How do I cover cash flow while customers pay late?

Why does late payment hurt so much?

Because your costs don’t wait. Wages go out weekly or fortnightly. Rent is monthly. Suppliers want paying on their terms, not your customers’. And from 1 July 2026, super is due within seven business days of each payday under Payday Super. When a customer takes 60 days instead of 30, you’re effectively lending them money — interest-free — while you scramble.

Mr’s view: profitable businesses run out of cash all the time. Late payers are one of the main reasons.

Step one: shrink the gap

Before borrowing a cent, make the gap smaller. business.gov.au’s advice on improving cash flow and setting payment terms boils down to a few habits:

• Invoice immediately. Not at month-end. The clock starts when the invoice lands.
• Put payment terms on everything — quotes, contracts, invoices — so there’s no ambiguity.
• Ask for deposits on special orders or large jobs.
• Bill progressively on longer jobs instead of at the end.
• Make paying easy — card, bank transfer, payment links.
• Chase early. A polite reminder the day after the due date, a call a week later, then a formal demand if needed.
• Check new customers’ credit before offering them terms, and set limits.

Even trimming ten days off your average collection time can free up a surprising amount of cash.

Step two: bridge what’s left

Some gap is unavoidable — big customers often dictate terms. That’s where finance earns its keep.

Situation	Suits	Why
Recurring 30–60 day gap every month	Business line of credit	Draw when costs land, repay when customers pay
One big customer is late, once	Short unsecured loan	Defined amount, defined repayment source
Growing fast; debtors growing too	Line of credit sized on turnover	Grows with the business
Large contract with big upfront costs	Term loan or property-secured loan	Bigger amount, structured to the contract

Our page on choosing a line of credit or term loan goes deeper on the first two.

What will a lender want to see?

• Aged debtors list — who owes what, and how overdue.
• Bank statements showing that customers do pay, eventually.
• Your customer concentration — one customer owing most of the money is riskier than twenty owing a little each.
• The contracts or terms with your major customers.
• ATO position — lenders check lodgements whatever the purpose.

An illustrative example

A Perth labour-hire business pays its workers weekly and invoices its two mining-services clients monthly on 45-day terms. That’s up to ten weeks between paying wages and getting paid. A line of credit sized on turnover covers wages; the balance peaks before client payments arrive and falls straight after. Meanwhile, the owner negotiates fortnightly invoicing with one client, cutting the gap — and the amount drawn — noticeably.

When shouldn’t I borrow?

• When the customer is disputing the invoice and may never pay.
• When the customer is insolvent or has stopped responding.
• When late payment is a symptom of pricing too low — you’re financing a loss.
• When the line of credit never comes back down. That’s not a timing gap; it’s a structural shortfall.

In those cases, the conversation is about collections, pricing or restructuring, not borrowing. If pressure is building, the Small Business Debt Helpline (1800 413 828) is free.

How does this connect to tax time?

Late payers often cause BAS shocks, because the GST you owe is calculated on invoices you’ve issued, not money you’ve received (if you account on an accruals basis). If that’s hit you, see borrowing to pay your BAS. And plan for payday super with our guide to payday super and cash flow.

How do I know if late payment is the real problem?

Run a quick test. Take your last three months of invoices and work out the average number of days between sending an invoice and getting paid. Compare it with your stated terms. If you offer 14 days and you’re averaging 41, collections are the problem. If you’re averaging 16 days and still short of cash, the problem is elsewhere — pricing, costs, or how much stock and work-in-progress you’re carrying.

Your accounting software can usually produce an aged receivables report in seconds. Look at it weekly. The customers at the top of the “over 60 days” column are where to start.

Should I offer a discount for paying early?

Sometimes it’s worth it. A small discount for payment within a few days can pull cash forward cheaply, especially from customers who have the money but no reason to hurry. Work out what the discount costs you against what it would cost to borrow the same money for the same period. If the discount is cheaper, it’s a good trade; if not, a line of credit may be the better tool. business.gov.au lists early payment incentives among its suggestions for getting paid faster.

Waiting on customers and bills are due?

Tell Mr about it in about 60 seconds — your monthly turnover, who owes you and roughly when they pay. There’s no credit check to enquire, your details stay with one specialist rather than being circulated to lenders, and a real person will tell you whether a line of credit, a short loan or simply tighter terms is the right move. Accurate turnover and debtor figures make the answer useful. See if you qualify.
