Difference Between Memo and Letter

A memorandum or shortly known as a memo is a precise official note, used to inform, direct or advise the members within the same organisation. However, the business deals with a number of external parties such as customers, clients, suppliers, government agencies, manufacturers, societies, etc. for which a different tool of communication is used, called as a business letter. A letter refers to a brief message sent by the company to the person or entity, which are outsiders.

Large corporations require an effective system for communication of information and messages, promptly, within and outside the organisation. In this context, the telephone is one of the easiest and convenient ways for instant communication, but when it comes to evidence, written modes are considered best. Written records include memos, notes, letters, circulars and orders, which are used by the organisation.
