A final notice is a polite but firm written warning, sent by you, telling a customer that an invoice is overdue and that a formal letter of demand will follow if it is not paid by a set date. It sits between a friendly reminder and a letter of demand. Use it when the relationship is worth preserving or the debtor may simply have overlooked the invoice; go straight to a letter of demand when reminders have already been ignored.
A typical escalation for an unpaid invoice in Australia looks like this:
None of these steps is legally compulsory before the next. The sequence exists because each step is cheaper than the one after it, and because a debtor who receives a clear warning has fewer excuses later.

| Final notice | Letter of demand | |
|---|---|---|
| Who sends it | You | You, a solicitor, or an authorised agent such as PayClaim |
| Tone | Courteous, firm, still assumes an oversight | Formal, factual, assumes the debtor has chosen not to pay |
| What it warns of | That a formal letter of demand will follow | That court or tribunal action may follow |
| Purpose | Prompt payment while preserving the relationship | Prompt payment and create a documented pre-action record |
Sending a final notice to a debtor who has already ignored several reminders mostly just adds a week to the process.
Keep it under a page. Do not threaten court action in a final notice; save that for the letter of demand so the escalation is real.
Copy, replace the bracketed parts, and send by email and, if the amount warrants it, by post. Keep a copy and the sent record.

A final notice is a firm but courteous reminder that says a formal letter of demand will follow if the debt is not paid. A letter of demand is that formal, dated demand, with a clear deadline and a statement of what may happen next. The final notice is the softer step that comes first.
No. There is no legal requirement to send a final notice first. It is a courtesy step that can preserve a relationship and prompt payment without escalating. If you have already chased the debtor, you can go straight to a letter of demand.
Seven days is a common period, but you can choose any reasonable timeframe. The important thing is to state an explicit date rather than a vague phrase such as “as soon as possible”, so there is no argument later about when the time ran out.
Usually it is kept courteous and simply flags that a formal letter of demand will follow if the account stays unpaid. The firmer language about deadlines and consequences belongs in the letter of demand itself, not the final notice.
