The problem
Manual operational bottlenecks cost you revenue.
Every delayed response is a customer who needed immediate execution — and transitioned to a competitor instead.
An inbound service request arrives late at night. Your core team is offline. The inquiry sits in a queue. The customer hangs up and routes to the next alternative on Google.
The problem isn’t lack of intent. It’s that manual human intervention cannot scale across every hour of every day — and the operational load arrives anyway.
That’s not a missed interaction. That’s automated revenue your competitor just captured.
82% of consumers say they will call a competitor if a business doesn’t answer.

Questions
AI receptionist questions, answered.
What happens when my business misses a phone call?
With Zynvox, the caller gets a text back within seconds, the AI finds out what they need, books them in and logs it to your CRM. Without it, most callers simply try the next business.
How do I stop losing leads when my phone is on silent?
Let an AI receptionist cover the line. Zynvox answers by voice or texts back instantly whenever you can’t pick up — in a meeting, on a job, or after hours — and books the lead for you.
Can AI answer my business phone after hours?
Yes. Zynvox answers and follows up 24/7, including nights, weekends and holidays, and books appointments on your real calendar so you wake up to confirmed jobs.
What is Zynvox?
Zynvox is an AI receptionist and workflow automation platform. When a call is missed it replies in seconds by text or answers by AI voice, qualifies the customer, books the appointment, updates your CRM and sends reminders — 24/7.
Which businesses is Zynvox for?
Any business that depends on inbound calls: home services such as HVAC, plumbing and electrical, law firms, dental and medical clinics, real estate, auto repair, property management, insurance, salons and B2B sales teams.
What is missed-call revenue leakage?
It is the revenue lost when a customer can’t reach you and buys from a competitor instead. Estimate it as missed calls per month × the share that would have booked × the share who go to a competitor × average job value × 12 months. Not every missed call is a lost sale, so spam, wrong numbers and existing customers are left out.
How fast does Zynvox respond to a missed call?
Within seconds. The text-back goes out while the customer still has the phone in their hand, before they call the next business on the list.
Can Zynvox answer calls with an AI voice?
Yes. The AI Receptionist answers live calls in a natural voice, understands what the caller needs, and books or routes the call. For calls that are missed, Zynvox follows up instantly by text.
Does Zynvox update my CRM?
Yes. Every lead, conversation, qualification answer and booking is logged automatically, so your team never re-types information. We confirm the integration for your tools on the analysis call.
How is Zynvox different from basic automation tools?
Rule-based tools run the same steps every time and forget the context. Zynvox holds real conversations, keeps a memory of your customers and business rules, and suggests improvements from past outcomes — which only take effect once you approve them.
Does Zynvox send reminders and follow-ups?
Yes, to customers who agreed to receive them: appointment reminders, maintenance or recall reminders, follow-ups for open quotes, and review requests after the job — on the schedule you set. Every message honours STOP.
How much does Zynvox cost?
Founding partners choose Starter ($197 one-time setup + $79/month) or Pro ($497 setup + $197/month). Both start with a 14-day free trial: you pay nothing unless you stay, and only then are the setup fee and monthly plan charged. After the 5 founding spots, Starter will be $497 + $129/month and Pro $997 + $349/month.
What is the difference between Starter and Pro?
Starter covers one location by text — missed-call text-back, qualification, booking, CRM logging and emergency escalation. Pro adds AI voice answering, reminders and review requests, up to 3 locations, and we set everything up and tune it for you each month.
What happens if a customer calls at 2 AM with an emergency?
It is escalated, not booked for the morning. Your on-call person is paged by call and text straight away, the customer is told someone is coming only after that person accepts, and if nobody accepts within 5 minutes it goes to your backup and then the owner. Anyone in danger is told to call 911 first.
What does the AI do when it’s confused?
It stops and hands over. The customer is told a team member will follow up, and your team gets the full transcript. It never invents prices, discounts or promises.
Is texting customers back legal?
A single reply to someone who just called your business, about their call, is a response to their own contact, not marketing. Reminders, review requests and offers go only to customers who agreed to them, and every message honours STOP and HELP. Confirm the rules for your industry with your attorney.
Does Zynvox record calls?
No. Zynvox does not record phone calls. Text conversations are saved so your team can see what was said.
Do callers know they’re talking to AI?
Yes. The first text and the first spoken line say it is your business’s automated assistant, and anyone who asks for a person is offered one.
How does Zynvox learn?
From your rules and each customer’s history. It suggests improvements based on patterns it sees, but nothing about routing, pricing or booking changes until you approve it.
When it isn’t a routine call
Emergencies, confusion, consent.
The questions every owner should ask before letting software answer their phone — answered here, not in the fine print.
Emergencies
Escalated to a person in minutes. Never booked into a later slot.
- You define what counts as an emergency (for example: no heat below freezing, no cooling with children or elderly people at home, active leak, no power).
- An emergency is never put into tomorrow’s calendar. Your on-call person is paged by phone call and text at once, or a live call is transferred to them.
- The customer is told help is coming only after a technician says yes. If no one answers in 5 minutes, it calls the backup, then the owner.
- Danger to life (gas smell, fire, sparks, carbon monoxide, a medical emergency): the caller is told to get safe and call 911 first, then your team is alerted.
When the AI isn’t sure
It stops and hands over. It never guesses a price or a promise.
- If it doesn’t understand, the customer repeats themselves, sounds upset or asks for a person, it says a team member will follow up and hands over with the full transcript.
- It only quotes the prices and policies you have approved. Anything else — a discount, a warranty question, a complaint — goes to a person.
- During your hours, live calls can be transferred to your staff instead.
Texting rules & consent
One reply to the person who called you. Nothing else without their OK.
- The instant text-back answers someone who just called your business, about their own call. It is not marketing.
- Reminders, review requests and offers are only sent to customers who agreed to receive them, and that consent is logged with the date.
- Every conversation honours STOP (opts out at once, confirmed) and HELP (your business name and contact details).
- Follow-ups are only sent between 8 AM and 9 PM in the customer’s time zone.
AI disclosure
Customers are told they’re talking to an automated assistant.
- The first text says it is your business’s automated assistant, and the first spoken line on a call says the same.
- If anyone asks “Am I talking to a real person?” it answers honestly and offers a person.
- Zynvox only answers and replies to people who contacted you. It does not make AI cold calls.
Your customers’ data
Used only to run the service for you. Never sold.
- Caller numbers, messages and booking details are used only to answer, book and follow up for your business.
- We do not sell personal information. It is shared only with the providers needed to run Zynvox, such as hosting and texting.
- You or your customers can ask for data to be accessed, corrected or deleted at any time.
How it learns
Your rules plus each customer’s history. You approve every change.
- What it knows comes from you: services, prices, service area, hours, who is on call and what counts as urgent.
- It remembers each customer’s past jobs, equipment and preferences, so nobody is asked the same question twice.
- It spots patterns (for example, emergencies peaking after 6 PM) and suggests a change. Nothing about how it routes, prices or books changes until you approve it.
This describes how Zynvox is set up. It is not legal advice: texting and disclosure rules vary by state and industry, so confirm what applies to your business with your own attorney.
