When it comes to business, some mistakes are clearly more serious than others.

Some errors and miscalculations can have significant financial or legal implications.

However, even when the mistake is viewed by the company as insignificant it should never be thought of in those terms when dealing with customers or crafting an apology letter.

Customers need to know that you are taking the situation seriously and are working to correct things on their behalf.

In fact, some mistakes, when handled correctly can benefit a company in terms of both customer loyalty and customer retention.
