We highly value your business, and I myself look after our invoices to make sure that there is no error. However, I regret to inform that we have encountered an error on invoice #[MENTION INVOICE NUMBER]. I would like to send my apologies for over-billing you by $[AMOUNT].
This is to inform you that I will immediately invalidate that invoice ([STATE INVOICE NUMBER, ex. #IN123]) and issue you a fresh and correct one, The invoice is as follows:
[LIST DETAILS OF NEW INVOICE, ex.

I assure you that I from future I will personally check our invoices send to you. We will make sure no further errors occur from our end. For any doubts or clarification please do not hesitate to contact me at XXX-XXXX.
