Send an adjustment letter when you want to notify the letter recipient about an adjustment to something, such as an adjustment on a bill or invoice. You will sometimes write a letter like this on behalf of someone else, such as your child, your elderly parent, or someone who has placed you in charge of his or her affairs. Sometimes, adjustment letters are professional in tone and style but can also be more informal and conversational, depending on the situation and context. The style and wording you use in a letter depend on the specific circumstances.
It is generally best to keep letters as short and concise as possible while still communicating the necessary information. Feel free to customize and modify any of these letters according to your individual needs.
NOTE: In all letters, brackets indicate information that you should fill in. Remove the brackets when you have modified the text to your liking.
