Thank you for selecting me to edit your document. I hope you are pleased with the revisions I have suggested. One item I was not sure about was the use of the word "supplement" when referring to what I believe must have been a supplemental invoice. I understand that it may be standard industry terminology, but was not sure if it would be understood by your intended recipient. I replaced "supplement" with "supplemental invoice," but of course if you are sure the letter's recipient will understand the term "supplement,"&nbsp;please feel free to disregard this suggestion.<br /><br />Please let me know if there is anything else I can help you with.
