A major advantage of business memos is that they are inexpensive to create. Even when businesspeople physically print the memo, doing so usually costs the company far less than it would to halt work entirely to have a formal meeting about what the memo addresses. If businesspeople send the memo via email, the company also is able to communicate without without having ink and paper expenses, and there is no physical disposal of the memo papers necessary for which the company could be charged.
