Updated July 2026
One metric to add in 2026-27
- Tax cash coverage: Track ATO obligations accrued versus cash set aside, because ATO general interest charge incurred from 1 July 2025 is no longer tax deductible. A ratio under one means you are borrowing from the ATO at a non-deductible rate.
- Gross margin on live data: Cloud bank feeds mean margin can be watched monthly, not discovered at year end.
- Wages ratio: With super guarantee at 12%, total employment cost as a share of revenue is the number that quietly moves; watch it including super, not just gross wages.
Frequently asked questions
Which numbers matter most for a small business?
Gross margin, operating cash flow, debtor days, and tax and super obligations accrued against cash actually set aside. Profit on paper does not pay the ATO.
How often should I review the numbers?
Monthly for cash flow and margin, quarterly against your activity statement cycle, and annually for structure and tax planning. Anything less than monthly means problems surface too late to fix cheaply.
Why does tracking ATO obligations matter more now?
Because general interest charge incurred from 1 July 2025 is no longer deductible, and from 1 July 2026 super must be paid each payday rather than quarterly. Both changes remove float that businesses used to rely on.
What is a healthy debtor days figure?
It depends on your industry and your terms, so the useful test is the trend against your own history rather than a benchmark. Debtor days rising month on month is a cash flow problem forming.
