You delivered the work. The invoice went out. The payment date passed. You followed up politely. Then again. Now the client has gone quiet, made excuses, or flat-out refused to pay.
Australian law gives you clear remedies. The key is knowing which step to take, when to take it, and how to document everything properly.
Why clients refuse to pay (and why it doesn’t matter)
Clients refuse to pay for all sorts of reasons:
- Cash flow problems in their own business
- Dispute over scope, quality, or completion
- Buyer’s remorse or change of priorities
- Genuine financial hardship
- Bad faith—they never intended to pay
If you delivered what was agreed, you are entitled to payment. Australian contract law does not require you to absorb someone else’s financial mismanagement.
Understanding why they’re refusing helps you choose the right approach. A client disputing quality needs a different response than a client who simply has no money.
Step 1: Confirm the basics before escalating
Before you send anything formal, make sure your position is solid.
Check your contract or agreement. Did you have written terms? What did you agree to deliver? What were the payment terms? If you’re working off a quote, email exchange, or verbal agreement, gather every piece of evidence that shows what was agreed.
Confirm delivery or completion. Do you have proof the work was done? Emails, photos, signed delivery dockets, timesheets, completion certificates—anything that shows you held up your end.
Check your invoice. Is it clear, accurate, and correctly addressed? Does it reference the agreement? Does it specify a due date? A poorly drafted invoice weakens your position.
Review any disputes. Has the client raised specific complaints about the work? If so, are they legitimate? If the complaint is baseless or exaggerated, document your response. If there is a genuine defect, you may need to remedy it before demanding full payment.
If everything checks out and the client still refuses to pay, it’s time to escalate.
Step 2: Send a letter of demand
A letter of demand is the first formal step in debt recovery. It is a written notice that:
- States the amount owed
- Explains the basis of the debt (the agreement, the work done, the invoice)
- Cites the applicable law
- Gives the debtor a deadline to pay (typically 7–14 days)
- Warns of legal action if payment is not received
Most people pay after receiving a demand letter. It signals you are serious, creates a paper trail, and shows you understand your legal rights. Many clients who were “too busy” or “waiting on funds” suddenly find the money when a formal demand arrives.
The letter must be professional, factual, and legally grounded. It should not be emotional, threatening, or vague.
ClaimDone generates a letter of demand based on the evidence you upload, cites the relevant Australian law, and delivers it automatically via registered post and email. Flat fee, no subscription, done in 60 minutes.
Step 3: Follow up with a final demand (if needed)
If the first letter gets no response, send a final demand. This is a shorter, sharper notice that makes it clear you are proceeding to the next step unless payment is received immediately.
The final demand should:
- Reference the original demand letter and the lack of response
- Restate the amount owed
- Give a final deadline (typically 7 days)
- Specify the next step (tribunal application, statutory demand, or court action)
This is your last attempt to resolve the matter without legal proceedings.
Step 4: Lodge a tribunal application
If the debt is under the tribunal limit in your state (typically $10,000–$25,000 depending on jurisdiction), the small claims tribunal is your next step. Tribunals are designed for disputes like this—low cost, no lawyers required, fast resolution.
What you need:
- Completed application form (varies by state)
- Copy of your contract, quote, or agreement
- Copy of your invoice
- Proof of delivery or completion
- Copies of your demand letters
- Any correspondence with the client
What happens: The tribunal will schedule a hearing. Both parties attend. You present your evidence. The client presents their defence (if they have one). The tribunal member makes a binding decision. If you win, you get an order for payment.
Enforcement: If the client still doesn’t pay after a tribunal order, you can enforce it through wage garnishment, bank account seizure, or property liens.
ClaimDone prepares tribunal applications for all Australian states and territories. You upload your evidence, answer a few questions, and the Proprietary AI Engine generates a complete application pack ready to file.
Step 5: Consider a statutory demand (for company debtors)
If your client is a registered company (Pty Ltd or Ltd) and owes you $4,000 or more, you can serve a statutory demand under the Corporations Act.
A statutory demand gives the company 21 days to pay the debt or apply to set aside the demand. If they do neither, you can apply to wind up the company. This is the most aggressive debt recovery tool available in Australia, and it works—most companies pay rather than face insolvency proceedings.
Requirements:
- Debt must be at least $4,000
- Debtor must be a registered company (check ASIC register)
- Debt must be liquidated (a specific amount, not estimated damages)
- Debt must not be genuinely disputed
ClaimDone prepares statutory demand documents with supporting affidavits for $197. The document is ready to serve within 60 minutes.
When to get a lawyer involved
Most unpaid invoice disputes can be resolved without a lawyer. Demand letters, tribunal applications, and statutory demands are all designed for self-representation.
However, you should consider legal advice if:
- The debt is large (over $25,000)
- The client has raised complex legal defences
- You are being counter-sued
- The matter involves fraud, insolvency, or criminal conduct
- You need to enforce a judgment against hidden assets
ClaimDone does not provide legal advice. For complex or high-value matters, consult a qualified Australian lawyer.
How to avoid this situation next time
Prevention is better than debt recovery. Here’s how to reduce the risk of non-payment:
Use written contracts. Even a simple email confirming scope, price, and payment terms is better than nothing. For larger jobs, use a formal service agreement.
Invoice promptly. Send the invoice as soon as the work is complete. The longer you wait, the harder it is to collect.
Set clear payment terms. Specify due dates, late fees, and consequences for non-payment in your contract.
Take deposits. For large projects, take 30–50% upfront. This reduces your exposure and filters out bad-faith clients.
Check creditworthiness. For new clients or large jobs, do a basic credit check or ask for references.
Follow up early. If a payment is one day late, send a polite reminder. If it’s a week late, call them. The earlier you act, the more likely you are to get paid.

Ready to recover your unpaid invoice?
Start with a demand letter. If that doesn’t work, escalate to a final demand. If they still refuse, lodge a tribunal application or serve a statutory demand. Most clients pay before it gets to court.
The key is to act quickly, document everything, and follow the process step by step. The longer you wait, the harder it becomes to recover the debt.
ClaimDone can have your demand letter drafted and sent within the hour—upload your invoice and evidence to get started.
Frequently Asked Questions
Can I charge interest on an overdue invoice in Australia?
Yes, if your contract or invoice terms include a late payment clause specifying the interest rate. Without a written agreement, you cannot automatically charge interest. However, once you obtain a court or tribunal judgment, interest typically accrues at the statutory rate set by the relevant court.
What if the client disputes the quality of my work?
If the dispute is genuine and relates to a material defect, you may need to remedy the issue before demanding full payment. If the complaint is baseless or exaggerated, document your position in writing and proceed with a demand letter. Tribunals assess whether the work met the agreed standard based on the evidence presented.
How long do I have to recover an unpaid invoice?
In most Australian states, you have six years from the date the debt became due to take legal action. This is the limitation period for contract debts. After six years, the debt may be statute-barred and unenforceable.
What happens if the client ignores my demand letter?
If the client does not respond or pay within the deadline, you escalate to the next step—either a final demand, a tribunal application, or (for company debtors) a statutory demand. Ignoring a demand letter does not make the debt go away; it strengthens your case for formal proceedings.
Can I take a client to court for an unpaid invoice under $1,000?
Yes, but it may not be cost-effective. Small claims tribunals have low filing fees and are designed for disputes of any value. For very small debts, consider whether the time and cost of pursuing the matter is worth the amount owed.
