Writers, job seekers, managers, and students often pause over one tiny choice: Onsite or On-Site. The terms look almost the same, yet hyphen, one word, two words, workplace, formal writing, business email, and physical location all affect the best choice. In everyday American writing, onsite is common and easy to read. However, on-site still feels safer in formal documents. Meanwhile, on site works best when you mean someone or something is physically at a location. This guide keeps the rules simple, so your emails, job posts, reports, and service pages sound polished.
