Dear Client contact's name,
I am writing about invoice Invoice number, dated Invoice date, for Amount due. Payment was due on Original due date, and according to our records it has not yet been received.
If you have already paid, thank you; please send me the payment date and reference so I can match it. If not, please pay the full amount by New date to pay by, using these details:
How to pay you
If there is a problem with the invoice, or you would like to agree a payment plan, please reply before New date to pay by so we can sort it out.
A copy of the invoice is attached. Thank you for your prompt attention.
Kind regards,
Your name or business
