRnR serves 20+ industries out of the box — dental offices, HVAC companies, plumbers, real estate agents, insurance agencies, auto shops, restaurants, salons, gyms, roofers, cleaning services, landscapers, electricians, pest control, chiropractors, veterinary clinics, accountants, physical therapists, and home inspectors.
The Real Cost of Missed Calls
Here is something worth thinking about before you decide. Businesses lose approximately $126,000 a year to voicemail. That is not a made-up number. That is what happens when calls go unanswered and leads walk away.
And 80% of callers who reach voicemail hang up and call a competitor. Not later. Right then.
If you want to see what missed calls are actually costing your business, use the [missed call ROI calculator](/tools/missed-call-roi). Plug in your numbers. The result is usually eye-opening.
The question is not just which service costs less per month. The question is which service makes you more money by capturing every call.
Who Should Choose Smith.ai?
Smith.ai is a good fit if:
- You run a high-stakes professional services firm (like a law office) where callers expect a human
- You have complex intake processes that need human judgment
- Budget is not a primary concern and you value the human element above all else
- Your call volume is low and predictable
Who Should Choose BizRnR?
BizRnR is a better fit if:
- You are a small business owner who cannot afford to miss a single call
- You want 24/7 coverage without paying for overnight staff
- You need fast setup — like today, not next week
- You want consistent lead qualification every time
- You are in a service-based industry where speed to answer wins the job
- You want to scale call handling without scaling your payroll
For most small businesses — the HVAC company, the dental office, the plumber, the real estate agent — BizRnR is the smarter, faster, and more affordable choice.
What Happens After the Call?
Both platforms do more than just answer calls. But the follow-through matters.
With BizRnR, your AI agent can:
- Book appointments directly into your calendar
- Qualify leads and pass them to your team with full notes
- Send follow-up messages after the call
- Operate across multiple locations if needed
You get a full picture of every call. No more wondering what the receptionist said or whether the lead was captured correctly.
