Five Australian Excel workbooks for the money jobs most households and small businesses face each year. Every tool in one download.

1. House + Granny Flat Analyser (Excel + interactive web version). Cash flow, yield and the return on the granny flat build, plus the after-tax result for each owner when you own the property in shares like 70/30. Includes a 10-year projection.

2. Rental Property Tax-Time Workbook. Log rent and expenses all year under the ATO rental schedule categories, for up to 5 properties and 2 owners. Net rent is split by ownership share for your accountant.

3. Side-Hustle Tax Tracker. Salary plus a side business? Track income and expenses month by month and see how much extra tax to set aside, using 2026-27 resident rates. Optional GST tracking.

4. 13-Week Cash Flow Forecast. A weekly cash balance for the next quarter, with BAS, PAYG and super built in. Weeks below your buffer turn amber, weeks below zero turn red.
