Business writing is straightforward and direct, not excessively formal.
Buzzwords that do not add precision or clarity should be avoided: words like no-brainer, win-win, value-added, for example, are not helpful to the reader.
Personal pronouns are acceptable; if you are using the “you” pronoun in the plural, you want to be sure you are, in fact, addressing all readers. If you speak for your company, you will want to use the “we” pronoun rather than “I.”
Language must be sensitive to possible offensiveness in interpretation; unless your point is specific to a particular group, readers’ class, race, gender, ethnicity, ability, sexual orientation need not be referred to directly or indirectly.
Always be concise: instead of writing, “at this point in time,” simply write, “now.” Rather than use the passive voice, use the active: instead of writing, “This report was prepared to infirm our customers,” write, “We prepared this report to inform our customers.”
Business writers rely on the CMS, The Chicago Manual of Style, system of documentation OR the Publication Manual of the American Psychological Association, the APA. Either offers professional guidelines for formatting and citing work.
