Parts of a Business Letter. Business Letter is a letter which is used by organizations to communicate in a professional way with customers, other companies, clients, shareholders, investors, etc. Business letter uses formal language and a specific format.
Writing for a business audience is usually quite different than writing in the humanities, social sciences, or other academic disciplines. Business writing strives to be crisp and succinct rather than evocative or creative; it stresses specificity and accuracy. This distinction does not make business writing superior or inferior to other styles. Rather, it reflects the unique purpose and considerations involved when writing in a business context.
