Client Owes You Money But Won’t Respond: Your 3-Step Recovery Process

You’ve done the work. You’ve sent the invoice. You’ve waited. You’ve sent a polite follow-up. Still nothing. Your client has gone silent, and your cash flow is suffering.

Stop sending increasingly desperate emails. You need a structured escalation process that increases pressure at each stage while protecting your legal position. This guide walks you through the three-step recovery process used by thousands of Australian businesses to collect unpaid invoices from non-responsive clients.

Why clients stop responding to invoices

Clients go silent for different reasons, and the reason matters:

Cash flow problems — they can’t pay right now but don’t want to admit it. These clients often respond well to payment plans once you apply formal pressure.

Dispute avoidance — they’re unhappy with the work but won’t articulate it. They hope you’ll give up. These clients need a clear deadline and consequences.

Deliberate non-payment — they never intended to pay. These clients only respond to legal action.

Administrative chaos — your invoice is lost in their system. These clients typically pay quickly once you escalate to someone senior.

The three-step process works regardless of the reason because it systematically removes every excuse and creates a documented trail of your attempts to resolve the matter.

Step 1: The friendly reminder (Days 1-14 after due date)

Start with a brief, professional reminder. Many non-payments are genuinely administrative errors, and you want to preserve the relationship if possible.

What to send:

• Email subject: “Invoice [number] now overdue — [Your Business Name]”
• Attach the original invoice again
• State the amount, due date, and number of days overdue
• Ask for payment within 7 days
• Offer a phone call to discuss any issues

Template opening: “Invoice #1234 for $2,850 was due on 15 March and is now 10 days overdue. I’ve attached a copy for your reference. Please arrange payment by 1 April. If there’s any issue with the invoice, let me know and we can discuss.”

What not to do:

• Don’t apologise for chasing payment
• Don’t offer unsolicited discounts
• Don’t threaten legal action yet
• Don’t send multiple reminders in the same week

If you get no response within 7 days, move to Step 2. Do not wait longer. Every day you delay weakens your position.

Step 2: Formal letter of demand (Days 15-28)

This is where most unpaid invoices get resolved. A properly drafted letter of demand delivered by registered post or email creates immediate pressure. It signals you’re no longer asking nicely — you’re preparing to take legal action.

What the letter must include:

• Your details and the debtor’s details
• Exact amount owed, broken down by invoice
• The work performed or goods supplied
• Payment due date and days overdue
• Legal basis for the claim
• Clear demand for payment within 7-14 days
• Statement of intended action if unpaid (tribunal application)
• Your contact details for payment arrangements

Why it works:

Most clients know that a formal demand letter is the last step before legal action. It forces them to make a decision: pay now, negotiate a payment plan, or defend a tribunal claim. The majority choose to pay rather than face the cost and stress of tribunal proceedings.

Delivery method matters:

Email is acceptable for speed, but registered post creates a paper trail proving delivery. Send both. The registered post receipt becomes evidence if you need to file a tribunal application.

ClaimDone automates this step. Upload your invoice and evidence, answer 5 minutes of questions, and our Proprietary AI Engine drafts a legally precise letter of demand. We deliver it automatically by email and generate a PDF for registered post. Flat fee $79, done in 60 minutes.

Step 3: Tribunal application (Days 29+)

If the letter of demand doesn’t work, you file a tribunal application. You are taking the matter to the relevant state or territory tribunal to obtain a legally enforceable order for payment.

Which tribunal:

• NSW: NSW Civil and Administrative Tribunal (NCAT) — up to $30,000
• VIC: Victorian Civil and Administrative Tribunal (VCAT) — up to $10,000
• QLD: Queensland Civil and Administrative Tribunal (QCAT) — up to $25,000
• WA: Magistrates Court (small claims) — up to $10,000
• SA: South Australian Civil and Administrative Tribunal (SACAT) — up to $12,000
• TAS: Magistrates Court (small claims) — up to $5,000
• ACT: ACT Civil and Administrative Tribunal (ACAT) — up to $25,000
• NT: Local Court (small claims) — up to $25,000

What you need:

• Completed tribunal application form
• Copy of your invoice(s)
• Copy of the contract or agreement (if written)
• Evidence of work performed (photos, emails, delivery receipts)
• Copy of your letter of demand and proof of delivery
• Filing fee (typically $50-$200 depending on claim value and state)

Timeline:

Most tribunals list hearings within 6-12 weeks of filing. The debtor typically has 14-28 days to file a defence. If they don’t defend, you can apply for default judgment without a hearing.

What happens at the hearing:

You present your evidence. The debtor presents theirs. The tribunal member makes a decision on the day or within a few weeks. If you win, you get an order for payment plus your filing fee. If the debtor still doesn’t pay, you can enforce the order through wage garnishment, bank account seizure, or property liens.

ClaimDone prepares your tribunal application. We draft the application, organise your evidence, and prepare a written submission. You file it yourself (tribunals don’t allow representation in small claims). Flat fee varies by state and claim complexity.

Timeline summary: How long does the full process take?

Week 1-2: Friendly reminder sent, 7-day response window

Week 3-4: Letter of demand sent, 7-14 day response window

Week 5: Tribunal application filed if still unpaid

Week 11-17: Tribunal hearing (6-12 weeks after filing)

Total time from first reminder to tribunal order: 3-4 months

Most debts are resolved at Step 2. Only about 10-15% of formal demands proceed to tribunal, and of those, roughly half settle before the hearing once the debtor receives the tribunal notice.

Common mistakes that weaken your recovery

Waiting too long to escalate. Every month you wait reduces your chance of recovery. Debts older than 90 days typically have a 50% lower recovery rate than debts under 30 days.

Sending too many reminders. More than two friendly reminders makes you look desperate and suggests you won’t actually take action.

Offering unsolicited discounts. This signals the debt is negotiable and encourages the client to delay further hoping for a better offer.

Threatening legal action without following through. If you say you’ll file a tribunal claim by a certain date and then don’t, you’ve lost all credibility.

Not keeping records. Every email, every phone call, every delivery receipt matters. If you end up in tribunal, you need to prove you did the work and attempted to collect payment.

When to skip straight to Step 2 or Step 3

You don’t always need to follow the full three-step process. Skip the friendly reminder and go straight to a formal demand if:

• The invoice is more than 60 days overdue
• You’ve already sent multiple reminders with no response
• The client has a history of non-payment
• The amount is substantial (over $5,000)
• The client has indicated they dispute the work but won’t engage in resolution

Skip straight to tribunal if:

• The client has explicitly refused to pay
• The debt is over 90 days old with no engagement
• You’ve sent a demand letter and the deadline has passed with no response
• The client is showing signs of insolvency (closing down, selling assets)

Frequently Asked Questions

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

Send a friendly reminder 7-14 days after the due date. If there’s no response within 7 days of that reminder, send a formal letter of demand. Don’t wait longer than 30 days past the due date to escalate to a formal demand — every week you delay reduces your chance of recovery.

Can I charge interest on an overdue invoice?

Yes, if your contract or terms and conditions specify an interest rate for late payment. Without a written agreement, you typically can’t automatically charge interest, but you can include reasonable interest in your tribunal claim. Most businesses include a late payment clause in their standard terms.

What if the client claims they're unhappy with the work?

If they raise a genuine dispute after receiving your demand letter, you need to address it before filing a tribunal application. Ask them to specify in writing what the issue is and what they consider a fair resolution. If they refuse to engage or their complaint is vague, proceed with the tribunal application — the tribunal will assess whether the dispute is legitimate.

Do I need a lawyer to file a tribunal application?

No. Small claims tribunals are designed for self-representation. In most states, lawyers aren’t even allowed to represent you in small claims matters. You present your own case, and the tribunal member will guide the process. ClaimDone prepares your application and written submissions, but you file and attend the hearing yourself.

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

You can enforce the tribunal order through several methods: wage garnishment (if they’re employed), bank account seizure, property liens, or appointing a sheriff to seize assets. Each state has different enforcement procedures. Most debtors pay once they receive the tribunal order because enforcement can result in additional costs and damage to their credit rating.
