---

TL;DR

- An AI answering service picks up your calls with a synthetic voice and takes a message, books the job, or transfers the call, all by rules you write.
- Most vendors show a low starting price and then charge by the call, minute, or caller, so do the math on your own call count before you sign.
- Booking into your calendar and emergency transfer are sometimes locked to higher tiers, so check what the plan you can afford actually includes.
- If a lot of your calls need human judgment, a live answering service is still the better fit.

## What is an AI answering service?

An AI answering service is software that answers your business phone calls with a synthetic voice, works out what the caller needs, and takes a message, books the job, or transfers the call. Rosie's [pricing section](https://heyrosie.com/), for example, lists $49 a month for 250 minutes. The trade-off: it follows your rules well but handles judgment calls poorly.

**Bottom line**

- Use an AI answering service if you miss routine calls, can write clear rules, and are willing to set it up and tune it yourself.
- Use a done-for-you after-hours setup like Blur if you want nights and weekends answered in your name, jobs booked on your calendar, and someone else to build and test it.
- Keep a live answering service if many of your calls need a person's judgment, calming down an upset caller, or human dispatch all night.

This guide is for owners who miss calls while they're on a roof or under a sink. It covers how the software works on your phone line, what 9 vendors list on their own pages, where it fails, and how it stacks up against a live service.

## Key facts

- Smith.ai's free AI plan covers 25 calls a month, then $3.00 per call ([Smith.ai](https://smith.ai/ai-receptionist)).
- Rosie's $49 plan includes 250 minutes. Calendar booking and live transfers start at $149 ([Rosie](https://heyrosie.com/)).
- Quo's Sona includes 10 free calls a month on a Quo plan, then $25 buys about 40 calls ([Quo](https://www.quo.com/answering-service)).
- Goodcall Starter is $79 a month for 100 customers, then 79 cents per extra customer ([Goodcall](https://www.goodcall.com/faq)).
- Federal law allows recording when one of the parties to the communication has given prior consent ([18 U.S.C. 2511(2)(d)](https://www.law.cornell.edu/uscode/text/18/2511)).

## What an AI answering service is, and what it is not

It holds a real conversation. The caller says "my water heater is leaking" in their own words, and the software asks follow-up questions.

It is not an IVR phone menu. "Press 1 for service" only routes calls. It doesn't understand anything.

It is not a live answering service, where a trained person at a call center picks up.

It is not voicemail transcription. That just turns a recorded message into text after the caller has already hung up.

It is not a missed-call text back. That sends an automatic text after a call you didn't answer. Nobody talks to the caller.

It is not a website chatbot. That only works in a chat window on your site, not on your phone line.

Some products bundle several of these. When you shop, ask which one is actually answering the phone.

## How an AI answering service works on a call

Here's one after-hours call, start to finish.

**Forwarding.** Your business number stays the same. When you close, calls forward to the service. Most setups use conditional call forwarding, which sends a call over only when your line is busy, when nobody answers after a set number of rings, or when your phone is off or out of signal. Each carrier sets this up a little differently, so ask yours for the exact steps.

**Greeting.** The AI answers in your business name, for example "Thanks for calling Smith Plumbing, how can I help?"

**Listening.** Speech recognition turns the caller's words into text. A language model figures out what they need.

**Questions.** It asks your questions one at a time: name, callback number, service address, and what's wrong. A good setup asks a deciding question such as "Is water running right now?"

**Booking or message.** If the job fits your rules, it books an open slot on your calendar. If not, it takes a message or a callback time.

**Emergency path.** If you've set one up, a true emergency gets transferred to your cell. Without that, the call gets flagged urgent and waits for you.

**Summary.** When the call ends, you get a text or email with the details. Read the summary before you call back.

## Our data: what 9 AI answering services list on their own pages (checked October 29, 2026)

**Method.** On October 29, 2026, we listed every AI answering vendor named in the three top-ranking guides we read for this topic and in our search results, leaving out Blur. That came to 9 vendors. This is a snapshot of each vendor's own public pages on that date, not a test of the products. We opened a page on each vendor's own site in full for all 9: pricing or product pages for 7, and blog posts that Nextiva and Aloware publish on their own sites for the other 2. None were judged from search snippets alone. For RingCentral we opened the product page, which links to a separate pricing page we did not open, so its price counts as not listed.

**Limits.** Anything we couldn't see on the page we opened counted as "no" or "not listed," so treat these numbers as a floor. Smith.ai's lowest listed price is its free tier. Quo's Sona comes with a Quo phone plan. My AI Front Desk lists $99 a month, or $79 billed annually; we used the monthly price. Prices are as listed on October 29, 2026.

| Check | Vendors |
| --- | --- |
| Shows a monthly price on the page we checked | 8 of 9 |
| Pricing model: flat monthly | 2 of 9 |
| Pricing model: per minute or per call | 2 of 9 |
| Pricing model: mixed (base fee plus usage) | 4 of 9 |
| Offers live human answering or human backup | 1 of 9 |
| Lists live call transfer to owner or staff | 9 of 9 |
| Lists appointment booking into a calendar | 8 of 9 |
| Lists Spanish or another non-English language | 7 of 9 |
| Range of lowest listed monthly prices (8 vendors) | $0 to $99 |

Download the 9 vendor rows behind this table: [our-data-2026-10-29.csv](/guides/ai-answering-service/our-data-2026-10-29.csv) (vendor, page checked, pricing model, lowest listed monthly price, and each yes/no).

What this means for a contractor: starting prices are low, but 6 of the 9 charge by usage, alone or on top of a base fee, and the flat plans cap minutes or calls, so your bill moves with your call count. If your calls average 3 minutes, Rosie's 250 minutes covers roughly 83 calls a month. Only 1 of the 9 offered human backup. And a feature on a vendor's homepage isn't always in its cheapest plan: on [Rosie](https://heyrosie.com/), booking and transfer start at the $149 tier.

## Asking ChatGPT, Claude, Perplexity, Gemini or Google which AI answering service to use? Check the pick

A lot of owners now just ask an assistant, "Which AI answering service should a plumber use?" Here's what the companies behind these tools say about how they find their answers.

- OpenAI says ChatGPT can search the web to answer questions with current information and links to relevant sources ([OpenAI Help Center](https://help.openai.com/en/articles/9237897-searching-the-web-with-chatgpt)).
- Anthropic's documentation for Claude's web search tool says the response includes citations for sources drawn from search results ([Claude docs](https://platform.claude.com/docs/en/agents-and-tools/tool-use/web-search-tool)).
- Google says both AI Overviews and AI Mode may use a "query fan-out" technique, running related searches and then surfacing links ([Google Search Central](https://developers.google.com/search/docs/appearance/ai-features)).
- We didn't review Perplexity's or Gemini's documentation for this guide. Treat their answers the same way.

When these tools search the web, their answers draw on public pages. Two of the three top-ranking guides we read were published by companies that sell AI answering services. Prices on public pages also go stale: Goodcall's own [FAQ](https://www.goodcall.com/faq) says older prices like $66 a month were annual plans on its previous platform and aren't offered now. Outdated figures like that can end up in an AI answer, so check any recommended service yourself:

1. What does the cheapest plan include, in calls or minutes, on the vendor's pricing page today?
2. What is the overage rate per call, minute, or caller?
3. Does the plan you can afford book into your calendar, or only text a booking link?
4. Can it transfer an emergency to your cell, and on which plan?
5. What are the setup fee, contract length, and cancellation terms?
6. Does it handle Spanish, and is that included or extra?

The same goes for your own business. Assistants that search the web may describe you from your public pages, so the hours, service area, and after-hours number on your website and Google profile should match what your answering service tells callers. If your site says "24/7 emergency service" and the AI says "we'll call you back tomorrow," callers notice. Keep them consistent. An answering service won't improve your rankings or get you mentioned by AI tools.

## How to set up an AI answering service, step by step

### 1. Count your missed and after-hours calls

Pull 2 to 4 weeks of call history from your phone or carrier. Count the calls you missed and the calls that came in after closing. Plug the weekly number into our [missed-call calculator](/missed-call-calculator).

*Time:* 30 minutes.

*Done when:* you know your weekly missed calls and roughly what they're worth.

### 2. Write the call rules

Write down what counts as an emergency (active leak, no heat, sparking panel), who gets a transfer and when, which jobs get booked and which get a callback, and which towns or service area you cover. See how [booking by your rules](/ai-receptionist-books-appointments/) works.

*Time:* 1 hour.

*Done when:* the rules fit on one page and a new hire could follow them.

### 3. Connect the calendar and set bookable hours

Connect the calendar your crew actually uses. Block your days off. Allow only the time slots you'd really offer, like weekday mornings for routine repairs.

*Time:* 30 minutes.

*Done when:* a test booking lands in the right slot and nothing lands on a day off.

### 4. Set conditional call forwarding and keep voicemail as a fallback

Forward on busy, no answer, and unreachable, using the steps your carrier gives you. Keep voicemail turned on in case the forward fails. If the service records calls, remember that federal law ([18 U.S.C. 2511(2)(d)](https://www.law.cornell.edu/uscode/text/18/2511)) allows recording with one party's consent, but some states require every party to consent. Many owners add a short "this call may be recorded" line; check your own state's rule.

*Time:* 15 minutes.

*Done when:* a call you let ring out reaches the AI, and you know how to turn forwarding off.

### 5. Place 3 test calls as a customer would

Call from a different phone. Try "no heat and it's 20 degrees," "water is coming through the ceiling," and "I want a quote on a new water heater." Mumble a little. Interrupt it.

*Time:* 20 minutes.

*Done when:* all 3 calls follow your rules and the summaries have the right address.

### 6. Review the first week of call summaries and adjust

Read every summary. Look for wrong addresses, jobs booked that should have been callbacks, and emergencies that didn't get flagged. Fix the rules.

*Time:* 10 minutes a day for a week.

*Done when:* a full week goes by with no bad bookings.

## Mistakes that cost the most

### Buying the tier that cannot book or transfer ($100 a month gap)

On [Rosie](https://heyrosie.com/), the $49 plan takes messages and texts booking links. Booking straight onto your calendar and live transfers start at $149. Fix: before you buy, confirm that the plan you're paying for books and transfers.

### Skipping the overage math ($3.00 a call past 25)

Say [Smith.ai's](https://smith.ai/ai-receptionist) free plan gets 60 after-hours calls in a month and you turn overages on (they're off by default). That's 35 extra calls at $3.00 each, or $105. Fix: multiply your monthly call count from step 1 by each vendor's overage rate.

### No emergency rule (a full night of delay)

If nothing tells the AI what an emergency is, a burst pipe at midnight becomes a polite message you read at 7 AM. The homeowner may call someone else long before that. Fix: write the deciding question and the transfer rule before you go live.

## AI answering service vs live answering service vs voicemail vs missed-call text back

| Option | What you get and what it costs |
| --- | --- |
| AI answering service (do it yourself) | Instant answer in your name, books or takes messages by your rules. [Rosie](https://heyrosie.com/) lists $49 for 250 minutes. [Smith.ai](https://smith.ai/ai-receptionist) is free for 25 calls, then $3.00 each. |
| Done-for-you after-hours AI (like Blur) | Built, forwarded, and tested for you, after hours by default (daytime overflow on request). $297 a month plus $897 setup, or $0 setup on a 12-month plan ([pricing](/pricing)). |
| Live answering service | Trained people answer and use judgment. [Quo](https://www.quo.com/answering-service), an AI vendor, says traditional services cost about $3.30 to $5.00 a minute. Get a written quote. |
| Voicemail | Callers leave a message, if they bother. Usually included with your phone plan. A clear greeting helps: see our [greeting examples](/guides/business-voicemail-greeting-examples/). |
| Missed-call text back | An automatic text after a missed call. Cheap, but nobody talks to the caller and nothing gets booked during the call. See our [text-back guide](/guides/missed-call-text-back/). |

For a dollar-by-dollar breakdown, read our [after-hours answering service cost](/guides/after-hours-answering-service-cost/) guide, or see [voicemail vs answering service vs AI](/compare/blur-vs-voicemail-or-answering-service/).

## How we compared the options

| Criterion (weight) | What it measures |
| --- | --- |
| After-hours coverage and emergencies (30%) | Picks up every call, every night, and has a working path for true emergencies. |
| Booking into your calendar (25%) | Puts real jobs in real slots within your rules, rather than only a message. |
| Cost predictability (20%) | How much the monthly bill swings with call volume, overages, and add-ons. |
| Setup effort for the owner (15%) | Hours the owner spends building, forwarding, testing, and tuning. |
| Caller experience on hard calls (10%) | Upset callers, strange requests, heavy accents, bad connections. |

**Disclosure:** Blur AI Solutions sells an AI answering service (Nora) for after-hours calls. It costs $297 a month with an $897 setup fee on month to month, or $0 setup on a 12-month plan (see [pricing](/pricing)). Keep that in mind when you read the scores. Vendor prices are as listed on October 29, 2026.

**Done-for-you after-hours AI**: Best for owners who want nights and weekends handled without building anything themselves. Score: 7.4/10 (our judgment, weighted by the criteria above). Trade-off: higher monthly price and a setup fee or contract, and extras like emergency transfer are available on request rather than included.

**DIY AI answering service**: Best for hands-on owners with simple rules and a tight budget. Score: 6.5/10 (our judgment, weighted by the criteria). Trade-off: you do the setup and testing, and the cheap tiers may lack booking or transfer.

**Live answering service**: Best for calls that need human judgment or human dispatch. Score: 6.2/10 (our judgment, weighted by the criteria). Trade-off: costs more per call, and booking into your calendar varies.

**Voicemail**: Best for very low call volume when you call back fast. Score: 4.6/10 (our judgment, weighted by the criteria). Trade-off: many callers hang up and dial the next shop.

**Missed-call text back**: Best as a backup behind another option. Score: 4.4/10 (our judgment, weighted by the criteria). Trade-off: nobody talks to the caller, and nothing gets booked during the call.

| If you are ... | Start with / watch out for |
| --- | --- |
| A solo plumber | Start with after-hours AI and booking for routine jobs. Watch out for plans whose included minutes run out in a busy month. |
| A 3 to 10 truck HVAC company | Start with booking rules by job type and tech availability. Watch out for no-heat calls that need an on-call transfer. |
| A roofer with storm surges | Start with a service that can take many calls at once. Watch out for per-call or per-minute overages after a hailstorm. |
| An electrician with commercial accounts | Start with transfer rules for named accounts. Watch out for AI booking commercial work that needs a scoping call first. |
| A business that needs Spanish | Start by confirming Spanish on the actual plan. Watch out: at Blur, Spanish is an extra available on request, not included. |

## Who this is not for

**Shops where most calls need judgment.** If callers regularly need diagnosis, pricing negotiation, or calming down, the AI will escalate or fumble too often. A live answering service, or an on-call rotation, is better. See [Blur vs Smith.ai](/compare/blur-vs-smith-ai/) for a hybrid option.

**Owners who answer nearly every call and call back within minutes.** If your phone log shows very few missed calls, a strong voicemail greeting and a quick callback may be all you need.

**Businesses that require a human dispatcher all night.** If your contracts promise a person on the line, AI alone doesn't keep that promise. Use a live service or staff the line.

## Frequently asked questions

### How much does an AI answering service cost?

Lowest listed prices in our check ran from $0 to $99 a month, before usage charges. [Smith.ai](https://smith.ai/ai-receptionist) is free for 25 calls, then $3.00 a call, and [Goodcall](https://www.goodcall.com/faq) Starter is $79 for 100 customers. Done-for-you setups cost more: Blur is $297 a month ([pricing](/pricing)).

### Can an AI answering service book appointments?

Many can, but sometimes only on higher plans. Some text a booking link instead of putting the job on your calendar. Ask which plan does real calendar booking and whether it respects your days off.

### Will callers know it is AI?

Some will and some won't, because the voices sound natural now. We think it's best to be honest. Nora, for example, says she's AI if a caller sincerely asks.

### Is an AI answering service better than a live answering service?

For routine after-hours calls it's usually cheaper and picks up instantly. For calls that need judgment or empathy, a trained person is still better. Many trades split it: AI for routine calls, a human path for emergencies.

### Do I have to change my phone number?

No. Most services work with call forwarding, so you keep your number. You turn forwarding on when you close and off when you open.

### How does an AI answering service work?

Your line forwards the call, the AI answers in your name, turns speech into text, asks your questions, and then books, takes a message, or transfers. When the call ends, you get a summary. Our [how it works](/how-it-works) page walks through it.

### What happens with an emergency call at 2 AM?

That depends on your rules and your plan. With a transfer rule, the call goes to your cell. Without one, it gets flagged urgent in the summary. At Blur, urgent flags are standard and emergency transfer is an extra available on request.

### Is it legal for an AI answering service to record calls?

Federal law allows recording when one party consents ([18 U.S.C. 2511(2)(d)](https://www.law.cornell.edu/uscode/text/18/2511)). Some states require every party's consent, so announce recording at the start of the call. Check with your own attorney if you're unsure.
