Unpaid Contractor Invoice NSW: Your Debt Recovery Options Step-by-Step

You finished the job. You sent the invoice. The client has gone quiet. If you are a contractor in New South Wales with an unpaid invoice, you have clear legal options. Knowing the exact sequence saves you time, money, and stress.

This guide walks you through the NSW debt recovery pathway, from the first polite nudge to filing in the NSW Civil and Administrative Tribunal (NCAT). You will see what each step costs, how long it takes, and when to escalate.

Start with an invoice reminder (no cost, 7 days)

Before you threaten legal action, send a plain invoice reminder. Many unpaid invoices result from disorganisation, not dishonesty. A simple email or text message works:

• Attach the original invoice
• Reference the job completed and the agreed price
• State the payment due date
• Ask for payment within 7 days

This step costs nothing and resolves a surprising number of disputes. If the client responds with a genuine query, you may need to clarify the work scope or provide additional documentation. If they ignore you completely, escalate.

Send a letter of demand (from $79, 7–14 days)

A letter of demand is a formal written notice that states the amount owed, cites the relevant law, gives a final deadline to pay, and warns that legal proceedings will follow if payment is not made.

In NSW, a properly drafted letter of demand often prompts immediate payment because the debtor realises you are serious and legally informed.

What the letter should include:

• Your details and the debtor’s details
• Invoice number, date, and amount
• Description of the work performed
• Payment terms agreed (verbal or written contract)
• Clear deadline and consequences for non-payment

Cost and timeframe:

• DIY letter: Free, but risks being ignored if poorly worded
• Lawyer-drafted letter: $300–$800, can take several days
• ClaimDone AI-generated letter: $79 flat fee, drafted and sent within 60 minutes

A letter of demand is not just a threat. It is typically expected by NCAT if you later file a claim, demonstrating you made a reasonable attempt to resolve the matter first.

Consider a final demand (optional, from $79, 7 days)

If the debtor ignores your first letter of demand, you can send a final demand before filing. This is a shorter, sharper notice that repeats the amount owed, states that the previous demand was ignored, gives a final 7-day deadline, and explicitly warns that NCAT proceedings will be commenced.

A final demand is not legally required, but it demonstrates good faith and gives the debtor one last chance to pay before you incur tribunal filing fees.

File a claim in NCAT (from $53, 6–12 weeks)

If the debtor still refuses to pay, your next step is the NSW Civil and Administrative Tribunal. NCAT handles debt claims up to $30,000 in the Consumer and Commercial Division.

NCAT filing fees (as of 2025):

• Claims up to $5,000: $53
• Claims $5,001–$10,000: $158
• Claims $10,001–$30,000: $316

You file online through the NCAT website. You will need:

• Completed application form
• Copy of your invoice
• Copy of your letter of demand
• Any contract, quote, or written agreement
• Evidence of work completed (photos, emails, timesheets)
• Proof of delivery or service (if applicable)

Timeframe:

• NCAT typically schedules a hearing 6–12 weeks after filing
• You may be directed to a conciliation conference first
• If the matter settles at conciliation, you avoid a hearing

At the hearing:

• Both parties present their case
• The tribunal member asks questions
• You present your evidence (bring physical copies)
• The tribunal makes a binding decision

If you win, NCAT issues an order requiring the debtor to pay. If the debtor still does not pay, you can enforce the order through a garnishee, writ of execution, or examination summons.

Enforce the NCAT order (from $100, 2–8 weeks)

An NCAT order is legally binding, but it does not automatically put money in your account. If the debtor ignores the order, you must take enforcement action.

Enforcement options in NSW:

• Garnishee order: Intercepts money owed to the debtor by a third party (e.g., their bank account or wages). Filing fee: $100.
• Writ of execution: Authorises a sheriff to seize and sell the debtor’s property. Filing fee: $200, plus sheriff’s fees.
• Examination summons: Requires the debtor to attend court and disclose their financial situation. Filing fee: $100.

Enforcement can be slow and uncertain. If the debtor has no assets or income, you may never recover the debt. This is why many contractors prefer to settle before filing, even for less than the full amount.

When to consider a statutory demand (debts over $4,000 against companies)

If your debtor is a registered company (Pty Ltd or Ltd) and the debt is at least $4,000, you can serve a statutory demand. This is a federal process available to NSW contractors.

A statutory demand gives the company 21 days to pay or face wind-up proceedings. It is the most aggressive debt recovery tool available and often results in immediate payment.

Requirements:

• Debt must be at least $4,000
• Debtor must be a registered company (not a sole trader or partnership)
• Debt must be liquidated and undisputed
• You must use the prescribed Form 509H
• You must swear a supporting affidavit

If you meet these criteria, a statutory demand is faster and more effective than NCAT. Most companies pay within days rather than risk insolvency proceedings.

Most contractors recover their money at the letter of demand stage. If you reach NCAT, you will almost certainly win, but enforcement is not guaranteed.

Frequently Asked Questions

Do I need a written contract to recover an unpaid invoice in NSW?

No. A verbal agreement is legally binding in NSW. You will need evidence of the agreed price and scope of work — text messages, emails, quotes, or witness statements all count. A written contract makes proof easier, but it is not required.

How long do I have to chase an unpaid contractor invoice in NSW?

You typically have 6 years from the date the debt became due under NSW limitation law. After 6 years, the debt is statute-barred and cannot be recovered through court or tribunal proceedings.

Can I add interest to an unpaid invoice in NSW?

Yes, if your contract or invoice terms included an interest clause. If not, you can typically claim interest under NSW civil procedure law from the date the debt became due until judgment. NCAT can also award interest as part of your claim.

What happens if the debtor does not show up to the NCAT hearing?

NCAT can make a decision in the debtor’s absence if you attend and present your evidence. This is called a default judgment. The debtor can apply to set it aside if they have a reasonable excuse, but most default judgments stand.

Can I recover my legal costs and NCAT filing fees?

NCAT can order the debtor to pay your filing fee and reasonable costs, but this is not automatic. You must ask for it in your application. Legal costs are rarely awarded in small claims, but filing fees and service costs usually are.
