🛡️ Refund pathway
Refund pathway
If this is not what you need, email our contact page for a full refund within 30 days of purchase. No questions and no friction.
Prior buyers who bought the toolkit when it was advertised as containing “2024-2025 Brisbane pricing as the baseline” - that representation was inaccurate (figures are 2018-2020 dollars). If that affects your decision to keep the product, the refund pathway above applies.
📅 In practice
How to use this in 2026
Open the workbook. Replace the Coorparoo dollar values with your own current trade quotes as they arrive. Keep the category structure, the ratios sheet and the payment schedule - those translate to any Brisbane Queenslander build. Use the contingency calculator to pressure-test your total before you commit.

ℹ️ FAQ
Budget Toolkit - FAQ
How is the Budget Toolkit different from the free Budget Tracker?
The free Budget Tracker is the raw Coorparoo cost data as a read-only reference spreadsheet - all 8 categories, every line item, the actual figures paid. The Budget Toolkit is a planning tool with guided worksheets for entering your own quotes, actuals-vs-quote comparison columns, contingency calculators, trade payment schedule templates, stage-by-stage inspection hold points, notes on items over initial estimates and where we saved and a glossary of cost line items. It is designed to be used through your own project, not just as a reference.
What format is the toolkit?
The toolkit is an Excel (.xlsx) workbook with multiple worksheets. It works in Google Sheets as well, though some conditional formatting may not carry across.
Is this professional cost advice?
No. The toolkit is a planning tool based on one project's experience. It is not a quantity surveyor's report, a builder's quote or professional financial advice. Use it for informed planning and always get multiple quotes from licensed professionals.
How do I receive the toolkit after purchase?
Lemon Squeezy emails your download link as soon as payment is confirmed. The link works for repeat downloads from your purchase email, so save the file straight away.
Can I get a refund?
Yes. If you change your mind for any reason within 30 days of purchase, email us for a full refund - no questions, no friction. Australian Consumer Law guarantees apply separately. See the refund pathway lower on this page.
