This can be a hard question to answer. But take, for example, a small company that has about twenty computers and one IT person who works part-time. For less than the wages the part-time IT person is being paid, you could have an entire staff of trained and certified network technicians monitoring and maintaining your network. The increased productivity and revenue will more than pay for the costs, no matter the size of the company. Even large companies with many IT professionals on staff can benefit from having a team of extra people ready to consult if needed.
