An independent person or legal entity, which acts on behalf of another (“Principal”). In international transactions, this term normally refers to a sales representative who prospects on behalf of a foreign principal, earning a commission on sales eventually concluded between the principal and the ultimate client. This is distinguished from sales through employees and subsidiaries – that are not independent – or through distributor´s buying and reselling in his or her own name. Sales Agents should also be distinguished from buying agents, as their respective rights and obligations are quite different. In international trade, relationships between agents and their clients (principals) are regulated through a Model of International Agency Contract. See brokerage; distributor, sales representative.
