Quick Answer: Invoice chasing is the process of following up on overdue invoices to recover payment. For Australian SMBs, the most effective approach is a structured, multi-step sequence: a pre-due reminder, a day-one overdue email, a week-two escalation, and a final notice — all sent automatically so the business owner stays out of it emotionally.
Invoice chasing is one of those tasks every Australian business owner hates but almost every one of them has to do. You finished the work. You sent the invoice. And then you waited. And waited. Now it is two weeks past the due date, and you are staring at your inbox trying to figure out how to ask for your money without making things awkward.
Sound familiar? You are not alone. As of early 2026, the average Australian small business invoice is paid more than six days late, according to Xero Small Business Insights. Multiplied across an entire client base, that is a significant amount of cash sitting outside your business when you need it.
The good news is that effective invoice chasing is not about being pushy or aggressive. It is about having a system. A clear, consistent, professional process that runs automatically and gets results without requiring you to write another “just following up” email ever again. For a broader look at how reminder sequences work, the invoice reminders guide for Australian small businesses covers the full setup. And if SMS is part of your strategy, see our guide to SMS payment reminders.
This guide gives you exactly that system.
Key Takeaway: Invoice chasing is not about being aggressive. It is about being consistent. A structured, automated sequence is far more effective than sporadic, emotional follow-ups.
Why Invoice Chasing Feels So Hard
Before diving into the solution, it helps to understand why invoice chasing feels so difficult in the first place. For most Australian small business owners, the awkwardness comes from two sources.
The relationship risk. You built a connection with this client based on your expertise and the quality of your work. Now you have to shift into collections mode, which feels like a completely different dynamic. You worry that following up too aggressively will cost you a future project or a referral.
The time drain. Even when you push past the awkwardness, chasing invoices takes real time. Writing personalised follow-ups, tracking which invoices are overdue, deciding when to escalate — it all adds up. The Australian Small Business and Family Enterprise Ombudsman (ASBFEO) consistently identifies invoice administration as one of the biggest productivity drains on Australian SMBs.
The solution to both problems is the same: remove yourself from the process. When invoice chasing is handled by an automated system rather than by you personally, the relationship dynamic stays intact and the time drain disappears.
Key Takeaway: The awkwardness of invoice chasing comes from mixing personal relationships with financial transactions. Automation removes you from the equation and makes follow-ups feel routine rather than confrontational.
The 5-Stage Invoice Chasing Sequence
A professional invoice chasing system follows a clear, escalating sequence. Each stage is slightly firmer than the last, and the whole thing runs automatically. Here is how it works.
Stage 1: Pre-due reminder (3 days before due date). Send a short, friendly email a few days before the invoice is due. The tone is helpful, not demanding. Something like: “Just a heads-up that invoice #1247 for $3,500 is due on Friday. Let us know if you have any questions.” This single email prevents a large number of invoices from ever becoming overdue. Many clients simply forget, and a timely nudge is all they need.
Stage 2: Due-date notice (day of due date). On the day the invoice is due, send a brief confirmation: “A reminder that invoice #1247 for $3,500 is due today. You can pay by bank transfer using the details on the invoice.” Keep it factual and professional. No emotion, no judgement.
Stage 3: First overdue follow-up (7 days overdue). If the invoice is still unpaid after a week, send a firmer reminder. Acknowledge that they may have missed the earlier notices and ask them to pay or get in touch if there is an issue. Include the invoice details and the outstanding amount.
Stage 4: Second overdue follow-up (14 days overdue). At two weeks overdue, your tone should be noticeably more direct. Note that the invoice is now significantly overdue and that continued non-payment may result in additional action. If you have a late payment fee clause in your terms, mention it here.
Stage 5: Final notice (21 days overdue). This is your final email reminder before escalating to a phone call or formal letter. State clearly that this is a final notice, outline the outstanding amount, and give a specific deadline for payment. Keep it professional but firm.
After stage five, if there is still no response, it is time to pick up the phone. A direct conversation often resolves the issue faster than any number of emails.
Key Takeaway: A five-stage invoice chasing sequence — starting before the due date and escalating gradually — catches most late payments before they become serious problems. Consistency across every client is the key.
What Makes an Invoice Chasing Email Actually Work
The difference between an invoice chasing email that gets a response and one that gets ignored often comes down to three things.
Specificity. Always include the invoice number, the amount outstanding, and the original due date. Do not make the client hunt for this information. The easier you make it to understand what is owed and when, the faster they will act.
A clear call to action. Every reminder should include one clear action: pay the invoice. Include the payment details directly in the email — bank account number, BSB, and any reference number. Removing friction from the payment process is one of the most effective ways to speed up payment.
A single-sentence escalation warning (from stage 3 onwards). Starting at the first overdue notice, include a brief mention of what happens if payment is not received: late fees apply, work may be paused, or the matter may be referred for further action. You do not need to be threatening. Just factual. A simple “Please note that a late payment fee of 2% per month applies to invoices unpaid after 30 days” is enough.

Key Takeaway: Effective invoice chasing emails are specific, include clear payment details, and escalate gradually. Removing friction from the payment process — by including bank details in every email — is one of the most effective ways to speed up payment.
Automating Your Invoice Chasing
Running a five-stage sequence manually is theoretically possible. In practice, it almost never happens consistently. You get busy, you forget, you let a few invoices slide because you have a relationship with the client. Before you know it, you have a stack of 60-day overdue invoices and a cash flow problem.
This is exactly the problem that invoice chasing automation is designed to solve. A tool like Wren connects directly to your Xero account, monitors your invoices in real time, and sends your reminder sequence automatically. You set it up once — your templates, your timing, your tone — and the system handles every invoice from that point forward.
Every client gets the same professional treatment. No one gets forgotten because you were busy. No one gets chased with a frustrated tone because you had a bad week. The reminders go out consistently, professionally, and automatically.
The other major benefit of automation is what it does to the client relationship. When your client receives an automated reminder, it does not feel personal. It feels like a routine system notification, like a bank statement or a utility bill. Nobody gets upset at their bank for sending a credit card payment reminder. The same principle applies to automated invoice reminders.
If you use Xero, our guide to Xero invoice reminders explains how to set up the built-in reminder feature. For a more powerful, customisable solution that works across multiple accounting platforms, Wren gives you full control over your sequence, your templates, and your timing.
Key Takeaway: Manual invoice chasing is inconsistent by design. Automation guarantees that every invoice gets followed up on time, every time, with the same professional tone. It also depersonalises the process, which protects your client relationships.
When to Escalate Beyond Email
Most overdue invoices are resolved within the first two or three reminders. But some are not. When your entire email sequence produces no response, it is time to escalate beyond email.
Phone call. A direct phone call is far harder to ignore than an email. It is also more human, which can help you understand what is actually going on. Maybe the client has a genuine cash flow problem of their own. Maybe there was an issue with the work that was never communicated. A conversation can resolve things that emails cannot.
Formal letter of demand. If phone calls are also ignored, send a formal letter of demand via registered post. This creates a paper trail and signals that you are prepared to take formal action. Many clients who ignore emails will respond to a formal letter.
Debt collection or small claims. For larger debts, engaging a licensed debt collector or filing a claim with a state small claims tribunal is an option. According to ASIC’s debt collection guidelines, all collection activity must be fair, respectful, and accurate. This step will almost certainly end the client relationship, so weigh the amount against the cost.
Key Takeaway: Email covers most invoice chasing situations. When email fails, escalate to phone, then formal letter, then formal action. Document every step so you have a clear record if the matter goes further.
Frequently Asked Questions
How long should I wait before chasing an overdue invoice in Australia?
Do not wait. Send your first overdue reminder the day after the due date. The longer you wait, the harder the conversation becomes and the lower the chance of prompt payment. A day-one overdue email signals that you are on top of your accounts and expect to be paid on time. Better still, send a pre-due reminder a few days before the due date to catch forgetful clients before the invoice ever becomes overdue.
Is invoice chasing legal in Australia?
Yes. You have every legal right to follow up on unpaid invoices. Under the ACCC and ASIC’s joint debt collection guideline, all collection communications must be factual, respectful, and non-harassing. Persistent, professional follow-up via email or phone is entirely lawful. What you cannot do is harass, threaten, or mislead a client to obtain payment.
Can I charge interest on overdue invoices in Australia?
Yes, you can charge late payment fees or interest on overdue invoices if the terms were agreed upon in your contract before the work began. A fee of 1.5% to 2% per month on the outstanding balance is standard and unlikely to be challenged. For the full legal breakdown, see our guide to late payment fees in Australia.
What is the best invoice chasing software for Australian businesses?
The best invoice chasing tool is one that integrates directly with your accounting software so you are not manually tracking invoice status. Wren connects to Xero and allows you to set up a fully automated reminder sequence with custom email templates. It monitors invoice status in real time and stops reminders automatically when an invoice is paid — so you never send a follow-up on a settled account.
How do I chase invoices without damaging the client relationship?
The best way to protect your client relationships while chasing invoices is to remove yourself from the process. Automated reminders feel professional and routine rather than personal and confrontational. When the reminder comes from “the system” rather than from you directly, the dynamic stays intact. For direct communications at the escalation stage, focus on solving the problem together rather than assigning blame.
Key Takeaway: Invoice chasing does not have to be awkward. A systematic, automated approach protects your client relationships, saves your time, and gets you paid consistently. Set it up once and let the system do the work.
The Bottom Line
Invoice chasing is a standard business function, not a personal confrontation. The businesses that get paid consistently are not the most aggressive — they are the most systematic. A five-stage reminder sequence, running automatically, with professional templates and consistent timing, will recover more invoices than any amount of manual chasing.
Set clear payment terms from the start. Automate your reminders. Escalate methodically when needed. And use the right tools to make it all happen without your direct involvement.
