Don't sign a building contract until you've checked the quote.
Most cost blowouts don't come from bad builders. They come from incomplete quotes that no one caught in time.
What BuildWhiz does
BuildWhiz checks your builder's quote for what's missing, vague, or underquoted — before you sign. Upload your quote PDF and get a detailed breakdown of gaps, risks, and the questions you should be asking your builder.
It's not just a report. It's a system for catching problems early, asking better questions, and negotiating from a position of knowledge.
Who it's for
Anyone building, renovating, extending, or doing a knockdown-rebuild in Australia. First-timer or experienced — it doesn't matter. If you're about to sign a building contract, you should know exactly what's in that quote and what isn't.
The problem
Your builder writes quotes every day. You'll probably read one or two in your entire life. That gap in experience is where cost blowouts happen.
A missing electrical allowance can add $5,000–$10,000 later. Vague provisional sums get adjusted upward after the contract is signed. Items left out entirely become variation claims you have no leverage to negotiate. By the time you notice, it's too late.
The only alternative used to be hiring a building advocate or quantity surveyor at $500–$2,000+. BuildWhiz gives you a thorough completeness check in minutes, for a fraction of that.
How it works
Answer a few questions about your project. Upload your quote PDF. BuildWhiz reads every line item, compares it against a personalised checklist of 50+ items across 9 categories, and flags what's missing or unclear.
You get a coverage score, a prioritised list of gaps, and ready-made questions to take back to your builder. When they send a revised quote, upload it again and compare — so you can see exactly what changed.
Analyse. Ask. Revise. Compare. Repeat until you're confident.
Built for Australia
BuildWhiz is built specifically for Australian building contracts. Our checklists cover state-specific requirements — from cyclone ratings in Queensland to bushfire assessments in Victoria. We understand provisional sums, PC items, and the way quotes actually work here.
The goal
We exist for one reason: to give you confidence before you sign. Not after. Not when the first variation claim arrives. Before.
Once the contract is signed, your leverage is gone. BuildWhiz makes sure you use it while you still have it.
