Freelancers work for themselves and provide services to clients, invoicing them for the work they do. The clients they have depend on the services they offer, and can be individuals or companies. Full-time freelancers often have multiple clients at once, and common services include writing, editing, graphic design, web design, marketing, programming, accounting, and bookkeeping. Freelancing is a good fit for those who want to be their own boss and are willing to market themselves to meet their income goals.
