You did the work. You sent the invoice. The payment date passed. Now silence.
When a client won’t pay your invoice in Australia, you have clear legal options. The key is knowing when to escalate and how to do it properly. This guide maps the entire recovery process from first reminder to tribunal filing.
Step 1: Send a Friendly Reminder (Day 7-14 After Due Date)
Start with the assumption of good faith. Invoices get missed, emails land in spam, finance teams make mistakes.
Send a polite email:
- Reference the invoice number and amount
- Attach the original invoice again
- Ask if there are any issues preventing payment
- Set a new payment deadline (typically 7 days)
Keep the tone professional. Most payment delays resolve at this stage.
When to skip this step: If the client has already ignored multiple invoices, is clearly avoiding you, or the debt is substantial and time-sensitive.
Step 2: Make Direct Contact (Day 14-21)
If the reminder gets no response, pick up the phone.
Ask:
- Have they received your invoice?
- Is there a dispute about the work quality or amount?
- When can you expect payment?
Document everything:
- Date and time of the call
- Who you spoke to
- What they said
- Any commitments made
If they acknowledge the debt and request more time, get it in writing. A simple email confirming “payment by [date]” creates evidence you can use later.
Red flags at this stage:
- Vague excuses with no concrete timeline
- Claims they “never received” multiple invoices
- Suddenly questioning work quality that was previously accepted
- Refusing to engage at all
Step 3: Send a Final Invoice Notice (Day 21-30)
This is your last informal attempt before formal action.
Send a written notice (email is fine) stating:
- The outstanding amount and invoice details
- All previous attempts to resolve the matter
- A final deadline for payment (typically 7 days)
- A clear statement that you will commence formal recovery action if payment is not received
Sample language: “This is a final notice regarding invoice #[number] for $[amount], now [X] days overdue. If payment is not received by [date], I will commence formal debt recovery proceedings without further notice.”
Step 4: Letter of Demand (Day 30+)
When informal methods fail, a Letter of Demand is your first formal step.
What it is: A formal legal document demanding payment within a specified timeframe (typically 7-14 days) and warning of legal action if ignored.
Why it works: Most clients pay at this stage because:
- It signals you are serious
- It creates a formal record for any future court proceedings
- It demonstrates they have been given fair opportunity to pay
- Many businesses have policies to settle demands immediately to avoid legal costs
What to include:
- Detailed breakdown of the debt (invoice numbers, dates, amounts)
- The legal basis for your claim (breach of contract, services rendered, goods supplied)
- Copies of all supporting evidence (invoices, contracts, correspondence)
- A clear deadline for payment
- Statement of your intention to commence tribunal or court proceedings if unpaid
ClaimDone prepares your Letter of Demand by reading your uploaded evidence and drafting a professionally formatted document that gets delivered automatically to the client. Flat fee $79, done in 60 minutes.
Step 5: Tribunal Application (If Demand Ignored)
If your Letter of Demand is ignored and the debt is under the tribunal threshold in your state, your next step is a tribunal application.
State thresholds (for small claims divisions):
- NSW (NCAT): up to $30,000
- VIC (VCAT): up to $10,000
- QLD (QCAT): up to $25,000
- WA (SAT): up to $10,000
- SA (SACAT): up to $12,000
Why tribunals work for unpaid invoices:
- Low filing fees (typically $50-$200)
- No lawyers required
- Fast hearings (typically 6-12 weeks)
- Enforceable orders
What you need to file:
- Completed application form for your state tribunal
- Statement of claim explaining the debt
- All supporting evidence (invoices, contracts, proof of delivery, correspondence)
- Proof you attempted to resolve the matter (your Letter of Demand)
- Filing fee
The process:
- File your application with the tribunal
- The tribunal serves the respondent (your client)
- They have 28 days to file a defence
- If they defend, a hearing is scheduled
- If they don’t respond, you can apply for default judgment
- At hearing, both sides present evidence
- Tribunal member makes a binding decision
If you need to escalate to tribunal, ClaimDone prepares your complete application pack — the statement of claim, evidence summary, and all required forms — ready to file with your state tribunal.
Step 6: Enforcing Your Judgment
Winning at tribunal gets you an order. Collecting the money is a separate step.
Enforcement options:
- Garnishee order: Takes money directly from their bank account
- Instalment order: Court-ordered payment plan
- Warrant for seizure: Sheriff seizes and sells their assets
- Examination summons: Forces them to disclose their financial position under oath
Each state has different enforcement procedures. Most tribunals provide guidance on how to enforce your order.
When to Involve a Lawyer
You can handle most unpaid invoice matters yourself through tribunal. Consider a lawyer if:
- The debt exceeds your state tribunal threshold
- The client has raised complex legal defences
- The matter involves cross-claims or counterclaims
- You are dealing with a company that has gone into liquidation
- The client is overseas
Prevention: How to Reduce Future Non-Payment
Once you have recovered this debt, protect yourself going forward:
Before work starts:
- Get written contracts for all jobs
- Include clear payment terms (due date, late fees, interest)
- Request deposits for large projects
- Run credit checks on new commercial clients
During the job:
- Send progress invoices for long projects
- Get written approval for variations
- Document everything in writing
After completion:
- Invoice immediately upon completion
- Include all required details (ABN, payment methods, due date)
- Follow up promptly on overdue accounts

Frequently Asked Questions
How long should I wait before sending a Letter of Demand for an unpaid invoice?
Most businesses wait 30 days after the invoice due date, after sending at least one reminder. If the client is clearly avoiding payment or the amount is substantial, you can send a Letter of Demand sooner. There is no mandatory waiting period under Australian law.
Can I charge interest on an overdue invoice in Australia?
Yes, but only if your original invoice or contract included terms allowing interest on late payments. Without a written agreement, you cannot unilaterally add interest. If you have a written term, some states set maximum rates for penalty interest.
What if my client claims the work was defective after I send a Letter of Demand?
If they raise a genuine dispute about quality, you may need to address it before recovering payment. However, if they previously accepted the work without complaint and only raised issues after you demanded payment, this is often a delaying tactic. Document all prior communications showing acceptance of the work.
Do I need a lawyer to take a client to tribunal for an unpaid invoice?
No. Australian tribunals are designed for self-representation. You file the application yourself, present your evidence at the hearing, and the tribunal member makes a decision. Lawyers are allowed but not required. For straightforward unpaid invoice matters, most people represent themselves successfully.
What happens if I win at tribunal but the client still won't pay?
A tribunal order is legally enforceable. You can apply for enforcement through garnishee orders (taking money from their bank account), instalment orders, warrants for seizure of assets, or examination summons to force disclosure of their finances. Each state tribunal has an enforcement process.
