Xero Invoice Reminders: Setup Guide + Best Schedules

Xero invoice reminders are one of those features that look simple on the surface.

Turn them on, pick a few days, and you are done.

But in practice, most businesses run into the same questions fast:

1. What is the best schedule to use?
2. Should I remind before the due date or only after?
3. Why didn’t a reminder send?
4. Why did a reminder send to the wrong person?
5. What do I do when the invoice problem is actually a PO or vendor setup problem, not a reminder problem?

This guide answers those questions in one place. You will get the setup steps, the Xero-specific limits that matter in real life, and the best reminder schedules to use depending on your payment terms and client type.

If you want the reminder layer to run outside your accounting app, with a client portal and reminders that stop once paid, you can also check Can You Pay That as the next step.

Key takeaways

1. Xero invoice reminders can send before or after the due date, and Xero supports up to five reminders in one organisation.
2. Xero reminders only work reliably when invoices are marked as sent, either by emailing from Xero or marking them sent manually.
3. Xero sends reminders once per day, based on your organisation’s time zone, so you should think in terms of dates and cadence, not minute-by-minute timing.
4. You can customize reminder content and include an online invoice link, PDF invoice link, and suppress reminders for invoices below a certain amount.
5. The best reminder schedule depends on the payment terms. Net 7 usually needs a tighter schedule than Net 30, and AP-heavy clients often need earlier clarity, not more aggression.

What Xero invoice reminders actually do

At the simplest level, Xero invoice reminders are automatic emails sent to customers when an invoice is approaching due date or is overdue. Xero’s support documentation explicitly frames reminders this way.

That sounds basic, but it matters because it means Xero can help with both:

1. preventive reminders before an invoice becomes late, and
2. collections reminders after the due date has passed.

The hidden requirement: invoices must be marked as sent

This is one of the biggest Xero gotchas.

Xero’s support materials make clear that emailing an invoice automatically marks it as sent, and you can also mark it as sent manually. That matters because invoice reminders depend on that sent status. If an invoice is not marked as sent, the reminder may not go out.

So if you create invoices in Xero but send them some other way, you still need a sent-status habit.

Who actually receives the reminders?

Xero says reminders go to the primary person on the contact and any additional people who have the relevant email inclusion setting enabled.

That means reminder quality starts with contact quality:

1. correct AP email
2. correct billing contact
3. any additional finance contact included intentionally

If you get that wrong, the reminder feature is “working,” but payment still gets delayed.

How to set up invoice reminders in Xero

Step 1: Go to the reminder settings

Xero’s support docs currently describe managing invoice reminders from Sales settings → Invoice settings → Invoice Reminders.

Depending on the Xero interface version and your region, you may also see invoice reminders surfaced from the Invoices area, but the settings path above is the clearest documented route.

Step 2: Turn reminders on

In the reminders area, enable the checkbox to email customers when an invoice is due or overdue. Xero’s setup doc describes this as the starting point for automatic reminders.

Step 3: Add or edit your reminders

Xero’s official guidance says you can create up to five reminders in your organisation.

This is the key Xero-specific design constraint, because it means your schedule should be intentional. You do not have unlimited steps, so each reminder has to earn its place.

Step 4: Configure when each reminder sends

Xero supports reminders before and after the due date.

This matters because a lot of businesses still treat reminders as “only after overdue,” but Xero’s own small-business guidance recommends a more proactive follow-up system with:

1. a pre-due reminder 2 to 3 days before payment deadlines, and
2. immediate overdue notices once a payment becomes late.

Step 5: Customize the email content

You can edit reminder emails in Xero, and Xero’s support snippets also confirm optional settings such as:

1. include a PDF invoice link
2. include a quick link to the online invoice and detail summary
3. do not send reminders below a certain outstanding amount threshold.

Those three options are more useful than they look:

1. Online invoice link reduces friction.
2. PDF link helps when invoices get forwarded internally.
3. Amount threshold prevents nagging over tiny balances.

Step 6: Set your due dates and payment terms properly

Reminder logic is only as good as the due dates behind it.

Xero has separate settings for default due dates and payment terms in invoice settings.

If your payment terms are messy, your reminder schedule will also be messy. Clean terms first, reminders second.

Step 7: Check whether reminders actually sent

Xero provides reminder status and history information, and its support content notes cases like:

1. invoice not sent
2. reminder not sent because invoice was not marked as sent.

In practice, that means you should periodically check reminder history for:

1. invoices you expected to be chased
2. invoices that are still marked overdue
3. invoices where reminder history shows nothing went out

The Xero-specific limits you should know before you choose a schedule

This is where most “setup guide” content stops too early.

1) Xero sends reminders once per day, not continuously

Xero’s official doc says reminders are sent every day between 4am and 8am, based on the organisation’s time zone.

That means:

1. a “due today” reminder is date-based, not sent at your preferred custom hour
2. if your AP-heavy client processes payments late afternoon, your reminder may still go out in the morning
3. you should think in calendar offsets, not exact times

2) Missed reminders are not backfilled

Xero also notes that if reminders were off and a reminder point was missed, turning reminders back on later will not necessarily generate the missed earlier reminder. Later reminders continue as normal.

This matters because it punishes sloppy setup. If you only activate reminders after an invoice is already overdue, you may not get the “full sequence” you thought you would.

3) Per-invoice exceptions exist, but Xero is not a full collections engine

Xero support snippets indicate you can turn reminders off for a specific invoice.

That is useful, but it is still not the same thing as having a full reminder-first workflow with:

1. per-client rules
2. richer escalation logic
3. portal-based payment UX
4. clear “stop when paid” flows outside your accounting UI

This is the line where some teams stay in Xero, and others add a dedicated follow-up layer.

Best reminder schedules to use in Xero

Here is the part most people actually need.

Xero gives you five reminder slots. So what should you do with them?

Schedule 1: Best default for most service businesses

This is the best general-purpose schedule if you sell services, work with freelancers or agencies, and want something calm but consistent:

1. 7 days before due
2. On due date
3. 3 days overdue
4. 7 days overdue
5. 14 days overdue

This lines up with your site’s proven default schedule and with the logic that early reminders prevent late payments while later reminders escalate gradually.

Use this if:

1. your terms are Net 14 or Net 30
2. you work with established clients
3. you want a predictable, low-drama cadence

For the deeper timing logic behind this, link internally to your best invoice reminder schedule.

Schedule 2: Best Xero setup for Net 7 terms

If your terms are already short, do not waste reminder slots on a long runway.

Use:

1. 3 days before due
2. On due date
3. 3 days overdue
4. 7 days overdue

Optional fifth reminder:

5. 14 days overdue only if you want a final documented touch.

Why this works:

1. Xero’s own payment-terms guide recommends pre-due reminders about 2 to 3 days before deadlines.
2. Net 7 means the billing cycle is already compressed, so a 7-days-before reminder would be too early.

Schedule 3: Best Xero setup for enterprise or AP-heavy clients

If your clients have Accounts Payable, approvals, PO requirements, or slower pay runs, pure “collections tone” often performs worse than “process clarity.”

Use:

1. 7 days before due
2. On due date
3. 7 days overdue
4. 14 days overdue
5. 21 days overdue

Why this schedule is different:

1. enterprise clients often need more room for internal routing
2. an earlier pre-due reminder gives time to fix AP blockers before the invoice is actually late
3. the later reminders should ask about payment date, PO, or vendor setup, not just “please pay”

If you keep hearing “we need a PO number” or “AP needs your vendor form,” that is not a reminder problem. It is a setup problem. Fix it with this vendor onboarding checklist.

Schedule 4: Best Xero setup for retainers

Retainers behave differently because they are recurring and emotionally closer to “rent” than “project invoice.”

Use:

1. 3 days before due
2. On due date
3. 3 days overdue
4. 7 days overdue
5. 14 days overdue, boundary-oriented

If you want the full calendar logic, your existing internal article on retainer invoicing is the better “deep dive.” For the actual date math, send readers to the invoice reminder schedule builder.

What to write in each reminder

Because you already have dedicated template content on the site, the best approach here is to give Xero-specific guidance for each slot, then link internally to the full template libraries.

Reminder 1: Before due date

Goal:

1. keep it light
2. make paying easy
3. catch AP routing issues before they become overdue

Recommended tone:

1. friendly
2. short
3. factual

Use wording modeled on your polite invoice reminder email template.

Reminder 2: On due date

Goal:

1. confirm this is due now
2. remove ambiguity
3. avoid sounding annoyed

Recommended structure:

1. invoice number
2. amount due
3. due today
4. online invoice or PDF link
5. payment link if available

Reminder 3: 3 days overdue

This is the most important overdue touch for many businesses.

Goal:

1. ask for a real status update
2. request a payment date
3. surface blockers like PO or vendor setup

Use your 3 days overdue reminder template here.

Reminders 4 and 5: Escalation

These should change from “reminder” to “process.”

What that means:

1. ask for the expected payment date
2. state any internal next step
3. if relevant, name the consequence calmly

If you need to move from reminder to boundary, use your pause work until paid email template for the final escalation step.

What reminders can’t solve

This section matters because a lot of users blame the reminder tool for problems it cannot fix.

Missing PO number

If the invoice needs a purchase order number to be approved, no reminder schedule can override that.

That is a procurement workflow issue, not a reminder timing issue.

Vendor onboarding is incomplete

If the client still needs:

1. tax form
2. bank details
3. vendor ID
4. remit-to confirmation

then the invoice may be technically sent but practically unpayable.

Again, fix the setup, not the tone.

Wrong AP contact

Xero can send reminders beautifully to the wrong person.

If reminders are landing in the wrong inbox, the system is working and your collections are still broken.

Invoice not marked as sent

This is the classic Xero gotcha. If the invoice is not marked as sent, reminders may not send at all.

When to keep Xero reminders vs when to add a dedicated follow-up layer

Xero is enough if…

1. your invoice volume is moderate
2. your clients are straightforward
3. you mainly need consistent nudges
4. you are happy with up to five reminder steps
5. you do not need a richer portal-style follow-up experience

Add a dedicated follow-up layer if…

1. you want reminders that feel separate from accounting admin
2. you want a simpler client payment experience
3. you need a more deliberate collections workflow
4. you want follow-up logic that feels designed for agencies/freelancers, not just accounting software defaults

This is the use case for Can You Pay That and why it complements Xero rather than replacing it.

Conclusion

Xero invoice reminders are genuinely useful, but they work best when you do three things well:

1. set them up correctly,
2. choose a schedule that matches your payment terms, and
3. fix process blockers that reminders cannot solve.

For most businesses, the best Xero schedule is not “turn on the defaults and hope.” It is a deliberate set of reminder offsets built around your real invoice cycle.

Use your internal support pages to keep this article tight:

1. the generic timing guide for the deeper why
2. the template pages for copy
3. the vendor onboarding page for AP blockers

And if you want the follow-up layer to run automatically with a cleaner client experience, check Can You Pay That.

FAQ

Does Xero send reminders before the due date?

Yes. Xero supports reminders for invoices whose due date is approaching, not just overdue invoices.

How many reminders can I set in Xero?

Xero supports up to five invoice reminders in an organisation.

Do invoices need to be marked as sent?

Yes, in practice this matters. Xero says emailing a transaction marks it as sent, and you can also mark it as sent manually so reminders will work correctly.

Can I add invoice PDF links to reminders?

Yes. Xero’s reminder settings support including PDF invoice links, and also an online invoice link/detail summary.

What is the best Xero reminder schedule for Net 7?

A strong default is 3 days before due, on due date, 3 days overdue, and 7 days overdue. That fits Xero’s feature set and lines up with Xero’s own recommendation for short pre-due reminders.

What if the client needs a PO or vendor setup?

Treat that as an AP/process issue, not a reminder issue. Fix it upstream with a billing profile and a vendor onboarding checklist.

Can I turn reminders off for one invoice?

Xero support content indicates you can turn reminders off for a specific invoice.

What should I do after the final Xero reminder?

At that point, stop relying on reminder tone alone. Move to a documented escalation step, such as requesting a payment date, resolving AP blockers, or using a pause-work boundary if your agreement allows it. Your existing pause work until paid email template is the right internal next step.
