An outside individual who supplies professional advice or services to companies for a fee.
Consultants offer expert advice in their specific field. There are various types of consultants, such as management consultants, marketing consultants, strategy consultants and many more. Often consulting firms provide companies with an outsider perspective - assisting senior management or project management teams to address specific areas of focus.
Whatever areas of expertise they cover, organizations can expect professional and reliable insights from leading consulting firms. A new field that has been approached in recent times is the marketing strategy towards social media and how to make the most from online ads.
