Quick answer
When customers pay late, tighten the basics first: clear payment terms on every invoice, invoicing as soon as work is done, early-payment incentives or deposits, and prompt, escalating follow-up. Check how large customers report paying suppliers on the Payment Times Reports Register. If a gap remains, invoice finance providers fund business-to-business invoices directly; lines of credit or short-term loans suit other cases.
Key points
- Fix terms, invoicing speed and follow-up before you borrow.
- The Payment Times Reports Register shows how quickly large businesses report paying suppliers.
- Invoice finance grows with your sales and suits B2B businesses with reliable customers.
- Borrowing can't fix a customer who never pays — or a margin problem.
Late payment is the cash flow problem that profitable businesses get. The work is done, the margin is fine, the invoice is out — and the money sits in someone else’s bank account for another month while you cover wages, suppliers and the BAS. Before reaching for finance, it’s worth working through the problem in order. Some of the fixes cost nothing. And if a lender is still needed, knowing exactly what’s causing the gap points you to the right one.
Is it a timing problem or a collection problem?
Start by sorting your overdue invoices into two piles:
- Slow but sure. Customers who always pay, just later than you’d like. This is a timing problem, and finance can help.
- Doubtful. Customers who are disputing, making excuses or going quiet. This is a collection problem, and finance can make it worse by masking it.
Run an aged debtors report from your accounting software. If most of the overdue balance sits with reliable customers paying at 45 or 60 days on 30-day terms, you’re in the first pile.
What can you fix yourself first?
business.gov.au’s guidance on payment terms and cash flow lines up with what lenders like to see before they fund a debtor book.
Set clear terms. Payment terms are the rules for how and when customers must pay. business.gov.au gives 7, 14, 21 or 31 days as examples. Put them on every invoice and in your contracts or quotes.
Invoice immediately. Using accounting software to automate invoicing and send invoices earlier is one of business.gov.au’s first suggestions. A job finished on the 3rd and invoiced on the 28th has lost almost a month.
Ask for money earlier. Deposits for special orders, progress payments on longer jobs and upfront payment for new customers all shrink the gap.
Reward and penalise. business.gov.au suggests early-payment discounts and late fees. Set them out in your terms before the work starts.
Follow up consistently. Start with a polite reminder by phone or email, then escalate to a formal letter of demand or a collection service if needed, as business.gov.au outlines. A diary note for day 1, day 7 and day 14 past due does a lot of the work.
Make paying easy. Offer the payment methods your customers actually use.
Protect the payment itself. Scamwatch warns businesses about invoice and payment redirection scams, where criminals alter payee details on genuine invoices. Tell customers you’ll never change bank details by email, and ask them to verify any change by phone.
How do you check how a large customer pays?
The Payment Times Reporting Scheme aims to improve payment times for small businesses by publishing how quickly large businesses report paying their suppliers. On the Payment Times Reports Register you can search and compare reports and industry statistics. It’s useful in two ways:
- Before you take on a big customer, you can see what payment times to expect and price or plan accordingly.
- When you talk to a lender, you can show that a slow payer is slow by habit, not because of a dispute.
When does it make sense to borrow against the gap?
When the gap is a timing problem with reliable customers, it’s recurring or growing, and the cost of finance in dollars is less than the cost of the gap — missed supplier discounts, stretched wages, late BAS payments or turned-down work.
Unsure whether your debtor book would interest a lender? Ask a specialist — there’s no credit check to ask.
Which lender types fund slow-paying customers?
| Lender type | How it works | Best for |
|---|---|---|
| Invoice finance providers | Advance against invoices as they’re raised | B2B businesses with creditworthy customers on terms |
| Lines of credit (bank, non-bank, online) | Draw when needed, repay when customers pay | Recurring but modest gaps |
| Online lenders | Short-term loan from bank data | One-off squeeze with steady turnover |
| Trade finance providers | Pay your suppliers up front | Gaps that start on the supply side |
| Property-backed lenders | Larger, longer facilities | Big, persistent gaps |
Invoice finance is the most direct fit, because it grows as your sales grow and is secured by the invoices themselves. Providers check your customers as much as you: their reliability, how concentrated your ledger is, disputes and ageing. It works only for invoices to businesses or government, not consumers.
A line of credit is simpler if the gap is modest and predictable. It’s sized on your overall business rather than your debtors, so it won’t grow automatically with sales.

What should you avoid?
- Stacking short-term loans to cover each month’s gap. Daily or weekly debits pile up quickly.
- Funding a doubtful debtor. If a customer may never pay, borrowing against their invoice only adds cost.
- Ignoring margins. If jobs barely break even, faster cash doesn’t help. Fix pricing first.
- Letting tax slip. Late-paying customers are a common reason BAS goes unpaid. A building ATO debt narrows your lender options later.
An illustrative example
Purely illustrative, with no real business involved: a commercial cleaning contractor invoices large property managers on 30-day terms but is routinely paid at 55–65 days. Wages are weekly. The owner starts invoicing on the day each month’s service ends instead of a week later, adds clear terms and a reminder schedule, and checks the Payment Times register before quoting a new large client. The gap shrinks but doesn’t disappear as the business wins more contracts, so the owner sets up an invoice finance facility that releases most of each invoice’s value within days. As the contractor grows, the facility grows with it.
How do lenders view your debtor book?
When you approach a lender, bring:
- an aged debtors report and an aged creditors report;
- a list of your largest customers, their terms and typical payment times;
- sample invoices and any customer contracts;
- recent bank statements and BAS;
- an explanation of any disputed or very old invoices.
A clean, well-managed ledger with reliable customers is an asset lenders are happy to fund.
How do you talk to a slow-paying customer without losing them?
Most late payment isn’t malice; it’s process. A large customer’s accounts team pays on its own cycle, and your invoice may have missed a cut-off or be missing a purchase order number. Before escalating:
- Find the right person. Ask who processes supplier invoices and what they need on an invoice to pay it first time.
- Fix the paperwork. Purchase order numbers, correct entity names and ABNs, and delivery evidence all speed payment.
- Ask about their payment run. If they pay on the 15th and the 30th, time your invoices to land just before.
- Agree on terms in writing for future work, and refer to them when you follow up.
- Escalate politely. If a payment is well overdue, a call to the person who engaged you often moves faster than another email to accounts.
When is a customer too slow to keep?
When the cost of waiting — in finance fees, stretched suppliers and your own time chasing — outweighs the margin on their work. Run the numbers for your slowest customers. Some will be worth keeping on revised terms, with deposits or progress billing. Others may be worth replacing, especially if the Payment Times register suggests the delay is their habit rather than a one-off.
Customers paying slowly and squeezing your cash?
Fix what you can, then let the right lender bridge the rest. Send a 60-second enquiry with who you invoice, your usual terms and how much is outstanding, and a lending specialist will tell you whether invoice finance, a line of credit or another option fits. There’s no credit check to ask, your details aren’t spread across a list of providers, and accurate answers about your debtors help us choose the right facility first time.
Frequently asked questions
What are normal payment terms in Australia?
business.gov.au gives examples such as 7, 14, 21 or 31 days. Large customers often set their own terms. Whatever you agree, put the terms clearly on every invoice and in your contracts.
How can I check whether a big customer pays on time?
The Payment Times Reports Register lets you search payment times reports and industry statistics, showing how quickly large reporting entities say they pay their small business suppliers.
Is invoice finance worth it for late payers?
It can be, if your customers are creditworthy businesses that pay eventually and the cost in dollars is less than the cost of the cash gap. It isn't a fix for customers who don't pay at all.
Should I charge late fees?
business.gov.au suggests early-payment discounts and late fees as ways to encourage prompt payment. Make sure any late fee is set out in your terms before the work is done.
When should I use a debt collector?
business.gov.au suggests starting with a polite reminder, then escalating to a formal letter of demand or a debt collection service if needed. Weigh the cost and the customer relationship.
