To recover a commercial debt in Australia, businesses should prepare the original invoice, signed contract or purchase order, proof that goods or services were supplied, payment terms, account statements, and records of payment reminders or correspondence with the debtor. If the customer disputes the debt, supporting documents such as delivery records, approved quotations, timesheets and written acknowledgements can help establish what was agreed and what remains unpaid. Having these records organised makes it easier for a debt collection agency to assess the claim and determine the next steps.
For businesses dealing with overdue invoices in Perth and across Western Australia, missing paperwork does not always mean a debt cannot be recovered. However, clear records can help resolve questions about the amount owed, the agreed payment date and whether the customer has a valid reason for withholding payment.
1. Original Invoices and Outstanding Account Statements
Invoices are among the most important documents in commercial debt recovery. They identify the amount charged, the goods or services provided and the payment deadline.
Prepare copies of:
- The original unpaid invoice or invoices
- The invoice numbers and dates issued
- The payment due dates
- Any credit notes, adjustments or revised invoices
- An up-to-date statement of account showing the outstanding balance
- Records of any part-payments received
Check that the invoice details are accurate and consistent with your accounting records. If several invoices remain unpaid, provide a schedule showing each invoice, its original amount, payments received and the balance outstanding.
For example, if a customer owes money on four invoices, a clear account statement can help distinguish the total debt from individual overdue amounts.
2. Signed Contracts, Purchase Orders and Agreed Terms
A contract helps establish the commercial agreement between your business and the customer. It may explain what was supplied, the price, payment terms and any conditions relevant to the debt.
Useful documents include:
- Signed service agreements or supply contracts
- Purchase orders issued by the customer
- Accepted quotations or proposals
- Written approvals for additional work
- Credit application forms
- Written trading terms and conditions
- Emails confirming the agreed price, scope of work or payment arrangements
A signed contract is useful, but it is not the only possible evidence of an agreement. Depending on the circumstances, emails, text messages, purchase orders and other business records may help establish the terms of a transaction.
If the customer claims that different payment terms applied, these records can help clarify what both parties agreed to.
3. Proof That Goods or Services Were Supplied
An invoice shows what your business charged, but additional evidence may be needed to demonstrate that the customer received the goods or services.
Depending on your industry, prepare documents such as:
- Delivery dockets and signed delivery receipts
- Freight or shipping records
- Job completion reports
- Timesheets and work logs
- Service reports
- Installation or inspection records
- Customer acceptance forms
- Emails confirming that work was completed
- Relevant photographs or project records
For a supplier, a signed delivery docket may help show that goods were delivered. For a contractor or professional service provider, approved timesheets, completion reports or emails confirming the work may be more relevant.
Choose evidence that directly relates to the unpaid invoice. The goal is to make it straightforward to understand what your business provided and why payment is due.
4. Payment Terms and Credit Application Records
Payment terms help establish when the debt became overdue. They can also be important when determining whether interest or recovery costs may be claimed.
Provide any documents that show:
- The agreed payment period, such as 7, 14 or 30 days
- The date payment became due
- Any agreed credit limit
- Approved changes to payment terms
- Any written arrangement to extend the due date
- Contractual provisions relating to interest or recovery costs
If your business supplied goods or services on credit, include the original credit application and the terms accepted by the customer.
Do not assume that interest, late fees or debt recovery costs can automatically be added to the outstanding balance. Whether these amounts are recoverable depends on the agreement and applicable law.
5. Emails, Letters and Payment Reminder Records
Communication records can help show that your business attempted to resolve the overdue account before escalating the matter.
Gather copies of:
- Initial payment reminders
- Follow-up emails and overdue notices
- Final payment requests
- Letters of demand, if already issued
- Emails discussing the outstanding balance
- Written responses from the customer
- Records of agreed payment dates
- Notes of relevant telephone conversations
Keep the dates and details of important conversations wherever possible. If the customer promised to pay by a particular date, retain any written confirmation of that promise.
These records may help clarify whether the customer acknowledged the debt, requested extra time, raised a dispute or stopped responding to payment requests.
6. Records of Payments and the Remaining Balance
Before referring a commercial debt for recovery, reconcile the account to make sure the amount claimed is correct.
Prepare:
- Bank transaction records relating to payments received
- Receipts issued to the customer
- Remittance advice provided by the debtor
- Credit notes and refunds
- Records of disputed charges or adjustments
- A calculation of the current outstanding balance
This is particularly important when a customer has made partial payments against several invoices.
For example, if a customer has paid part of an invoice but your accounting system still shows the original amount, the balance should be corrected before further recovery action is taken.
Accurate figures reduce confusion and help prevent disagreements about how much remains owing.
7. The Debtor’s Correct Business Details
Providing accurate debtor information helps ensure that recovery correspondence is directed to the correct person or business.
Collect as much of the following information as you have:
- Full legal business or company name
- Trading name, if different
- Australian Business Number (ABN), if available
- Australian Company Number (ACN), where applicable
- Registered or business address
- Trading address, if different
- Business telephone number
- Business email address
- Name and position of the person who placed the order or approved the work
A trading name may not be the same as the legal entity that owes the money. Checking the correct business details can help avoid pursuing the wrong party.
If the customer has changed its business name, moved premises or stopped trading, include any records you have about those changes.
8. Documents Needed When a Customer Disputes the Debt
A commercial debt may become more complicated if the customer claims that the goods were defective, the work was incomplete, the invoice was incorrect or the agreed price was different.
In these situations, provide documents that help explain the disagreement, including:
- The original scope of work or specification
- Approved variations or change requests
- Inspection and quality reports
- Complaints received from the customer
- Your responses to those complaints
- Evidence of repairs, replacements or remedial work
- Emails discussing the disputed amount
- Records of any agreed settlement or adjustment
Do not omit relevant correspondence simply because it contains a complaint. A complete record helps identify which amounts are disputed and which, if any, remain undisputed.
Where a genuine contractual or quality dispute exists, legal advice or dispute resolution may be appropriate before deciding on further recovery action.
9. A Checklist Before Referring a Commercial Debt
Use this checklist to organise your records before contacting a debt collection agency.
- Original invoices and current statement of account
- Contract, purchase order or accepted quotation
- Proof that goods or services were supplied
- Agreed payment terms and credit application
- Payment reminders and relevant correspondence
- Records of part-payments, credits and adjustments
- Correct debtor business details
- Notes of promises to pay or payment arrangements
- Documents relating to any dispute
- Details of any previous recovery action or legal proceedings
You may not need every document for every debt. The relevant evidence depends on the type of transaction, the amount owed and whether the customer disputes the claim.
If some records are missing, explain what is unavailable and provide alternative evidence where possible. Do not create or alter documents to fill gaps.
Can a Commercial Debt Be Recovered Without a Signed Contract?
Yes, a missing signed contract does not automatically prevent a business from pursuing an unpaid commercial debt. The agreement may be evidenced by other records, depending on the circumstances.
For example, an accepted quotation, purchase order, email exchange, delivery receipt or record of completed work may help demonstrate that the customer ordered and received goods or services.
The strength of the claim depends on the available evidence and any issues raised by the customer. If the agreement or amount owed is disputed, professional advice may help you assess the available options.
What Happens After You Submit the Documents?
Once the relevant records are assembled, the next steps generally include:
- Reviewing the account: Check the invoices, outstanding balance, payment terms and supporting evidence.
- Confirming debtor details: Identify the correct business or legal entity responsible for the debt.
- Assessing the recovery options: Consider previous contact, any dispute and the age of the debt.
- Contacting the debtor: Follow an appropriate recovery process based on the circumstances.
- Considering further action: If informal recovery efforts are unsuccessful, a letter of demand, dispute resolution or legal advice may be appropriate.
A debt collection agency can help businesses manage the recovery process, but recovery is not guaranteed. The outcome depends on factors such as the evidence, the debtor’s circumstances and whether the debt is genuinely disputed.

Frequently Asked Questions
What is the most important document for commercial debt recovery?
The unpaid invoice is usually a key document because it identifies the amount claimed and the payment due date. However, a contract, purchase order or other evidence of the agreement, together with proof of supply, can be equally important when establishing the basis of the debt.
Do I need a signed contract to recover an unpaid business invoice?
Not necessarily. Emails, accepted quotations, purchase orders, delivery records and evidence of completed work may help establish the agreement. Whether the evidence is sufficient depends on the circumstances.
Can I refer an overdue invoice to a debt collection agency if the customer disputes it?
You can seek advice about a disputed account, but the dispute should be disclosed and relevant records supplied. The appropriate next step depends on the nature of the disagreement and the evidence available.
Should I send original documents to a debt collection agency?
Keep your original records and provide clear copies unless originals are specifically required. Store electronic records securely and maintain backups.
How old can a commercial debt be before I seek recovery?
There is no single answer for every debt. Limitation periods and other deadlines can depend on the type of claim, the relevant state or territory, and the circumstances. Do not delay seeking legal advice if a debt is old or a deadline may be approaching.
What if I have lost some invoices or emails?
Check your accounting software, bank records, customer files, email archives and delivery systems for copies or alternative evidence. Missing documents do not automatically mean a claim is impossible, but gaps may make it harder to establish the amount owed or the terms of the agreement.
