In order to become an entrepreneur in the Netherlands you do not necessarily need to establish a business. You can also become a freelancer or a ZZP'er. ZZP (self-employed with no personnel) is not an official understanding. The law for example does not state exactly what a ZZP'er is. In practice, the term is used for the self-employed who offer their services to various clients. For example a bricklayer who works for various companies. Or a journalist, or IT specialist who hires out their services. You are a business of your own, or in other words, a one-person business.
