How a Melbourne Tradie Used AI to Win More Jobs and Cut Quote Time in Half
Composite case study based on real patterns from Australian tradespeople using AI. Names are illustrative.
Ready-to-use AI prompts built for tradies — quoting, scheduling, compliance and more.
Dave is a plumber based in Melbourne’s eastern suburbs. Sole operator, occasionally subcontracts. Good reputation, mostly word-of-mouth. His problem: he was drowning in the admin side: quotes took forever to write, Google reviews went unanswered for weeks, and his job management system was basically a notes app. He’s been using AI for six months. Here’s what changed.
The Quote Problem
Dave was spending 30–45 minutes writing each quote. Not because the work was complicated: because he hated writing and kept second-guessing the wording. He’d have the numbers in five minutes but spend another 40 on the actual document.
His fix: a ChatGPT prompt template saved to his phone. He fills in the job details (customer name, location, scope, materials, price) and the prompt generates a professional quote in his voice. He checks the numbers, adds his ABN and payment terms, and sends it as a PDF. Total time: 8 minutes instead of 40.
“Write a professional quote for a plumbing job in Melbourne. Customer: [name]. Job: [description]. Total price: $[amount] inc GST. Materials included: [list]. Timeline: [timeframe]. My business name is [name], ABN [number]. Tone: professional but friendly. Include a brief scope of works, what’s included, payment terms (50% deposit, balance on completion).”
Google Reviews
Dave had 23 Google reviews with 11 unanswered. He spent one Sunday afternoon with ChatGPT writing responses to all 11, then set up a reminder to respond to new reviews within 48 hours using the same prompt approach. His Google rating went from 4.2 to 4.6 within three months: partly from new reviews from happy customers he proactively followed up.
Follow-Up Messages
The biggest win: ChatGPT-drafted follow-up messages. When a quote goes out, Dave sends a WhatsApp follow-up 48 hours later if he hasn’t heard back. Short, friendly, not pushy. He drafts them in ChatGPT and sends manually: takes 2 minutes. His quote conversion rate improved noticeably because he was actually following up consistently rather than forgetting.
Cost and Time
- ChatGPT Plus: ~AU$28/mo
- Time saved on quotes: ~3 hours/week
- New jobs won from better follow-up: “at least 2–3 extra jobs a month”
At Dave’s hourly rate, the time saving alone pays for ChatGPT many times over. The extra jobs from better follow-up are harder to measure but clearly real.
What He Tried That Didn’t Work
Zapier automation for review responses: too much setup for a sole operator who just wanted to keep it simple. AI-generated social media content: he found it felt inauthentic for his trade and stopped. The lesson: use AI for the tasks that genuinely save you time; ignore the rest.
