Advising is the practice of assisting a client in improving their systems and processes over time. Advisers often work with the same company long term, and they may take on leadership roles within the company. Sometimes, companies think of advisers as mentors because they are usually very experienced in their industries. Advisers typically aim to give their clients direction to help them achieve their major goals and overarching purpose. Small businesses or startups may find hiring an adviser especially useful to gain advice from an expert and get help creating a strategy for long-term success.

Advisers can specialize in many different industries, and common advisory jobs include financial advising, business advising, brand marketing, and IT advising. Some of the most typical responsibilities of advisers can include evaluating company operations and market research, monitoring accounts, preparing reports and identifying potential opportunities. Advisers may also work to design new strategies and help companies implement them.
