5 ways small business owners can protect their margins as growth cools

September 3, 2026

Australian small business sales are still growing, but the pace is slowing.

The latest Xero Small Business Insights data shows sales growth eased to 6.5% year-on-year in the June quarter, down from a two-year high of 7.9% in the March quarter. Interest rate rises and elevated fuel prices are squeezing household budgets, and the impact is being felt most in hospitality, retail, and arts and recreation, while mining, utilities and construction continue to outperform. Job growth has slowed too, suggesting owners are becoming more cautious about hiring.

In a slower-growth environment, protecting margins matters more than chasing revenue. That doesn’t mean cutting costs indiscriminately. It means having a clear view of where money is being made, where it’s leaking, and what the business can actually afford.

1. Know where your margin is really coming from

Sales figures alone don’t reveal profitability.

Look at the margin on individual products, services and customers. Some may generate strong revenue but leave little behind once labour, materials and delivery costs are factored in.

A quarterly review, even a rough one, can show which parts of the business are pulling their weight and which are quietly dragging on profit. Your accountant can provide a useful second set of eyes, helping to spot patterns an owner may be too close to see.

2. Review costs before you cut them

When growth slows, cutting costs looks like the obvious move. But cutting the wrong ones can weaken the business further.

Go through recurring expenses: software, suppliers, insurance, finance, overheads, and ask whether each is still earning its keep, or whether a more efficient alternative exists. The goal isn’t to spend less for its own sake. It’s to make sure every dollar spent is still working for the business.

3. Keep a close eye on cash flow

Profit and cash flow are not the same thing. A business can look profitable on paper while struggling to pay its bills if too much cash is tied up in unpaid invoices or stock.

Xero’s latest data shows small businesses waited an average of 22.9 days to be paid in the June quarter, though Xero notes the improvement was partly due to normal end-of-financial-year payment patterns rather than a lasting trend.

Tracking what’s owed, what’s due, and when cash is expected to land makes pressure easier to spot before it becomes a crisis.

4. Think twice before adding fixed costs

Slower growth is a good moment to test whether a new cost is genuinely necessary.

Hiring is the clearest example. A new employee can be the right call if they’ll generate revenue, clear a bottleneck, or let the business take on more work. But adding a permanent cost without a clear need puts lasting pressure on margins, and the same logic applies to premises, equipment and other long-term commitments.

Before signing up to anything long-term, it’s worth weighing the expected return against the effect on cash flow, a calculation that’s often easier with an accountant’s eye on the numbers.

5. Check that your prices still work

Rising costs can quietly erode margins even when prices stay exactly the same.

Work out what it actually costs to deliver each product or service today: labour, materials, transport, everything, then check whether current prices still leave the margin the business needs.

That doesn’t automatically mean raising prices.

It means basing pricing decisions on today’s costs, not assumptions carried over from

a year ago.

Testing a few pricing scenarios, often something an accountant can help model, can show how different approaches could affect the bottom line.

Protect the margin before chasing growth

The latest figures don’t suggest Australian small businesses are in retreat. Sales are still growing, just more slowly, and the impact is uneven across industries.

For owners, that makes financial visibility more important than ever. Knowing which work is genuinely profitable, where costs are creeping up, when cash is due to arrive, and what the business can realistically afford, all of that becomes more important when growth slows.

Protecting the margin on the business you already have can be just as important as finding the next source of growth.
