Business consultant

A business consultant is a professional who provides professional or expert advice in a particular field, such as security (electronic or physical), management, accountancy, law, human resources, marketing (and public relations), financial control, engineering, science, digital transformation, exit planning, or any of a large number of other specialised fields. The term "consultant" comes from the Latin consultare, which means "to discuss."

A consultant is often someone who is an expert or a professional in a certain field and has a broad range of knowledge in relation to a particular topic. The time, money, and resources of their customers may all be maintained thanks to the work of consultants. Outside of the field of medicine (where the word "consultant" refers to a certain level of medical practitioner), the function of a consultant may be classified as one of two broad types.

A person who works inside an organisation but is accessible to other departments or people for consultation on matters pertaining to their areas of expertise is known as an internal consultant (acting as clients).

An external consultant is a person who is engaged externally (either by a company or some other agency) and whose knowledge is supplied on a temporary basis, often for a fee. This kind of consultant is typically hired by a company. As a result, this sort of consultant often works with a variety of different customers throughout the course of their career.

Clients have access to deeper levels of expertise than it would be feasible for them to retain in-house when working with a consultant, and they have the option to purchase only as much service from the outside consultant as they desire, which contributes to the overall positive impact of consulting.
