Write a letter expressing apology for accounting errors and past due notices.

Dear Sir,


This is to express apology and offer an explanation for what went wrong in our accounting department. We hope that this letter will serve to resolve our recent difficulties.

We shall be grateful if you can appreciate the fact that it has taken some time to find out exactly what occurred, and, that is the reason for the delay in response from our end.

Apparently, your payment was received in a timely fashion, but it was credited to an account which bears a similar name to yours. Therefore, we commenced sending you our standard notices requesting payment, in keeping with our routine policy. Even after the posting error was rectified, our accounting department failed to notify our credit department, as a result you continued to receive our services.


Thanking you.


Sincerely,
