Client Won’t Pay Your Invoice? Here’s Your 3-Step Debt Recovery Process

You did the work. You sent the invoice. The payment date passed. Now your client won’t pay, won’t respond, or keeps making excuses.

This happens to every service provider eventually — tradies, consultants, designers, contractors, accountants. This guide provides the exact 3-step escalation process used by Australian businesses to recover unpaid invoices without wasting time or money.

Why clients don’t pay

Understand the difference between can’t pay and won’t pay:

• Cash flow issues — the client has the intention but not the funds right now
• Dispute over quality — they claim the work was defective or incomplete
• Administrative delay — large organisations with slow payment cycles
• Deliberate avoidance — they never intended to pay and are now ghosting you

The first category might respond to a payment plan. The second needs evidence and negotiation. The third needs persistent follow-up. The fourth needs immediate legal escalation.

A client who won’t pay has already damaged the relationship. Your job is to recover what you are owed.

Step 1: Friendly follow-up (Days 1-14 after due date)

Start with the assumption of good faith. Send a polite reminder email within 7 days of the missed payment date.

What to include:

• Invoice number and amount
• Original due date
• Payment methods available
• Clear call to action: “Please confirm payment by [specific date]”

Keep it brief and professional. Do not apologise for chasing payment.

If you receive no response within 7 days, send a second follow-up with more direct language:

“Our records show invoice [number] for $[amount] remains unpaid. If there is a dispute regarding the work completed, please contact me immediately so we can resolve it. Otherwise, please arrange payment by [date].”

When to move to Step 2:

• No response after two follow-up emails
• Client acknowledges the debt but keeps delaying without offering a payment plan
• Client disputes the invoice without providing specific reasons
• 14 days have passed since the original due date

Step 2: Formal letter of demand (Days 15-35)

A letter of demand is a formal written notice that you intend to take legal action if payment is not received. It demonstrates that you have taken reasonable steps to recover the debt before escalating to tribunal or court.

What a letter of demand must include:

• Your details and the debtor’s details
• Description of the services provided
• Invoice number, date, and amount owing
• Payment due date and the fact it has passed
• Demand for payment within a specific timeframe (typically 7-14 days)
• Statement of intention to commence legal proceedings if payment is not received
• Reference to the legal basis for your claim

How to send it:

Registered post is the gold standard. Email is acceptable if you have been communicating by email throughout the engagement, but registered post creates a paper trail that tribunals recognise.

Most clients pay after receiving a properly drafted letter of demand. It signals that you are serious and that continued avoidance will result in legal costs, tribunal fees, and potential damage to their credit rating.

When to move to Step 3:

• The deadline in your letter of demand has passed with no payment
• The client responds disputing the debt but provides no evidence
• The client offers an unrealistic payment plan (e.g., $10 per month on a $5,000 debt)
• You are confident the debt is valid and you have evidence to prove it

Step 3: Tribunal application (Day 36+)

If the letter of demand does not result in payment, your next step is a formal tribunal application. In Australia, small claims tribunals typically handle debts up to $10,000-$25,000 depending on the state.

Which tribunal:

• NSW: NSW Civil and Administrative Tribunal (NCAT)
• VIC: Victorian Civil and Administrative Tribunal (VCAT)
• QLD: Queensland Civil and Administrative Tribunal (QCAT)
• WA: Magistrates Court (small claims)
• SA: South Australian Civil and Administrative Tribunal (SACAT)
• TAS: Magistrates Court (small claims)
• ACT: ACT Civil and Administrative Tribunal (ACAT)
• NT: Local Court (small claims)

What you need to prepare:

• Completed application form (available on the tribunal website)
• Copy of the original contract or engagement agreement
• Copy of the invoice(s)
• Evidence the work was completed (photos, emails, delivery receipts)
• Copy of your letter of demand and proof it was sent
• Any correspondence with the client
• Filing fee (typically $50-$200 depending on the claim amount)

The tribunal process:

1. You file the application and pay the fee
2. The tribunal serves the application on the debtor
3. The debtor has 28 days to file a response
4. If they do not respond, you can apply for a default judgment
5. If they do respond, the matter is listed for a hearing
6. Both parties attend the hearing and present evidence
7. The tribunal member makes a binding decision

Most tribunal hearings are informal. You do not need a lawyer, but you do need to be organised and present your evidence clearly.

If you win:

The tribunal issues an order requiring the debtor to pay. If they still do not pay, you can typically enforce the order through:

• Garnishee of wages or bank accounts
• Seizure and sale of property
• Registration of a judgment debt on their credit file

Common mistakes to avoid

Waiting too long: The longer you wait, the harder it is to recover the debt. Clients who owe money for 6 months are far less likely to pay than clients who owe money for 6 weeks.

Being too aggressive too soon: Do not send a letter of demand on day 1. Give the client a reasonable opportunity to pay before escalating.

Poor record-keeping: If you cannot prove the work was done, you cannot win at tribunal. Keep emails, photos, timesheets, and signed agreements.

Ignoring disputes: If the client raises a legitimate concern about the quality of your work, address it. Tribunals will not award you the full amount if the work was genuinely defective.

Giving up after the letter of demand: Many service providers send a letter of demand and then do nothing when it is ignored. If you are not prepared to follow through to tribunal, do not send the letter in the first place.

When to write off the debt

Sometimes the debt is not worth pursuing:

• The debtor is bankrupt or insolvent
• The amount is less than $500 and the debtor is interstate
• You have no evidence the work was completed
• The debtor has a genuine dispute and you know your work was substandard

In these cases, write off the debt, learn the lesson, and tighten your processes for next time. Require deposits, use milestone payments, and include clear payment terms in every contract.

Frequently Asked Questions

How long should I wait before sending a letter of demand?

Send at least two polite follow-up emails first. If you receive no response or payment within 14 days of the original due date, escalate to a formal letter of demand. Waiting longer reduces your chances of recovery.

Can I add interest to an unpaid invoice in Australia?

Yes, if your original contract or invoice terms included an interest clause. Without a written agreement, you cannot unilaterally add interest. You can, however, claim tribunal filing fees and enforcement costs if you win your case.

What if the client disputes the quality of my work?

Address the dispute directly. Ask for specific details of what they claim is defective. If the complaint is legitimate, offer to remedy the work or negotiate a reduced payment. If it is a delaying tactic, document your response and proceed with the letter of demand.

Do I need a lawyer to go to tribunal?

No. Small claims tribunals are designed for self-representation. You need to be organised, bring all your evidence, and present your case clearly. For high-value or complex disputes, consider getting legal advice.

What happens if I win at tribunal but the client still won't pay?

You can enforce the tribunal order through garnishee of wages or bank accounts, seizure and sale of property, or registration of a judgment debt on their credit file. Enforcement options vary by state but are available in all Australian jurisdictions.
