Payment Reminder Email Templates (Before and After the Due Date)

Payment Reminder Email for Overdue Invoices

A payment reminder email is a message sent to a customer about an invoice that’s due soon or hasn’t been paid on time. It gives them the invoice details, confirms the amount owed, and makes it easy to complete the payment.

Not every reminder needs to sound urgent. A quick email before the due date can be enough to prevent an invoice from being overlooked. But if payment is still outstanding weeks later, you’ll need to be more direct.

Below, you’ll find ready-to-use payment reminder emails and text messages for six stages, from three days before payment is due to 30 days overdue. There are also templates for payment plans, resending invoices, and confirming a payment.

When to send a payment reminder

You don’t need to wait until an invoice is overdue to send a reminder. Contacting customers a few days before payment is due gives them time to check the invoice and arrange payment.

If the deadline passes, follow up in stages rather than sending the same message repeatedly.

Formal and serious

This is a suggested schedule, not a set of legal deadlines. You might send fewer reminders to a long-standing customer who usually pays on time, or follow up sooner on a large invoice that’s affecting your cash flow.

Whatever schedule you choose, check the invoice status before sending another message. A customer may have already paid, even if the payment hasn’t appeared in your records yet.

Payment reminder email templates by stage

These six templates cover the most common points in the payment process. Copy the email or text message you need, replace the details in brackets, and adjust the wording to suit your relationship with the customer.

Each includes a payment link so the customer can settle the invoice without searching through previous emails.

1. Payment reminder: 3 days before the due date

6. Payment reminder: 30 days overdue

At 30 days overdue, the message should clearly establish what’s outstanding and ask the customer to take action. You can be firm without making threats or referring to legal consequences that haven’t been established.

Subject: Outstanding balance: Invoice [Invoice Number] is 30 days overdue

Dear [Client Name],

We’re contacting you regarding invoice [Invoice Number] for [Amount Due], originally due on [Due Date].

The balance remains outstanding 30 days after the payment deadline.

For invoices that may ultimately remain unpaid, see our guide to uncollectible accounts.

Additional payment reminder templates

Not every payment issue follows the same timeline. Sometimes a customer needs more time, can’t find the invoice, or has already paid.

These three messages cover those situations without restarting the standard reminder sequence.

7. Payment plan request

Use this when a customer has explained that they can’t pay the full balance at once, or you want to offer an opportunity to discuss an alternative arrangement.

Subject: Let’s discuss payment for invoice [Invoice Number]

Hi [Client Name],

I’m following up about the outstanding balance of [Amount Due] on invoice [Invoice Number].

If paying the full amount right now isn’t possible, please get in touch. We can discuss whether a payment arrangement would work for both sides.

Any agreed payment dates and amounts will be confirmed in writing, so we’re both clear on the next steps.

You can also review the outstanding invoice here: [Payment Link]

Thanks,
[Business Name]

8. Resending an invoice

If the customer can’t find the original invoice, don’t turn it into another overdue warning. Simply resend the information they need.

Subject: Your copy of invoice [Invoice Number]

Hi [Client Name],

Of course, here’s another copy of invoice [Invoice Number] for [Amount Due], due on [Due Date].

You can view the invoice and make payment here: [Payment Link]

Let us know if you have any trouble opening it or need anything else.

Thanks,
[Business Name]

9. Payment received: Thank-you message

Once payment has been confirmed, a short acknowledgment closes the loop and reassures the customer that their records are up to date.

Subject: Payment received for invoice [Invoice Number]

Hi [Client Name],

Thanks for your payment of [Amount Paid] toward invoice [Invoice Number].

We’ve received it and updated our records accordingly.

We appreciate your business and look forward to working with you again.

Best,
[Business Name]

What not to write in a payment reminder

Chasing an unpaid invoice can be frustrating, especially when you’ve already followed up several times. But the wording matters. An aggressive message can damage a customer relationship and make it harder to resolve a straightforward billing problem.

Here’s what to avoid and what to say instead.

Avoid

Instead, write

“Pay immediately or we’ll take legal action.”

“Please contact us to confirm when payment can be made or discuss any issue with the invoice.”

“You’ve deliberately ignored our invoices.”

“We haven’t received a response to our previous reminders. Could you provide an update?”

“You legally have 24 hours to pay.”

“Please let us know your expected payment date.”

“We’ve added a late fee because you didn’t pay.”

“Please review the outstanding balance and contact us if you have any questions about the agreed payment terms.”

“This is your last chance.”

“We’d appreciate a response so we can agree on the next steps.”

A few things are worth checking before you press send.

Don’t assume the customer is refusing to pay. An invoice might have gone to the wrong email address, be waiting for approval, or have been paid without the transaction appearing in your records.

Don’t invent legal deadlines or consequences. If you haven’t established the basis for a particular demand, don’t include it to make the message sound more urgent.

Don’t add unsupported late fees. Any additional charges should be consistent with the agreement and applicable law.

The aim is to get a clear response and resolve the outstanding payment, not make the email sound as severe as possible.

How to automate payment reminders with Invoice Fly

If you’re managing several jobs or customers at once, remembering which invoice needs another reminder can become a job in itself.

Invoice Fly supports automatic payment reminders, allowing businesses to schedule follow-ups around invoice due dates rather than writing every email manually.

You can use Invoice Fly to:

  • Set up automatic reminders: Arrange for payment reminders to be sent based on invoice due dates.
  • Choose reminder timing: Use the reminder scheduling options available in your account to plan when customers receive follow-ups.
  • Send reminders to customers: Keep payment communication consistent without having to draft every message from scratch.
  • Check invoice statuses: See which invoices have been sent, viewed, paid, or become overdue before deciding whether further follow-up is needed.

Invoice Fly also offers payment status notifications, including alerts when an invoice is viewed, paid, or becomes overdue. These can help you keep track of customer activity and respond when a payment needs attention.

Automatic reminders are especially useful for contractors managing multiple jobs, freelancers working with several clients, and small businesses without a dedicated accounts receivable team.

You can explore Invoice Fly’s automatic payment reminders to spend less time checking outstanding invoices and more time on your actual work.

Keep payment follow-ups clear and consistent

You don’t need a different strategy every time a customer misses a payment. Start with a friendly reminder, make each follow-up a little more direct, and always give the customer the details they need to pay or explain a delay.

If you’re regularly dealing with late client payments or trying to manage an outstanding invoice, having a consistent process makes it easier to stay on top of what you’re owed.

And if you’re still setting up your billing process, our guide on how to send an invoice covers the basics.

Payment Reminder Email FAQs

Your payment reminders should be clear and direct. Be sure to include:

  • Invoice number and due date
  • Outstanding balance
  • Accepted payment methods and payment link
  • Late fee policies (if applicable)
  • Contact information in case the client has any questions

If your payment reminder email isn’t effective, consider the following:

  • The subject line may not be clear or urgent enough
  • The email might be too aggressive or too vague
  • The client may not know how to pay — always include clear payment instructions
  • The email lacks follow-up — send multiple reminders at different stages
  • The recipient’s contact details may be outdated or incorrect

The time to send a reminder depends on the invoice’s due date:

  • A few days before the due date – Friendly reminder
  • On the due date – Confirmation the payment is now due
  • One week overdue – A firm but polite nudge
  • Two weeks overdue – Stronger reminder warning about late fees
  • One month overdue – Legal action warning or final notice

If a client ignores reminders and still has unpaid invoices, follow these steps:

  • Send a final demand letter with a legal action warning
  • Offer a payment plan as a last attempt to settle
  • Engage a collections agency for persistent non-payers
  • Seek legal action if necessary, ensuring all documentation is in order

Managing accounts receivable efficiently helps prevent cash flow problems. Use automation tools like Invoice Fly’s Reporting Software to:

  • Track outstanding invoices in real time
  • Send automated reminders at the right stages
  • Keep a detailed history of payments and client interactions
  • Ensure follow-ups happen without manual effort

You can send a friendly reminder a few days before the due date or shortly after payment becomes overdue. The timing depends on your payment terms and customer relationship.

There's no fixed number. Start with a friendly reminder and become more direct if payment remains outstanding. This is part of the dunning process.

Yes, if your agreement and applicable law allow it. Some jurisdictions limit late fees, so check the rules before adding charges. Learn more about invoice late fees.
