AI Receptionist for Small Business: The Costs and Math Nobody Publishes
- Software you run yourself commonly costs $25-$300 a month as of July 2026, plus your own hours to set up and babysit. Done-for-you builds run a flat monthly price.
- The missed-call math: missed calls x share that's new business x average job value x close rate. For most service businesses that's hundreds to thousands of dollars a month.
- My two products: The Missed-Call Fix at $147/mo answers the calls you can't take, and The AI Receptionist at $500/mo answers every call, 24/7. Both built and watched for you.
- The honest exception: if you miss fewer than about 10 calls a month, or your phones are already answered live around the clock, don't buy this. The math won't clear.
An AI receptionist (also sold as an AI virtual receptionist or an AI phone answering service) is software that answers your business phone in a natural voice, holds a real conversation, and either books the job or takes a structured message with the caller’s name, number, and what they need. Voicemail records and waits. An IVR tree (“press 1 for sales”) routes button presses but can’t converse. A human answering service puts a live person on the line reading your script, billed by the minute.
The AI version sits in the middle: it converses like an operator, costs like software, and never sleeps, which is why it’s become the default answer for after-hours answering and overflow. The rest of this page is the part vendors skip: what it costs, what the missed calls are already costing you, and when the whole thing isn’t worth buying.
Before you price any answering service for your business, price the leak. The formula is four numbers you already have or can count in a week:
missed calls per month x share that are new business x average job value x close rate
Three worked examples with clearly made-up but realistic numbers. Swap in your own before believing any of them.
| Example business | Missed calls/mo | New business share | Avg job value | Close rate | Walking out the door |
|---|---|---|---|---|---|
| Plumber | 20 | 50% | $450 | 40% | $1,800/mo |
| Dental office | 30 | 40% | $600 | 50% | $3,600/mo |
| Salon | 25 | 60% | $80 | 50% | $600/mo |
That’s the number every option below has to beat. If you want the deeper version of this workup, including what hiring a person actually costs fully loaded, it’s in the cost-math guide.
Prices below are what each vendor published as of July 2026. They move often, so verify before you buy. I’ve tried to be fair to everyone here; these are all real products that work for somebody.
| Product | Listed price | What’s not in the sticker | Who sets it up and watches it |
|---|---|---|---|
| Upfirst | Entry plan listed around $24.95/mo as of July 2026 | Call and minute caps per plan; you write and test the scripts | You |
| Rosie | Around $49/mo per their published pricing in July 2026 | Minute allotments; setup, testing, and tuning are on you | You |
| Smith.ai | Around $95/mo for 50 calls as of July 2026, then roughly $2-2.40 per call | Per-call billing climbs fast in a busy month | Their team, from your instructions |
| RingCentral | No published price. Their pricing page says contact sales | Whatever the sales call decides; you won't know until you're on it | You, inside their phone system |
| Dialzara | Entry plan $29/mo with 60 minutes included, per their pricing page in July 2026 | $0 setup fee, then $0.48 a minute once you're past the 60 | You |
| Typical human answering service | Commonly $50-100/mo base plus $1-2 per minute | Per-minute rounding rules; long calls get expensive quietly | Their operators, reading your script |
| The Missed-Call Fix (Tanner Preserve) | $147/mo flat, published right here | Nothing. The price is fixed and published, not invented on the spot | Me. Built, tested, and watched for you |
| The AI Receptionist (Tanner Preserve) | $500/mo flat, no setup fee | Covers up to 200 minutes of AI call time plus monitoring; bigger volume gets scoped before you sign | Me. Built, tested, and watched for you |
Six things to ask any vendor before you hand over a card. Every one of these has surprised a business owner I’ve talked to.
- Setup fees. Some services charge a few hundred dollars before the first call is answered. Ask, because it's rarely on the pricing page.
- Per-minute vs. per-call billing. A per-call price looks clean until you learn what counts as a call. A per-minute price looks cheap until a chatty caller runs eight minutes.
- Overage rates. The advertised plan covers a set volume. The rate after that cap is the number that actually decides your bill in a good month.
- Phone number fees. Some platforms charge monthly for the number the AI answers on, on top of the plan.
- Texting add-ons. Sending confirmation texts usually costs extra and requires carrier registration (A2P 10DLC) that takes days to weeks to clear.
- Custom pricing means a sales call. If a vendor won't publish a number, budget an hour of your life and a follow-up email sequence to get one.
If you’ve been searching for who builds AI phone answering for contractors, or for any small business, here’s the literal answer: done-for-you builders exist, and I’m one of them. Most of the products in the table above are software you subscribe to and configure yourself. That’s a fine deal if you like tinkering. It’s a bad deal if the whole reason you’re here is that you don’t have time to answer the phone, let alone tune the robot that answers it.
A built-for-you setup includes the parts the subscription doesn’t: writing the scripts around your actual services, testing against your worst-case caller, watching the transcripts after launch, and fixing what drifts. I run Tanner Preserve out of Delafield, Wisconsin and build these for businesses anywhere; the phone system doesn’t care what state you’re in. The price is fixed and published, not invented on the spot: $147 or $500 a month, checkout on the fixes page, no discovery call required. If you’d rather do it yourself, the setup guide walks you through it and doesn’t cost anything.
Not everyone needs the full 24/7 call answering package on day one. The The Missed-Call Fix, $147a month, covers only the calls you couldn’t take: an AI picks up when you don’t, says up front that it’s an AI, takes the job details, and sends them to you in writing right away, with text follow-up to the caller once carrier registration clears. That’s speed to lead for the moments you’re on a roof or in a crawlspace, without changing anything about how your phone works the rest of the day.
The crossover logic is simple. If you or your team answer most calls and the leak is the ones that ring out, the $147 fix captures most of the value for less than a third of the price. If nobody is reliably at the desk, or after-hours calls are a meaningful share of your volume, the full receptionist earns the difference because it answers everything, not just the misses. Buy the small one first if you’re unsure; upgrading later takes a day, not a rebuild.
The failure modes, from someone who reads the transcripts.
If you’ve read a forum thread asking whether anyone actually trusts these things, the skepticism is earned. AI receptionists fail in specific, predictable ways. They mangle an unusual last name and log “Kaczmarek” as “Catch Mark.” They double-book a slot when a calendar sync hiccups. They handle an angry caller with the cheerful patience of a machine that cannot read a room, which makes the caller angrier. And when an integration breaks mid-call, an unwatched setup gives the caller dead air.
None of that is a reason to skip the technology. It’s a reason not to run it unwatched. In my setups, hard names get spelled back to the caller, booking waits for you to confirm the slot rather than writing to your calendar blind, an upset caller gets a fast handoff to a message and an alert to you, and I read transcripts and fix what drifts as part of the monthly price. The difference between a horror story and a system that quietly books jobs is almost never the AI. It’s whether a person is watching it.
Yes. The robocall laws you’ve heard about (TCPA and the state equivalents) regulate outbound calls and the consent behind them, not software answering calls made to your business. Having an AI answer your inbound line is legal everywhere in the US. The practice that keeps you clean and keeps callers comfortable is disclosure: the AI should say it’s an AI at the top of the call. Every system I build does.
Nothing gets ported and nothing about your phone changes. Your existing business number stays exactly where it is.
Your services, hours, service area, and the questions your callers actually ask. Not a generic script with your name pasted in.
You call it, you try to break it, and I fix what wobbles before a single customer ever hears it.
Unanswered calls (or every call, your choice) forward to the AI. The Missed-Call Fix is live within 2 business days; the full receptionist takes about a day of my hands plus your test call.
Curious what the AI would even say for a business like yours? The basics guide covers how these systems talk, book, and take messages.
If you miss fewer than about 10 calls a month, the math doesn’t clear at $147and it definitely doesn’t clear at $500. Same if your phones are already answered live, 24/7, by people you trust: you’ve solved the problem, don’t buy it twice. Count your missed calls for two weeks before spending anything, or run the free audit and let it tell you whether phones are even your biggest leak. Sometimes the honest answer is a better voicemail greeting and a callback habit, and that costs nothing.
How much does an AI answering service cost?
Software you run yourself commonly costs $25 to $300 a month as of July 2026 depending on call volume, with entry plans like Upfirst listed around $24.95 and Smith.ai around $95 for 50 calls. A done-for-you build runs flat: mine are $147 a month for the Missed-Call Fix and $500 a month for the full AI Receptionist, with setup, testing, and monitoring included.
Is there a free AI receptionist for small business?
There are trials and free tiers with tight caps, but nothing you'd want running your business phone long term. Between per-minute charges and your own setup hours, a free plan usually means paying with your time instead of your card. If your call volume is genuinely tiny, voicemail plus a fast callback habit might honestly be enough.
Can AI actually replace a human receptionist?
For booking, qualifying, answering hours-and-pricing questions, and taking clean messages, yes, and it does it at 2am without a bad day. For an upset customer, a complicated quote, or a judgment call, no. A well-built setup routes those calls to a human instead of pretending it can handle them.
Is it legal to have AI answer my business phone?
Yes. The robocall laws (TCPA and state rules) are about outbound calls and consent, not about answering calls people make to you. The right practice, and the one I build in, is having the AI say up front that it's an AI.
Can I keep my existing business phone number?
Yes. Your number stays exactly where it is and unanswered calls forward to the AI. If you ever cancel, you turn off forwarding and your phone works exactly like it did before, nothing held hostage.
Will customers know they're talking to an AI?
With my builds, yes, it says so in the first sentence. Callers mostly don't mind; what they mind is nobody picking up. Hiding it is bad practice and a legal risk in some states, so I don't do it.
What happens when the AI can't answer a question?
It stops guessing, takes a message, and gets it to you in writing right away. In a managed setup the transcript gets reviewed and the script gets updated, so the same question doesn't stump it twice.
What's the difference between an AI receptionist and missed-call text-back?
Missed-call text-back handles only the calls you couldn't take; with my version an AI picks up those calls, takes the job details, and sends them to you in writing for $147 a month. The full AI Receptionist answers every call, 24/7, qualifies the job, and works toward the booking for $500 a month. If you already answer most calls, start with the smaller one.
How long does setup take?
The Missed-Call Fix is live within 2 business days of checkout. The AI Receptionist takes about a day of my hands plus a test call with you, so live in days, not weeks. Text legs come online once carrier registration (A2P 10DLC) clears, which takes carriers days to a few weeks.
What's a missed call actually worth to my business?
Run the formula: missed calls per month, times the share that are new business, times your average job value, times your close rate. For most service businesses that lands between a few hundred and a few thousand dollars a month. Count your own missed calls for a week before you trust anyone's average, including mine.
Both prices published. No form gate, no sales call.
