Getting paid starts before the invoice is overdue

The sale felt finished when the work was delivered. Three weeks later, you discover the customer needed a purchase order number, the invoice went to the wrong person and their next payment run is another fortnight away.

Much of the work of getting paid happens before an invoice becomes overdue. Good collections begin with the agreement, continue through delivery and depend on the small administrative details being right.

This is worth management attention. Money waiting in customer accounts has already used your team’s time, your supplier credit or your bank balance. A full sales pipeline does not solve that delay automatically.

Remove the avoidable reasons for waiting

Before work begins, confirm the contracting entity, the authorised contact and the person or team that processes invoices. Check whether a purchase order, supplier onboarding or evidence of delivery is required.

Agree scope and payment terms in the contract or accepted quote. Where appropriate, consider a deposit, regular billing or progress payments that match the work. Do not rely on a new condition appearing for the first time at the bottom of the final invoice.

The business.gov.au guidance on payment terms explains their role in setting out how and when customers pay. Terms should be clear and suited to the transaction; particular industries and contracts can have additional rules.

When the billing milestone arrives, send the invoice promptly with the agreed description, supporting material and payment details. Give the customer a simple way to raise a query. An unresolved scope disagreement needs a conversation, not a sequence of increasingly blunt automated reminders.

Measure the delay in dollars

Consider a fictional business with annual credit sales of $730,000, excluding GST. That is $2,000 a day over 365 days. At an average collection period of 45 days, approximately $90,000 is tied up in receivables. At 30 days, the equivalent balance is $60,000.

The illustrative difference is $30,000. That is a potential release of working capital, not extra profit and not a guaranteed saving. Actual results depend on sales timing, customer behaviour, bad debts and how the calculation is prepared.

For a consistent days-sales-outstanding measure, use average receivables and credit sales from a matching period, with GST treated consistently. Do not compare a GST-inclusive debtor balance with GST-exclusive sales and assume the result is exact. A seasonal business should also inspect the underlying invoices rather than trusting one ratio.

Age the invoices, then look inside the buckets

An aged receivables report is a starting point. Separate amounts not yet due from overdue amounts, and confirm whether the software ages by invoice date or due date. The distinction can make a healthy account look late or hide a genuine delay.

Then identify the largest exposures and recurring causes. A $20,000 disputed invoice requires different attention from twenty small invoices awaiting a routine payment run. Keep notes on promised payment dates, the reason for delay and the next agreed action.

Assign responsibility. If everybody assumes somebody else is following up, the oldest balances quietly become part of the furniture. A short weekly review with one accountable person can be more effective than a long monthly discussion.

Make follow-up firm, calm and useful

A practical first reminder confirms the invoice, due date and payment options. If there is no response, make direct contact and establish whether the issue is administration, a dispute or an inability to pay. Those three problems need different responses.

Where a payment arrangement is commercially sensible, record the amounts and dates in writing and monitor whether they are met. Review further work or credit within the terms of the contract. Do not assume you can unilaterally add collection costs or late fees.

If the matter remains unresolved, consider appropriate dispute resolution or professional recovery advice. The Australian Government’s unpaid-invoice guidance sets out a progression from reminders to more formal options. Check disputed debts and legal requirements before escalating; pressure and threats can create a separate problem.

Collections are only part of the cash cycle

A business that holds stock also funds the time between paying for inventory and selling it. Unbilled work creates a similar delay in professional services. Map those steps alongside customer collection and supplier payment terms.

For example, faster invoicing will not release much cash if most completed jobs remain waiting for an internal sign-off. Better debtor follow-up will not fix a warehouse full of slow-moving stock. Find the point where money is waiting longest, then change the process around that point.

Track whether your changes work. Look at overdue dollars, disputes, time from delivery to invoicing and forecast receipts. Reward the team for clean billing and resolved queries as well as completed sales.

A reliable payment process protects relationships because expectations are clear from the beginning. It also means the owner can spend less time writing “just following up” and more time running the business those invoices belong to.
