A person who runs a business on his own account is called a sole trader. This term refers to an individual who owns and operates their business independently, without forming a company or corporation. They are solely responsible for all aspects of the business, including decision-making, profits, and losses.

Here's a simple way to understand this:

Sole: This means "one" or "single," indicating that there is only one person in charge.

Trader: This refers to someone who engages in selling goods or providing services.

Therefore, a sole trader is someone who runs their business independently and takes full responsibility for its operation. They do not have partners or additional directors in the business.
