SolutionsCapability

Every call answered. Every lead captured. Booked onto your calendar.

An AI voice agent is a phone line that never goes to voicemail: it answers around the clock, works out what the caller needs, routes the emergencies, and books the routine work. We build them white-labeled to your business — your name, your rules, your calendar — not a generic bot with your logo on it.

What we build
01

24/7 inbound answering

Answers on the first ring, day or night, in the business's own voice — and answers every call at once, so two callers never hit a busy signal.

02

Qualification & booking

Captures who's calling and what they need, separates urgent from routine, and books directly onto the calendar or system you already run.

03

Escalation & transfer

Emergencies ring a human immediately. Warm transfer, ring groups, and on-call routing are configuration, not custom work.

04

Owner visibility

Every call logged, transcribed, and reported — what it handled, what it cost, what it booked.

Shipped and live

PlumbDesk, our AI receptionist for plumbing companies, answers real customer calls today. We built the agent, the billing, and the CRM behind it — and wrote up what was actually hard.

Common questions

What owners ask before they commit.

How much does a custom AI voice agent cost?
Deeper consulting and solution builds start at $1,000. What a voice agent costs depends on how many lines it answers, what it has to connect to, and how complex your call routing is. We quote a fixed price after the free Leak Report, so you see the number before anything gets built.
How long does it take to build an AI voice agent?
A working voice agent typically ships in four to six weeks. The first two weeks are the diagnosis and the call flows; the rest is building, testing against real calls, and connecting it to your calendar and CRM.
Will it work with the phone system I already have?
Yes — you keep your existing number and your existing phone system. The agent sits in front of or alongside what you already run, so nothing has to be ripped out and your team learns no new software.
What happens when the AI does not understand a caller?
It hands off to a human rather than guessing. We set explicit rules for what the agent may decide alone and what it must escalate, and anything outside those bounds rings a person immediately.
Can callers tell they are talking to AI?
Most callers know quickly, and we do not try to hide it. What matters to them is that someone picked up, understood the problem, and booked the job — and we can add a disclosure to the greeting where two-party consent law requires it.
How do I know it is actually working?
Every call is logged, transcribed, and reported monthly against three numbers: calls answered, jobs booked, and cost per call handled. If those numbers do not justify the system, we tell you first.

Would this pay in your business? Let's find out first.

We don't open with a build — we open with the Leak Report: a free first call, then a written diagnosis of your pipeline with a dollar figure on each gap. If this build isn't where your numbers say the money is, we'll tell you what is.
