A freelancer provides their services as an independent contractor, which means they don’t work as part of your business but from the outside. This is great if you consider the expenses and payroll taxes involved in having employees: Health insurance, social security, compensations, unemployment insurance, office space, equipment, etc. Freelancers save you all of these as they have to mind all of the expenses and taxes by themselves. Of course, they consider these to set their rates but it’s not the same as if you were covering the total of them.
