Different from the business letter, company memo is less formal and more friendly. Company memo can be divided into two main types, one is for the internal communication between employees in the enterprise, and another one is for the external communication with the individuals from other companies or organizations. There are many purposes of using memos, such as conveying the message, announcements and ideas. However, company memo is not a good choice if the content is very confidential and sensitive. We offer Company Memo Template, Crew Deal Memo and other files as templates for your reference.
