An answering service puts a human on your calls and bills per call or per minute. An AI receptionist answers every call or missed call for a flat monthly price and can text, book and log leads, but it handles unusual or emotional calls worse. For most small trade and service shops, the right setup is AI first and a person for the calls that matter.
What each one actually is
An answering service is a company with staff who pick up when you do not. They take a message, sometimes book an appointment, and pass it to you. You pay for what you use or for a bundle of calls.
An AI receptionist is software that answers or follows up on its own. Some tools answer by voice. The kind we build works by text: a missed call gets a text, the assistant answers from facts you approved, offers real open times and books one.
A hybrid uses AI for the first reply and the routine questions, and a person for anything sensitive.
What they charge
These are list prices from each vendor's pricing page, checked in October 2026. Vendors change them.
| Provider | Type | Plans listed |
|---|---|---|
| Aira | AI receptionist | $24.95 for 30 calls, $59.95 for 90, $159.95 for 300, $299 for 600; extra calls $0.70 to $1.50 each |
| Smith.ai | Live receptionist | $300 for 30 calls, $810 for 90, $2,100 for 300; extra calls $8.50 to $11.50 each |
| Ruby | Virtual receptionist | $250 for 50 minutes, $395 for 100, $720 for 200, $1,725 for 500 |
Smith.ai also lists an AI-first option that we could not see priced on that page, so we have left it out.
A worked example, 100 calls a month
This is arithmetic on the list prices above, not a forecast for your shop.
- Aira Premium: $59.95 covers 90 calls. Ten extra calls at $1.00 is $10, so about $70 a month.
- Smith.ai Basic: $810 covers 90 calls. Ten extra calls at $10.50 is $105, so about $915 a month.
That is a gap of roughly $845 a month for the same call count. Bills for human services also climb with call length, because plans like Ruby's are measured in minutes.
Those are rented tools. A built system has a different shape: a build of $1,000 to $5,000, then a monthly care plan at half the build price, with a $1,000 minimum, so $1,000 to $2,500 a month. That covers hosting, AI usage, upkeep, updates and support, and you own what we build. On monthly cost alone a rented AI tool is cheaper. The reasons to build are in the next sections.
What each does best
| Job | Answering service | AI receptionist |
|---|---|---|
| Upset or emotional caller | Better. A person can calm someone down | Weaker. Should hand off fast |
| Same question 30 times a week | Costs per call each time | Cheap and consistent |
| After hours and weekends | Available, billed per call | Available at a flat price |
| Booking a real time slot | Depends on the service | Strong when wired to your calendar |
| Odd or one-off request | Better. A person can improvise | Should pass it to you |
| Writing every lead into a CRM | Usually manual or an add-on | Natural when it is built into your CRM |
| Speed | Rings answered quickly | A text goes out in about a minute |
The honest read: AI wins on volume, speed and cost. People win on judgment and warmth. Neither is right for everything.
Where an AI receptionist falls short
- It can say something wrong. That is why a good build only answers from facts you approved and says "the owner will answer that" for the rest.
- It does not read a room. A caller who is scared about a flooded kitchen needs a quick, human tone. Build in an instant hand-off to a person.
- It needs set up and checking. Someone should read the conversations weekly and fix gaps.
- Some callers will not text. For those you still want voicemail or a person.
What a good hand-off looks like
The hand-off is the whole game. A good one sends you the name, the number, what the person asked and what the assistant already said, in one message, within seconds. A bad one sends "customer needs assistance" and makes you start from zero. Ask any vendor to show you a real hand-off before you pay.
Questions to ask any vendor
- Does it answer by voice, by text or both?
- What happens when it is not sure? Does a person get the full conversation right away?
- Can it book into my real calendar, or does it only take messages?
- Can it handle Spanish-speaking callers? Houston is a bilingual city, so test it, do not assume.
- What counts as a call, and what does an extra one cost?
- Who owns the call recordings and the customer list?
- Can I read every conversation?
- What happens to my data if I stop paying?
Then test it yourself. Call or text it at 9 PM from a number it has never seen and ask something odd.
Why build one instead of renting
Renting is usually cheaper to start. We say that plainly. Building makes sense when:
- You want it wired into your CRM and calendar, so a booking is a record, not an email.
- You want it built around how you work: your hours, your service areas, your questions.
- You want to own the system and the data in it, not rent it from a vendor.
- You want one system for text-back, booking, follow-up and a dashboard.
If a $25 to $60 tool covers your needs, use it. We will say so on the free call.
See what this looks like on our AI receptionist case study. The live demo is private, so we run it with you on a call. For the mechanics of the first text, read missed call text back, explained.
Which fits which business
| Business | Where we would start |
|---|---|
| Plumber, HVAC or roofer on jobs all day | AI text-back and booking, a person for emergencies |
| Detail or tint shop | AI text-back, a person confirms price |
| Med spa or salon | Hybrid: AI books consults, staff answer treatment questions |
| Therapy practice | A person or a secure intake process, not an AI conversation about clients |
| Law firm | A live person. Callers are often in a stressful moment, and coverage matters |
Some callers need a human, not a faster text. SchedulingKit summarizes a 2024 Clio study in which 60% of law firms did not pick up a secret-shopper intake call, which shows how often even professionals miss that first moment.
A simple way to decide
Answer four questions.
- How many calls do you miss in a month? Count voicemails and calls you never saw.
- What is a booked job worth? Multiply the two to see the size of the problem.
- How many of those calls are routine? Hours, pricing ranges, area, booking.
- Who will check the conversations? Somebody has to read them every week.
If most missed calls are routine and you have no one to answer them, start with AI. If most calls are sensitive, long or relationship-heavy, a person is the better first hire. If it is both, use the hybrid.
