AI receptionists for service businesses
Your phone stops going to voicemail.
Hisora builds AI receptionists that answer every call, book straight into your calendar, and text the people who hang up. Built for HVAC, plumbing, legal, real estate and property management — on your own accounts, not ours.
Don’t take our word for it
Try to break it
The number above is answered by Emily, our own receptionist. She is not a sandbox and not a script: she reads a real knowledge base, checks Nour’s real calendar, and books a real appointment. The system that answers your call is the system we would build for you.
Book the call
Tell her what your business is and what you’re losing to the phone. She checks a real calendar and books you in.
Call back and move it
She finds your appointment from the number you’re calling from — you never read out a booking reference.
Ask her what it costs
She’ll tell you the model — a setup fee plus a monthly retainer — and she will not invent a number. That restraint is the part most AI receptionists get wrong.
Ask her something she doesn’t know
How many clients we have, when we started. She says she doesn’t know and hands it to Nour, instead of making something up.
Ask her if she’s a real person
She’ll tell you the truth.
The problem
Every missed call is somebody phoning your competitor next
Service businesses lose work in the fifteen minutes nobody was free to pick up the phone. The caller does not leave a voicemail. They call the next business on the list.
- $50,000–$150,000a year
- is what the American Med Spa Association puts revenue lost to empty chairs at, for a single clinic.
- $449–$779a month
- is what human answering services like Ruby publish as rates, for 50 to 100 minutes of call handling.
- ~35%of calls in a month
- is where vendors put missed-call rates in salons and shops.
What it actually does
Not a voicemail with a nicer voice
- Answers every call, 24/7
- No hold music, no queue, no missed call at 7pm on a Sunday
- Books into your real calendar
- It reads live availability and only offers slots that exist. Different appointment types get different lengths and different staff
- Reschedules and cancels
- It finds the caller’s existing appointment from the number they are calling from
- Texts back the ones who hang up
- A missed call becomes a text within seconds, so the lead does not evaporate
- Sends reminders and follow-ups
- Confirmations, reminders before the appointment, follow-up after — with consent captured on the call and logged
- Knows what it must not say
- Never diagnoses, never quotes a price it wasn’t given, never invents an answer. It says it doesn’t know and takes a message
- Hands off to a human properly
- Transfers during office hours; outside them it says so plainly and takes a message
- Tells you what happened
- Every call logged with a transcript, whether it booked, and whether consent was given
The guardrails
The part nobody demos
An AI receptionist that books appointments is easy. One that knows when to stop is the difference between a tool and something you can leave alone with your customers.
An HVAC agent that hears “I smell gas” stops the booking flow, tells the caller to leave the house and call 911 from outside, and does not try to sell them a service call.
A real estate agent asked to describe a neighbourhood refuses on fair housing grounds, names the reason, and redirects to something genuinely useful. Answering that question is a federal violation, and the helpful answer is the illegal one.
A medical or legal agent never diagnoses, never advises, and never quotes a price that isn’t published.
Each of these is built and demonstrated on the channel. They are not hypothetical.
How it is built
On your accounts, not ours
Your Twilio number. Your calendar. Your CRM. If we ever stop working together, the system keeps running and you keep the keys — there is no Hisora platform to be locked out of, and no per-seat licence.
Built on
Plugs into what you already use
Compliance
The questions your last quote didn’t mention
Most people selling AI receptionists have never read the rules. These are the ones that decide whether your agent is legal.
You cannot text your customers from a new number on day one US carriers require A2P 10DLC registration first. Twilio’s own estimates for the campaign review run from hours to weeks — ours cleared in under two hours, but plan for the slow case. Unregistered messages return success and silently never arrive.
A single upsell converts an appointment reminder into a telemarketing call which needs a different and much higher tier of consent than the one you have.
An AI voice is an “artificial voice” under the TCPA — the FCC ruled on this in February 2024 — and calling a mobile without consent carries statutory damages per call.
Consent has to be captured, logged and revocable including when somebody simply says “take me off your list” out loud to the agent.
We build the consent capture, the opt-out handling and the audit trail in from the start, and we will tell you plainly when something you want is not legal.
Proof
Everything we build, we publish
We document every build end to end on YouTube — the working parts and the parts that broke — with written build guides so you can check the work rather than take our word for it.
Six receptionists, each harder than the last:
- 01A dental clinic that books
- 02A med spa that reschedules and cancels
- 03A law firm that texts callers back
- 04An HVAC company that chases follow-ups
- 05A hardened build that alerts when something breaks
- 06A real estate brokerage built end to end in a single agentic run
Pricing
What it costs
A one-time build fee plus a monthly run fee, quoted once the scope is clear. Most builds take two to three weeks.
Telephony and platform costs are billed to your own accounts by those providers, at cost. Nothing is marked up through us.
