If a customer in Perth has not paid an invoice by the agreed due date, start by checking the payment terms and invoice details, then follow up with a clear payment request. If repeated reminders do not result in payment, or the customer stops responding, professional debt recovery may be the next practical step. Acting promptly can help businesses reduce the time and resources spent chasing overdue accounts.
Unpaid invoices are a common challenge for businesses. Whether you run a trade business, professional service, childcare business, telecommunications company or another commercial operation, outstanding invoices can put unnecessary pressure on cash flow.
The important thing is to have a clear process for dealing with overdue accounts rather than allowing them to remain unresolved.
For Perth businesses, this guide explains the practical steps you can take when a customer fails to pay an invoice.
Step 1: Check the Invoice and Payment Terms
Before contacting the customer, make sure the invoice is accurate.
Check:
- Customer or business name
- Invoice number
- Invoice date
- Amount owing
- Payment due date
- Payment instructions
- Description of goods or services
- Applicable payment terms
- Purchase order or agreement details
Also check whether the customer has already made a partial payment.
An incorrect invoice can create an unnecessary delay. Confirming the details first gives you a clear position before beginning the recovery process.
Step 2: Confirm There Is No Genuine Dispute
Not every unpaid invoice is simply a refusal to pay.
The customer may believe:
- The invoice amount is incorrect
- The agreed price was different
- The goods were not delivered as expected
- Services were incomplete
- There was an issue with the quality of the work
- A credit or adjustment was expected
If the customer has raised an issue, investigate it before treating the account purely as a collection matter.
Keep records of any dispute and your response.
If there is no genuine dispute and the payment is simply overdue, you can proceed with your normal payment follow-up process.
Step 3: Send a Clear Payment Reminder
Once you have confirmed that the invoice is overdue, contact the customer.
Your reminder should clearly state:
- Invoice number
- Original invoice amount
- Amount currently outstanding
- Original due date
- Requested payment date
- Payment method or instructions
- Contact details for questions
Keep the communication professional and factual.
A simple reminder can sometimes resolve an overdue account when the customer has forgotten the invoice or overlooked it within their accounts system.
Step 4: Follow Up if Payment Is Still Outstanding
If the customer does not respond to the first reminder, follow up.
Depending on your internal process, this may include:
- Email follow-up
- Telephone call
- Additional written reminder
- Confirmation of the outstanding balance
- Request for a specific payment date
Keep records of every attempt.
Documenting your communication gives your business a clear history of what has happened with the account.
Step 5: Set a Clear Point for Escalation
One of the biggest problems businesses face with unpaid invoices is repeatedly saying, “We’ll follow up again next week.”
Without a defined escalation point, an overdue invoice can remain outstanding for months.
Consider establishing an internal process such as:
Payment due → Reminder → Follow-up → Final internal review → Professional debt recovery
The timing will depend on your payment terms and the circumstances of the account.
The important point is to know when internal chasing has stopped being productive.
Step 6: Consider Professional Debt Recovery
If repeated payment requests have not worked, professional debt collection may be an option.
A debt collection agency can take over communication with the debtor and manage the recovery process on behalf of your business.
This can be particularly useful when:
- The invoice is significantly overdue
- The debtor has stopped responding
- Your staff are spending too much time chasing payment
- You have multiple overdue accounts
- The outstanding amount is affecting cash flow
- You want an external party to manage the recovery process
For Perth businesses, professional debt recovery can provide a structured approach to dealing with overdue commercial accounts.
Why Businesses Should Not Ignore Unpaid Invoices
It can be tempting to leave a small unpaid invoice alone, particularly when the business is busy.
But several overdue invoices can quickly become a significant amount of money.
For example:
| Situation | Potential business impact |
| One overdue invoice | Delayed expected income |
| Several overdue invoices | Increased pressure on cash flow |
| Regular late payments | More administrative work |
| Unresolved aged accounts | Greater uncertainty over receivables |
| Staff repeatedly chasing payments | Lost productive time |
For this reason, businesses should regularly review their accounts receivable and identify invoices that require further action.
How Much Time Does Your Business Spend Chasing Unpaid Invoices?
Debt recovery is not only about the money owed.
There is also the cost of repeatedly pursuing payment.
Someone in your business may need to:
- Check the account
- Send emails
- Make phone calls
- Record conversations
- Resend invoices
- Follow up on promised payments
- Update accounting records
- Contact the customer again when payment does not arrive
For a small business, this can take valuable time away from customers and day-to-day operations.
Professional debt collection can allow your internal team to spend less time on repetitive recovery activity.
What Should You Keep Before Referring an Unpaid Invoice?
Good documentation can make the recovery process more straightforward.
Keep copies of:
- Original invoices
- Contracts or agreements
- Purchase orders
- Quotes
- Terms and conditions
- Proof of delivery
- Timesheets or service records
- Emails and other correspondence
- Payment reminders
- Notes from telephone conversations
- Records of payments already received
You should also make sure the debtor’s contact information is as accurate and current as possible.
Can Debt Collection Help With Business-to-Business Debts?
Yes. Businesses can seek professional assistance with eligible commercial debts where customers or other businesses have failed to pay according to agreed terms.
Commercial debt recovery may involve accounts arising from goods supplied, services provided or other business transactions.
The specific circumstances and documentation should always be reviewed before recovery action is taken.
What If the Customer Promises to Pay?
A promise to pay is useful only if the payment actually arrives.
If a customer agrees to pay on a particular date, record the agreement and monitor the account.
If the promised payment does not arrive, follow up promptly rather than allowing another lengthy delay.
Repeated broken payment promises can be an indication that the account requires escalation.
When Should a Perth Business Stop Chasing an Invoice Internally?
There is no universal number of days that applies to every overdue account.
However, businesses should consider escalating an account when:
- The agreed payment date has passed
- Reminders have already been sent
- Telephone calls have not resolved the issue
- The customer has stopped responding
- Promised payments have been missed
- The balance is becoming significantly overdue
- Internal collection efforts are consuming too much time
The earlier a business establishes a consistent recovery process, the easier it can be to manage overdue accounts.

Frequently Asked Questions
How long should an invoice be overdue before I use a debt collection agency?
There is no single timeframe that applies to every invoice. Consider the agreed payment terms, age of the debt, previous communication, documentation and whether there is a genuine dispute.
Can I use a debt collection agency for an unpaid business invoice?
Businesses can seek professional assistance with eligible unpaid commercial invoices. The account should be assessed based on its circumstances and supporting documentation.
What should I do if my customer refuses to pay an invoice?
First, establish why the customer is refusing payment. Check whether there is a genuine dispute and review the relevant agreement, invoice and supporting records. If the account remains unpaid after reasonable attempts to resolve the matter, professional debt recovery may be an option.
Should I keep contacting the customer myself?
You can establish your own internal payment follow-up process. However, if repeated attempts are taking significant staff time without producing payment, you may wish to consider professional debt collection.
What information does a debt collection agency need?
Typically, useful information includes the debtor’s details, outstanding invoice, amount owing, payment terms, agreement or contract, supporting documentation and records of previous communication.
Can an old unpaid invoice still be recovered?
An older debt may still have recovery options, but the circumstances and applicable legal requirements need to be considered. Businesses should not assume that an old account is automatically recoverable or automatically unrecoverable.
How do I start recovering an unpaid invoice in Perth?
Gather your invoice and supporting documentation, confirm the amount outstanding and review your previous communication with the customer. You can then contact National Collections to discuss the account and available recovery options.
Do You Have an Unpaid Invoice?
