You finished the work. You sent the invoice. Now the client has gone silent, or worse — they are making excuses, disputing the quality, or simply refusing to pay.
This guide gives you the exact escalation checklist to follow when a client refuses to pay your final invoice in Australia, including what each step costs, how long it takes, and when to move to the next stage.
Step 1: Send a Polite Reminder Email (Day 1-7)
Before you escalate, send a short, professional reminder. Many unpaid invoices are the result of disorganisation, not dishonesty.
What to include:
- Invoice number and date
- Amount owing
- Original payment terms
- Request for payment within 7 days
- Offer to discuss any concerns
Cost: $0 Timeframe: Send immediately after the due date passes
When to move on: If you receive no response or payment within 7 days, or if the client disputes the invoice without valid grounds.
Step 2: Letter of Demand (Day 8-14)
A Letter of Demand is a formal written notice that you intend to take legal action if payment is not made. It is the most effective tool for recovering unpaid invoices without going to court.
What it does:
- Formally demands payment within a specified timeframe (typically 7-14 days)
- Cites the relevant Australian law underpinning the debt
- States the consequences of non-payment (tribunal application, court action, interest, legal costs)
- Creates a paper trail for any future legal proceedings
Cost with ClaimDone: $79 (AI-generated, sent automatically) Timeframe: Prepared and delivered within 60 minutes
Legal basis:
When you provide goods or services and issue a valid tax invoice, you create a legally enforceable debt under Australian contract law. The Letter of Demand puts the debtor on notice that you are prepared to enforce that debt through formal channels.
What happens next:
Most clients pay after receiving a Letter of Demand. It signals that you are serious and prepared to escalate. If they still refuse or ignore it, you move to the next step.
Step 3: Final Demand (Day 15-21)
If the Letter of Demand does not produce payment, a Final Demand is your last pre-legal step. It is shorter, firmer, and explicitly states that legal proceedings will commence if payment is not received by a specific date.
What it includes:
- Reference to the previous Letter of Demand
- Final deadline for payment (typically 7 days)
- Clear statement that tribunal or court action will commence immediately after the deadline
- Updated total including any interest or costs incurred
Cost with ClaimDone: $79 (AI-generated, sent automatically) Timeframe: Prepared and delivered within 60 minutes
When to skip this step:
If the debt is large, the debtor is clearly avoiding you, or you have already given multiple warnings, you can skip straight to tribunal application after the Letter of Demand period expires.
Step 4: Tribunal Application (Day 22+)
If the client still refuses to pay, you file a claim with the relevant tribunal in your state. Tribunals are designed for small claims and operate with simplified procedures — no lawyer required.
Which tribunal:
- NSW: NSW Civil and Administrative Tribunal (NCAT)
- VIC: Victorian Civil and Administrative Tribunal (VCAT)
- QLD: Queensland Civil and Administrative Tribunal (QCAT)
- SA: South Australian Civil and Administrative Tribunal (SACAT)
- WA: State Administrative Tribunal (SAT)
- TAS: Tasmanian Civil and Administrative Tribunal (TasCAT)
- ACT: ACT Civil and Administrative Tribunal (ACAT)
- NT: Northern Territory Civil and Administrative Tribunal (NTCAT)
Claim limits:
Most tribunals handle claims up to $10,000-$25,000 (varies by state). Check your state tribunal’s monetary jurisdiction before filing.
What you need to file:
- Completed application form (available on the tribunal website)
- Copy of the invoice
- Copy of the contract or agreement (if applicable)
- Evidence of work completed (photos, emails, delivery receipts)
- Copies of your Letter of Demand and Final Demand
- Filing fee (typically $50-$300 depending on claim size and state)
Cost with ClaimDone: $197 (application prepared, ready to file) Timeframe: Application prepared within 60 minutes; tribunal hearing typically scheduled within 8-12 weeks
What happens at the hearing:
You present your evidence. The client presents their defence (if they show up). The tribunal member makes a binding decision. If you win, you get an order for payment. If the client still does not pay, you can enforce the order through debt collection or garnishment.
When to Involve a Lawyer
You do not need a lawyer for most unpaid invoice disputes. Tribunals are designed for self-representation. However, consider getting legal advice if:
- The debt is over $25,000
- The client is disputing the quality of your work with detailed technical arguments
- The contract is complex or unclear
- The client has filed a counterclaim against you
- The client is a company that may be insolvent
ClaimDone does not provide legal advice, but we prepare the documents you need to run the process yourself.
How to Prevent This Next Time
Once you recover the debt, update your processes to reduce the risk of non-payment:
Before you start work:
- Use a written contract or service agreement
- Require a deposit (30-50% upfront is standard)
- Include clear payment terms (due date, late fees, interest)
- Specify what happens if payment is not made
During the work:
- Send progress invoices for larger projects
- Communicate regularly about scope and expectations
- Document everything in writing (emails, photos, signed approvals)
After you finish:
- Send the invoice immediately
- Follow up at 7 days, 14 days, and 21 days if unpaid
- Do not wait months to take action

Final Checklist
When a client refuses to pay your final invoice, follow this sequence:
- Day 1-7: Send a polite reminder email
- Day 8-14: Send a Letter of Demand ($79 with ClaimDone)
- Day 15-21: Send a Final Demand if necessary ($79 with ClaimDone)
- Day 22+: File a tribunal application ($197 with ClaimDone)
Most clients pay after the Letter of Demand. The ones who do not typically pay after receiving the tribunal filing notice. Very few cases actually go to a hearing.
The key is to act quickly, document everything, and escalate in clear stages. Do not wait six months hoping the client will suddenly pay. The longer you wait, the harder it is to recover.
Start with a Letter of Demand prepared by ClaimDone — $79, delivered in 60 minutes, sent automatically to the debtor. Most unpaid invoices get resolved at this stage.
Frequently Asked Questions
How long should I wait before sending a Letter of Demand?
Send a polite reminder 7 days after the invoice due date. If you receive no response or payment within another 7 days, send the Letter of Demand. Do not wait months — the sooner you escalate, the more likely you are to recover the debt.
Can I charge interest on an overdue invoice in Australia?
Yes, if your contract or invoice terms include a clause allowing interest on overdue payments. Without a written agreement, you may be able to claim interest under relevant state legislation. The Letter of Demand should reference this where applicable.
What if the client disputes the quality of my work?
If the dispute is genuine and detailed, you may need to negotiate or provide evidence that the work met the agreed standard. If the dispute is clearly a stalling tactic with no substance, proceed with the Letter of Demand and tribunal application. The tribunal will assess the evidence from both sides.
Do I need a lawyer to file a tribunal application?
No. Tribunals are designed for self-representation. You present your evidence, the other party presents theirs, and the tribunal member makes a decision. ClaimDone prepares the application documents for you — you just need to file them and attend the hearing.
What happens if I win at tribunal but the client still does not pay?
You can enforce the tribunal order through a debt collector, garnishment of wages or bank accounts, or by registering a judgment against the debtor’s property. The tribunal order gives you legal authority to pursue these enforcement options.
