Payment Reminder Email Templates

Five copy-paste templates, one for each register — simple, friendly, professional, formal and firm. Swap the bracketed fields for your invoice details and send.

Simple — the shortest version that works

Three lines. Use it when you know the client and just need the invoice back on their desk.

Subject

Invoice [Invoice number] — [Amount] due [Due date]

Body

Hi [Client name],

Invoice [Invoice number] for [Amount] is due on [Due date]. Payment link: [Payment link]

Thanks,
[Your name]

Friendly — 3 days before the due date

Proactive and warm. Frames the message as a courtesy rather than a chase.

Subject

Quick heads-up — invoice [Invoice number] due [Due date]

Body

Hi [Client name],

Just a quick note that invoice [Invoice number] for [Amount] is due on [Due date].

If payment is already scheduled, please ignore this — I would rather send a redundant reminder than have it slip past you. Any questions about the invoice, just reply.

Thanks again for your business,
[Your name]
[Business name]

Professional — around 7 days overdue

Neutral and factual. The default once an invoice is genuinely late.

Subject

Invoice [Invoice number] — now past due

Body

Hi [Client name],

I am following up on invoice [Invoice number] for [Amount], which was due on [Due date] and is now past due.

Could you confirm when payment will be sent? If something is holding it up on your end — a missing PO, a query on the invoice, an approval step — let me know and I will help sort it.

Payment link: [Payment link]

Thanks,
[Your name]
[Business name]

Formal — for corporate accounts payable

Full sentences, no contractions, proper title. Use when you want a clean written record.

Subject

Outstanding invoice [Invoice number] — [Amount]

Body

Dear [Client name],

I am writing regarding invoice [Invoice number] in the amount of [Amount], which fell due on [Due date] and remains outstanding.

I would be grateful if you could confirm the expected payment date, or advise if any further documentation is required to process it.

The invoice can be settled here: [Payment link]

Kind regards,
[Your name]
[Business name]

Firm — final written notice

Direct, no softening. States only what you will actually do next.

Subject

Final notice — invoice [Invoice number] outstanding since [Due date]

Body

Hi [Client name],

This is a final written notice on invoice [Invoice number] for [Amount], outstanding since [Due date]. I have not had a reply to my previous reminders.

Please arrange payment by [Due date + 7 days], or reply today to tell me what is holding it up. If I do not hear from you by then, I will follow this up by phone.

I would much rather close this out directly.

How to use these templates

Replace every bracketed field — [Client name], [Invoice number], [Amount], [Due date], [Payment link], [Your name] — with the real details before you send. A reminder that still contains a placeholder is worse than no reminder at all.

Keep the email short. Clients do not need a paragraph of context; they need the invoice number, the amount, and somewhere to pay.

If you only want a single line rather than a full email, the one-sentence asks cover the same five registers. If you want the message written around your actual situation, the free reminder generator does that in a few seconds.

Subject lines that get opened

The subject line decides whether the email is read at all. Name the invoice in it — a subject that could belong to any email gets skimmed past.

Invoice [Invoice number] — [Amount] due [Due date]
Neutral and scannable. The safest default at any stage.
Quick heads-up — invoice [Invoice number] due [Due date]
Pre-due. Signals courtesy rather than chase.
Invoice [Invoice number] — now past due
Once it is genuinely late. Factual, no adjectives.
Final notice — invoice [Invoice number] outstanding since [Due date]
Only when this really is your last written message.

Avoid all-caps, exclamation marks, and words like URGENT or IMMEDIATE ACTION REQUIRED. They read as spam to filters and as panic to clients.

What makes a good payment reminder email

Be specific: Always include the invoice number, amount, and due date. Vague reminders get ignored or trigger confusion.
Keep it short: Two to four sentences is enough. The client knows they owe you money — they do not need a lengthy explanation.
Do not apologise for asking: Phrases like 'sorry to chase' undermine your position. You are owed money. Ask for it plainly.
Include a clear next step: Tell them what to do: pay, or contact you if there is a problem. Do not leave them guessing.
Escalate gradually: The first reminder is friendly. The final notice is firm. Do not go straight to aggressive — it damages the relationship unnecessarily.

Automate this instead

These templates work well once or twice. But if you are following up on multiple invoices every week, writing them manually adds up fast. PayNudge sends these messages automatically — personalised with the client and invoice details — and stops when the invoice is paid.

Frequently asked questions

What should a payment reminder email include?

A payment reminder email should include: the invoice number, the amount due, the original due date (and how many days overdue it is), a clear request to pay, and your contact details. Keep it brief — one short paragraph is usually enough.

How polite should a payment reminder email be?

The first reminder (before or on the due date) should be friendly and assume good faith. The second reminder (7 days overdue) should be firm but professional. A final notice should be direct and unapologetic. The tone should escalate gradually — never start aggressive.

Should I CC anyone on a payment reminder?

Not usually. For smaller businesses, a direct email to your contact is appropriate. If the business is larger and your contact has a separate accounts payable department, it can be worth CCing them directly on the overdue notices.
