When should I send an overdue invoice letter?

You've received a purchase order from a customer, sent the items, and issued an invoice – yet you haven't received payment. What do you do now?

Most of the time, late payment can be easily settled with a quick email to your customer, gently reminding them that payment is overdue. When that doesn’t work, however, or you get no response, a letter in the post can help to formalise the situation. Make sure you’ve got an up-to-date address for correspondence, and keep a copy (and record) of everything you send and receive.

To get you started, here’s what an outstanding payment letter should include, when to send a ‘nudge’, and how to take further action (if necessary).

What should a late payment letter include?

Hopefully you’ll only ever need to send one polite nudge for late payment. But if not, you may need a couple of other templates to get the message across, including a firm reminder and a final notice letter.

These are the basic details each letter needs to include:

Late payment letter 1: polite nudge

• your company name and address
• recipient’s name and address
• today’s date
• a clear reference and/or any account reference numbers
• the amount outstanding
• original payment due date
• a brief explanation that no payment has been received
• next steps (you could give the recipient the opportunity to contact you and/or pay within a specific number of days)
• payment options
• reference to your payment terms

Late payment letter 2: firm reminder/late payment charges letter

• your company name and address
• recipient’s name and address
• today’s date
• a clear reference and/or any account reference numbers
• the amount outstanding
• a reference to your polite nudge or last communication
• a brief explanation that payment is still outstanding, and any charges that may be added in line with your payment terms (and current government legislation)
• next steps, including a cut-off payment date
• payment options
• reference to your payment terms

Late payment letter 3: final notice/letter before action

• your company name and address
• recipient’s name and address
• today’s date
• a clear reference and/or any account reference numbers
• the breakdown of the total amount outstanding, including any additional charges/interest
• a reference to your reminder letters or last communication
• a brief explanation that payment is still outstanding and now in breach of your payment terms
• explanation of any further costs added
• next steps, including a final cut-off date and consequences for failure to pay (this will depend on your debt recovery arrangements)

Outstanding payment letter template

Here’s a late payment letter template, giving a reminder of the amount outstanding and due date, plus next steps.

You’ll need to edit this according to your business and circumstances, for example it might be more appropriate to mention a specific invoice that hasn’t been paid, rather than an overdue account balance.
