Most advice about late payments assumes the problem is your customers. Often it is not. It is the gap between doing the work and sending the invoice, payment terms nobody ever agreed to in writing, and nothing being chased until it is well overdue.
Those are all yours to fix, and fixing them is faster than changing anyone else's payment behaviour.
What the numbers actually say
Australian small businesses were paid an average of 6.0 days late in the June 2026 quarter, down from 6.9 days in the March quarter, according to Xero Small Business Insights. The average total wait to be paid has been sitting around 24 days.
Two things follow from that, and they matter more than the headline.
First, six days late is an average. Your worst payers are considerably worse, and they are almost certainly a small number of accounts. Second, the wait is roughly 24 days while the lateness is only six — so most of the time between finishing work and having the money is not lateness at all. It is your terms, your invoicing speed, and your process.
Be careful with much larger figures you will see quoted on this topic. A lot of the widely-shared numbers come from businesses that sell invoice finance, and they have an interest in the problem sounding as expensive as possible. The pattern is real; treat the more dramatic dollar figures with suspicion unless you can see the method behind them.
Invoice the day the work is done
This is the single biggest lever and it costs nothing.
If you invoice weekly, your average invoice sits on your desk for three and a half days before the clock even starts. If you invoice monthly, it is about fifteen. A 30-day term invoiced fifteen days late is really a 45-day term, and you agreed to it yourself.
What to do this week:
- Invoice on completion, not on a billing run. For most small businesses this is the difference between being paid in the current month and the next one.
- If work is ongoing, invoice on a fixed day each week rather than each month.
- For anything large, invoice in stages — a deposit, a milestone, a balance — rather than everything at the end.
Make the terms explicit before you start
A surprising number of small businesses have never actually stated their payment terms anywhere the customer had to read them. "30 days" appearing on an invoice for the first time is not an agreement; it is a hope.
Put the terms in the quote, above the signature, in the same size type as everything else. State the number of days, what starts the clock, and what happens if it passes. Then put the same terms on the invoice so the two match.
This matters most with larger customers. Big organisations pay to their own schedule, and that schedule is often set by what the supplier agreed to at onboarding. If you never negotiated, you were assigned whatever their standard is.
Remove every reason to delay
Most late payments are not decisions. They are friction.
- Make the invoice payable in one click. If someone has to open online banking and rekey a BSB, they will do it later. Later is the problem.
- Address it to the person who pays, not the person who hired you. In anything larger than a few staff these are different people, and an invoice sitting in the wrong inbox is invisible.
- Include their reference. Many businesses cannot process an invoice without a purchase-order number. Ask for it before you start, not after they reject the invoice.
- Check the invoice is right. A disputed line is the cheapest possible excuse to pay nothing at all for another fortnight.
Chase early, politely, and on a schedule
The most effective change most businesses make is starting earlier and stopping the guesswork about when to follow up.
A workable sequence:
- Three days before due — a short, friendly note confirming the invoice is coming up, and asking whether everything is in order. This is not chasing. It surfaces problems while there is still time to fix them.
- Day one overdue — a brief factual reminder with the invoice attached again.
- Day seven — a phone call. Not an email. Calls are dramatically more effective and they identify the accounts that are stalling deliberately.
- Day fourteen — a firmer written note that says what happens next and when.
The reason to write the sequence down is that it stops the decision being emotional. Chasing feels awkward when it is a judgement call each time. It stops feeling awkward when it is simply the process, applied to everybody.
Know which customers are actually the problem
Sort your last twelve months of invoices by how many days late each one was paid, then group by customer. Most businesses find that a small number of accounts produce nearly all the pain, and that they have never quantified it.
That list changes the conversation. "You are on 30 day terms and your last six invoices averaged 52 days" is a discussion. "You always pay late" is an argument.
It also tells you which relationships are worth repricing. A customer who pays three weeks late is quietly borrowing from you, and that cost belongs in what you charge them.
Where this stops being a process problem
Some of it will not be fixable by better admin. If a customer is not paying because they cannot, no reminder schedule helps, and the priority becomes limiting exposure rather than collecting faster. If an amount is large enough to threaten your own ability to pay staff or suppliers, that is the point to get specific advice about your options rather than sending another email.
The sequence above is about the ordinary case, which is most cases: money that will arrive, arriving too slowly, largely because nothing in the process was designed to make it arrive sooner.
What to do next
Pick the two that apply to you and do them this week:
- Move invoicing to the day work finishes.
- Put payment terms in your quote template.
- Add a one-click payment option to your invoices.
- Write down the four-step chase sequence and apply it to everyone.
- Sort last year's invoices by days late and find your worst three accounts.
None of these require a difficult conversation, and together they typically move more days than any amount of chasing does.
