Your business is not going to fail overnight. It will fail slowly, over 12 to 18 months, while the profit and loss still looks fine and you convince yourself things will turn around.
The warning signs are sitting in your accounting software right now. You do not need a finance degree to read them. You need five numbers and five minutes.
To make this concrete, we will follow a single business through all five checks: a Sydney-based services company with $3.2 million in annual revenue, 14 employees, and a founder who thinks things are going well because revenue grew 18% last year. Let's call it what it is: a business that looks healthy on the surface but is quietly bleeding out.
Here is what to check.
Today's bank balance is meaningless on its own. What matters is the direction.
Open your bank account in Xero, or just log into your online banking. Look at your balance on the first of the month for the last 6 months. Write those six numbers down.
If the trend is upward, or flat, your business is generating cash. If the trend is downward, your business is consuming cash, regardless of what the profit and loss says.
Our example business:
November 1: $142,000. December 1: $128,000. January 1: $115,000. February 1: $98,000. March 1: $84,000. April 1: $71,000.
That is a $71,000 decline in six months, averaging roughly $12,000 per month. At that rate, this business runs out of operating cash in approximately six months. But last year's P&L showed $280,000 in profit. The founder has no idea there is a problem.
Why this catches what profit misses: Your P&L shows revenue when earned, not when collected. It shows expenses when incurred, not when paid. It excludes loan repayments, tax payments, owner drawings, and asset purchases. Cash trend captures all of it.
Warning zone: Three or more consecutive months of declining bank balance, unless explained by planned investment or seasonal patterns you can clearly identify.

In Xero, go to Reports, then Accounts Receivable, then Aged Receivables Summary. Look at the total amount in each ageing bucket: current, 1 to 30 days, 31 to 60 days, 61 to 90 days, and 90+ days.
What healthy looks like: 70% or more of receivables are current or under 30 days, less than 10% over 60 days, nothing material over 90 days unless actively in dispute.
What trouble looks like: 30% or more over 30 days, a growing amount in the 60 to 90 day bucket, 90+ day debts that are not being actively chased, or any single debtor representing more than 20% of total receivables.
Our example business:
Total receivables: $410,000. Current: $164,000 (40%). 1 to 30 days overdue: $123,000 (30%). 31 to 60 days: $82,000 (20%). 61 to 90 days: $28,700 (7%). Over 90 days: $12,300 (3%).
Only 40% is current. That is well below the 70% benchmark. And there is a problem hiding in the detail: one client owes $95,000 across the 30 to 60 day buckets. That single debtor represents 23% of total receivables. If that client goes under or disputes the invoices, this business loses a quarter of its outstanding cash.
Why it matters: Every dollar in aged receivables is cash you have earned but cannot spend. At $3.2 million revenue with average debtor days drifting from 38 to 47 over the past year, roughly $60,000 in additional cash is now permanently trapped in unpaid invoices compared to where this business was 12 months ago. That $60,000 is almost exactly the gap between making payroll comfortably and sweating every fortnight.

This is the number most business owners never check until it is too late.
You owe the ATO money right now. GST collected on your sales. PAYG withholding from your employees' wages. Your own PAYG income tax instalments. Super guarantee for your staff. Possibly payroll tax to your state revenue office.
How to check it: Look at your balance sheet in Xero. Find the GST control account (usually called "GST" or "ATO Clearing Account"), the PAYG liability, the superannuation liability, and the provision for income tax (if you have one). Add these up. This is roughly what you owe in tax obligations right now.
Now compare that to your bank balance.
Our example business:
GST owing: $42,000. PAYG withholding: $28,000. Super owing: $24,000. PAYG instalments: $15,000. Estimated payroll tax (NSW): $8,000. Total tax liabilities: $117,000. Bank balance: $71,000.
This business is $46,000 short of covering its tax obligations. The founder sees $71,000 in the bank and thinks things are tight but manageable. In reality, $71,000 of that belongs to the ATO and super funds. The business has negative real cash. It is insolvent and the founder does not know it.
The bigger picture: The ATO is owed over $50 billion, with around $34 billion of that sitting with SMEs. The ATO issued 84,529 Director Penalty Notices in 2024-25, a 136% increase on the prior year. They are not waiting around. And from 1 July 2025, the general interest charge on ATO debt is no longer tax-deductible. For a company paying tax at 25%, this effectively increases the after-tax cost of ATO interest by approximately 33%. The current GIC rate sits at 10.96% for the April to June 2026 quarter, compounding daily.
Best practice: Maintain a separate bank account for tax obligations. When revenue hits your main account, immediately transfer the estimated GST (roughly 1/11th of GST-inclusive revenue), PAYG, and super amounts. This money is not yours. Treat it accordingly.
You do not need to calculate the exact gross margin. You need to know whether it is going up or going down.
In Xero, pull your profit and loss for the last 12 months. Look at the gross profit line (revenue minus cost of goods sold or direct costs). Calculate gross profit as a percentage of revenue for each quarter over the past year.
Our example business:
Q2 FY25 (Oct to Dec 2024): 44%. Q3 FY25 (Jan to Mar 2025): 42%. Q4 FY25 (Apr to Jun 2025): 40%. Q1 FY26 (Jul to Sep 2025): 38%. Q2 FY26 (Oct to Dec 2025): 37%. Q3 FY26 (Jan to Mar 2026): 36%.
That is an 8 percentage point decline over 18 months. On $3.2 million revenue, each percentage point is $32,000. The total margin erosion represents roughly $256,000 in lost profit compared to where the business was sitting 18 months ago. And because revenue grew 18%, the founder thinks things are improving. They are not. The business is working harder for less.
What is causing it in this case: Two things. First, the business hired two junior staff to support the growth, but their utilisation has been running at 55% against a target of 75%. They are being paid but not generating enough billable work to cover their cost. Second, the founder discounted a large contract by 12% to win it from a competitor. That single deal pulled the average margin down across the whole book.
Common causes more broadly: Rising supplier costs not passed on to clients. Scope creep on projects (delivering more than you quoted). Discounting to win work without understanding the margin impact. Staff inefficiency as you hire less experienced people. Mix shift towards lower-margin work.
Why it matters more than revenue: Revenue can grow while margins shrink, and you end up working harder for less profit. A $4 million business at 8% net margin ($320,000 profit) is worse than a $3 million business at 15% net margin ($450,000 profit). Read our article on business pricing strategy for how to fix this.
Warning zone: Two or more consecutive quarters of declining gross margin without a clear, temporary explanation.
Pull your profit and loss for the last 12 months and note the net profit figure. Then check your owner drawings for the same period. In Xero, this appears on the balance sheet under equity, typically called "Owner Drawings" or "Director Drawings." For company directors, include your salary, super, and any dividends paid.
The test is simple: Are your total drawings less than, equal to, or greater than net profit?
Drawings less than profit: The business is retaining cash. Healthy.
Drawings roughly equal to profit: The business is breaking even on a cash basis after paying you. Sustainable, but no buffer.
Drawings greater than profit: You are depleting the business. Every year this continues, the cash reserves shrink and the business becomes more fragile.
Our example business:
Net profit (per P&L): $280,000. Director salary: $180,000. Director super: $21,600. Dividends taken: $95,000. Total owner remuneration: $296,600.
The founder is drawing $16,600 more than the business earns. That seems small, but it has been happening for three years. Over that period, $49,800 has been drained from reserves. Combined with the cash consumption from growing receivables, margin erosion, and the tax liability gap, this is the final piece of the puzzle explaining why the bank balance is dropping by $12,000 per month despite strong revenue growth.
The hard truth: If you cannot pay yourself a reasonable salary from genuine profit, the business either has a margin problem, a revenue problem, or a cost structure problem. Drawing more than you earn is a band-aid that makes the underlying issue worse every month.

Here is what is happening to our example business when you put all five numbers together:
Bank balance trend: Down $71,000 in six months. Debtor ageing: Only 40% current, with $60,000 more trapped in receivables than 12 months ago. Tax liability gap: $46,000 short of covering ATO and super obligations. Gross margin: Declined from 44% to 36% over 18 months, eroding $256,000 in annual profit. Owner drawings: Exceeding net profit by $16,600 per year.
No single number screams "crisis." Together, they paint a picture of a business that will be insolvent within 12 months unless something changes.
The founder thinks revenue growth means things are going well. The P&L shows a profit. The accountant has not raised any alarms because the annual return is not due yet. But the cash is telling a completely different story.
Check each number and score yourself.
Healthy (score 2): Bank trend flat or up for 3+ months. 70%+ of receivables current. Tax liabilities fully covered by cash. Gross margin stable or improving. Drawings below net profit.
Warning (score 1): Bank trend declining for 2 to 3 months. 50 to 70% of receivables current. Tax liabilities within 20% of bank balance. Gross margin declined 1 to 2 points over 2 quarters. Drawings roughly equal to net profit.
Critical (score 0): Bank trend declining for 4+ months. Under 50% of receivables current. Tax liabilities exceed bank balance. Gross margin declined 3+ points over 2 quarters. Drawings exceed net profit.
Total score 8 to 10: Your finances are solid. Keep monitoring monthly.
Total score 5 to 7: You have warning signs. Address the weakest number first and get professional eyes on your cash flow this month.
Total score 0 to 4: This is urgent. You are on a trajectory toward insolvency. Act this week, not this quarter.
If one number is off, it is a problem to address. If two or more are flashing, your business is on a trajectory that leads to insolvency, even if today feels fine.
This week: Calculate all five numbers. Write them down somewhere you will see them monthly. Identify the single biggest problem area. If your tax liability gap is negative (you owe more than you have), that is your number one priority. Contact the ATO proactively about a payment plan before they contact you. The ATO is far more accommodating with businesses that engage early than those that go silent.
This month: Set up a separate bank account for tax provisions and start transferring GST, PAYG, and super amounts the same day revenue lands. Run your debtor ageing report and personally call every client with a balance over 60 days. Review your last three months of new work: did you discount anything? What is the margin on your most recent contracts compared to 12 months ago?
This quarter: Build a 13-week rolling cash flow forecast. Our cash flow forecasting guide walks through the process step by step. Have an honest conversation about owner drawings: if they exceed profit, the draw needs to come down or the business needs to generate more profit. There is no third option.

How often should I check these numbers?
Bank balance trend and debtor ageing: weekly. Tax liability gap: fortnightly, or before every BAS lodgement. Gross margin and owner drawings: monthly. The weekly checks take five minutes. The monthly checks take fifteen. There is no excuse not to do this.
I am not sure how to find these in Xero. Can I just ask my bookkeeper?
Yes. Ask them to prepare a one-page monthly summary showing bank balance trend (first-of-month balances for the last 6 months), debtor ageing summary, tax liabilities vs cash, gross margin percentage by quarter, and total owner drawings vs net profit. Any competent bookkeeper can produce this. If yours cannot, that is a data point in itself.
My bank balance is declining but my P&L shows profit. Is that normal?
It can be explained by growth (investing in stock, equipment, or hiring ahead of revenue), increased debtor days, loan repayments, or excess owner drawings. But "explained" and "healthy" are different things. Understand why, then decide whether the cause is sustainable. Our article on why cash feels tight when profits look fine breaks this down in detail.
What if my drawings have been exceeding profit for years?
This means you have been gradually depleting the business. Check your balance sheet: if retained earnings are negative, the business has less equity than when it started. This requires immediate attention: either increasing profitability or reducing drawings. Our guide on owner pay benchmarks by revenue stage can help you work out what is sustainable.
Is the tax liability gap really that dangerous?
Yes. It is the number one path to insolvency for Australian SMEs. The ATO issued 84,529 Director Penalty Notices in 2024-25, targeting $5.5 billion in liabilities. A DPN creates personal liability for the director. If your combined tax liabilities exceed your bank balance, you are spending money that belongs to the government. Fix this before anything else.
My gross margin dropped but revenue is up. Isn't that just a trade-off?
Sometimes, temporarily. If you deliberately discounted to win a strategic anchor client that will generate referrals, a short-term margin dip can be justified. But margin erosion from scope creep, poor pricing, or underutilised staff is not a trade-off. It is a leak. And leaks get worse, not better. Revenue growth with declining margins is one of the most dangerous patterns in business finance because it feels like progress while the business quietly deteriorates.
Can I use these five numbers to benchmark against other businesses?
These are internal health indicators, not industry benchmarks. A 36% gross margin might be excellent in construction and terrible in consulting. The direction matters more than the absolute number. If your margins are moving in the wrong direction, it is a problem regardless of where they sit relative to industry averages.
What is the single most important number of the five?
The tax liability gap. Everything else gives you time to fix it. A negative tax liability gap, where you owe the ATO more than you have in the bank, is the one that triggers enforcement action, Director Penalty Notices, and potential insolvency. If you only check one number, check this one.
I only have one number in the warning zone. Should I still be concerned?
Keep monitoring. One warning sign is a problem to watch. But these five numbers tend to move together: declining margins reduce profit, which makes drawings harder to sustain, which drains cash, which leads to spending tax provisions. Catching the first domino early is the whole point.
How many months of cash runway should my business have?
Three to six months of fixed operating costs is the standard benchmark. For our example business with roughly $180,000 in monthly fixed costs, a healthy buffer is $540,000 to $1,080,000. Having $71,000 (with $117,000 in tax owed) is not a buffer. It is a countdown. Read our full guide on how many months of cash runway your business has.
