The two terms get used for each other, and vendors do not help. A virtual receptionist is a person, working remotely, answering as your office. An AI receptionist is software that talks. They cost differently, meter differently, and fail differently. Here is the plain version, priced for a real estate office.
Key takeaways
- A virtual receptionist is a human at a service company, billed per call. An AI receptionist is software, billed per minute or per call, answering an unlimited number of calls at once.
- Humans handle the unusual call better. AI handles the fortieth routine call at 9pm exactly like the first.
- Per answered call the gap is roughly ten to one. Smith.ai starts at 300 dollars for 30 calls; AI services start at 25 to 49 dollars a month.
- Most real estate offices end up with both: a person during office hours, AI for overflow, nights, and weekends.
What each one actually is
A virtual receptionist works for an answering company, sits at a desk somewhere else, and answers your line from a script you wrote. They take messages, book appointments if the plan includes it, and transfer calls to you. You are billed per call answered, sometimes per minute of talk time. The receptionist who answers at 9am and the one at 9pm are different people who have both read your script. Phone systems also sell a recorded menu under the same name, which the virtual receptionist explainer untangles.
An AI receptionist is software that answers the call in a natural voice, trained on your website and whatever you add. It asks the questions you gave it, books directly onto your calendar, texts the caller and you, and transfers live when your rules say so. It answers every call in one ring, including twenty at once, at any hour, and every conversation is transcribed. You are billed per minute of conversation, or on some services per call. The automated answering service explainer separates it from the press-one menu that shares the label. Against a salaried person at the desk, the math is in the AI vs human receptionist post.
The differences that matter
| Virtual receptionist (human) | AI receptionist | |
|---|---|---|
| Who answers | A trained person at a service company | Software with a natural voice |
| Simultaneous calls | As many as they staff for | Unlimited |
| Consistency | Depends on who picked up | Identical on every call |
| Unusual calls | Handled with judgment | Handled by your rules, or transferred |
| Setup | Script and onboarding, days | Website plus questions, minutes |
| Billing | Per call, $300 for 30 calls at Smith.ai | Per minute or per call, from $25 to $49 a month |
| Payment on the call | Per-call add-on at Smith.ai | callflo.ai via Stripe; not published elsewhere |
| Transcript of every call | Sometimes, as notes | Yes, verbatim |
When the human is right
- Low volume, high stakes. A boutique brokerage taking 20 calls a month, each one a potential listing, where the caller expects a person.
- Judgment on every call. A probate or estate practice where the caller is upset and the right response is not in any script.
- A brand built on people. Some offices sell the fact that a person answers, and the per-call price is part of the positioning.
The Smith.ai comparison prices this side properly.
When the AI is right
- Volume. A leasing line, a brokerage main line, an investor line after a mail drop. Per-call billing punishes exactly the businesses that need answering most.
- Nights and weekends. AI does not charge more at 2am, and the leasing prospect at 9pm gets a tour booked instead of a message taken.
- Money on the call. An application fee, a deposit, an earnest money hold, collected by card while the caller is on the line.
- Speed to live. Paste a website and hear it answer in minutes, instead of a script review and an onboarding week.
The cost, per answered call
At 100 calls a month, a human service on Smith.ai's 90-call plan plus overage runs about 900 dollars, roughly 9 dollars a call before add-ons. callflo.ai at the same 100 calls of three minutes each is about 215 dollars on Starter with overage, or 697 dollars on VIP with a team running it. Self-serve AI services with more included minutes (Rosie, Dialzara) come in lower still. The receptionist cost breakdown has the full table, including an in-house hire.
