AI Phone & Enquiry Agent

An AI Receptionist That
Never Misses a Call

Your phone rings while you're on the tools, on the road, or asleep. An AI receptionist answers every call and enquiry 24/7, books the job, qualifies the lead, and routes the rest to your team. Built by the engineer-led team founded by Lakitha Sahan, hosted in Australia.

No account managers, no call centre scripts, just our engineers wiring it into the booking tools you already use.

What an AI receptionist actually does

It is more than an answering machine. The agent holds a real conversation, takes action in your systems, and only involves a human when it genuinely needs to.

Answers calls & enquiries 24/7

Picks up on the first ring, day or night, weekends and public holidays. The same agent handles web form enquiries, missed-call texts and after-hours voicemail so every channel gets a response.

Books jobs & appointments

Checks live availability, offers real slots, and writes the booking straight into your calendar or job-management tool. No double handling, no callback tag.

Captures & qualifies leads

Collects name, number, suburb and what the caller needs, then asks your qualifying questions, so hot jobs are flagged and time-wasters are filtered before they reach you.

Routes to the right person

Urgent breakdown? It can escalate to your on-call mobile. Account query? It books a callback. You set the rules; it follows them and logs a transcript every time.

The real cost of a missed call

Plenty of busy trades and service businesses miss a big slice of their inbound calls, and most callers don't leave a voicemail. They just ring the next name on Google. For example, a shop missing 30% of its calls leaks real money every month. Here is what that looks like.

Worked example: a Melbourne plumbing business

Inbound calls per month
200
Missed (30%)
60 calls
Convert to a job (1 in 3)
20 lost jobs
Average job value
$450 AUD
Revenue walking out the door
$9,000 / month

That is roughly $108,000 a year in work handed to competitors, before counting the lifetime value of repeat customers. An AI receptionist that recovers even half of those calls pays for itself many times over inside the first month.

An AI voice agent and phone answering service in one

People search for an “AI voice agent” or an “AI phone answering service” and a virtual receptionist when they mean the same thing: a phone line that always gets answered without putting another person on payroll. Our AI receptionist is all of those. It picks up the call in a natural voice, understands what the caller wants, and acts on it, rather than reading a fixed menu of press-one options.

Unlike a traditional answering service that just takes a message and passes it on, the AI voice agent completes the job on the call: booking the appointment, confirming the details by SMS, and logging the transcript. You get the coverage of an answering service with the action of a real receptionist, around the clock.

Works with the booking tools you already run

We don't ask you to rip out your systems. The AI receptionist plugs into your existing calendar, CRM and job-management software over their APIs, so a booking it takes appears exactly where your team expects it. Common integrations include ServiceM8, Cliniko, Calendly, Square, HubSpot and Google Calendar.

Under the hood it is the same approach as our custom AI agents and workflow automation: the agent doesn't just talk, it triggers the follow-up actions, sends the confirmation SMS, and updates the record. One accountable team builds and owns the whole pipeline end to end, led by the founder.

Your calls, your data, kept in Australia

Every call your receptionist takes is a customer record: names, phone numbers, addresses and sometimes health or financial details. We process and store that on Australian-hosted infrastructure under your control, not on an offshore platform you can't see into.

That keeps you aligned with the Australian Privacy Principles and gives regulated businesses, clinics, brokers and law firms among them, the data sovereignty their obligations demand. Being Melbourne-based isn't a tagline; it's where your data lives.

Who an AI receptionist suits

Voice agents work both directions

Answering the phone is only half of it. The same voice agent can pick up the calls your team never finds time to make, so the follow-ups, reminders and rebookings actually happen.

Outbound follow-ups

Quotes chased, appointments confirmed, no-shows rebooked. Your agent makes the calls your team never gets to.

Reminders and rebooking

Service due, policy renewing, annual check-up: the agent calls, the customer books, the calendar fills.

Custom voice builds

Anything with a phone line and a workflow behind it. We build custom voice agents end to end, on your stack, in your rules.

Every voice agent is a custom build by our Melbourne engineering team, from receptionist to full outbound campaigns. Australian accent, Australian-hosted, answering 24/7, priced transparently in AUD.
