It is very expensive to hire a worker. Some of the many complications entailed include the following: a way to interview and screen the potential employees; bargaining of terms and conditions; expenses; healthcare coverage; insurance coverage; and necessary vacations. On the other hand, you may easily engage a freelancer to do a work in only one day and then go without a trace. Nevertheless, it is possible to attract a freelancer with a short-term commitment and to specialize in a given field and then to attract another individual with a different environment of skills to work on a different project. In conclusion, freelancers are efficient and flexible. Scale Startups Without Hiring Internally by outsourcing freelancers so as to pick up the workload as it arises.
