Cash flow remains the lifeblood of every Australian business, yet many companies struggle with overdue invoices and ineffective debt collection processes. Implementing a systematic approach to invoice reminders and debtor management can dramatically improve your cash flow while maintaining positive client relationships.
This comprehensive guide provides a complete framework for automating invoice reminders and implementing a professional debtor chasing system that works for Australian businesses of all sizes.
Before diving into solutions, it's crucial to understand the real impact of ineffective invoice management on Australian businesses.
Recent data shows that Australian businesses typically have 25-30% of their invoices overdue at any given time. For a business with $2 million in annual revenue, this could mean $500,000-$600,000 tied up in overdue accounts at any point.
Consider these financial impacts:

Indirect Costs:
Industry research indicates that the likelihood of collecting overdue debts decreases significantly over time:
This data underscores the critical importance of early intervention and systematic follow-up processes.
The most effective approach to debtor management involves a structured, escalating system that balances automation with personal intervention. Here's the proven framework that Australian businesses should implement:
The foundation of your system should begin before invoices become overdue. Most accounting software, including Xero, allows you to set up automated reminder emails.
Implementation Timeline:
Automated Email Content Structure:
First Reminder (14 days overdue):Subject: "Friendly Reminder - Invoice [Invoice Number] Due in [X] Days"
The email should be friendly and professional, assuming the oversight is unintentional. Include the original invoice, payment terms, and multiple payment options.
Second Reminder (30 days overdue):Subject: "Overdue Invoice - [Invoice Number] - Immediate Payment Required"
This email should be more direct while remaining professional. Clearly state the overdue amount and include late payment fees if applicable under your terms.
Third Reminder (45 days overdue):Subject: "URGENT: Overdue Invoice [Invoice Number] - Account on Hold"
This message should indicate that services may be suspended and hint at further collection action if payment isn't received promptly.
For this stage, implement automated workflows through your accounting software. Xero's automated invoicing features allow you to set up personalised email sequences that trigger based on invoice age.
Configuration Requirements:
Email Frequency: Every 7-10 days for invoices in this range

Days Sales Outstanding (DSO):
DSO = (Average Accounts Receivable ÷ Total Credit Sales) × Number of Days
For a business with $200,000 average receivables and $2,400,000 annual credit sales:DSO = ($200,000 ÷ $2,400,000) × 365 = 30.4 days
Collection Effectiveness Rate:
Collection Rate = (Collections in Period ÷ Receivables at Start of Period) × 100

Avoid these common mistakes when implementing your automated debtor management system.
Problem: Over-reliance on automation without human oversight -> Solution: Maintain regular review processes and human intervention points
Problem: Poor integration between systems leading to data inconsistencies -> Solution: Invest in proper integration or select integrated software suites
Problem: Generic email templates that don't reflect company brand -> Solution: Customise all communications to match company tone and branding
Problem: Inconsistent application of collection procedures -> Solution: Develop written procedures and regular staff training
Problem: Failure to update client contact information -> Solution: Regular data cleansing and client contact verification
Problem: Inadequate documentation of collection activities -> Solution: Mandatory recording requirements and regular audit processes

Q: How quickly can I implement an automated invoice reminder system?
A: Most accounting software like Xero can be configured with basic automated reminders within 24-48 hours. A complete debtor management framework typically takes 2-4 weeks to implement fully, including staff training and process documentation. The key is starting with basic automation and gradually adding sophistication.
Q: What's the optimal timing for sending invoice reminders?
A: Best practice is to send the first reminder 14 days after invoice date (before it becomes overdue), then at 30, 45, and 60 days. After 60 days, switch to personal follow-up every 5-7 days. This timing balances persistence with maintaining professional relationships.
Q: Can I charge interest on overdue invoices in Australia?
A: Yes, but only if your original contract or terms and conditions specify interest charges and the rate. Interest rates must be reasonable and comply with Australian Consumer Law. Typical rates range from 1.5% to 2.5% per month on overdue amounts.
Q: How do I handle clients who consistently pay late but are otherwise valuable?
A: Implement a tiered approach: negotiate shorter payment terms, require deposits or progress payments, consider credit insurance, or factor in late payment costs into your pricing. Document all arrangements in writing and review annually.
Q: What should I do if automated emails aren't working?
A: Check email deliverability first (spam filters, correct addresses). Then analyse your email content - it may be too aggressive or not compelling enough. Consider A/B testing different subject lines and messages. If emails continue to fail, switch to phone calls and registered mail.
Q: When should I write off a debt as uncollectable?
A: Generally, after 6-12 months of active collection efforts with no payment or contact. Consider earlier write-off for amounts under $500 where collection costs exceed the debt value. Always consult your accountant as write-offs have tax implications.
Q: How do I maintain good relationships while chasing overdue payments?
A: Start with the assumption that late payment is unintentional. Use professional, respectful language in all communications. Be flexible with payment arrangements when clients face genuine hardship. Focus on solving the problem together rather than assigning blame.
Q: Can I stop providing services to clients with overdue accounts?
A: Generally yes, if your terms and conditions specify this right. However, consider the total relationship value and whether the client is making efforts to pay. For ongoing service contracts, follow the termination procedures specified in your agreement.
Q: What records should I keep for debt collection activities?
A: Document all communications including dates, times, people spoken to, outcomes, and follow-up actions required. Keep copies of all emails, notes from phone calls, payment arrangements, and any disputes. These records are essential if legal action becomes necessary.
Q: Should I use a debt collection agency?
A: Consider external collection agencies for debts over 90 days old where internal efforts have failed, when you lack internal resources, or for difficult clients. Agencies typically charge 15-30% of collected amounts. Ensure any agency you use follows Australian debt collection guidelines and practices.
