How an AI Receptionist Helped an Auckland Plumber Capture $180K in Revenue

Vincent van den Berg1 February 20265 min read

When we first met Dave (name changed for privacy), he was running a successful plumbing business in Auckland with a team of 4 plumbers. Business was good, but he had a nagging feeling he was leaving money on the table.

The Problem

Dave's team was on job sites 8-10 hours a day. When customers called, the phone often went to voicemail. Dave would try to return calls during lunch or after work, but by then, many customers had already called a competitor.

We analysed Dave's call data and found that his business was missing an average of 12 calls per day. At his average job value of $800, even converting 10% of those missed calls represented significant lost revenue.

The Solution

We set up an AI voice agent for Dave's business that:

  • Answered every call within 2 seconds
  • Understood common plumbing enquiries
  • Booked appointments directly into his scheduling system
  • Sent customers a confirmation text
  • Qualified emergency vs routine jobs
  • Transferred urgent calls to Dave's mobile
  • The Results (After 6 Months)

  • **Calls answered:** 100% (up from ~60%)
  • **New jobs booked:** 38% increase
  • **Revenue increase:** $180,000 annualised
  • **Customer satisfaction:** Significant improvement based on Google review scores
  • **Cost:** Less than $200/month
  • Dave's Take

    "I was sceptical at first — I didn't think a computer could handle my customers. But the feedback has been incredible. Customers actually prefer it because they get an instant response instead of leaving a voicemail and hoping I call back."

    The lesson? For service businesses where every call could be a job, having an AI answer the phone isn't a luxury — it's a revenue multiplier.
