Revenue is up.
The order book looks healthy.
The business is busier than ever.
You may even be reporting a respectable EBITDA.
So why is there never enough cash in the bank?
Why are supplier payments getting harder to manage? Why is the overdraft permanently stretched? Why is the ATO balance growing? Why are you constantly moving money between accounts just to get through payroll?
This is one of the most dangerous paradoxes in business:
A growing business can be running out of cash at precisely the same time that its revenue and reported profits are increasing.
And sometimes growth itself is the problem.
ASIC reported that 14,722 companies entered external administration for the first time during 2024–25, 33.2% more than the 11,053 recorded in 2023–24.
That number requires perspective. ASIC reports that companies entering external administration during the year represented approximately 0.41% of registered companies, still below the peaks recorded in 2011–12 and 2012–13.
Nevertheless, the message for SME owners is important.
Business failure is not always preceded by disappearing customers and collapsing revenue.
Sometimes the warning signs are hidden inside apparently successful growth.
A business can sell more, employ more people, carry more inventory, invoice more customers and report higher accounting profits, while simultaneously becoming financially weaker.
That is why owners need to understand not simply profitability, but cash conversion.

The Dangerous Assumption That Growth Equals Success (Business Growth Perth)
Many owners instinctively regard revenue growth as evidence that the business is improving.
It can be.
But revenue is only the top line.
The more important questions are:
What does it cost you to generate that additional revenue?
How much gross profit does each additional dollar of sales produce?
How much additional working capital does growth require?
How quickly does accounting profit convert into cash?
How much debt is required to finance the growth?
A business increasing revenue from $5 million to $7 million while gross margins deteriorate, debtors expand, inventory builds and borrowings increase may be less financially secure than it was at $5 million.
This is why ambitious owners need to distinguish between growth and sustainable business growth.
As discussed in my article on when ambition for business growth becomes a business risk, growth magnifies whatever already exists inside a business.
If the economics are sound, growth can create significant value.
If the economics are weak, growth can accelerate the problem.
Revenue Growth Is Not the Same as Profitable Growth (Business Improvement Perth)
Imagine two businesses.
Business A increases revenue by 20%, maintains its gross margin, controls overheads, collects customers promptly and requires little additional working capital.
Business B also grows 20%, but discounts heavily to win work, experiences higher labour costs, carries more stock, extends generous credit terms and borrows to finance the resulting cash shortfall.
The headline growth rate is identical.
The economics are completely different.
Owners should therefore stop asking only:
“How much did we grow?”
They should also ask:
“What did that growth contribute?”
Profitable growth should improve the economic strength of the business.
It should ultimately contribute to cash generation, return on capital and business value.
This is why the disciplines described in the Business Performance Improvement Pyramid matter. Revenue is only one performance lever. Pricing, gross margin, productivity, operating expenses, working capital and capital efficiency all determine whether growth ultimately creates value.
Why EBITDA Does Not Equal Cash (Business Advisor Perth)
EBITDA can be useful.
But EBITDA is not cash.
A company can report positive EBITDA while experiencing severe cash pressure because EBITDA does not tell you what happened to:
- accounts receivable,
- inventory,
- accounts payable,
- capital expenditure,
- loan principal repayments,
- tax payments,
- owner distributions,
- acquisitions, or
- other demands on cash.
Consider a simplified example.
A business reports EBITDA of $800,000.
During the same period:
- debtors increase by $350,000,
- inventory increases by $200,000,
- capital expenditure consumes $150,000,
- loan principal repayments consume $100,000, and
- tax payments consume another $120,000.
The business may appear profitable on the income statement while its cash position deteriorates sharply.
The crucial management question is therefore not simply:
“What is our EBITDA?”
It is:
“How much of our EBITDA actually converts into cash?”
This is also why good KPIs and business forecasting must go beyond sales and accounting profit.
Gross-Margin Leakage, The Silent Profit Killer (Business Improvement Perth)
One of the first places I would look when revenue is rising but cash is deteriorating is gross margin.
Small margin movements have enormous consequences.
Suppose an SME generates $10 million of revenue at a 35% gross margin.
Gross profit is $3.5 million.
If competitive pressure, discounting, labour overruns, supplier increases or poor quoting reduce gross margin to 31%, gross profit falls to $3.1 million.
The business has lost $400,000 of gross profit without losing a single dollar of revenue.
Worse, management may attempt to compensate by chasing even more sales.
This can create a vicious cycle:
More revenue → more activity → more working capital → more operational complexity → more cash required.
Meanwhile, the underlying margin problem remains unresolved.
Margin leakage commonly comes from:
- discounting without understanding contribution margins,
- supplier cost increases not passed through,
- overtime and labour inefficiency,
- poor job costing,
- scope creep,
- rework,
- wastage,
- unprofitable customers,
- freight and logistics costs,
- commissions and incentives, and
- fixed-price contracts priced using outdated assumptions.
A growing business needs margin discipline, not merely sales discipline.
Working Capital, Where Profitable Growth Can Consume Cash (Strategic Planning Perth)
Working capital is often where the growth paradox becomes visible.
When sales increase, businesses frequently need more:
- inventory,
- work in progress,
- labour,
- subcontractors,
- materials, and
- credit extended to customers.
Those costs often need to be funded before the customer pays.
Imagine a business wins a major contract.
It needs to purchase materials today, pay employees fortnightly and meet supplier accounts within 30 days.
The customer pays in 60 or 90 days.
The contract may be profitable.
But somebody has to finance the gap.
Multiply that across rapidly increasing revenue and the cash requirement can become substantial.
This is one reason a robust FY27 business plan and budget should include integrated cash-flow and working-capital forecasts rather than relying on a profit and loss budget alone.
Growth requires funding.
The faster the growth, the more important this becomes.
Debtors, Revenue You Have Earned But Cannot Spend (Business Improvement Perth)
A sale is not cash.
An invoice is not cash.
A debtor is effectively money your business has lent to a customer.
If revenue grows rapidly while debtor days deteriorate, enormous amounts of cash can become trapped in accounts receivable.
Consider a business with annual credit sales of $12 million.
Average sales are roughly $1 million per month.
If average collection moves from 30 days to 60 days, approximately another $1 million may become tied up in debtors, depending on sales patterns and timing.
That can transform an apparently profitable business into one desperately seeking additional funding.
Owners should monitor:
- debtor days,
- ageing by customer,
- overdue accounts,
- disputed invoices,
- concentration among major customers,
- payment-term exceptions, and
- actual collections versus forecast collections.
Strong revenue growth accompanied by worsening debtor days should be treated as a warning signal.
Inventory, Cash Sitting on Shelves (Business Improvement Perth)
Inventory is another common cash trap.
Owners often see inventory as an asset.
Accountants correctly record it as one.
But financially, inventory is also cash that has stopped moving.
Excess inventory can arise from:
- optimistic sales forecasts,
- poor purchasing controls,
- minimum order quantities,
- obsolete stock,
- slow-moving product lines,
- fear of stockouts,
- supplier discounts encouraging over-ordering, and
- weak inventory reporting.
A business may therefore report growing assets while simultaneously experiencing declining liquidity.
Monitor inventory days, stock turns, obsolete stock, slow-moving inventory and gross margin return on inventory.
Ask:
“If we had to convert this stock into cash quickly, how much of its balance-sheet value would we actually recover?”
That question can produce a very different view of liquidity.
The ATO Should Never Become Your Long-Term Bank (Business Advisor Perth)
One of the clearest warning signs of deteriorating cash flow is repeatedly delaying tax obligations.
The ATO’s 2025–26 corporate plan states that collectable tax debt exceeds $50 billion, with approximately two-thirds relating to small business.
That is significant.
GST collected from customers is not operating cash.
PAYG withholding deducted from employees is not operating cash.
Superannuation obligations are not discretionary funding.
When these amounts are repeatedly used to finance operations, the business may be borrowing from tomorrow to survive today.
The economics have also become less forgiving. General interest charge incurred from 1 July 2025 is no longer tax deductible.
The danger is behavioural as much as financial.
An owner delays one BAS payment.
Cash pressure eases temporarily.
Another liability falls due.
That payment is delayed as well.
Soon the ATO balance has effectively become part of the business’s permanent funding structure.
That should trigger immediate investigation into the underlying economics.
Underquoting Can Make Growth Dangerous (Business Improvement Perth)
Not all revenue is good revenue.
This is particularly important in construction, transport, manufacturing, professional services and other businesses where contracts are quoted in advance.
A business may win substantial new work because its pricing is attractive.
Unfortunately, it may be attractive for the wrong reason.
The business has underquoted.
Common causes include:
- outdated labour assumptions,
- underestimated job duration,
- failure to recover overheads,
- inadequate contingencies,
- supplier price increases,
- fuel increases,
- poor scope definition,
- unpriced variations,
- rework,
- optimistic productivity assumptions, and
- fixed-price contracts during periods of cost escalation.
A badly priced $1 million contract does not become a good contract because the sales team wins it.
Sometimes the financially intelligent decision is to walk away from revenue.
Debt Can Hide the Problem, Until It Cannot (Business Advisor Perth)
Borrowing can be entirely appropriate.
Debt can fund productive assets, acquisitions, expansion and temporary working-capital requirements.
But debt becomes dangerous when it repeatedly finances an operating model that does not generate sufficient cash.
The RBA reported average interest rates on outstanding small-business loans of approximately 7.46% in July 2026.
At that rate, leverage has a meaningful cash cost.
Owners should monitor:
- interest cover,
- debt-service coverage,
- leverage,
- loan-to-value ratios where relevant,
- covenant headroom,
- refinancing dates,
- principal repayment obligations,
- security arrangements, and
- personal guarantees.
The warning sign is not necessarily having debt.
It is needing ever-increasing debt simply to maintain normal operations.
My broader guide to funding options for businesses discusses why funding structure should follow business economics and strategy, rather than being used to postpone confronting an underlying problem.
Temporary Illiquidity or a Broken Business Model? (Business Advisor Perth)
This distinction is critical.
A fundamentally sound business can experience temporary cash pressure.
Examples include:
- a major debtor paying late,
- seasonal inventory purchases,
- a large once-off capital expenditure,
- temporary project timing differences,
- rapid but profitable expansion, or
- an unusual short-term disruption.
These situations may justify working-capital finance.
But finance will not repair a structurally broken business model.
Warning signs of a deeper problem include:
- persistently inadequate gross margins,
- structurally unprofitable products or customers,
- permanent reliance on overdue creditors,
- recurring ATO arrears,
- increasing debt despite growing revenue,
- inability to generate positive operating cash across a normal cycle,
- continual equity injections merely to survive, and
- no credible path to sustainable cash generation.
When owners are uncertain which situation they face, the answer is not more optimism.
It is diagnosis.
As I argue in Stop Guessing, Your Business Is Already Telling You What’s Broken, the numbers usually contain the warning signs long before the crisis becomes obvious.
The CASHFLOW Early-Warning Framework for SME Owners & Leaders (Business Improvement Perth)
SME owners need a simple way to identify whether growth is strengthening or weakening their business.
The CASHFLOW Framework provides nine diagnostic lenses.
C — Cash Conversion
Measure how effectively accounting profit converts into operating cash.
Track operating cash flow relative to EBITDA over time.
Ask: Where is the profit going before it reaches the bank?
A — Accounts Receivable
Monitor debtor days, ageing, overdue accounts and customer concentration.
Ask: Are customers effectively using us as their bank?
S — Stock & Work in Progress
Track inventory days, stock turns, obsolete inventory and work-in-progress conversion.
Ask: How much cash is trapped in stock and unfinished work?
H — Headline & Gross Margins
Monitor gross margin by customer, product, service, job and division, not simply at company level.
Ask: Are we growing profitable revenue or merely growing activity?
F — Funding & Debt
Review debt servicing, interest cover, covenants, refinancing requirements and reliance on overdrafts.
Ask: Is debt funding growth, or concealing weak cash generation?
L — Liabilities to the ATO & Other Creditors
Track overdue tax, superannuation, suppliers and payment arrangements.
Ask: Are we financing the business by delaying obligations?
O — Operating Cost Discipline
Review labour productivity, overhead growth, cost escalation, pricing recovery and operating leverage.
Ask: Are costs growing faster than the economic value being created?
W — Working Capital Cycle
Measure debtor days + inventory days − creditor days.
Then monitor the trend.
Ask: How many days does each dollar remain trapped between paying suppliers and receiving customer cash?
! — Warning Signals & Action
The exclamation mark matters.
Measurement without action achieves nothing.
Establish thresholds that automatically trigger investigation.
Examples might include:
- gross margin falling by more than an agreed tolerance,
- debtor days exceeding target,
- overdue ATO obligations,
- cash conversion deteriorating for consecutive months,
- covenant headroom falling below an agreed buffer, or
- forecast minimum cash falling below a Board-approved threshold.
The purpose of CASHFLOW is not simply to report what happened. It is to create an early-warning system before a liquidity problem becomes a solvency problem.
A Simple Monthly SME Cash Dashboard (Governance & Boards)
Every owner, CEO and Board should be able to see at least the following each month:
- revenue versus budget and prior year,
- gross profit percentage,
- EBITDA percentage,
- operating cash flow,
- cash conversion,
- closing cash,
- 13-week cash forecast,
- debtor days,
- debtors over 60 and 90 days,
- inventory days,
- creditor days,
- overdue ATO obligations,
- total borrowings,
- interest cover,
- covenant headroom, and
- forecast minimum cash.
You do not need 100 financial KPIs.
You need the few indicators capable of warning you early enough to act.
Ten Practical Recommendations for SME Owners (Business Improvement Perth)
1. Introduce a rolling 13-week cash-flow forecast.
Update it weekly when liquidity is tight.
2. Measure cash conversion, not EBITDA alone.
Reconcile EBITDA to operating cash and understand every major difference.
3. Review gross margins monthly.
Analyse them by customer, product, service, contract or division.
4. Put debtor collection on the management agenda.
Do not delegate the entire issue to accounts receivable.
5. Establish inventory targets.
Identify obsolete and slow-moving stock and release trapped cash.
6. Ring-fence tax obligations.
Do not treat GST, PAYG withholding and superannuation as free working capital.
7. Stress-test debt servicing.
Model weaker margins, slower collections and higher borrowing costs.
8. Reprice poor work.
Revenue that destroys margin or cash is not worth protecting merely for turnover.
9. Introduce CASHFLOW thresholds into management and Board reporting.
Make exceptions visible and assign responsibility.
10. Seek an independent diagnosis early.
The earlier deteriorating economics are identified, the more strategic options usually remain available.
Key Takeaways (Business Advisor Perth)
- Revenue growth does not automatically create financial strength.
- A business can be profitable on paper and still run out of cash.
- EBITDA must be reconciled to actual cash generation.
- Small reductions in gross margin can destroy large amounts of profit.
- Rapid growth frequently increases working-capital requirements.
- Debtors and inventory can absorb enormous amounts of cash.
- Recurring ATO arrears should be treated as an early-warning indicator.
- Debt can temporarily hide weak cash generation but cannot permanently repair it.
- Owners must distinguish temporary illiquidity from structurally poor business economics.
- A disciplined cash-conversion dashboard can identify deterioration while management still has time to respond.
Frequently Asked Questions (Business Improvement Perth)
Can a profitable business become insolvent?
Yes. Accounting profitability and liquidity are different. A business can report profits but be unable to meet obligations as they fall due because cash is trapped in debtors, inventory or other assets, or consumed by debt repayments, tax, capital expenditure and other commitments.
Why does growth create cash-flow pressure?
Growth frequently requires expenditure before the resulting customer cash is received. Inventory, labour, materials and overheads may need to be funded weeks or months before customers pay.
Why isn’t EBITDA the same as cash?
EBITDA excludes important cash movements including working-capital changes, capital expenditure, tax and loan principal repayments.
What is cash conversion?
Cash conversion measures how effectively accounting earnings translate into actual cash generated by operations.
What is the working-capital cycle?
A useful simplified measure is debtor days plus inventory days minus creditor days. It indicates how long cash is committed to operations before being recovered through customer payments.
Is increasing debt always a warning sign?
No. Debt can sensibly finance productive assets, acquisitions and profitable growth. It becomes concerning when borrowings continually increase simply to support ordinary operations or recurring cash deficits.
Is an ATO payment plan necessarily a sign of financial distress?
Not necessarily. Temporary circumstances can create legitimate short-term cash pressure. Repeatedly relying on overdue tax liabilities to fund normal operations, however, deserves careful investigation.
How often should SMEs forecast cash?
At minimum, businesses should maintain regular cash forecasts. Where liquidity is tight or rapidly changing, a rolling 13-week forecast updated weekly can provide far greater visibility.
Which number should an SME owner watch most closely?
There is no single number. Gross margin, operating cash flow, debtor days, inventory days, cash conversion, tax arrears and debt servicing should be viewed together.
When should an owner seek outside advice?
Ideally before cash becomes critical. Deteriorating margins, increasing debt, recurring tax arrears, worsening debtor days and persistent forecast cash deficits are all reasons to investigate early.
Conclusion, Growth Should Create Cash, Not Consume It (Business Improvement Perth)
There is nothing inherently wrong with rapid growth.
Growth can create scale, market position, profitability, opportunity and substantial shareholder value.
But only when the underlying economics work.
A business that requires progressively more debt, delayed tax payments and stretched creditors simply to support increasing revenue may not be growing stronger.
It may simply be getting bigger while becoming financially weaker.
That is the great SME insolvency paradox.
Do not wait until the bank account tells you there is a problem.
Margins, debtors, inventory, tax liabilities, debt servicing and cash conversion usually start telling the story much earlier.
Learn to read those signals.
Because the most important question is not:
“How fast are we growing?”
It is:
“How much sustainable cash and long-term value is that growth actually creating?”
Call to Action (Business Advisor Perth)
If your revenue is increasing but cash flow, margins, working capital or debt are moving in the wrong direction, the priority is to understand why before simply pursuing more sales or more funding.
An independent review can help identify whether the underlying issue is pricing, margins, working capital, cost structure, debt, financial controls, strategy or the business model itself.
