Quick answer
To bridge a business cash flow gap, first measure it with a simple 13-week forecast, then pull the free levers: chase overdue invoices, renegotiate supplier terms, clear slow stock and talk early to anyone you'll pay late, including the ATO. For what remains, choose a facility that matches the gap's shape: a line of credit for recurring gaps, invoice finance for slow payers, or a short-term loan for a one-off.
Key points
- Measure the gap with a 13-week cash flow forecast.
- Pull free levers first: collections, supplier terms, stock.
- Talk early to creditors, including the ATO.
- Match the facility to the gap's shape.
- Fix the cause so the gap doesn't keep returning.
Profit isn’t the same as cash
A business can be profitable and still run out of money. The profit and loss statement records income when it’s earned and costs when they’re incurred. The bank account records money when it actually moves. If you pay suppliers and staff before customers pay you, there’s a gap, and that gap is where many good businesses get into trouble.
Before you go looking for finance, it pays to understand the gap properly. Sometimes it’s smaller than it feels. Sometimes it’s bigger. Either way, knowing its shape tells you exactly what kind of help you need.
Step 1: Measure the gap with a 13-week forecast
A 13-week cash flow forecast is a simple table: weeks across the top, cash in and cash out down the side. business.gov.au has a free template linked below. Fill it in with:
- Cash in: expected customer payments (be realistic about who pays late), other income, GST refunds.
- Cash out: wages and super, suppliers, rent, loan repayments, BAS and PAYG, insurance, other bills.
- Opening balance: what’s in the account now.
The running balance shows you three things: when the gap opens, how deep it gets and when it closes. That’s the information every lender, and every sensible decision, depends on.
Step 2: Pull the free levers first
Before borrowing, see how much of the gap you can close yourself.
| Lever | What to do |
|---|---|
| Collections | Chase every overdue invoice this week. Call, don’t just email. |
| Invoicing | Invoice the day work is finished, not at month end. |
| Terms | Shorten your payment terms for new customers; ask for deposits on big jobs. |
| Suppliers | Ask key suppliers for longer terms or a staged payment. |
| Stock | Clear slow-moving stock, even at a small discount. |
| Spending | Delay non-essential purchases until after the gap closes. |
| Creditors | Talk early to anyone you might pay late. Surprises damage trust; conversations build it. |
Re-run the forecast after pulling these levers. Often the gap shrinks by more than owners expect.
Step 3: Deal with the tax side properly
Tax is a common pressure point. BAS, PAYG withholding and super all land at fixed times, and since Payday Super started on 1 July 2026, super now moves with every payday rather than quarterly.
Always lodge on time, even if you can’t pay in full. If you need time, the ATO’s payment plan options are worth checking: businesses owing $200,000 or less can often set one up online. Keep in mind that general interest charge incurred from 1 July 2025 is no longer tax deductible, so a long-running ATO balance costs more than it used to. If the tax position is a major part of the gap, read ATO debt loans.
Step 4: Match the facility to the gap’s shape
Whatever’s left after the free levers, choose finance that fits the shape of the gap:
| Gap shape | Best fit |
|---|---|
| Repeats every month | Business line of credit |
| Caused by slow-paying business customers | Invoice finance or debtor finance |
| One-off, closes within months | Short-term business loan |
| Seasonal | Seasonal business loan |
| Large, with property available | Short-term property-secured loan |
| Wages before payment | Payroll funding |
The wrong shape costs money. A lump-sum loan for a recurring gap means paying interest on money that sits idle half the month. A revolving facility for a one-off need may come with ongoing fees you don’t need.
If you’d like help reading your forecast and picking the right shape, you can send us an enquiry at any point in this process.
Step 5: Size it from the forecast
Your forecast tells you the deepest point of the gap. Size the facility to that point, plus a buffer of a few weeks’ costs. Then check repayments against the forecast too: they should fit comfortably in the weeks after the gap closes.
Step 6: Fix the cause
A one-off gap is just timing. A gap that keeps returning is a signal. Common causes:
- Pricing that doesn’t cover the true cost of the work.
- Payment terms that are longer than your costs allow.
- Growth that’s faster than your working capital.
- One big customer who pays slowly and dominates your ledger.
- Stock that sits too long.
Talk to your accountant about the cause, not just the symptom. Finance can carry you while you fix it, but it shouldn’t become a permanent crutch.
An illustrative example
A florist’s forecast shows a gap opening in late January, after the Christmas rush, deepening through February and closing in the lead-up to Valentine’s Day and Mother’s Day. Chasing two overdue corporate invoices and agreeing longer terms with the main grower closes half of it. A modest line of credit, drawn in February and repaid by May, covers the rest. (Illustrative only.)
Warning signs to act on now
- You’re regularly paying bills late.
- You’re using the ATO as an informal lender.
- You’re borrowing to make repayments on other loans.
- Your forecast shows the gap getting deeper every month.
If any of these apply, get advice from your accountant. business.gov.au also has resources on managing business debt.
Building your 13-week forecast: a worked layout
If you’ve never built a forecast, start with this simple layout and fill it in from your accounting software and bank statements.
| Row | What goes in it |
|---|---|
| Opening cash | Balance at the start of the week |
| Customer receipts | Only what you genuinely expect to arrive that week |
| Other receipts | GST refunds, asset sales, owner contributions |
| Wages and super | Every payday, now with super alongside |
| Suppliers | By due date, not invoice date |
| Rent, insurance, subscriptions | Fixed commitments |
| Loan repayments | Every existing facility |
| BAS and PAYG | On their due dates |
| Closing cash | Opening plus receipts minus payments |
Three habits make forecasts useful rather than decorative. First, be pessimistic about receipts: if a customer usually pays ten days late, forecast it ten days late. Second, update it every week, replacing forecast figures with actuals. Third, look at the lowest closing balance across all thirteen weeks — that single number, plus a buffer, is the size of the facility you may need.
Once a forecast exists, conversations with lenders, suppliers and the ATO change. Instead of saying “things are tight”, you can say exactly when the gap opens, how deep it gets and when it closes. That precision builds confidence and usually leads to better outcomes on every front. Keep a copy of each week’s version too, so you can see how accurate your predictions were and improve them over time.
Close the gap, keep the business moving
Once you know the size and shape of your gap, finding the right facility is much simpler. The enquiry takes about 60 seconds, there’s no credit check when you enquire, and it’s read by a specialist who works on it personally rather than spreading it to a list of lenders.

Frequently asked questions
What's a 13-week cash flow forecast?
A week-by-week table of the cash you expect in and out over the next quarter. It shows when the gap opens, how deep it gets and when it closes.
Should I borrow to cover a cash flow gap?
Sometimes. Borrowing makes sense when the gap is temporary and the money coming in will repay it. If the gap comes from ongoing losses, fix the cause first.
Can I delay paying the ATO?
Lodge on time regardless. If you can't pay in full, contact the ATO about a payment plan, or consider funding options. Ignoring tax debts makes them more expensive.
What's the quickest way to improve cash flow without borrowing?
Chase overdue invoices and invoice immediately when work is done. It's free and often surprisingly effective.
