When a big customer pays late: bridging the gap without panic

Why does one late payer cause so much damage?

Because your obligations don’t move when theirs do. Payroll still lands on Thursday. The supplier still expects payment on the 30th. The BAS still has a due date. If a customer who makes up a large share of your revenue pays three weeks late, you can go from comfortable to short in a single invoice cycle — through no fault of your own.

The worst outcome isn’t the delay itself. It’s the chain reaction: you pay a supplier late, they tighten your terms, you miss super, the ATO adds interest, staff get nervous. Funding the gap breaks the chain.

Fast options while you wait

What you need	Capital source	Speed
Cash against the late invoice itself	Invoice finance	Days to set up the first time (general market guide)
A small, fast top-up	Unsecured loan	Same day possible for smaller amounts
A recurring buffer	Line of credit	Quick draws once open
A large amount, urgently	Caveat loan or second mortgage	$20k–$250k possible same day

If payroll is the immediate pressure, see payroll and super.

Chasing the money — firmly and fast

While capital buys you time, keep the pressure on the debtor:

1. Check the basics. Is the invoice correct, sent to the right person, matching their purchase order?
2. Call, don’t just email. Find out who approves payments and what’s holding it up.
3. Put it in writing. Confirm the conversation and the promised date.
4. Escalate politely. Contact a more senior person if dates slip.
5. Know your options. Many contracts allow you to suspend work for non-payment. For construction work, state security of payment laws may give you formal rights.

Most late payments are process problems, not money problems — an invoice stuck in someone’s inbox. A phone call often fixes them faster than any letter.

Can you finance the late invoice itself?

Sometimes. Invoice financiers look at:

• who the customer is — a large, reliable business or government agency is easier to fund
• why it’s late — slow processing is fine; a dispute about the work is a problem
• how late — slightly overdue is often acceptable; very old invoices usually aren’t

If the invoice is disputed, other lanes — unsecured or property-secured — are more practical.

An illustrative example

An events production company invoices a corporate client $96,000 after a conference. The client’s terms are 30 days, but at day 45 the invoice is still unpaid because of an internal approval backlog. Crew wages of $28,000 and an equipment hire bill of $19,000 are due within a week. A short unsecured loan of $50,000, funded the same day, covers both. The client pays at day 58, and the loan is repaid early. The company then sets up an invoice finance facility for future corporate events. (Illustrative only.)

Reduce your exposure next time

• Spread revenue. If one customer is more than a third of turnover, any delay is dangerous.
• Tighten terms. Shorter terms, deposits for large jobs, progress billing.
• Invoice promptly. Every day you wait to invoice is a day added to the gap.
• Keep a standing buffer. A line of credit or invoice facility in place before you need it.

When a late payment becomes a bad debt

Most late payments are eventually paid. Some aren’t. Warning signs that a customer may be in real trouble:

• repeated promises of payment that don’t arrive
• requests to pay in small instalments
• staff leaving, or difficulty reaching the decision-maker
• other suppliers mentioning they’re also owed money
• public notices about administration or liquidation

If you see these, act quickly: stop further credit, document everything, and get advice on your recovery options. Don’t fund a bad debt with long-term borrowing — fund the short-term gap, then adjust your business for the lost revenue.

Concentration risk

If one customer accounts for a large share of revenue, any delay hits hard. Track the share each of your top five customers represents. If one is above a third, consider:

• diversifying your customer base deliberately
• shorter terms or deposits for the biggest accounts
• an invoice finance facility that turns their invoices into cash as they’re issued
• trade credit insurance for large exposures

Payment terms that protect you

Clear terms reduce late payments before they start: payment due dates on every invoice, late-payment terms agreed in contracts, deposits on custom work, and progress billing for longer jobs. Simple, consistent follow-up — a reminder before the due date, a call on the day — is often more effective than any letter after the fact.

Waiting on a payment that should have arrived?

You did the work — the cash flow problem shouldn’t fall on you alone. Asking what could land doesn’t involve a credit check, and your details stay with one specialist rather than being pushed to multiple lenders. A real person will call you. Give us accurate details of the amount owed, who owes it and what’s due on your side, so we can recommend the fastest sensible fix. See if your business qualifies.
