Is an AI receptionist worth it? For some businesses it clearly is, and for some it clearly is not, and the difference shows up in three numbers you can count yourself in two weeks: how many calls go unanswered, how many of those were new business, and what a new customer is worth to you.
We set up AI receptionists for a living, so read this with that in mind. We would still rather you buy one because your own numbers say so than because a sales page did. Nothing below uses industry averages, because an average from someone else's business tells you little about yours. Every blank in the worksheet is yours to fill in.
The two-week worksheet
Print this or copy it into a notebook. Fill it in from your phone records and your own judgment, not from estimates you read online.
- Pull two weeks of calls. Your phone carrier's app, your business phone system or your monthly bill usually shows every incoming call, including the ones nobody answered.
- Count the calls nobody picked up. Include calls that rang out to voicemail and calls that came in after closing.
- Sort them. Next to each one, mark whether it was a new customer, an existing customer, a vendor, or spam. Calling a few back helps if you are not sure.
- Count the callbacks that failed. How many of the new-customer calls did you reach in time, and how many had already gone elsewhere?
- Price a booked job. Use what an average job or visit actually brings in for your business, after materials if you prefer.
| Line | What to write down | Your number |
|---|---|---|
| A | Unanswered calls in two weeks that were new customers | ________ |
| B | Of those, how many you think you would have booked if someone answered (your honest guess) | ________ |
| C | What one booked job is worth to you | $________ |
| D | B times C, times two, for a rough monthly figure | $________ |
| E | Monthly cost of the AI receptionist you are considering | $________ |
| F | Hours a month you now spend returning calls and playing phone tag | ________ |
If line D is comfortably above line E, the service has room to pay for itself, before counting the time on line F. If D is close to E or below it, the case is weak and you should look hard at the "not worth it" list below. If line A is near zero, you probably do not have a phone problem, whatever anyone tells you.
For line E, providers publish very different prices; the cost guide lists examples. Ours starts at $297 a month for an AI voice agent, with packages on the pricing page.
When it pays, and when it does not
Signs an AI receptionist is worth it
- You are on a roof, under a sink or with a patient when the phone rings, and you cannot step away
- A real share of your calls arrive at night, early morning or on weekends
- Callers ask the same few questions over and over
- In your experience, a new customer who reaches voicemail rarely waits for a callback
- You lose evenings to returning calls and leaving voicemails
- You want appointments booked into a calendar while you sleep
Signs it is not worth it yet
- Someone already answers nearly every call during the hours people call
- Most calls need a judgment call, a diagnosis or a quote only you can give
- Your call volume is a few calls a week
- Your hours, prices and services change constantly and nobody would update the agent
- Your callers mostly need a person for legal, medical or emotional reasons
- You are hoping it will fix a sales problem that is not about answering the phone
Can AI answer phone calls well enough?
Yes, AI can answer phone calls, and the question is what it does once it has picked up. HighLevel's help center, which documents the platform we build on, describes Voice AI agents that answer questions from a knowledge base you supply, collect caller information, update contact records, book appointments, trigger follow-up and route callers to a person when human help is needed.
The same documentation recommends testing an agent with both web calls and real phone calls before it goes live, and notes that call transfers have to be checked on a phone call. That is good advice for anyone buying: the version you hear in a demo should be tested on your actual line before customers reach it.
Our AI voice agent page covers inbound and outbound calls, and the appointment booking page covers the calendar side.
How often is AI incorrect? What to know about accuracy
Language models can produce wrong answers, and they can do it in a confident tone. The National Institute of Standards and Technology names this risk in its Generative AI Profile, a companion to its AI Risk Management Framework: confabulation, the production of confidently stated but erroneous or false content. Among the actions it suggests is checking the sources behind what the AI says.
No one can give you an honest, general percentage for how often an AI receptionist is wrong, because it depends on the model, on the information loaded for your business, and on what your callers ask. Be careful with any provider that quotes a precise accuracy figure without explaining how it was measured. The Federal Trade Commission has warned businesses that claims about what an AI product can do need evidence behind them, and its Operation AI Comply sweep targeted companies making deceptive AI claims.
So are AI answers accurate? On a well-built receptionist, the answers to covered questions should be, because they come from facts you approved. The risk sits at the edges: a question nobody anticipated, a caller who phrases things oddly, or information that went stale. Those are managed, not eliminated, by telling the agent to decline topics it should not touch, transferring certain calls, and reviewing call summaries after launch.
What a careful setup still will not do
- Give legal, medical or financial advice, even if a caller insists
- Act as a HIPAA compliance program or take clinical or patient-record detail
- Quote a firm price on a job nobody has looked at
- Promise a connection to your booking or practice software before it has been confirmed for your account
- Be right about information nobody gave it
Test one before you pay for it
The cheapest test is a phone call. Our main line is answered by an AI receptionist built the same way as the ones we set up. Call it and try these.
- Ask an ordinary question your customers ask every week
- Ask the same question in a different way, or with background noise
- Ask something it should not know and listen for whether it admits that
- Ask to speak to a person and see what happens next
- Leave a message with details and check how complete the summary is
- Interrupt it mid-sentence, the way real callers do
What to ask any provider before you sign
- Who writes the agent's answers, and who updates them when my business changes?
- Can I hear a working agent on a real phone line, not a recording?
- What happens when a caller asks for a person, or asks something outside the script?
- How are calls counted and billed, and what is the overage rate?
- Will I get a summary or recording of each call, and where does it go?
- If you make outbound calls for me, how do you handle consent? The FCC ruled in 2024 that AI-generated voices count as artificial voices under the Telephone Consumer Protection Act, so robocall consent rules apply.
- Who owns the phone number and the call data if I leave?
- Does any feature depend on text messaging, and is that live today?
Texting is not live yet. Voice works today. Text messages (missed call text back, text reminders and texted review requests) switch on once carrier approval clears; that approval is the A2P 10DLC registration US carriers require for business texting from a regular local number. For us, that means call summaries and follow-up go by email for now.

A word on AI voice agent ROI calculators
Many providers offer an AI voice agent ROI calculator on their website. They can be a useful prompt for thinking, but look at what is filled in before you type anything: a preset share of missed calls, a preset conversion rate, a preset job value. Those defaults decide the answer. If you replace every default with your numbers from the worksheet above, the calculator and the paper worksheet should agree. If they do not, trust the one you can check.
If your numbers say it is worth trying, the AI receptionist for small business page explains what we set up and how. If they say it is not, that is a fine answer too, and the call to our line is still free.
