Customer Refuses to Pay After Service Delivered: What to Do Next

You’ve done the work. The service was delivered. The invoice was sent. And now — silence. Or worse, excuses, disputes, or flat-out refusal to pay.

When a customer refuses to pay after service delivered, it’s about your cashflow and the principle that agreements matter. This guide shows you exactly what to do next, with realistic timelines and escalation options that work across Australia.

Why customers refuse to pay

Most non-payment falls into one of these categories:

• Genuine dispute — they claim the work was defective, incomplete, or not what was agreed
• Cashflow problems — they’re broke but won’t admit it
• Bad faith — they never intended to pay, or they’re testing whether you’ll chase
• Communication breakdown — your invoice got lost, sent to the wrong person, or buried in spam

Understanding the reason helps you choose the right response. A genuine dispute might need negotiation. A cashflow issue might need a payment plan. Bad faith needs immediate escalation.

Every day you wait costs you money.

Step 1: Send a final invoice with a clear deadline

Before you escalate, give them one last chance to pay without legal pressure. This shows reasonableness if you end up in tribunal.

What to include:

• Original invoice details (date, amount, description of services)
• Statement that payment is now overdue
• New deadline — 7 days is standard, 14 days if you’re feeling generous
• Payment methods (bank transfer details, payment link if you have one)
• Clear consequence: “If payment is not received by [date], we will commence debt recovery action without further notice”

Timeline: Send this 7-14 days after the original invoice due date.

Delivery method: Email is fine if that’s how you’ve been communicating. For larger amounts or difficult customers, send via registered post as well so you have proof of delivery.

Step 2: Letter of demand — the formal escalation

If the final invoice doesn’t work, the next step is a letter of demand. This is a formal document that states the debt clearly, gives a final deadline (typically 7-14 days), and warns of tribunal or court action if payment is not made.

Why it works:

Many people don’t want a tribunal claim on their record, and businesses don’t want the administrative burden.

What to include:

• Your details and the debtor’s details
• Description of the service provided and when
• Invoice number, date, and amount
• Reference to the contract or agreement (even if verbal)
• Clear demand for payment within 7-14 days
• Statement that failure to pay will result in tribunal or court proceedings

Timeline: Send the letter of demand 7-10 days after the final invoice deadline passes.

How Claim Done helps: Claim Done generates a professionally formatted letter of demand based on the evidence you describe. You complete a 5-minute intake form, tell us about your invoice and any contract or correspondence, and our Programmatic Algorithms draft a letter citing the applicable Australian law. It’s delivered to the debtor by email. Flat fee, done in about 5 minutes.

Step 3: Consider a payment plan (if appropriate)

If the customer responds to the letter of demand but genuinely can’t pay in full, a payment plan might be the fastest way to recover your money without tribunal costs.

When to offer a payment plan:

• The customer admits the debt but has cashflow issues
• You’d rather get paid in instalments than chase them through tribunal
• The relationship is worth preserving (ongoing client, referral source)

What to include in the payment plan agreement:

• Total amount owed
• Instalment amounts and due dates
• What happens if they miss a payment (typically the full balance becomes immediately due)
• Signed by both parties

Claim Done can prepare a formal payment plan agreement for $49. It’s legally binding, clear, and enforceable if they breach it.

Step 4: Tribunal or court claim — small claims

If the letter of demand doesn’t work and you’re not interested in a payment plan, the next step is a claim in your state’s tribunal or court. Which one depends on where you are. In New South Wales, a business owed money has a debt claim for the Local Court, not NCAT:

• New South Wales: Local Court of NSW — Small Claims Division up to $20,000; General Division over $20,000 up to $100,000
• Victoria: Victorian Civil and Administrative Tribunal (VCAT) — Civil Claims List
• Queensland: Queensland Civil and Administrative Tribunal (QCAT) — minor civil dispute, up to $25,000
• Western Australia: Magistrates Court of WA — minor case claims up to $10,000; general procedure claims up to $75,000
• South Australia: Magistrates Court of SA — minor civil action up to $12,000; general claims up to $100,000
• Tasmania: Magistrates Court of Tasmania (Civil Division) — up to $50,000
• Australian Capital Territory: ACT Civil and Administrative Tribunal (ACAT) — civil disputes up to $25,000
• Northern Territory: NT Civil and Administrative Tribunal (NTCAT) — small claims up to $25,000

What you’ll need:

• Completed tribunal application form or court statement of claim
• Copy of your invoice
• Copy of any contract or agreement (even if it’s just email correspondence)
• Copy of the letter of demand you sent
• Evidence the service was delivered (photos, emails, signed delivery notes)
• Proof of attempts to recover the debt

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

How Claim Done helps: Claim Done’s Tribunal Application ($97) drafts your application for the right forum, including a Local Court statement of claim for a New South Wales debt. You tell us what evidence you have, answer a few questions, and our Programmatic Algorithms draft the document citing the applicable law and procedural rules for your state. You approve it, then file it and pay the filing fee yourself.

Step 5: Enforcing the tribunal order

Winning at tribunal doesn’t automatically put money in your bank. If the debtor still refuses to pay, you’ll need to enforce the order. Options include:

• Garnishee order — the court takes money directly from their bank account or wages
• Seizure and sale — a sheriff seizes their assets and sells them to pay the debt
• Payment arrangement — the tribunal can order instalments if the debtor genuinely can’t pay in full

Enforcement costs extra (sheriff fees, court fees), but these can usually be added to the debt.

What NOT to do when a customer refuses to pay

• Don’t harass them — repeated calls, threats, or abusive messages can land you in legal trouble
• Don’t withhold work or access without a contractual right — if your contract doesn’t include a retention of title clause or similar, you can’t just take back what you’ve delivered
• Don’t wait months — the longer you wait, the harder it is to recover
• Don’t skip the letter of demand — tribunals expect you to have attempted recovery before filing

How to prevent non-payment in future

Once you’ve recovered this debt, take steps to reduce the risk next time:

• Require a deposit — 30-50% upfront for new clients or large jobs
• Use a written service agreement — even a simple email confirming scope, price, and payment terms
• Invoice promptly — send the invoice the day the work is completed, not weeks later
• Follow up early — if payment is 7 days late, send a reminder immediately
• Include late payment terms — your contract can specify interest on overdue amounts (typically 10-15% per annum)

Claim Done can prepare a service agreement tailored to your business for $49. It includes payment terms, scope of work, and dispute resolution clauses that make debt recovery easier if things go wrong.

Final checklist: customer refuses to pay after service delivered

1. Day 7-14 after invoice due date: Send final invoice with 7-day deadline
2. Day 21-28: Send letter of demand with 7-14 day deadline
3. Day 35-42: File your tribunal or court claim if no payment or response
4. When it is listed: Attend the hearing
5. After the order: Enforce if necessary

Every step is documented, every deadline is clear, and every escalation is proportionate.

Frequently Asked Questions

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

Send a final invoice 7-14 days after the original due date. If that doesn’t work, send a letter of demand 7-10 days later. Don’t wait months — the longer a debt sits, the harder it is to recover.

What if the customer claims the work was defective?

If they’re genuinely disputing the quality of your work, you may need to negotiate or provide evidence the work met the agreed standard. If the dispute is in bad faith (they’re just avoiding payment), proceed with the letter of demand and tribunal application. Include any evidence showing the work was completed as agreed.

Can I charge interest on overdue invoices?

Yes, if your service agreement or invoice terms include a late payment interest clause. Standard rates are 10-15% per annum. Without a written agreement, you can’t automatically charge interest, but you can claim it as part of your tribunal application.

What happens if the customer ignores the letter of demand?

If they don’t respond or pay within the deadline (typically 7-14 days), your next step is filing a claim in the right tribunal or court for your state (in New South Wales, the Local Court). The letter of demand shows the tribunal you attempted to resolve the matter before escalating, which strengthens your case.

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

No. Even verbal agreements are enforceable in Australia. However, written evidence (emails, text messages, signed quotes, invoices) makes your case much stronger. If you have any correspondence confirming the scope of work and price, that’s usually enough.
