Dear [NAME, ex. John Smith],
Since we value your business greatly, I have been inspecting our invoices to ensure that we have made no errors. Unfortunately, however, I have uncovered an error on invoice #[STATE INVOICE NUMBER]. Please accept my apologies for over-billing you by $[AMOUNT].
I will immediately nullify that invoice ( [STATE INVOICE NUMBER, ex. #A423F] ) and issue you a correct one, as follows:
[LIST NEW INVOICE DETAILS, ex.
5 Magnaflux compressors @ $4,000 $20,000
Tax @ 5% 1,000
Total $21,000]
Let me assure you that I will personally inspect our invoices to you in the future to ensure that there will be no further errors. Feel free to contact me at XXX-XXXX if there are any other issues you wish me to address.
Sincerely,
[YOUR NAME, ex. Jill Jones]
