Payment Reminder Email Templates

Three copy-ready emails for overdue invoices: a gentle reminder for the first week, a firm follow-up for 8 to 30 days late, and a final notice with a deadline. Pick the tone that matches how late the payment is, copy it, and replace the bracketed fields.

Best for: Freelancers and small businesses chasing an unpaid invoice who want proven wording rather than a blank email.

These are fixed templates, not generated text. Choose a tone, copy it, then replace every [BRACKETED] field before you send. Delete any sentence that does not apply to your agreement.

Use when: 1 to 7 days after the due date, or for a first reminder to a client who usually pays on time.

  • Attach the original invoice PDF again.
  • Replace [PAYMENT DETAILS] with your payment link or bank details.
  • Keep it short. No late fees, no deadlines.
Subject: Quick check-in on Invoice #[NUMBER]

Hi [CLIENT NAME],

I hope you're doing well! I wanted to follow up on Invoice #[NUMBER] for [AMOUNT], which was due on [DUE DATE].

I understand things can get busy, so this is just a friendly reminder. If the payment is already on its way, please disregard this message.

You can pay via [PAYMENT DETAILS]. I've attached the invoice again for convenience.

If you have any questions about the invoice or need to discuss the payment timeline, I'm happy to chat.

Best regards,
[YOUR NAME]

Which template should you send, and when?

Match the tone to the number of days overdue and to what has already happened. A gentle email at day 3 and a final notice at day 45 are both professional; sending them the other way round is not. The schedule below is a practical default, not a rule. Shorten it for small one-off jobs and lengthen it for a large client with a monthly payment run.

What every payment reminder email needs

A reminder works when the client can pay from the email without searching for anything. Check these six items before you hit send:

  • Invoice number in the subject line so the client and their accounts team can search for it.
  • The exact amount still owed. If the client paid part of it, quote the remaining balance, not the original total.
  • The original due date and, from the firm stage on, how many days overdue it is.
  • One clear way to pay: a payment link, or bank details with the invoice number as the reference.
  • A specific ask: "Can you confirm when this will be paid?" gets more replies than "Please pay at your earliest convenience" alone.
  • The invoice attached again, at least for the first two reminders.

If the invoice itself is missing details (a PO number, the client's legal name, a tax ID they need), fix and reissue it first. A reminder for an invoice the client cannot process will not get paid. Our guide to writing an invoice lists the standard fields.

Worked example: filling in the gentle and final templates

Example scenario (illustrative): a designer sent Invoice #1042 for $2,400 on net 30 terms, due 1 October 2026. Their contract says overdue balances accrue 1.5% per month.

Day 4: gentle reminder

[NUMBER] becomes 1042, [AMOUNT] becomes $2,400, [DUE DATE] becomes 1 October 2026, and [PAYMENT DETAILS] becomes the payment link or the bank account with "1042" as the reference. Nothing about fees: at day 4 the most likely story is that the invoice is sitting in someone's inbox.

Day 45: final notice with the agreed late fee

By 15 November the invoice is 45 days overdue. The contract rate of 1.5% per month is 18% a year. As simple interest: $2,400 × 18% × 45 ÷ 365 = $53.26, so [TOTAL WITH FEES] is $2,453.26. [DEADLINE DATE] is 22 November, 7 days after the notice. If your contract instead charges a flat 1.5% for each month or part-month overdue, the fee is $36 per month, so check the wording before you calculate. The late fee calculator does the simple-interest version for you.

Can you charge late fees or interest in a reminder?

Only where you already have the right to. The final notice template mentions a late fee because many service contracts include one; delete that paragraph if yours does not. Two common situations:

This is general information, not legal advice. Rules differ for consumer customers and by country; check the official guidance where you and your client are, or ask an adviser. Last reviewed October 2026.

Sending reminders automatically instead

These templates are for one-off chasing from your own inbox. If you invoice in InvoiceQuickly, the Pro plan ($9/month) can send scheduled reminder emails before and after the due date and stops once the invoice is marked paid or cancelled. The Free plan does not send emails. Reminder settings apply to the whole account, so clients on special terms still need a personal email like the ones above. Read how to set up an automatic reminder schedule for the trade-offs.

When this isn't the right fit

The client may already have paid. Check your bank, Stripe or PayPal account and any partial payments before sending another reminder; chasing a paid invoice costs more goodwill than it recovers.

The final notice deadline has passed with no reply. Another email will not help. Call, send a formal letter of demand, or start the small-claims or collection process that applies to you. Our late payment guide covers those steps.

The client is disputing the work, not the timing. A reminder will not settle a quality disagreement. Talk it through first, then reissue or credit the invoice if something changes.

Frequently asked questions

When should I send the first payment reminder?

Within the first week after the due date. Use the gentle template, assume it was missed rather than refused, and attach the invoice again. If you want a heads-up before the due date, a one-line note 3 to 5 days ahead works, but it is not one of the three templates here.

How many payment reminders should I send before escalating?

Usually three emails: gentle, firm and final notice. If the final notice deadline passes with no payment and no reply, more emails rarely change anything. Switch to a phone call, a formal letter of demand, or the small-claims or collection route that applies where you and the client are.

Can I add a late fee to a payment reminder?

Only if your contract or invoice terms already include one, or a law gives you the right. In the UK, businesses can claim statutory interest of 8% plus the Bank of England base rate on late business-to-business payments, plus fixed recovery costs of £40, £70 or £100 depending on the debt size. US rules vary by state. Do not invent a fee in a reminder that was never agreed.

Should I attach the invoice PDF to every reminder?

Attach it to the gentle and firm reminders so the client cannot say they lost it. By the final notice the problem is priority, not access, so keep the invoice attached but focus the email on the amount, the deadline and what happens next.

Does this tool write or send the reminder for me?

No. It shows three fixed templates with bracketed placeholders. You copy one, fill in the details yourself and send it from your own email. Nothing you type is generated, stored or sent by the page.

What subject line should a payment reminder use?

Put the invoice number in the subject so the client can search for it, and make the status clear: "Quick check-in on Invoice #1042" for a first reminder, "Payment overdue: Invoice #1042" when firm, and "Final notice: Overdue Invoice #1042" at the end.
