Variations slip.Deadlines pass.Margins disappear. We stop the bleed.

ScopeWise Advisory is a contract administration service for custom home builders in Sydney. We get your progress claims in on time, variation notices in writing, and deadlines tracked — remotely, weekly, and without the cost of a full-time hire — so you can focus on the build, not the paperwork.

Trusted by builders across Sydney.

Contract administration for custom home builders — HIA, ABIC, MBA, Australian Standard.

The problem

Small-to-mid residential builders in Sydney running custom homes, renovations, and alterations — typically on HIA, ABIC, MBA, Australian Standard (AS), or bespoke residential contracts, with project values from $300k to $5M+. If you've got 1–5 active projects and no dedicated contracts person, we're built for you.

  • Variations taking too much time and not tracked cleanly
  • Progress claims are a headache and take too long to pull together
  • Contract paperwork and client admin falling behind while you focus on site delivery
  • Disputes and awkward conversations because things aren't documented clearly

If you're an owner managing a custom build, we also work on your side — reviewing progress claims, assessing variations, and making sure you only pay what's properly due. See our experience working as an owner's representative.

The Margin Maths — the true cost of a missed variation, showing triggers, time-bar rejection, and profit wipeout

A $0 missed variation at 20% net margin requires $0 in new revenue to earn back the lost profit.

We exist to stop those holes from forming in the first place.

The solution

What we do

Progress Claims

Prepare and package your monthly progress claims with the right paperwork, on the right dates — with retention verified and approved variations cross-checked — so you get paid on time and stay compliant.

Variation Notices

Capture scope changes in writing, price them, and get the notice out before work starts. Variations that aren't documented don't get paid.

EOT & Registers

Track delay events and issue EOT notices before the deadline. Keep your variation register, claims tracker, and obligations calendar up to date.

Building a custom home?

We also work as an independent owner's representative — reviewing claims, assessing variations, and protecting your budget. Same contract discipline, on your side.
