Payment Reminder Emails: 6 Templates for Overdue Invoices

The invoice was due five days ago. You have heard nothing, the money has not arrived, and you are staring at a blank email trying to sound firm without sounding desperate, or rude to a client you would like to keep.

Most late invoices are not refusals. They are stuck: sent to the wrong inbox, waiting for a signature, missing a reference, or simply forgotten. A good reminder gets them unstuck, and a schedule of reminders means you never have to decide from scratch what to say. This guide gives you both.

When should you send a payment reminder?#

Decide the schedule before the invoice goes out, so chasing becomes routine rather than a mood. This one works for most freelancers on 7 to 30 day terms:

When you send the invoice, add the dates to your calendar so the reminders do not depend on memory. If the client pays at any point, stop and send a thank-you.

What should every payment reminder include?#

Whatever the tone, each email should let the client pay without opening another message:

• The invoice number in the subject line, so it can be searched and forwarded.
• The amount, with its currency. "$3,600" or "EUR 3,600", not "the balance".
• The original due date, and from the third email on, how many days overdue it is.
• The invoice itself, as a link or a fresh attachment. Nobody should have to dig for the original.
• How to pay: bank details, or the method you agreed.
• One clear ask with a date: "Could you confirm the payment date?" or "Please pay by Friday 23 October."
• Who to contact if something on the invoice is wrong.

Send it to the person who pays, not only the person who hired you. If your contact passed the invoice to an accounts team, copy that team in, and reply in the same email thread each time so the whole history travels with it. If you have not sent the invoice itself yet, how to send an invoice covers that first email.

6 payment reminder email templates#

Replace everything in square brackets. Keep the dates real: "by Friday 23 October" works better than "soon".

1. Friendly heads-up (3 days before the due date)

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

Hi [name],

A quick note that invoice [number] for [amount] is due
on [due date]. You can view it here: [invoice link]

If it needs a purchase order number or anything else
to go through your system, let me know and I'll send
an updated copy today.

Thanks,
[your name]

2. Due today

Subject: Invoice [number] for [amount] is due today

Hi [name],

Invoice [number] for [amount] is due today, [due date].
Here it is again: [invoice link]

If it's already on its way, thank you, and please
ignore this. If not, could you let me know when it's
scheduled to be paid?

Thanks,
[your name]

3. Just overdue (about 3 days late)

Subject: Invoice [number] is now overdue

Hi [name],

I haven't received payment for invoice [number]
([amount], due [due date]) yet, so I wanted to check
it reached the right person. Here's the link again:
[invoice link]

Could you confirm the date it will be paid? If
anything on the invoice needs changing, tell me and
I'll fix it straight away.

Thanks,
[your name]

4. Second reminder (7 to 10 days late)

Subject: Second reminder: invoice [number], [X] days overdue

Hi [name],

I'm following up on invoice [number] for [amount],
which was due on [due date] and is now [X] days
overdue: [invoice link]

Please could you arrange payment by [date, about a
week from now], or reply with the date it will be
paid? If someone else handles supplier payments,
could you forward this or copy them in?

Payment details: [bank details or agreed method]

Thanks,
[your name]

5. Firm reminder (about 14 days late)

Subject: Overdue: invoice [number], payment needed by [date]

Hi [name],

Invoice [number] for [amount] is now [X] days past its
due date of [due date], and I haven't had a reply to
my last two emails: [invoice link]

Please arrange payment by [date]. As set out in our
agreement of [date], late payments [incur interest at
X% a year / a late fee of amount], which I will add if
payment has not arrived by then. I'm also pausing new
work on [project] until the account is up to date.

If there's a problem with the invoice or the timing,
call me on [phone] and we can sort it out.

[your name]

Only mention a fee or interest you are entitled to charge, either because your agreement says so or because the law gives it to you (see the last section).

6. Final notice (about 30 days late)

Subject: Final notice: invoice [number], [amount] overdue since [due date]

Dear [name],

This is a final notice for invoice [number] for
[amount], due on [due date] and now [X] days overdue.
I wrote on [dates of earlier reminders] and have not
received payment or a payment date.

Please pay the full amount by [date, 7 days from now].
If payment has not arrived by then, I will [next step,
for example: refer the debt to a collection agency /
start a court claim] without further notice.

Invoice: [invoice link]
Payment details: [bank details or agreed method]

If you believe this amount is not owed, please tell me
in writing by [date].

[your name]
[business name, address, phone]

Name only a next step you are ready to take. An empty threat teaches a client that your deadlines are optional.

How should a payment reminder sound?#

Polite, short and specific. The goal is to make paying the easiest thing for the reader to do next, not to show how you feel about it.

A few more habits help:

• Assume an oversight first. The first two reminders should read as if the delay is a mistake, because it usually is.
• Escalate one step at a time. Each email a little firmer than the last, with nothing new sprung on the client.
• Write during working hours on a weekday, when the person who can act on it is at their desk.
• Keep a record. Save every email and note every call. If it ever goes further, the timeline is your evidence.

When should you call, message or pause work?#

After the second email with no reply, pick up the phone. A short script:

Then confirm what they said in a one-line email: "Thanks for the call. As discussed, invoice [number] will be paid on [date]." If you normally talk to the client on a chat app, a short message with the invoice link works too, but follow it up by email so there is a record.

If the client says they cannot pay in full, agree a plan in writing rather than waiting: for example, two payments of $1,800 on 30 October and 13 November.

Pausing new work is the strongest lever most freelancers have. Check your contract first, tell the client in writing, and say exactly what restarts the work: "I'll resume as soon as invoice [number] is paid."

Chasing invoices with BillBee.work#

BillBee.work, a free invoice maker for freelancers, does not send emails or reminders, so the templates above go out from your own email account. What it does is make the chasing easier to manage:

• Overdue at a glance. An unpaid invoice is marked overdue automatically once its due date passes, and the dashboard shows the overdue count and the amount still pending. A quick look on Monday morning tells you who to chase.
• One link for every reminder. Each invoice has a share link the client opens in a browser without signing up. Paste the same link into every email in the thread, and the client is always one click from the invoice. On Pro, they can also download the PDF from that link.
• Payment details on the invoice. Your bank details and terms line, saved once in your profile, print on every invoice, so the "how to pay" part of each reminder is already there.

When you share a new invoice, put your reminder dates in your calendar at the same time. Mark the invoice paid when the money arrives, so the dashboard stays accurate.

What if the client still doesn't pay?#

After the final notice, your options depend on the amount, the relationship, and where you and the client are based. This is general information, not legal advice:

• UK, business clients. You can claim statutory interest of 8% plus the Bank of England base rate, plus a fixed recovery sum of £40, £70 or £100 depending on the size of the debt, unless your contract sets a different interest rate. gov.uk says to send a new invoice if you decide to add interest. Net 30 payment terms has a worked example.
• UK, a larger customer. The Small Business Commissioner helps small businesses and the self-employed with unresolved payment disputes with larger customers.
• UK court claims. In England and Wales you can make a money claim through the county court, often online, and gov.uk notes that mediation could be quicker and cheaper than going to court. Scotland and Northern Ireland have their own processes.
• EU. Your Europe says you can charge late payment interest and a flat €40 compensation fee for each invoice paid late (more in some countries) by sending your customer an invoice that includes them.
• US. Small claims court is the usual route for smaller amounts; check your state court's website for its limits and fees. Freelancers in New York City can also file a complaint with the city's Department of Consumer and Worker Protection.

A collection agency or a letter from a solicitor or lawyer are the other common steps. Weigh the cost and time against the amount owed before you start.

Then fix the cause for next time. How to get clients to pay on time covers deposits, shorter terms and the habits that mean you send fewer of these emails. The freelancer's guide to invoicing covers the rest of the process.
