Payment reminder email templates, from a nudge to a final notice.

A payment reminder should answer three questions: which invoice, how much is still due, and what happens next. Below are six email templates: five ways to follow up, from a friendly heads-up to a final notice, plus a thank-you after payment.

Six payment reminder email templates

Before sending, check the invoice and payment records. Use the remaining balance after any partial payment, include the currency, and test the invoice link. These are emails for you to adapt; the suggested days are a starting schedule, not legal deadlines.

1. Polite payment reminder before the due date

When to use it: About three days before payment is due. Keep it helpful; the client has not missed a deadline.

Subject: Invoice [number] is due on [due date]

Hi [name],

A quick heads-up that invoice [number] for [project or service] has a balance of [amount and currency] due on [due date].

You can view the invoice and payment details here: [invoice link]. If you need a purchase order added or the invoice sent to someone else, please let me know.

Thanks,
[your name]

2. Invoice payment reminder email on the due date

When to use it: On the agreed payment date. State what is due without calling it overdue.

Subject: Invoice [number]: [amount and currency] due today

Hi [name],

Invoice [number] for [project or service] is due today, [due date]. The remaining balance is [amount and currency].

Here are the invoice and payment details: [invoice link]. If you have already sent payment, thank you. Please share the payment date or reference so I can check it against our records.

Best,
[your name]

3. Overdue invoice email: seven days late

When to use it: Payment is a week late and you have not agreed a different date. Ask for a specific update.

Subject: Payment update requested: invoice [number], seven days overdue

Hi [name],

I'm following up on invoice [number] for [project or service]. The remaining [amount and currency] was due on [due date], and I have not received it.

Please arrange payment here: [invoice link], or reply with the date I can expect it. If anything on the invoice needs correcting, let me know so we can resolve it.

Thank you,
[your name]

4. Second reminder for an outstanding payment: fourteen days late

When to use it: Your first overdue reminder has not resolved the balance. Give the client a clear date to respond.

Subject: Second reminder: invoice [number], [amount and currency] outstanding

Hi [name],

Following my email on [previous reminder date], invoice [number] still has [amount and currency] outstanding. It was due on [due date] and is now fourteen days overdue.

Please pay at [invoice link] or confirm a payment date by [reply-by date]. If payment is waiting for approval, please put me in touch with the person handling it.

If there is a dispute or a problem paying, please tell me so we can discuss the next step.

Regards,
[your name]

5. Final payment notice: thirty days late

When to use it: Earlier follow-ups and direct contact have not resolved the invoice. Choose a next step you intend to take and that your agreement and local rules allow.

Subject: Final payment reminder: invoice [number], reply by [date]

Hi [name],

Invoice [number], due on [due date], is now thirty days overdue. The remaining balance is [amount and currency]. My previous reminders were sent on [dates].

Please pay by [payment deadline] using [invoice link], or contact me by that date to resolve any issue.

If I do not receive payment or hear from you, my next step will be [specific action permitted by our agreement and applicable rules]. I would prefer to resolve this directly with you.

Regards,
[your name]

This email does not replace a formal demand or any notice required before legal action. If the client remains silent, use our step-by-step guide to an unpaid client invoice to assess your options.

6. Payment received: a short thank-you email

When to use it: Once you have confirmed full payment. For a partial payment, acknowledge what arrived and state the balance that remains.

Subject: Payment received for invoice [number], thank you

Hi [name],

Thank you. I've received [amount and currency] for invoice [number], which is now paid in full.

I appreciate your business and look forward to working together again.

Best,
[your name]

Payment reminder subject lines

Put the invoice number and what you need in the subject, so the email is easy to find and to forward to whoever pays. Each template above has one; these say the same thing another way:

• Before the due date: Quick reminder: invoice [number] due [due date]
• Due today: Invoice [number] is due today
• Seven days late: Invoice [number] is now overdue
• Fourteen days late: Following up: invoice [number] is still open
• Final notice: Action needed by [date]: invoice [number]
• Paid: Thank you: invoice [number] is paid

When to send a reminder, and when to call

Start with a heads-up before the due date, a reminder on the day, then follow-ups at seven and fourteen days late. Consider a final notice at thirty days only after checking the circumstances. Call sooner if the invoice is large, the client has missed a promise, or a billing problem needs a conversation. Do not keep sending the same sequence after a dispute or a request for help paying.

The UK Small Business Commissioner's unpaid-invoice guidance recommends checking the terms and invoice, sending a polite reminder, then contacting the client directly. It does not prescribe the intervals above. If you agree a revised payment date, confirm it in writing and follow up against that agreement.

Make the next invoice easier to follow up: agree the payment terms and due date before work begins. Our free freelance invoice template helps you set out the work, amount and deadline clearly.

Rather not keep the dates yourself? On Pro and Team, BillGrid sends client reminders on your schedule and stops when the invoice is paid in full.

When the situation isn't simple

The client paid part of it

Thank them for what arrived and state what is left, with the original due date. Try: "Thank you for the [amount received]. That leaves [amount and currency] on invoice [number], which was due on [due date]."

"We never got the invoice"

Resend it straight away, without comment, and ask who should receive invoices from now on. Try: "Here it is again: [invoice link]. Who should I send future invoices to?"

It's waiting on approval or a purchase order

Larger clients pay through accounts payable, and the person you work with may not control the timing. Ask for the purchase order number and the name of whoever approves payment, then follow up with them directly.

The client disputes the invoice

Pause the reminders and answer the specific point. Ask them to pay the part that is not in question while you resolve the rest, and confirm what you agree in writing.

They can't pay it all at once

Offer a short written plan with amounts and dates, and thank them as each payment arrives. Try: "I can split the [amount and currency] into [number of payments] payments of [payment amount], due on [payment dates]. Please confirm and I'll send the schedule."

Should you pause the work?

Only if your agreement allows it. Say plainly and calmly that work pauses until the balance is paid and resumes as soon as it is, rather than going quiet.

Before a final notice: what the law adds

This is general information, not legal advice; your contract comes first, and the rules depend on where you and your client are.

• UK: between businesses, the Late Payment of Commercial Debts (Interest) Act 1998 lets you claim interest at 8% above the Bank of England base rate, plus fixed compensation of £40, £70 or £100 per invoice depending on its size, unless your contract sets its own rate. The late fee calculator works it out. If your client is an individual or sole trader, a court claim must first follow the Pre-Action Protocol for Debt Claims: a letter of claim and 30 days to reply.
• EU: the Late Payment Directive sets interest of at least 8 points above the central bank's reference rate and €40 compensation when a business pays late. A 2023 proposal to tighten it has not been adopted.
• US: what you can charge comes from your contract and state law. New York, Illinois and California protect freelancers directly: work over $800, $500 and $250 needs a written contract, payment is due within 30 days when it names no date, and a client who pays late can owe up to double.

Whatever you send, never sign as a collection agency or legal department you don't have. In the US, a creditor collecting a consumer debt under a name that suggests someone else is collecting is treated as a debt collector under the Fair Debt Collection Practices Act. Don't threaten a step you won't take, and don't send demands so often or in such a way that they would alarm or humiliate; in the UK that is an offense under section 40 of the Administration of Justice Act 1970. The freelance payment laws guide covers each US law in force.

Common payment reminder questions

How do I ask for payment politely without sounding apologetic?

State the invoice number, remaining balance and due date, then ask for payment or a confirmed date. You do not need to apologize for following up on agreed work. Leave room for a genuine billing error; a clear question is more useful than an accusation.

Can I use the same wording in a payment reminder letter?

For an ordinary reminder, adapt the relevant email above: add the date, both parties' names and addresses, the invoice reference, balance and payment instructions. Our payment reminder letter templates have all of that, from a first reminder to a final demand, ready to print or open in Word. Keep a copy. A formal demand letter may need different wording, a particular delivery method or a prescribed response period; check the rules before treating a reminder as legal notice.

How many payment reminders should I send?

Usually three to five over about a month: a heads-up, one on the due date, then two or three follow-ups before a final notice. After that, a call or a formal step does more than another email.

Should I add a late fee to the reminder?

Only a fee or interest you are entitled to charge, shown separately from the balance. What the law adds covers the UK, EU and US rules, and the late fee calculator does the arithmetic.

What the research says about reminders

In the QuickBooks 2026 Small Business Late Payments Report, 59% of surveyed US small businesses reported invoices overdue by at least thirty days. That establishes the scale of the problem, not the reason any particular client has not paid. Across Xero's small-business customers, invoices were paid an average of 7.8 days late in the US and 8.0 in the UK at the end of 2025.

In an Australian field experiment, a reminder letter increased business taxpayers' likelihood of paying overdue debt by about 25 percentage points compared with no letter. Earlier reminders brought payment forward without changing the share that eventually paid (Gillitzer and Sinning, Journal of Economic Behavior & Organization, 2020). Tax collection differs from client invoicing. The study supports sending a reminder; it does not promise results for these templates.

What the reminder says can add to that. In UK trials with more than 200,000 taxpayers, reminder letters that added financial information raised payment rates significantly (Hallsworth, List, Metcalfe and Vlaev, Journal of Public Economics, 2017). Who it comes from matters too: in a field trial of loan reminders, text messages reliably improved repayment only when they named the loan officer, and only for borrowers who already knew that officer (Karlan, Morten and Zinman, NBER). Sign as yourself, not "Accounts." We found no credible study of subject lines or the best time of day to send; advice that names one is guesswork.

Schedule the follow-up in BillGrid

On Pro and Team, turn on automatic client reminders in Settings > Payment terms. Standard emails the client three days before, on the due date, then seven and fourteen days late, with a heads-up to you at day three. Firm adds client reminders at three, twenty-one and thirty days late and moves your heads-up to day seven. You can customize steps up to thirty days before or after the due date, addressed to the client or to you. On Free, schedule reminders to yourself and follow up with the client by hand.

Client reminders apply to sent invoices with email contacts, including invoices marked as sent. They stop when the balance is paid in full. You can pause an invoice's reminders or skip the next one. Sending a manual reminder from BillGrid also holds back automatic client reminders due in the next three days. The payment terms and reminders guide explains the settings and exclusions.

Each scheduled client reminder has its own subject and message, written for the day it goes out. A new account starts with the first five emails above on the days they were written for, the final notice without a next step until you add yours, and BillGrid's own wording for the days between. Change any step in Settings > Payment terms, or paste a template from this page: its [brackets] become fields BillGrid fills in, and any bracket it can't fill has to be replaced before you apply it. Rather send one message at every step? Choose the same wording for every reminder, saved under Payment reminder in Email defaults. If you enable late fees and their warnings, reminders also show when a fee is due and how much it will be.
