Reminder email templates

1. Overdue invoice that’s a few days overdue

When an overdue invoice is unpaid and is a few days over the due date, it is appropriate to send a reminder email. The first reminder email should be courteous and polite in tone.

If you charge interest or apply charges on late payments as part of your terms, it maybe a good time to remind them that these could become due.

First overdue invoice Reminder Email template:

Subject: <your company name> – Payment due for <invoice reference number>

Dear <customer name>,

Further to our previous correspondence, we are contacting you in relation to the above invoice. We though it prudent to send a polite reminder that we have not yet received payment.

<Invoice ref no> and <invoice balance>

Payment of this invoice was due on <insert due date>. We would greatly appreciate it if you could pay this or advise as to when it will be paid.

If there are any issues with regards to this invoice, please do not hesitate to contact us for clarification.

3. Seriously overdue invoice 

At this point, you will likely have contacted your customer by phone also, requesting payment of the overdue invoice. If the invoice is still unpaid and there has no explanation then a final reminder needs to be sent.

This gives your customer one final opportunity to get the overdue invoice paid. If this is a B2B invoice then you are entitled to add interest and compensation under the late payment of commercial debts act.

Final reminder email:

Dear [customer name],

Further to our previous correspondence, We are contacting you again with regard to the following overdue invoice:

<invoice ref number> / <invoice balance>

This invoice was due on [due date] and remains unpaid. We have not received payment nor had any communication from you in relation to this despite our best attempts.

If we do not receive payment within 7 days then we are left with no alternative but to pass this to our Debt Recovery Agents for immediate action to recover the monies owed to <your company>. You may also be liable for debt recovery costs accordingly.

We hope this will not be necessary and look forward to receiving full payment without the need for debt recovery action. 

We have attached a another copy of the invoice for your reference. 

Kind regards,
<sender name>
