The Challenge

James Mitchell runs a two-person plumbing team in Melbourne's south-east suburbs. Like most tradies, he spends his days on job sites — under houses, in roof spaces, or elbow-deep in a hot water system.

The problem was simple but costly: every missed call was a missed job. With hands full and noise drowning out his ringtone, James estimated he was missing 3 to 4 calls per day. A traditional answering service quoted him $180/month with per-call fees on top, and the quality was inconsistent — operators would get suburb names wrong or fail to capture the urgency of a burst pipe.

After-hours calls were even worse. Emergency plumbing calls between 6 PM and 8 AM would go straight to voicemail, and most callers never left a message — they just called the next plumber in the search results.

The Solution

James set up Vervox AI in under 10 minutes. He configured his service area (Cranbourne, Narre Warren, Berwick, Clyde, and surrounding suburbs), listed his services (hot water systems, leak detection, blocked drains, gas fitting), and picked a professional male voice.

The AI now answers every call instantly — during jobs, after hours, and on weekends. It collects the caller's name, suburb, issue description, and urgency, then sends James an SMS and push notification with the full lead details. Emergency keywords like "burst", "flooding", and "gas leak" trigger urgent notifications so he can prioritise.

James forwarded his existing business number to Vervox, so callers dial the same number they always have — the experience is seamless.

The Results

Within the first month, James saw a dramatic improvement:

  • Lead capture rate jumped from 55% to 94% — nearly every call is now a captured lead.
  • 35% of his monthly leads now come from after-hours calls he would have previously missed entirely.
  • The average cost per call dropped from $4.50 (answering service) to $0.06 with Vervox.
  • His Google reviews improved because callers commented on how quickly they got a response.

Most importantly, James no longer stresses about missed calls when he is on a job. He checks his leads dashboard between jobs and calls people back in priority order based on the AI's urgency scoring.

I used to lose 3-4 calls a day when I was under a house fixing pipes. Now every single call gets answered and I get a text with the details before I even come up for air. It's paid for itself ten times over.
