If that vehicle is available then the customer would then sign the necessary documents which he would receive from the agency. After this has been completed the vehicle would be classed as being rented and a new rental record is added to the agency’s file if the customer is new or a file drawn to be updated if the customer is an existing customer. The date out of the vehicle would be tabulated by the business and the date returned left empty (when the vehicle would be returned the agency would update their files by filling in the date returned field). The agency would then bill the customer and the bill paid by the customer
