How to manage slow-paying customers without losing them

A slow-paying customer rarely announces itself. The work gets done, the invoice goes out, and thirty days later the money simply isn’t there. Nobody has refused anything. You just find yourself paying wages, rent and suppliers on time while someone else holds your cash.

The good news is that most late payment responds to process rather than confrontation. Owners who get paid reliably usually haven’t found nicer customers. They’ve made it easy to pay, awkward to forget, and clear what happens next when an invoice slips. This guide sets out that system, then covers what to do while it takes effect.

Why do customers pay late in the first place?

It helps to separate the reasons, because each one needs a different fix.

Reason	What it looks like	What actually fixes it
Friction	Invoice lost in an inbox, wrong contact, missing purchase order number	Better invoicing: right person, right reference, same-day delivery
Their process	Big company pays on a fixed monthly run, or needs three approvals	Learn their cycle and invoice to hit it
Their cash flow	Small customer stretching you because they’re stretched	Deposits, shorter terms, smaller exposure
A dispute they haven’t voiced	Silence after a job they weren’t happy with	A direct phone call to surface the problem
Habit	Pays late because nobody has ever minded	A consistent reminder ladder, every time

Notice that only one of those five is a customer who can’t pay. The other four are fixable from your side of the desk.

What do large companies actually pay?

There’s a public dataset most small business owners have never opened. Under the Payment Times Reporting Scheme, businesses with annual income over $100 million must report twice a year on how they pay small business suppliers: the terms they offer, how long invoices actually take, and what share are paid on time. The reports sit on the Payment Times Reports Register, searchable by company name.

In its August 2026 report on the second half of 2025, the regulator said 69.8 per cent of small business invoices from reporting entities were paid within 30 days. That’s an improvement of 6.6 percentage points since the scheme began, but it still means roughly three in ten invoices took longer. The same update noted a Fast Small Business Payer List, launched in February 2026, which recognised 96 entities that pay small suppliers within 20 days or less.

Two practical uses for this:

1. Before you sign a big contract, look the customer up. If their reports show long terms or slow real payment, build that into your price and your cash plan rather than discovering it later.
2. When you negotiate terms, you can point to their own published figures. “Your report shows most small suppliers are paid in under 30 days, so we’d like 30-day terms” is hard to argue with.

Government customers have their own commitments too. Non-corporate Commonwealth entities are expected to settle eligible invoices inside 20 calendar days (five for e-invoices), and NSW has a faster payment policy for registered small business suppliers. If you supply government and invoices are sitting longer than that, ask the agency’s accounts team which policy applies.

Set the terms before the work starts

The cheapest moment to prevent a late payment is before you’ve done anything. Business.gov.au suggests your terms should spell out the payment methods you accept, when payment is due, whether you extend credit and on what conditions, and how overdue amounts are handled. Put all of that in the quote and get it accepted in writing.

A few details make a large difference:

• Use a due date, not a term. “Due 14 November” is clearer than “14 days” and removes any argument about when the clock started.
• Ask for a deposit on new or large jobs. A deposit covers your materials and tests the customer’s willingness to pay before you’re exposed.
• Bill in stages. On longer jobs, progress claims at set milestones mean you’re never carrying the whole contract value at once.
• Agree late fees in advance. A fee or interest charge on overdue amounts only works if it was in the terms the customer accepted.
• Keep ownership until paid. If you supply goods, a retention of title clause, properly registered, protects you if the customer gets into trouble.

Make the invoice impossible to ignore

A surprising share of late invoices were never seen by the person who pays them. Before you chase anyone, check that your invoicing does these things:

• Goes out the same day the job is finished or the goods are delivered, rather than in a monthly batch.
• Is addressed to accounts payable, not just the site manager who ordered the work.
• Quotes the customer’s purchase order or job number, because many larger businesses can’t pay without it.
• Shows the due date in large type near the total.
• Offers at least two easy ways to pay, ideally including a pay-now link.

If your accounting software lets customers pay straight from the emailed invoice, switch it on. Every step you remove between “I should pay that” and “paid” shortens the wait.

Build a reminder ladder and stick to it

Most owners chase late payers inconsistently: nothing for weeks, then a frustrated email when the bank balance gets tight. A fixed ladder removes the emotion and the guesswork. Write it down, put the steps in your calendar or software, and run it for every customer.

1. Three days before due: a short, friendly note with the invoice attached. “Just a heads-up that invoice 1042 falls due on Friday.”
2. One business day after due: a phone call to accounts. Ask whether they’ve received it and when it’s scheduled for payment. Write down the date they give you.
3. Seven days overdue: an email confirming the promised date and restating the amount.
4. Fourteen days overdue: a call to your main contact, not just accounts. Ask directly whether there’s a problem with the work.
5. Twenty-one to thirty days overdue: a formal final notice, and a pause on new work or deliveries until the account is up to date.
6. Beyond that: a letter of demand, then the escalation options covered in our guide on your options when a customer pays late.

The phone call at step two does more work than any email. A person who has told you “it’s in Thursday’s run” is far more likely to make sure it is.

Sort your customers by how they really pay

Pull an aged receivables report and review each customer’s history over the past year or so. You’re looking for patterns, not individual invoices. Most businesses find their customers fall into three groups:

• Reliable: pay on time or close to it. Protect these relationships.
• Slow but steady: always pay, always late, but predictably. Price for the delay, plan for it, or finance it.
• Unpredictable: sometimes on time, sometimes 90 days, sometimes disputed. These carry the real risk.

For the unpredictable group, reduce your exposure. Set a credit limit, ask for deposits, shorten terms, or stop extending credit altogether. Our page on debtor days explains how to measure the overall drift, and the cash flow ratios guide shows how to track it monthly.

How do you keep the relationship while you chase?

Being firm and being friendly aren’t opposites. A few habits help:

• Assume good faith in the first contact. Most late invoices are forgotten, not withheld.
• Be specific. “Invoice 1042 for $8,400 was due on the 3rd” is easier to act on than “just checking on our account”.
• Ask about the work. If a customer is unhappy, you want to know now, not in month three.
• Offer a payment plan before they ask. Two instalments that actually arrive beat one payment that doesn’t.
• Don’t keep supplying a growing balance. Pausing new work is a reasonable, professional step, not a threat.

Where a large customer stays slow or a disagreement stalls, the federal small business ombudsman (ASBFEO) runs a dispute support tool and can point you to low-cost resolution options.

How do you cover the gap in the meantime?

A tidier collections process usually needs a few billing cycles before the bank balance reflects it. In the meantime the wages, BAS and supplier bills don’t move. A few options can bridge that gap.

Option	Works well when	The catch
Invoice finance	Customers are reliable but on long terms	Fees add up if you finance every invoice indefinitely
Business line of credit	The gap is recurring but varies month to month	Drawing it to cover a customer who never pays
Short-term unsecured loan	A one-off gap with a clear repayment date	Daily or weekly repayments starting before the cash arrives
Negotiating your own supplier terms	You can match outgoing timing to incoming	Burning goodwill with a supplier you need

If you’re weighing up invoice finance, the invoice finance calculator shows what an advance on a given invoice might cost in dollars. It’s also worth reading our guide to negotiating better supplier terms, since stretching outgoings a little can close the gap without borrowing.

A worked example: the electrical contractor and the 60-day builder

This example is invented to illustrate the approach. A Newcastle electrical contractor turns over about $1.4m a year. Two-thirds of the work comes from three builders. Over a year, average collection has drifted from around 30 days to 52, and the owner has twice had to delay their own super and BAS payments.

Step one: look at the data. The aged receivables report shows that one builder, worth about a third of revenue, consistently pays at 60 to 65 days. The other two pay at 30 to 35. A dozen smaller residential customers pay mostly on time, but three have balances past 90 days.

Step two: fix the friction. The contractor discovers that half the large builder’s invoices were missing a job number, which sent them to a queue for manual approval. Adding the number cuts that customer’s average to about 45 days within two months.

Step three: change terms for the risky group. New residential jobs now require a deposit, and the three 90-day customers are put on a payment plan with no new work until it’s current.

Step four: bridge the remainder. The large builder is reliable, just slow. The owner sets up invoice finance on that builder’s invoices only, which brings in most of the cash within a couple of days of each invoice instead of six weeks later.

Six months on, the business is collecting in around 36 days on average, and the finance facility is used for one customer, not all of them. The fees are a known, budgeted cost rather than a scramble.

Mistakes that make slow payment worse

• Invoicing in batches at month end. Each job finished early in the month waits an extra two or three weeks before its terms even start.
• Chasing only when you’re desperate. Customers learn that your terms are a suggestion.
• Offering an early payment discount to everyone. Reliable customers take it; slow ones ignore it. Target it.
• Keeping work going on an account that’s growing. The longer you supply, the more you have at risk.
• Financing a bad debt. Funding an invoice from a customer who may never pay just moves the loss.

Slow payers are squeezing you now: what next?

Fixing how you get paid is the long-term answer. Still, the stretch between finishing a job and banking the payment is real today, and it lands on the same week as payroll more often than seems fair. We talk to owners caught in exactly that gap all the time, and there’s usually more than one sensible way to cover it.

Our enquiry form takes about a minute. Sending it leaves your credit file untouched; nobody runs a check simply because you got in touch. We keep your enquiry in-house instead of firing it off to a string of funders, so no flood of calls follows. A member of our team looks over your circumstances personally, then phones you. Where you can, note who owes you, roughly how much, and how late they tend to pay. Getting those details right is what lets the first option we raise be the one that suits.
