The Problem
You're a builder in Hamilton. A homeowner submits a quote request through your website on Tuesday evening: "Looking to build a 20sqm deck off the back of the house, kwila timber, with a simple balustrade."
You see the enquiry Wednesday morning between jobs. You think about it during the day. Thursday you sit down after dinner and start putting numbers together. Material costs, labour hours, consent fees, GST. You email the estimate Friday morning.
By then, the homeowner has already received a quote from another builder who responded Wednesday afternoon. They've signed. You did the work of pricing the job, and someone faster got paid for it.
This is one of the biggest pain points in the NZ trades. Buildxact, a dedicated estimating platform, costs $300+ per month. Fergus handles job management and quoting but takes time to learn and set up. Most small operators in NZ still price jobs manually, using spreadsheets, handwritten notes, or memory. The estimate itself isn't the hard part. The speed is.
Research shows that the first business to respond to an enquiry wins the job in over 50% of cases. In trades, where customers often submit three or four quote requests at once, response time is the single biggest competitive advantage.
The typical pattern: a homeowner posts on Builderscrack or Nocowboys, or emails three builders from a Google search. The first one to reply with something concrete wins the conversation. The rest are backup options at best. If your estimate arrives two days later, you're competing against a builder who already has a relationship with the client.
It's not that your pricing is wrong or your work isn't good. It's that by the time you respond, the customer has already moved on. The job went to the builder who showed up first, not the builder who showed up best.
What We Built
A branded web form where potential customers describe their job. They select a category (deck build, bathroom renovation, kitchen refit, fencing, painting), enter basic measurements and specifications, and choose their preferred finish level (standard, mid-range, premium).
The system generates a detailed estimate within 60 seconds. It includes itemised line costs for materials and labour, GST calculated correctly, an estimated timeline, and a professional PDF proposal branded with your logo, contact details, and terms.
The customer gets a polished document immediately. You get an email notification with the full details so you can follow up with a phone call or site visit.
Demo scenario: A homeowner in Tauranga visits a local builder's website at 8pm on Sunday. She fills out the form: "Bathroom renovation, 6sqm, remove existing shower and bath, install walk-in shower and freestanding bath, mid-range fixtures." Within a minute she receives a branded PDF: line items for demolition, plumbing rough-in, waterproofing, tiling (floor and walls), fixtures supply and install, painting, and a contingency allowance. Total estimate: $28,500 + GST. Estimated timeline: 3 to 4 weeks.
She's impressed. No other builder has responded yet, and this one already has a detailed breakdown on her screen. She books a site visit for Monday morning. The builder hasn't lifted a finger yet, but he's already the frontrunner for the job.
How It Works
Three components work together behind the form:
- A structured input form that captures job type, dimensions, specifications, and finish preferences. The form is customised to your trade and the types of jobs you typically do. It asks the right questions so the estimate is relevant, not generic. A deck builder's form asks about timber type, height off ground, and access. A painter's form asks about number of rooms, ceiling height, and surface condition.
- An LLM with NZ trade pricing knowledge. The AI model is configured with current NZ material costs, typical labour rates for your region, and standard job structures. It breaks the customer's description into individual line items, assigns costs, calculates labour hours, adds GST, and estimates a timeline. You review and adjust the pricing data periodically to keep it accurate.
- A PDF generator that formats the estimate into a professional proposal document with your branding, payment terms, and disclaimers. The PDF is emailed to the customer and copied to you automatically.
This is not a replacement for your expertise. It's a first-response tool. The estimate gets the conversation started. You follow up, visit the site, and provide a final quote based on what you actually see.
The PDF includes a clear disclaimer that the estimate is indicative and subject to a site inspection. This sets expectations correctly while still giving the customer something concrete and professional to review immediately. It positions you as responsive, organised, and serious about their project.
The form also captures the customer's name, phone number, email, and address. That means every enquiry becomes a lead in your pipeline, whether or not they proceed immediately.
The Impact
- Respond to enquiries in minutes, not days. The customer gets a professional estimate before they've finished contacting your competitors. At 8pm on a Sunday, at 6am before work, on a public holiday. The tool doesn't take days off.
- Win more jobs by being first. Speed of response is the number one factor in which tradesperson gets the job. This makes you the fastest responder every time, even when you're on site and can't check emails.
- Spend less time on admin. Instead of spending an hour per estimate at the kitchen table after work, the system handles the first draft. You review and refine only the jobs worth pursuing. That's hours back every week.
- Look professional from the first interaction. A branded PDF proposal with line items and GST signals that you run a serious operation, not a one-man-band with a ute.
- Cost comparison: Buildxact costs $300+ per month ($3,600/year). This tool costs $399 once. For a small operator doing 5 to 10 quotes per week, the ROI is immediate.
One additional benefit: the tool captures every enquiry as a lead. Even if the customer doesn't proceed immediately, you have their details, their project description, and the estimate they received. That's a warm lead list you can follow up with next month or next quarter.
What It Can't Do
- The estimate is indicative, not final. Site conditions, access issues, hidden damage, and consent requirements can all change the actual cost. The tool provides a starting point for conversation, not a binding contract.
- Pricing accuracy depends on the data you provide. If material costs change or your labour rates shift, you need to update the system's reference data. It won't track market prices automatically. We recommend a quarterly review of your pricing inputs.
- Complex, multi-trade projects (full house renovations, new builds) are too variable for a simple form-based estimate. The tool works best for defined job types: decks, bathrooms, kitchens, fencing, painting, roofing.
- The AI calculates based on standard job structures. Unusual configurations, heritage buildings, or highly custom work may produce estimates that need significant adjustment. The tool works best when the job type is well-defined and repeatable.
- This is a lead capture and first-response tool. It doesn't manage your project schedule, invoicing, or job tracking. It sits alongside your existing workflow, whether you use Fergus, Tradify, or a paper diary.
- The tool doesn't replace your professional judgement. Every estimate should be followed up with a site visit for any job over a few thousand dollars. The AI gets you in the door. Your expertise closes the deal.
