How do I chase up invoices that customers haven't paid without being rude?

Chasing money is the part of running a trade business nobody enjoys. You have done the work, the invoice has gone out, and now you are waiting. The good news: most late payers are not dodging you. They forgot, they are busy, or the invoice slipped past their partner. A short, well timed reminder almost always gets the job done.

Why tradies lose money on invoices they never chase

The real cost of an unpaid invoice is not just the dollar amount. It is the time you spend thinking about it, the cash flow gap it opens while you are paying suppliers and subbies on time, and the jobs you hesitate to quote because you are not sure the last one has been paid. Industry commentary from Australian trade accounting advisors consistently notes that late payment is the single biggest cash flow problem for small trade businesses, and that most overdue invoices are eventually paid once chased, they just need the nudge.

The tradies who collect fastest are not the ones who send angry texts. They are the ones who have a system: a predictable sequence of reminders that runs whether they remember or not. That is the difference between chasing money and having money arrive. For a walkthrough of automating the invoicing and reminder sequence itself, see our guide to automating invoices and payment reminders from your phone.

The three stage follow-up that works

This is a practical sequence you can copy and adjust for your business. The tone stays professional throughout, because the customer you chase well today is the referral source you want tomorrow.

1. Day 7 overdue: the friendly nudge. A short message that assumes the best. Something like: "Hi [name], just a quick one to check invoice [number] for [amount] landed OK. Due date was [date]. Let me know if you need it re-sent. Thanks, [your name]." No pressure, no threat. Most invoices get paid here.
2. Day 14 overdue: the professional reminder. Restate the amount and original due date, note this is a second reminder, and ask if there is anything holding it up. Keep it factual: "I want to get this sorted for both of us." If the customer has a concern about the work, this is where it surfaces, and you want that conversation, not silence.
3. Day 30 overdue: the firm notice. Still polite, but clear about next steps. State the total outstanding, the original due date, and that you will need to consider further action if it remains unpaid. In most states, for debts under $25,000 (directional, check your state's civil claims threshold), you can lodge a claim through the relevant tribunal or small claims court without a lawyer. Mention the option factually, never as a threat.

Each step gives the customer a clear, face saving way to pay. Most will. The small number who do not are handled by your state's dispute resolution pathway, not by an angry phone call that burns the bridge and still does not get you paid.

The wording matters more than you think

A blunt "where's my money" text feels satisfying for about three seconds, then costs you the referral and sometimes the payment itself (a defensive customer is a slow paying customer). The wording principles that work:

• Assume the best. "Just checking this landed" works better than "you haven't paid."
• Be specific. Include the invoice number, the amount and the due date every time. The customer should never have to search for what you are talking about.
• Keep it short. Three to four sentences. A wall of text reads as emotional, not professional.
• One ask per message. "Can you let me know when this is sorted?" is clear. A message that asks about the payment, mentions the next job and flags the warranty all at once gets none of them answered.
• Never threaten legal action loosely. If you reach the stage of mentioning further steps, name the specific pathway (your state's civil and administrative tribunal or small claims court) and the factual threshold. Vague threats of "getting my lawyer onto it" on a modest invoice sound empty and can damage the relationship permanently.

Automate it so you never have to remember

The biggest leak is not wording. It is forgetting to send the reminder at all because you are back on the tools the next morning. The fix is to take yourself out of the loop: set up an automated reminder sequence so the messages go out on schedule whether you remember or not.

Most job management apps used by Australian tradies (ServiceM8, Tradify, simPRO, AroFlo, Fergus) can trigger a basic overdue reminder. For a more tailored sequence, you can wire custom automation around your invoicing tool (Xero, MYOB or QuickBooks) so each stage sends the right message at the right time, with the invoice details populated and the tone matched to your business.

That is the core of what we build at TradieBuddy AI: custom agents that handle the admin you keep meaning to do but never get to, wired into the tools you already run.

When to stop chasing and escalate

Not every invoice gets paid by a reminder. If 30 days pass and there is no response or payment:

• Send a formal letter of demand. A one-page letter restating the debt, the due date, and a final deadline (usually 14 days). You can write it yourself. It signals seriousness.
• Check your state's threshold. Each Australian state and territory has a civil claims or small claims pathway with a dollar limit (directional: typically $25,000 to $40,000 depending on jurisdiction, verify with your state's tribunal). Below that limit you can lodge a claim yourself without a lawyer, and the filing fee is modest.
• Consider a debt collection service. For larger or repeated non-payers, a licensed debt collector can recover the amount, usually on a percentage of what they collect. Check that the collector is licensed in your state and operates under the ACCC debt collection guidelines.

The goal of the three-stage sequence above is to make escalation rare. Most customers pay when the reminder lands on time and the tone stays professional.

Keep the relationship and the cash flow

Chasing invoices well is a business skill, not a confrontation. The tradies who get paid fastest are not aggressive. They are consistent, clear and quick, and most of them have taken themselves out of the loop entirely by automating the follow-up. If you want to see how that works alongside the rest of your admin, the paid AI automation audit maps every operational leak, invoices included, and shows you which ones pay back first.
