Why PlanWrench
Trade context, not enterprise theatre.
The best estimating workflow is the one your team actually uses: clear enough for the office, quick enough for site, and grounded in the rates and assemblies your work is built from.
PlanWrench brings Australian cost data, reusable trade templates, and project profitability into one practical workspace—so a quote is more than a number sent out the door.
The working toolkit
From plan mark-up to margin check.
One place for the details that decide whether a project pays.
A repeatable way to price the work.
Pull from reusable assemblies, labour allowances, HVAC equipment pricing, ductwork and pipework rates, and local materials data without rebuilding your logic every time.
Less guesswork between the lines.
AI-assisted scope interpretation helps turn plans and specifications into a clearer estimating starting point.
Quotes that look like you mean it.
Professional quote templates and subcontractor comparison sheets keep the handover as sharp as the estimate.
Keep the profit in view.
Mark-up and margin calculators connect estimating decisions to project cost and profitability tracking.
