Client Won’t Pay Your Invoice: Your Step-by-Step Recovery Process

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.

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.

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

Claim Done prepares your Letter of Demand from what you tell us about your evidence, drafting a professionally formatted document that gets delivered by email to the client. Flat fee, done in about 5 minutes.

Step 5: Tribunal Application (If Demand Ignored)

If your Letter of Demand is ignored, your next step is a claim in the right tribunal or court for your state.

Where unpaid invoices go:

• New South Wales: the Local Court of New South Wales (Small Claims Division up to $20,000; General Division over $20,000 up to $100,000)
• Victoria: VCAT, Civil Claims List
• Queensland: QCAT, minor civil dispute, up to $25,000 (above that, the Magistrates Court)
• Western Australia: the Magistrates Court of Western Australia (minor case claims up to $10,000; general procedure claims up to $75,000)
• South Australia: the Magistrates Court of South Australia (minor civil action up to $12,000; general claims up to $100,000)

Why small claims work for unpaid invoices:

• Lower filing fees than the higher courts
• No lawyers required
• Less formal hearings
• Enforceable orders

Fees change each 1 July; check the current fee on the tribunal’s or court’s website before you file.

What you need to file:

• Completed application form or statement of claim for your state’s tribunal or court
• 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:

1. File your application or claim with the tribunal or court
2. The respondent (your client) is served, by the tribunal or by you, depending on the forum
3. They have a set time to file a defence
4. If they defend, a hearing is scheduled
5. If they don’t respond, you can apply for default judgment
6. At hearing, both sides present evidence
7. The tribunal member or magistrate makes a binding decision

If you need to escalate, Claim Done’s Tribunal Application ($97) drafts the claim you file in your state’s tribunal or court — the application document or statement of claim — plus a witness statement.

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.

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

Claim Done’s Service Agreement template sets clear terms from the start — it includes payment terms, dispute resolution clauses, and all the protections you need.

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?

Contract interest needs a term in your contract or invoice. Without one, you can still ask the court for interest up to judgment, for example under s 100 of the Civil Procedure Act 2005 (NSW) for claims of $1,000 or more. 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 and the small claims divisions of the courts 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, many people represent themselves.

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.
