A commercial business letter is a letter written in formal language, usually used when writing from one business organization to another, or for correspondence between such organizations and their customers, clients and other external parties. The overall style of letter will depend on the relationship between the parties concerned. There are many reasons to write a business letter. It could be to request direct information or action from another party, to order supplies from a supplier, to identify a mistake that was committed, to reply directly to a request, to apologize for a wrong or simply to convey goodwill. Even today, the business letter is still very useful because it produces a permanent record, is confidential, formal and delivers persuasive, well-considered messages.
Parts of a business letter
The block format is the simplest format; all of the writing is flush against the left margin.
