You look at the P&L and the business is profitable. You look at the bank account and the cash isn't there. Both are accurate. Both describe the same business. And yet they tell two completely different stories.
It's the question every owner asks at some point: why doesn't my profit equal my bank balance?
It's not an accounting mistake. It's how the numbers actually work. Once you see it, you stop being surprised by it.
Why the P&L doesn't tell you about cash
The P&L records revenue when you earn it and expenses when you incur them. It tells you whether the business made a profit over a period. It does not tell you when the money moved in or out.
That gap is bigger than it sounds.
You can invoice a customer in May, book the revenue in May, and watch the profit show up in May. The cash from that invoice might not arrive until July. The P&L doesn't care. It's already counted the sale.
Most owners only ever look at the P&L. The cash story plays out alongside it, in the timing of money in and money out. That timing is what you feel in the bank account.
Where the cash actually goes
The cash that doesn't show up in your bank balance is sitting somewhere. The usual places:
- Stock or inventory you've paid for but haven't sold yet
- Debtors, money customers owe you but haven't paid
- GST, PAYG, and income tax obligations owed against the business
- Capital expenditure, equipment, fit-outs, software you've already outlaid for
- Owner drawings and loan repayments going out of the business each month
Profit on the P&L can be tied up in any of these. None of them spend like cash in the bank.
How the lag plays out in practice
Here's how the timing actually plays out in a typical month.
You make a $100,000 sale in May. Solid month, profit on the P&L. The invoice goes out with 30-day terms. On paper, May looks strong. The bank account tells a slower story.
| Timing | What the P&L shows | What the bank account does |
|---|---|---|
| May | $100,000 revenue booked, profit recorded | Nothing in yet. The invoice has only just gone out |
| May–June | No change, the sale is already counted | Wages run fortnightly, suppliers want their 30 days, the BAS and PAYG fall due, the equipment repayment goes out |
| Late June / July | Still no change | The $100,000 finally lands |
Your customer is meant to pay in June. In reality, most pay closer to late June or July. Most owners haven't run the analysis on their accounts receivable: the terms say 30 days, the behaviour averages 50 to 60. Common, and rarely surfaced until cash gets tight.
You're paying everyone else before the cash from May actually lands. That's the point where profit and cash come apart.
Can a profitable business run out of cash?
Yes. And the ones growing fastest are the most exposed.
Growth consumes cash before it produces it. A bigger month means more stock bought up front, more wages paid before the work is invoiced, and a larger debtor book waiting to be collected. The sale is booked as profit straight away. The cash to fund all of that activity goes out first and comes back later.
So the business can be profitable on every measure the P&L tracks and still be short of money in the account. It isn't a sign something is broken. It's what happens when a business grows faster than its cash cycle can keep up. The profit is real. It's just tied up in the work that created it.
The levers that close the gap
Seeing the gap is one thing. Closing it is another. It starts with the numbers being right, then a handful of levers do most of the work:
- Accurate bookkeeping and financial records. Everything else here depends on this. If the books are behind or the records are messy, the cash position you're working from is a guess. Clean, current bookkeeping and proper financial management mean the numbers you're reviewing are actually correct. That's the starting point, not an afterthought.
- Debtor days. The single biggest one for most businesses. If your terms say 30 days and customers pay in 55, that fortnight of revenue is funding their business instead of yours. Tighter follow-up and clearer terms pull cash forward without selling a single extra dollar.
- Payment terms, both ways. What you offer customers and what you negotiate with suppliers. Getting paid faster and paying on terms that match your cycle changes the shape of every month.
- Stock and inventory. Cash sitting on shelves is still cash. Carrying less of it, or turning it over faster, frees money that's doing nothing.
- Tax set aside. GST, PAYG, and income tax instalments are owed whether or not the money is sitting there when they fall due. Provisioning for them as you go turns a quarterly shock into a non-event.
- Debt funding. Used well, debt smooths the working capital fluctuations that come with a trading cycle or a growth run. A facility sized to bridge the gap between paying for the work and getting paid for it can be the difference between a tight month and a stalled one. The point is to fund the cycle deliberately, not to discover the shortfall when it hits.
- Owner drawings. There's a difference between taking a market salary for the role you do and pulling cash out whenever it's there. Drawings sized against a proper wage for your role, and against what the business can actually carry, keep the owner's needs and the business's cash from working against each other.
The forecast tells you what's coming. The work on these levers changes it.
Forecast cash, not just profit
The fix is to look forward at cash the same way you look back at profit.
For some businesses, a 13-week rolling forecast does the job. One quarter of operational visibility, updated weekly, showing money in and money out across receivables, payables, payroll, tax, and debt. You see the next pinch point weeks before it arrives.
Other businesses need a longer horizon. If you're scaling, raising debt, planning capex, or running a longer sales cycle, a 6 to 12 month cash flow forecast gives you the runway to make decisions in time. The right cadence depends on size, complexity, and how far ahead the big calls sit.
A forecast won't collect a single invoice on its own. What it does is take the surprise out of the month. That's where the work shifts from forecasting to advisory: tightening terms, sharpening receivables follow-up, renegotiating with suppliers, structuring debt to match the trading cycle.
A starting point
If your numbers say one thing and your bank account says another, you don't need a bigger profit. You need a forward view of your cash, and a plan for closing the gap.
That's the work the forecasting service covers as standard: building the cash model, updating it, and using it to inform the calls you're already making, alongside the broader advisory work that improves the underlying flow.

Common questions
Why is my profit higher than my bank balance? Profit is recorded when you earn it, not when the cash arrives. The difference sits in unpaid invoices, stock, tax owing, equipment you've paid for, and drawings or loan repayments going out each month.
Is profit the same as cash flow? No. Profit measures whether you made money over a period. Cash flow measures when money actually moves. A business can be profitable and short of cash at the same time.
Can a profitable business run out of cash? Yes, and growing businesses are most at risk. Growth ties money up in stock and unpaid invoices while wages, suppliers, and tax still need paying on time.
How do I improve my cash flow? Tighten debtor days, set and enforce payment terms, keep stock lean, set aside for BAS, PAYG, and income tax as you go, and structure debt to match your trading cycle.
What is a cash flow forecast? A forward view of money in and money out over a set period, often a 13-week rolling view, or 6 to 12 months for bigger decisions. It shows the next pinch point before it arrives.
