Cash Flow vs Profit: What Business Owners Need to Understand

Key takeaway: A profitable business can still run short of cash. Profit measures performance over a period; cash measures what is in the bank today. With interest rates up a full percentage point this year and super now paid each payday, the gap between the two deserves closer attention.

Why profit and cash differ

The profit and loss statement records income when it is earned and expenses when they are incurred. Cash moves on a different timetable. The main reasons are:

• Debtors. A sale is profit on the invoice date, but cash arrives when the customer pays.

• Inventory. Stock is paid for before it is sold, and it sits on the balance sheet, not in the P&L, until then.

• Creditors. Paying suppliers sooner or later shifts cash without changing profit.

• Capital spending. Equipment is paid for upfront but expensed over years through depreciation.

• Loan repayments. Principal repayments use cash but are not an expense.

• Tax timing. GST, PAYG withholding, tax instalments and super are collected or paid on their own schedules.

• Owner drawings and dividends. These reduce cash but not profit.

A worked example

Consider a business with $10 million of annual revenue and an $800,000 profit. If customers stretch payment from 45 to 60 days, about $411,000 more is tied up in debtors. Profit is unchanged, but the bank balance falls by that amount.

Now add financing. Since the start of 2026 the cash rate has risen from 3.60% to 4.60%. On a $3 million variable facility, a one percentage point increase adds about $30,000 a year in interest. That cost does reduce profit, and it lands every month.

What has changed

Two developments in 2026 have tightened cash for many businesses:

• Higher interest rates. The RBA has raised the cash rate four times this year, and markets expect further increases.

• Payday Super. Since 1 July, super guarantee must reach employees' funds within 7 business days of each payday. Cash that once stayed in the business until after quarter-end now leaves with each pay run.

Rising fuel, freight and energy costs add further pressure where they cannot be passed on quickly.

Who is affected

Growing businesses are often most exposed, because growth consumes cash before it produces it. Businesses with long project cycles, large inventories, seasonal trade or a few large customers are also vulnerable.

Commercial implications

Cash shortfalls rarely arrive without warning. They show up first in the working capital measures: debtor days lengthening, stock building, and creditor payments being stretched. Watching these monthly gives time to act before the bank balance forces a decision.

Recommended considerations

1. Maintain a rolling 13-week cash flow forecast and compare it with actual cash each week.

2. Track debtor days, inventory days and creditor days monthly, and calculate the cash conversion cycle.

3. Tighten credit terms and collections: invoice promptly, follow up early and consider deposits on large jobs.

4. Plan capital spending and loan repayments in the cash forecast, not just the budget.

5. Set aside GST, PAYG and super as they accrue.

6. Prepare a three-way forecast covering profit, cash and balance sheet before seeking finance.

7. Talk to your lender early if covenants or limits look tight.
