Quick answer
When a customer pays late, a short cash flow loan or a draw on a line of credit can cover the bills until their payment lands, with same-day funding possible for smaller amounts once the file is complete. Size it to the gap, not the whole invoice. If late payment is regular, invoice finance, a credit line or tighter terms fix it better than repeated short loans.
Key points
- Size the loan to the gap, not the full overdue invoice.
- A line of credit suits late payers who are regular.
- Have the overdue invoices and payment history ready.
- Chase the payment in parallel; it is your repayment.
- Typical route
- Cash flow loan or line of credit
- Have ready
- Overdue invoices, customer history, statements
- Repaid from
- The late payment
- Speed
- Same-day funding possible for smaller amounts
You did the work, sent the invoice and planned around being paid on day 30. Day 30 has come and gone. Now it’s day 45, the customer’s accounts team “is processing it”, and your own bills are due on Friday. A late payer can put a perfectly healthy business into a cash squeeze in a matter of days.
Fast funding can bridge that gap. The trick is to bridge the gap, not the whole invoice, and to fix the pattern if it keeps happening.
Size the loan to the gap
The overdue invoice might be $80,000, but that’s rarely what you need to borrow. What you need is enough to get through until it’s paid:
| What’s due before the customer pays | Example |
|---|---|
| Wages, PAYG and super | Next pay run |
| Rent | Due on the first |
| Key suppliers | Those who’ll stop supplying if not paid |
| BAS instalment | If it falls in the window |
| A buffer | A week or two in case the payment slips again |
Add those up and you’ll often find the real gap is a fraction of the invoice. Borrowing less means paying less, and fast money costs more than slow money.
How fast it can move
Late-payment gaps suit a cash flow loan or a short unsecured loan. With online banking linked, ID ready and the overdue invoice to show, same-day funding is possible for smaller amounts once the file is complete. If you already have a line of credit, this is exactly what it’s for: draw what you need now, repay when the payment lands.
What to have ready
- The overdue invoices, with dates and amounts.
- The customer’s payment history: have they paid late before, and how late?
- Any written confirmation from the customer about when they’ll pay.
- Linked bank statements and ID for each director.
- A list of the bills you need to cover.
Chase the payment at the same time
Your repayment is the late payment, so keep chasing it. Polite, firm and regular contact with the customer’s accounts team, a copy of the invoice and terms, and a named person to follow up with all help. For larger debts, check your contract’s dispute and interest clauses. If a big business is the late payer, the Payment Times Reporting Regulator publishes how quickly large businesses pay small suppliers, which is useful context when you push for payment.
An illustrative example
A Perth electrical contractor is owed $86,000 by a builder on a completed stage, now 20 days overdue. Wages of $28,000 and a $9,000 wholesaler account are due within the week. The builder confirms in writing that payment will be made in about three weeks. The contractor takes a short cash flow loan of $40,000, covering wages, the wholesaler and a buffer, and repays it when the builder pays. The rest of the invoice lands as profit, not debt. Illustrative only.
When late payment is the norm
If every month brings another late payer, a series of short loans becomes expensive and starts to look like stacking. Better long-term fixes include:
- A line of credit sized to your typical gap, drawn and repaid as invoices land.
- Invoice finance, which advances a share of unpaid invoices and is repaid as customers pay.
- Shorter terms or deposits on new work, especially with customers who’ve paid late before.
- Progress billing on longer jobs, so you’re never waiting on one big invoice.
- Credit checks on new customers before extending terms.
Talking to your own creditors
While you wait, a quick call to your own suppliers or landlord can buy time too. Many will accept a short delay or a part-payment if you explain that a customer is late and show when the money is due. That can shrink the gap you need to fund, or remove it. Just make sure any arrangement is in writing and that you stick to it, because breaking a promise to a supplier mid-crunch costs more goodwill than the original delay.
Keep the ATO in mind as well. If a BAS falls due while you’re waiting to be paid, lodge it on time even if you can’t pay the full amount, and ask about a short payment arrangement. Lodging on time keeps your options open with lenders.
If the customer may not pay at all
If there’s a real risk the customer won’t pay, be careful about borrowing against the payment. Ask for advice early, look at your contract, and consider whether a smaller loan or a payment plan with your own creditors is safer. Small business dispute resolution services can help with larger amounts.

Frequently asked questions
Should I borrow the whole invoice amount?
Usually not. Work out what you actually need to cover until the payment arrives, such as wages, rent and supplier bills. That's often much less than the invoice.
What is invoice finance?
A facility that advances a share of your unpaid invoices and is repaid when customers pay. It suits businesses that regularly wait on large invoices.
What if the customer never pays?
Then the loan still has to be repaid from somewhere else. That's why lenders look at the customer, and why you should chase the debt and consider small business dispute options early.
Can I charge interest on late invoices?
Only if your terms say so and they're fair. Review your contracts and invoice terms, and get advice if a large debt is in dispute.
