In mainland European jurisdictions, a person who acts in their own name for the account of a principal. The principal is contractually bound to deliver (through the commissionaire) the goods sold to the customer; the commissionaire is contractually bound to the principal to remit the price received to the principal.

This relationship is similar to that of an agent for an undisclosed principal in the UK.
