Overdue invoice email writer
- Time
- About 3 minutes
- What you'll get
- A subject line and email for the stage you are at, the next step and when to send the next one.
Fill in the invoice, say how late it is and pick a tone. You get a payment reminder email ready to send, the next step and when to chase again. Free, with no sign-up.
A good overdue invoice email is short and specific: the invoice number, the amount, the due date, a copy attached and one clear ask. The first reminder assumes it slipped through. Each one after that is a little firmer, with a date to pay by, until a final reminder says what happens next.
Nothing you type is saved or sent anywhere. It stays in this browser tab, and leaving the page clears it, so copy or print your email before you go.

How to use the overdue invoice email writer
- Fill in the invoice. The client's name, the invoice number, the amount and the currency (pounds, dollars or euros), and the due date.
- Say how late it is. Leave it on “work it out from the due date”, or pick the stage yourself: due soon, 1 to 7 days, 8 to 30, 31 to 60 or more than 60 days late.
- Pick a tone. Friendly, firm or final. The tool suggests one for the stage, and warns you if your choice is unusual for it.
- Read it through. Fill in anything left in [square brackets], such as what you'll do if a final reminder is ignored. Only promise what you'll actually do.
- Copy or print it. “Copy the email” gives you the subject line and the email as text. The copied text ends with a line saying where it was made, so delete that before you send. “Print” prints the email and the next steps on one page.
An example payment reminder email
A made-up example: Tamberly Studio, our fictional design studio, chasing invoice TS-1042, which is 12 days late. The tone is firm, as suggested for 8 to 30 days late.
Subject: Invoice TS-1042 is 12 days overdue: please pay by 19 November 2026 Hi Sam, I am following up on invoice TS-1042 for £1,850.00, which was due on 31 October 2026 and is 12 days overdue. I have attached a copy. Please pay the full £1,850.00 by 19 November 2026, or reply with the date it will be paid. If there is a problem with the invoice or the work, tell me now so we can put it right. Kind regards, Grace Mensah, Tamberly Studio
Next step: Phone the person who approves payments, ask what is holding it up and agree a date. Put the date in writing.
When to send each reminder
A simple timetable to start from. Move it earlier for a large amount or a new client, and use your own payment terms if they say something different.
| Stage | When to send | Tone | What else to do |
|---|---|---|---|
| Not due yet, or due today | A few days before the due date | Friendly | Send the friendly reminder the day after the due date if it has not arrived. |
| 1 to 7 days late | The day after the due date | Friendly | If there is no reply in a week, send the firm reminder. For a large amount, phone as well. |
| 8 to 30 days late | About a week after the first reminder, then weekly | Firm | Phone the person who approves payments, ask what is holding it up and agree a date. Put the date in writing. |
| 31 to 60 days late | When the agreed date passes, or a month after the due date | Final | Send the final reminder with a pay-by date, and hold new work on the account if your terms allow it. |
| More than 60 days late | Once, with a clear pay-by date | Final | If the pay-by date passes, choose a formal step: a letter before action, a debt recovery service or a small claim. Take advice first if you are unsure. |
Common mistakes when chasing a late payment
- Leaving out the details. Without the invoice number, amount and due date, the client has to go looking, and the email waits. Attach the invoice every time.
- Writing to the wrong person. The person you did the work for often isn't the person who pays. Ask who approves payments, and copy them in.
- Waiting too long to start. A polite reminder the day after the due date is reasonable, and much easier to send than one two months later.
- Jumping to a threat. A final reminder on day three can cost you a good client. Go up a step at a time.
- Threatening what you won't do. If the final reminder says you'll pause work, pause it. Empty threats teach a client to wait.
- Chasing only by email. Once it's a week or two late, phone as well, and put what you agree in writing.
Late payment interest: UK businesses
If another business pays you late, UK law usually lets you claim statutory interest of 8% plus the Bank of England base rate, and a fixed sum towards the cost of recovering the debt: £40 for a debt under £1,000, £70 from £1,000 to £9,999.99 and £100 for £10,000 or more. You can't claim statutory interest if your contract sets a different rate. The tool can add a line about it to a firm or final email if you tick the box. GOV.UK sets out the current rules. The rules are different in other countries, and this isn't legal advice, so check what applies to you before you claim.
Make chasing a set routine
One email gets one invoice paid. A set routine gets them all paid: the same chase dates, the same wording and one person who owns it. The Overdue Invoice Chase Script in the Money and Data Launchpad (Mini Vault, $75) gives the chasing a set order and wording, with a cash gap plan for the weeks when money is short. Like every SystemaFlow™ system, it's a done-for-you template in Word and PDF, not software.
Common questions
When should I send a payment reminder?
For a large invoice or a new client, a few days before the due date. Then the day after it is due, and about once a week after that, a little firmer each time. Phone as well once it is more than a week or two late.
How do I write a polite overdue invoice email?
Keep it short and specific: the invoice number, the amount and the due date, a copy attached and one clear ask. Assume it slipped through, and make it easy for them to reply with a date.
What should a final reminder say?
That it is the final reminder, the full amount, a date to pay by and what you will do if it isn't paid. Only say what you will actually do, and keep the tone calm.
Can I charge interest on a late invoice?
UK businesses: if another business pays you late, you can usually claim statutory interest of 8% plus the Bank of England base rate, and a fixed debt recovery sum of £40, £70 or £100 depending on the size of the debt, unless your contract sets its own rate. GOV.UK has the current rules. Elsewhere the rules differ. This isn't legal advice.
Should I phone or email?
Both, once it is more than a week or two late. Email gives you a written record, and a call finds out what is really holding the payment up. Put anything you agree on the phone in an email afterwards.
Is what I type saved?
No. The client's name, the invoice details and the email stay in this browser tab and aren't sent anywhere. Copy or print the email before you leave the page.
