If you're a tradie, consultant, or service provider, you spend hours writing quotes and proposals. ChatGPT can draft them in 30 seconds. You still need to fill in the numbers and check the details, but the structure and language are done for you.
"I'm an electrician in Wellington. A customer wants a quote for installing 6 downlights in their living room in a 1990s house. They currently have a single fitting. Write a professional quote that includes: labour (estimate 3 hours at $85/hr), materials (6 LED downlights at $35 each, wiring, mounting hardware estimated at $80), a note about checking the ceiling cavity first, GST, and a 30-day validity period. Format it as a simple quote they can understand."
ChatGPT will produce a structured quote with line items, totals, GST, and terms. You'll need to:
The first quote takes 2 minutes instead of 15. Once you have a template that works, you can reuse the prompt for every job — just change the details.
For bigger jobs — renovations, ongoing services, consulting engagements:
"I'm a marketing consultant in Auckland. A potential client (a dental practice in Remuera) wants a proposal for a 6-month social media management engagement. Write a proposal that covers: scope (2 posts per week on Instagram and Facebook, monthly strategy call, monthly performance report), timeline (6 months starting August), pricing ($1,500/month plus ad spend), deliverables, and terms (30-day notice for cancellation). Professional but not corporate — they're a small practice, not a corporation."
If you struggle with what to write on invoices:
"I'm a landscape gardener. I just completed a job for a client in Grey Lynn — removed 3 trees, cleared the section, laid new lawn, and cleaned up green waste. It took 2 days. Write a clear, professional invoice description that lists the work done line by line. I'll add the prices myself."
Once you have a prompt that produces a good quote or proposal, save it. You can paste the same prompt every time and just change the specifics. This is where the real time saving is — not the first time, but the 20th time.
ChatGPT will estimate costs if you ask it to. Those estimates are often wrong. Always fill in your own real prices. Never send a quote with AI-generated pricing — you'll either undercharge or confuse the customer.
