Sole Trader Chasing Unpaid Invoices in NSW: Your Complete Roadmap

You finished the job. You sent the invoice. The client went quiet. Now you are out of pocket and wondering what happens next.

If you are a sole trader in NSW chasing unpaid invoices, the process is straightforward: send a formal demand, escalate to the NSW Civil and Administrative Tribunal (NCAT) if ignored, then enforce the judgment if you win. This guide walks you through each stage, the costs involved, and how long it takes.

Why unpaid invoices hit sole traders harder

Sole traders operate without the cashflow buffer of a larger business. One unpaid invoice can mean you cannot pay suppliers, cover rent, or take the next job.

NSW has a clear, accessible system for recovering debts under $20,000 through NCAT’s Small Claims Division. You do not need a lawyer. You just need to follow the steps in order.

Step 1: Send a letter of demand

Before you can file at NCAT, you must give the debtor a reasonable opportunity to pay. A letter of demand does exactly that.

What it must include:

• Amount owed (itemised if multiple invoices)
• Date the debt became due
• Reference to the original invoice(s) or contract
• Clear deadline to pay (typically 7-14 days)
• Statement of what happens if they do not pay (NCAT application)
• Your contact details for payment or dispute

How to send it:

• Email with read receipt, or
• Registered post, or
• Both

Keep proof of delivery. NCAT will ask for it.

Most demand letters give 7-14 days to pay. If the debtor responds disputing the debt, you may need to negotiate or provide further evidence before proceeding. If they ignore it completely, you can file at NCAT once the deadline passes.

Step 2: File at NCAT (if the demand is ignored)

NCAT is NSW’s tribunal for civil disputes under $20,000. It is faster, cheaper, and less formal than court.

Eligibility:

• Debt is $20,000 or less
• Debt relates to goods sold, services provided, or a contract
• Debtor is in NSW or the contract was performed in NSW
• You have evidence (invoice, contract, correspondence, proof of work completed)

Filing fee:

• $51 for claims up to $2,500
• $102 for claims $2,501 to $5,000
• $204 for claims $5,001 to $10,000
• $408 for claims $10,001 to $20,000

What you need:

• Completed NCAT application form (available online)
• Copy of your letter of demand and proof of delivery
• Copies of invoices, contracts, emails, or other evidence
• Debtor’s full name and address

NCAT typically schedules a hearing within 4-8 weeks of filing. You will receive a notice with the date, time, and whether it is in-person or by phone.

Step 3: Prepare for the hearing

NCAT hearings are informal, but you still need to be organised.

What to bring:

• All invoices and contracts
• Proof the work was completed (photos, delivery receipts, emails)
• Your letter of demand and proof it was sent
• Any correspondence with the debtor
• A chronology (timeline of events) if the case is complex

What happens at the hearing:

The tribunal member will ask you to explain your claim. The debtor (if they attend) will have a chance to respond. The member will then make a decision, either on the day or within a few weeks.

If the debtor does not show up:

You can ask for a default order in your favour. Bring all your evidence anyway — the tribunal still needs to be satisfied the debt is owed.

Step 4: Enforce the judgment

Winning at NCAT gives you an enforceable order. If the debtor still does not pay, you have several enforcement options.

Payment plan:

NCAT can order the debtor to pay in instalments. This is common when the debtor has limited income.

Garnishee order:

You can apply to garnish the debtor’s wages or bank account. This requires knowing where they work or bank.

Writ of execution:

A sheriff can seize and sell the debtor’s property to recover the debt. There is a fee for this service.

Examination notice:

You can require the debtor to attend court and disclose their financial situation under oath. This helps you identify assets or income streams.

Bankruptcy notice (if debt is $10,000+):

If the debt is over $10,000, you can issue a bankruptcy notice. If the debtor does not pay within 21 days, you can apply to make them bankrupt. This is serious and expensive, but effective against debtors who are hiding assets.

Enforcement costs vary. Garnishee applications cost around $100. Writs of execution involve sheriff’s fees. Budget for $200-$500 in enforcement costs depending on the method.

What if the debtor disputes the invoice?

If the debtor genuinely disputes the debt — claiming the work was defective, incomplete, or not authorised — NCAT will hear both sides.

Your job:

Prove the work was completed to the agreed standard. Bring photos, signed quotes, emails approving the scope, delivery receipts, or witness statements if needed.

Common defences:

• “The work was not finished” — show evidence it was, or explain why (e.g. client stopped responding)
• “The quality was poor” — show the work met the agreed specification
• “I never agreed to this price” — produce the signed quote or email confirmation

If the debtor raises a genuine dispute, the tribunal will assess the evidence and decide. If their defence is weak or unsupported, you will still win.

What if the debtor has no money?

Winning at NCAT does not guarantee payment. If the debtor is genuinely broke, enforcement may be futile.

Practical options:

• Negotiate a payment plan (even $50/week is better than nothing)
• Wait and enforce later if their situation improves
• Write it off and move on (sometimes the cost of enforcement exceeds the debt)

If the debtor is a company, you can issue a statutory demand (if the debt is $4,000+). If they do not pay within 21 days, you can apply to wind them up.

Key takeaways for NSW sole traders

Act fast: The longer you wait, the harder it is to recover. Send a demand letter within 30 days of the invoice becoming overdue.

Keep records: Every email, every text, every photo. NCAT decisions are based on evidence.

Use NCAT: It is designed for small business. The fees are low, the process is accessible, and you do not need a lawyer.

Enforce if you win: A tribunal order is worthless unless you enforce it. Budget for enforcement costs upfront.

Know when to walk away: If the debtor has no assets and no income, enforcement may cost more than the debt.

Frequently Asked Questions

How long does a sole trader have to chase an unpaid invoice in NSW?

You typically have six years from the date the debt became due under NSW limitation law. After six years, the debt becomes statute-barred and you cannot enforce it through NCAT or the courts. Act within the first year for the best chance of recovery.

Can I recover my NCAT filing fee if I win?

Yes. NCAT can order the debtor to pay your filing fee as part of the judgment. You can also claim reasonable costs directly related to the dispute, such as registered post fees for your demand letter. You cannot claim for your time or lost income.

What if the debtor is interstate or overseas?

If the debtor is outside NSW, you can still file at NCAT if the contract was performed in NSW or the goods were delivered in NSW. Enforcing an NCAT order interstate requires registering the judgment in the debtor’s state, which adds time and cost. Overseas debtors are much harder to pursue.

Do I need a lawyer to recover an unpaid invoice at NCAT?

No. NCAT is designed for self-represented parties. The process is straightforward: file the application, attend the hearing, present your evidence. Lawyers are allowed but not required. Most sole traders represent themselves successfully in small claims matters.

What happens if the debtor files for bankruptcy after I get an NCAT order?

If the debtor becomes bankrupt, you become an unsecured creditor in the bankruptcy. You will need to lodge a proof of debt with the bankruptcy trustee. Unsecured creditors rarely recover the full amount. This is why acting fast and enforcing quickly matters.
