Late payments are one of the most consistent frustrations for Australian small business owners. The work is done, the invoice is sent, and then nothing. A week passes. Two weeks. You write a polite reminder. Another week. You write a less polite one. It is time-consuming, it is awkward, and it should not require your personal attention at all.
The good news is that most of this can be automated. Not in a way that feels cold or aggressive, but in a structured sequence that sends the right message at the right time and escalates only when a human actually needs to get involved.
Here is how it works.
What Xero already gives you
Xero has a built-in invoice reminder feature. You can turn it on under Accounts, then Sales, then Invoice Reminders. It lets you set up to three reminder emails at intervals you define, like "send three days before due, on the due date, and seven days overdue."
For straightforward businesses with consistent payment terms, this covers a lot of ground. The reminders go out automatically, they reference the invoice, and they include a link to the payment portal if you use Xero's online payments.
The limitation is that the messages are generic. Every client gets the same email, regardless of whether they are a long-term client who always pays within a week, a new client who might need extra guidance, or a problem account that needs firm language. There is also no branching logic: if a client pays, Xero stops sending reminders. But if a payment is made late or in the wrong amount, the built-in reminders do not flag it for you.
What a proper automated sequence looks like
A more complete invoice follow-up sequence adds a layer of intelligence on top of Xero's built-in reminders. The typical setup looks like this:
Day 0 (invoice sent): Xero sends the invoice. A confirmation email goes to the client with clear payment instructions and a link to the invoice.
Day minus 3 (before due date): A friendly reminder that payment is due in three days. Short, warm, no pressure. This one prevents the most common reason for late payment: the client simply forgot.
Day 1 (one day overdue): A direct but professional follow-up. Something like: "Your invoice from [date] for $X is now one day overdue. If there is a problem with the invoice, please let us know. Otherwise, a link to pay is below." No apology, no aggression.
Day 7 (one week overdue): A firmer message. Acknowledgement that this is now a week past due, a request for an update by a specific date, and a note that you may need to pause work if payment is not received.
Day 14 (two weeks overdue): An internal notification to your phone or team channel. At this point, a human should call. Automated emails alone rarely resolve a genuinely difficult payment situation.
The sequence stops the moment the invoice is marked as paid in Xero.
Connecting Xero to your automation platform
Xero has a well-documented API and connects to most automation platforms, including Make.com and Power Automate. The typical approach is:
- Set a trigger: watch for invoices that are past due, or that reach a specific number of days since the due date.
- Check the invoice status in Xero before sending: if it is already paid or voided, skip.
- Pull the client details, invoice amount, and due date from the Xero record.
- Send the right email based on how many days overdue the invoice is.
- Log the reminder in a tracking spreadsheet or CRM so you have a record.
This means your reminder emails can be personalised with the client's name, the specific invoice amount, a direct payment link, and your business name, without anyone manually drafting them.
Common mistakes to avoid
Sending reminders to exempt clients. Some clients have different payment terms, or you might have already agreed to an extension. Your automation needs a way to tag exceptions so the sequence skips those invoices. A simple flag in your CRM or a custom field in Xero solves this.
Chasing the wrong person. If the invoice was addressed to a general email address but the person who approves payments is someone else, your reminders may never reach them. Confirm accounts payable contact details when you send the first invoice.
Going too aggressive too early. Day one overdue emails that sound threatening will damage relationships. Save the firm language for the second and third follow-up. The first message should always assume good faith.
Forgetting about partial payments. If a client pays part of an invoice, make sure your automation handles this correctly. A reminder that quotes the original full amount after a partial payment has been made will create confusion and frustration.
When to personalise versus automate
Automation handles the routine well. It sends reminders consistently, at the right intervals, every time, without your involvement. What it does not do is read the room.
If you know a particular client is going through a difficult period, or if you have already had a phone conversation about the invoice, you need a way to pause or override the sequence for that account. This is where a simple CRM flag or a manual exception list becomes important.
The goal is not to remove your judgment from the process entirely. It is to remove the administrative load so that when you do need to step in personally, it is because the situation genuinely requires it, not because you had to remember to send an email.
Getting started
If you are a small business running Xero, the fastest path is to turn on the built-in reminders as a baseline, then assess how much volume and complexity you have. If you are sending twenty or more invoices a month and chasing more than a handful of them, a more complete sequence connected through an automation platform will pay for itself quickly. We built a daily cashflow automation for a Xero-based trades business that cut their end-of-month admin from two days to four hours.
If you would like to understand what this could look like for your specific business, an Automation Assessment is a good starting point. It takes thirty minutes and gives you a clear picture of which automations make the most sense given your current setup.
Or if you already know this is something you want to build, join the waitlist and we can put it into the onboarding queue.
