Bill and hold

A bill and hold transaction occurs when a company recognizes revenue before delivery takes place. Normally a revenue is not recognizable until goods are delivered or services are rendered. Exceptions are made when a customer specifically requests that the vendor delay delivery  and has a legitimate business reason for the request.
