Next to starting a letter, the most difficult part is to finish it effectively. There are two elements top finishing a letter: an ending, called the closing line; and an appropriate sign of, called the complimentary close.

ENDING RIGHT

It is important in business letters to make your point clearly, particularly at the start and at the end, so that your reader is aware of what it is you want. For example with a follow up letter you generally want to encourage the relationship to continue and so you would give it a very different finish from complaint letter, where the ending of the letter would demand action, a remedy or an apology.
