Translation

クライアント / 顧客 / 依頼人 / 取引先

Meaning

A client is a person or company that pays for the services of a professional or business. 'Client' is used in service industries: law, accounting, consulting, advertising, design, and healthcare. 'The lawyer met with her client.' 'We need to keep our clients happy.' In everyday shopping contexts, English speakers say 'customer', not 'client'. The difference matters: you are a customer at a supermarket; you are a client of a law firm.

Examples

• クライアントとの会議が午後3時にある。

• その広告会社は多くの大手企業をクライアントに持っている。
  The advertising agency has many major companies as clients.
