Quick Answer: Xero includes an invoice reminder feature with up to five stages and basic pre-due-date support, but it requires manual triggering, offers no per-client customisation, and provides no analytics. To get fully automated reminders, unlimited stages, per-client control, and payment tracking, you need a dedicated add-on like Wren that connects to Xero via its official API.
Xero is one of the most popular accounting platforms in Australia, and for good reason. It handles invoicing, bank reconciliation, and reporting with a clean interface that actually makes sense. But Xero invoice reminders have gaps that cost you time and money. According to the Australian Small Business and Family Enterprise Ombudsman (ASBFEO), late payments remain one of the top three issues facing Australian small businesses.
As of February 2026, if you have ever tried to set up invoice reminders in Xero, you know the frustration. The customisation is limited, and the scheduling requires manual effort every time. This guide covers exactly what Xero offers, where it falls short, and how to build a reminder system that actually gets invoices paid on time.
What Xero offers out of the box
Xero does have an invoice reminder feature. You will find it under Settings, then Invoice Settings, then the Reminders tab. According to Xero’s support documentation, you can enable up to five reminder stages, each with its own timing and email template.
When you first enable reminders, Xero creates three default stages at 7, 14, and 21 days overdue. You can add up to two more beyond the defaults for a total of five. Each stage lets you choose timing relative to the due date, including a “due in” option for pre-due-date reminders. You can customise the subject line and body text, and Xero will automatically insert the invoice number, amount, and due date using template variables. You can also choose whether to send reminders for all overdue invoices or just selected ones.
On the surface, this sounds workable. Five stages with customisable text and pre-due options should cover most situations. But once you start using it in a real business, the limitations appear quickly.
Key Takeaway: Xero’s native reminder feature supports up to five stages with customisable text and basic pre-due-date options, but it still requires you to manually review and click Send each time.
The limitations of Xero’s built-in reminders
While Xero has improved its Xero invoice reminders feature over time, several significant gaps remain for businesses that need reliable, hands-off invoice chasing.
Manual triggering. This is the biggest limitation. Xero does not send reminders automatically on a schedule. You need to go into the Invoice Reminders section, review the list, and click Send. If you forget, or if you are away for a few days, the reminders do not go out. This defeats much of the purpose of having a reminder system. According to Xero users on the product ideas forum, automatic sending is the most requested improvement.
No per-client customisation. Every client gets the same reminder sequence. You cannot send a gentler tone to your best client and a firmer tone to a repeat offender. In reality, different clients need different approaches, and a one-size-fits-all reminder feels impersonal or inappropriate.
Limited to five stages. Five reminders work for clients who simply forgot. But for chronic late payers, you may need a longer escalation sequence with six, seven, or more touchpoints before escalating to a formal demand or debt collection. Xero caps you at five.
Basic pre-due-date reminders. While Xero does support “due in X days” reminders, the implementation is basic. You get the same template options as overdue reminders, with no special handling for pre-due messaging. There is no ability to create a different tone or style for the pre-due stage compared to overdue stages.
No tracking or analytics. Xero does not tell you which reminders were opened, which were effective, or which clients consistently pay late. Without this data, you are flying blind, unable to refine your process or identify problem accounts.
No SMS reminders. Some clients respond better to text messages than emails, especially for smaller invoices. Xero only supports email reminders.
No time-of-day control. You cannot choose when reminders are sent during the day. This means you have no control over whether your reminder arrives at 9 AM on a Monday (ideal) or 11 PM on a Friday (easily ignored).
Key Takeaway: Xero’s biggest gaps are manual triggering, no per-client customisation, no analytics, no SMS support, and no time-of-day control. These limitations mean most businesses end up chasing invoices manually despite having reminders set up.
Xero reminders vs Wren: a direct comparison
If you are comparing Xero invoice reminders to dedicated tools, here is a side-by-side look at what each option provides.
| Feature | Xero Built-In | Wren |
|---|---|---|
| Pre-due-date reminders | Basic (same templates as overdue) | Yes (dedicated pre-due templates) |
| Reminder stages | 5 maximum | Unlimited |
| Per-client customisation | No (one sequence for all) | Yes (per-client tone and schedule) |
| Automatic sending | No (manual review and click) | Yes (fully automated, 24/7) |
| SMS reminders | No | Yes (email and SMS) |
| Open/read tracking | No | Yes |
| Payment analytics | No | Yes (average days to pay, overdue trends) |
| Late fee notices | No | Coming soon (automatic calculation and notice) |
| Time-of-day control | No | Yes (send at optimal times) |
| Stops when paid | Yes (after manual review) | Yes (instant, automatic) |
| API availability | No (reminders not available via API) | Full API integration (read-only) |
| Setup time | 5 to 10 minutes | Under 5 minutes |
The core difference is that Xero was built to send invoices, not to chase them. Its reminder feature is a secondary addition, not a core function. Wren was designed specifically to handle the entire accounts receivable follow-up process.
Key Takeaway: Xero’s reminder feature covers the basics, but a dedicated tool like Wren addresses the key limitations: fully automatic sending, unlimited stages, per-client customisation, SMS support, and actionable analytics.

How to upgrade Xero with Wren
Key Takeaway: Wren connects directly to Xero to automate the entire reminder lifecycle, providing the customisation and analytics that Xero’s native reminders lack.
Wren was built specifically to fill these gaps. It connects directly to your Xero account using Xero’s official API, reads your invoice data in real time, and manages the entire reminder lifecycle for you. No manual clicking, no forgetting, no one-size-fits-all emails.
With Wren, you get pre-due-date reminders with dedicated templates, unlimited escalation stages, per-client customisation, and full analytics on every reminder sent. It runs in the background, 24/7, and you only get involved when you want to. Your Xero data stays in Xero. Wren reads it, but never modifies your invoices or accounting records.
The result is fewer overdue invoices, faster payments, and none of the awkward manual chasing.
Setting up automated reminders
Getting started takes less than five minutes. Here is how to set up a complete reminder workflow that runs on autopilot.
Step 1: Connect your Xero account. Sign in to Wren and authorise the Xero connection. This is a standard OAuth flow, the same process you use to connect any Xero add-on. Your credentials are never stored.
Step 2: Choose your reminder schedule. Set up when reminders should go out. A recommended starting sequence is: 3 days before due, on the due date, 7 days overdue, 14 days overdue, and 21 days overdue. You can adjust these intervals at any time.
Step 3: Customise your message tone. Each stage can have its own email template. Start friendly and gradually increase formality. Wren includes professionally written templates out of the box, or you can write your own. Need inspiration? See our overdue invoice email templates for ready-to-use scripts.
Step 4: Set exclusions. Choose which clients or invoices to exclude from automated reminders. Some businesses prefer to handle their largest clients manually while automating everything else.
Step 5: Turn it on. Once your schedule and templates are set, activate the automation. Wren will start monitoring your Xero invoices immediately and send reminders according to your rules.
That is it. No complicated setup, no code, no ongoing maintenance. The system monitors your invoices, sends the right message at the right time, and stops automatically when the invoice is paid.
Key Takeaway: Setup takes under five minutes. Connect Xero, set your reminder schedule, customise your templates, choose exclusions, and turn it on. The system handles everything from that point forward.
Best practices for Xero reminder add-ons
Key Takeaway: The best Xero reminder add-ons use direct API integration to automate critical features like pre-due reminders, per-client customisation, and stopping reminders the moment an invoice is paid.
If you are evaluating tools to extend your Xero invoice reminders, here are the features and practices that matter most.
Direct Xero integration via API. The tool should connect through Xero’s official API, not through screen scraping or manual data exports. This ensures real-time data accuracy and means the tool automatically knows when an invoice is paid.
Pre-due-date reminders with dedicated templates. The ability to send reminders before the due date is the single most effective feature for preventing late payments. As of 2026, pre-due reminders consistently reduce late payments because they catch forgetful clients before the invoice becomes overdue. The tool should support different templates for pre-due and overdue stages, since the messaging is fundamentally different.
Per-client control. You need the ability to customise the reminder tone, timing, and number of stages for different clients or client groups. A first-time late payer and a chronic offender should not receive the same sequence.
Analytics and reporting. A good tool tracks open rates, response rates, average days to payment, and identifies your worst offenders. This data helps you refine your approach and make better decisions about client relationships.
Automatic stop on payment. The tool must automatically stop sending reminders the moment a payment is received. Nothing undermines your professionalism faster than chasing a paid invoice.
Late fee calculation. If you charge late payment fees, the tool should calculate the fee automatically and include it in the reminder. This saves manual calculation and ensures accuracy. Under the Australian Consumer Law, late fees must be a genuine pre-estimate of costs, so accurate, automated calculation matters.
The bottom line
Key Takeaway: The best Xero reminder add-ons use direct API integration to automate critical features like pre-due reminders, per-client customisation, and stopping reminders the moment an invoice is paid.
If you are using Xero and you are still chasing invoices manually, you are doing more work than you need to. Xero is a great accounting tool, but it was not built to be a collections platform. Its reminder feature has improved with five stages and basic pre-due support, but the manual triggering and lack of per-client control mean most businesses still end up doing the chasing themselves.
Let Xero do the accounting, and let Wren handle the chasing. The difference between spending hours per month on manual follow-ups and having a fully automated system is a five-minute setup. For broader strategies on how to improve cash flow beyond just reminders, see our complete guide. For most Australian small businesses, the automation pays for itself quickly when you compare the subscription cost to the hours saved on manual follow-ups.

Frequently Asked Questions
Key Takeaway: The best Xero reminder add-ons use direct API integration to automate critical features like pre-due reminders, per-client customisation, and stopping reminders the moment an invoice is paid.
Can I use Xero’s built-in reminders and Wren at the same time?
Yes, but it is not recommended. Running both systems simultaneously means your clients could receive duplicate reminders for the same invoice, which looks unprofessional. The best approach is to disable Xero’s built-in reminders once Wren is active. Wren provides everything Xero’s reminders do and more, so there is no benefit to running both.
Does Wren modify my Xero data?
No. Wren uses read-only access to your Xero account. It reads invoice data (amounts, due dates, payment status) to trigger reminders, but it never creates, modifies, or deletes any records in Xero. Your accounting data remains untouched.
What Xero plans does Wren work with?
Wren works with all Xero plans that support the invoicing API, which includes Starter, Standard, and Premium. If your Xero plan allows you to create and send invoices, Wren can connect to it.
How quickly does Wren detect a payment in Xero?
Wren syncs with Xero multiple times per day. When a payment is recorded in Xero, Wren typically detects it within a few hours and automatically stops any pending reminders for that invoice. You will never chase a paid invoice.
Can I send reminders in different languages for international clients?
Yes. Wren allows you to create custom email templates for different clients or client groups. If you have international clients who prefer communication in a language other than English, you can create separate templates for those clients and assign them accordingly.
What happens to reminders if my Xero subscription lapses?
If your Xero connection is interrupted for any reason, Wren pauses all reminders and notifies you immediately. No reminders will be sent with outdated or inaccurate data. Once the Xero connection is restored, the system resumes automatically.
