There are many reasons why a small or medium-sized business might want to engage an IT consulting firm. One of the most powerful is the fact that IT consulting firms are able to offer small companies a level of service that could never be attained by in-house staff. This circumstance results from the fact that a small business would very rarely be able to hire an entire IT department. Indeed, information technology specialists can be so expensive to hire and retain that some businesses may not even be able to afford a department of one person.
A key solution to this dilemma is for a small business to contract with an IT consulting firm. Such an arrangement will give the company access to a large team of specialists that can offer advice on any number of issues. To have all that expertise on-staff would be prohibitively expensive, but an IT consulting arrangement can bring it within reach even for a small business with a modest IT budget allocation.
Another advantage of IT consulting is the fact that IT companies working to offer advice are very experienced with producing cost estimates. An in-house staffer may or may not be able to generate an accurate approximate cost for a new IT project; this is only to be expected, since he or she may never have put together a similar project before. A typical IT consulting firm will already have worked out cost figures in the past for somewhat similar arrangements, and can start from a position of knowledge and experience rather than ignorance.
