Let me tell you the story of how a $67,000 framing quote nearly became a $67,000 framing invoice — and how a piece of software I built for myself caught what I never would have.
The setup
I'm an owner-builder on the Central Coast of NSW. Two-storey knockdown rebuild, lakefront, 252 square metres. No construction background. The kind of project that makes tradies raise an eyebrow when you tell them you're running it yourself.
By the time I got to framing, I'd already survived demolition, asbestos removal, slab prep, and a solid month of "you should really hire a builder" from everyone I know. I was tired, stressed, and honestly just wanted to tick the next box and move on.
That's the exact moment you're most vulnerable to a bad quote.
The quote
The framing carpenter came recommended by someone in my network. Seemed solid. Turned up on time, walked the slab, looked at the plans. A few days later, the quote landed in my inbox.
$67,000.
For a 252m² two-storey frame, supply and install. Prefab frames from a local truss manufacturer. I had no idea if that was good, bad, or somewhere in between. I'd budgeted roughly $55–60K based on some early research, but honestly? I didn't have enough data to know if my budget was wrong or his quote was high.
A year earlier, I would have just paid it. "He came recommended, the number feels close-ish, let's go."
But by this point, I'd already been building Bildr — the tool that would eventually become this product — and I'd started feeding my own quotes into the system.
What the AI flagged
I pasted the quote into the tool. Within about 30 seconds, it came back with three things:
Now, I want to be clear: the tool doesn't tell you a quote is "wrong." It tells you where it sits relative to benchmarks and flags anything that looks unusual. It's not a replacement for talking to actual humans — it's a starting point for a conversation you'd never know to have.
The conversation
Armed with this, I went back to the carpenter. Not aggressively — just honestly.
"Hey mate, I've been looking at the numbers and the rate seems a bit above what I'm seeing for similar builds in the area. Can you break it down for me — labour vs materials, and what's included in the supply?"
Turns out, his quote included supplying the prefab frames himself through his own supplier. I'd already been quoted by Heyden Frame and Truss directly — and their price was significantly lower for the same spec. He'd marked up the frame supply by about $8K.
On top of that, his labour rate was about 15% above what other carpenters in the area were quoting for similar scope. Not outrageous — but not competitive either.
I told him I'd be supplying the frames myself and asked if he could sharpen the labour rate. He came back at $51,000 — frame install only, with me supplying the prefab frames separately.
Same tradie. Same scope. Same quality of work. $16,000 less.
Could I have caught this without the tool?
Honestly? Probably not. Here's what I would have needed to do:
Ring around 4–5 other carpenters for comparison quotes (1–2 weeks of chasing). Research benchmark framing rates per square metre for my area (a few hours, and the data is hard to find). Understand enough about frame supply vs install to know the quote included both. Know that supplying frames myself was even an option.
I was already working 60-hour weeks between the build and my day job. That research wasn't going to happen. And that's the point — most owner-builders don't have the time, knowledge, or energy to verify every quote that lands in their inbox. So they pay what's asked and hope for the best.
Use this checklist on your next quote
Whether you use Bildr or not, run every trade quote through these red flags before you sign. Tap any that apply to your situation:
What I'd do differently
If I could go back and do this again from scratch, here's what I'd change:
The bigger picture
$16,000 on one trade. That's framing alone. An average owner-builder build involves 15–25 different trades. If even a handful of those quotes are 10–20% high and you don't catch it, you're looking at tens of thousands in overcharges across the project.
That's not a theory — that's maths. And it's the reason I built Bildr. Not because I wanted to start a SaaS company. Because I was staring at a $67,000 invoice and had no way of knowing if it was fair.
Now I do. And if you're owner-building, you should too.
