How to Follow Up an Overdue Invoice in Australia

Use this workflow when the invoice is already overdue and you need the next document, not just a harder email.

1. Start with a reminder that restates the debt

The first follow-up document should restate the invoice reference, due date, overdue amount, and payment instructions in a cleaner format than an ad hoc email. That keeps the debt trail clear and makes the next step easier.

2. Use a statement when the client needs the full balance view

If there are multiple invoices or partial payments, a statement of account is usually more useful than another short reminder. It shows invoice-by-invoice totals and helps the customer reconcile the account.

3. Move to a payment plan when full settlement is not realistic

When the client cannot pay the whole balance immediately, a payment plan agreement documents the staged repayments and gives both sides a clearer record of what was agreed.

4. Close the workflow with a receipt

Once the balance is paid, issue a receipt instead of leaving the workflow open. If the original invoice amount needs to be reduced, issue a credit note rather than trying to fix the debt trail inside the reminder itself.

How much time to give between each step

There is no single legally mandated timeline for chasing overdue invoices in Australia, so the cadence is a business decision. A common pattern is a short grace period after the due date, a reminder within the first week of the invoice becoming overdue, a follow-up statement or second reminder around the two-to-three week mark if there has been no response, and a conversation about a payment plan once the debt has run a month or more without any contact from the client. Slow down the cadence for a client who is responsive but genuinely delayed, and speed it up for a client who has gone silent.

Keep every document, even the awkward ones

Every reminder, statement, payment plan, and eventual receipt or credit note forms a record of what was agreed and when. If a debt ever needs to be escalated to a collection agency or small claims process, having a clean, dated trail of documents makes the case far easier to support than a scattered history of emails and phone calls.

It also protects the relationship on the client's side — a professional, consistently worded sequence of documents reads as a normal business process, whereas an inconsistent mix of terse emails and informal texts can come across as more confrontational than intended, even when the underlying message is the same.

Frequently asked questions

How soon after the due date should the first reminder go out?

A short grace period of a few days is common before sending the first reminder, since payments can genuinely be in transit. Once it is clearly overdue — commonly within a week of the due date — send a reminder that restates the invoice details rather than letting the account sit unaddressed.

What if the client disputes the invoice instead of paying it?

Pause the collection sequence and resolve the dispute first. If the dispute is valid, issue a credit note to correct the amount rather than continuing to chase the original figure. If it is not valid, document the response in writing before resuming reminders, since a documented dispute record matters if the debt ever needs to be escalated further.

When should a business consider debt collection or legal action?

That is usually a last resort after reminders, a statement, and a payment plan have all failed to produce a result, and the amount owed is significant enough to justify the cost and time of formal recovery. Many small businesses set an internal threshold — both a dollar amount and a number of days overdue — before escalating beyond their own documents.
