What’s included

Seven tabs. One complete system.

Every sheet feeds into the next. Enter your project details once and they flow through the whole file — from your initial budget through to the live dashboard that updates automatically as the build progresses.

Tab 01

Setup & Project Details

Enter your project info once and it flows through the whole file — property address, contract details, key contacts, and project timeline.

Tab 02

Budget Tracker

Track every cost from estimate through to final payment. Auto-calculated projected totals and remaining budget update in real time as you enter invoices.

Tab 03

Trade Register

Manage all contractors in one place — licence numbers, insurance expiry dates, contract details, and payment tracking so nothing slips through.

Tab 04

Stage & Inspection Planner

Plan and track every build stage with progress %, dates, and mandatory inspection records. Know exactly where you are at any point in the build.

Tab 05

Permit & Compliance Log

Log every permit, approval, and compliance document with expiry tracking. Never miss a renewal or submit work without the right approvals in place.

Tab 06

Variation Register

Record every scope change with cost and time impact before work starts. The register that prevents end-of-project surprises and protects your budget.

Tab 07

Live Project Dashboard

A single-screen summary of budget, progress, trades, and permits that updates automatically. The view you want at every site meeting and council inspection. All data from the other six tabs feeds here — no manual updates required.

The story behind it

“I left a government career to build our family home as an owner builder with no construction background. Every spreadsheet I found was either too simple to be useful or too generic to reflect how a real build works. So I built this one.”

— from mzt

The creator of this tool walked away from a stable government career to become an owner builder on a residential project with no prior construction experience. What followed was a steep learning curve in budgets, trades, council approvals, mandatory inspections, and the very specific chaos of trying to manage a build without a background in any of it.

Refined across the full length of that first build, then improved again on subsequent residential projects. Every tab reflects a real problem that came up during construction — not a theoretical framework applied to building, but a system shaped by how a residential project actually unfolds.

The result is a workbook that reflects how a build actually works: the variations that appear mid-stage, the insurance certificates that expire at the worst moment, the inspection that can’t happen until three other things are done first. Whether you’re the owner builder or a PM managing the job, this is the system they wish they’d had from day one.

Who it’s for

Built for real builds.

Owner Builder

Starting from scratch

You’ve just received owner-builder approval and don’t know where to start. Set this up on day one before anything else moves.

Site Manager

Running the job

You’re managing the project for someone else and need a system that handles trades, stages, permits, and budget without scattered notes.

Cost-Conscious Builder

Protecting the budget

You’ve been burned by blow-outs or verbal variations before. The variation register and budget tracker exist specifically for this.

Mid-Build

Picking it up partway through

Already into the build and realise basic spreadsheets aren’t cutting it. Designed to be picked up mid-project without losing existing data.

Your build. Your money. Your control.
