Overview

PreQual is a lead qualification platform built for the Australian construction industry. It solves a $2.4 billion problem: builders waste massive resources quoting jobs for buyers who aren’t financially ready, don’t have land, or aren’t serious. PreQual verifies buyer intent before they reach a salesperson.

The residential construction industry loses billions annually to unqualified leads. Builders spend weeks preparing quotes for prospects who can’t proceed — no finance pre-approval, no land, no realistic timeline. Sales teams burn out chasing leads that were never going to convert. There was no standardised way to pre-qualify a construction buyer.

Approach & Tools

Key decisions

Qualify on readiness, not interest
Interest is cheap, every enquiry looks keen. Readiness predicts the close. The flow checks the three things that actually gate a build: finance pre-approval, land, and a realistic timeline. A lead that clears all three is worth a quote. One that does not is worth a nurture sequence, not a salesperson’s week.
Score and rank, don’t gatekeep
A hard pass/fail throws away leads that are one step from ready. PreQual scores each buyer by likelihood to proceed and ranks the pipeline, so the builder works the top of the list first instead of treating every enquiry as equal.
Integration-ready, not rip-and-replace
Builders already run a CRM and a sales process. PreQual was built API-first to sit in front of what exists rather than ask a sales team to move house. Qualification happens before the lead lands in their pipeline, clean.

What the client said

“The qualification system Dom built for us filters out time-wasters completely. We’re only talking to build-ready clients. That single change paid for the engagement inside the first month.”
