No more switching between 5 tools to run a build.
The supplier moat
Your entire supplier network, working inside your estimates.
Most platforms just look up supplier prices. Build Margin runs a real two-sided marketplace: suppliers have their own portal, product catalogue, and RFQ inbox. They quote back to you in-platform.
6 RFQs
Sent in one click from inside the estimate.
One inbox, every quote
Compare side-by-side. No more chasing across email and SMS.
Built for you

Australia-first, not retrofitted
Built around the way AU residential actually works.
NCC 2022 line items
7-star NatHERS, condensation, livable housing, waterproofing — pre-mapped into estimates.
HIA contracts native
Fixed-price, cost-plus, and renovation contracts with the right milestone templates.
SOPA-aware claims
VIC payment claims with magic words and 10-day deadline tracking. NSW, QLD, WA coming.
“The platform replaced three separate tools we were running. Quoting feels noticeably faster, and the client experience is more professional than anything we used to send.”
