A computerized order entry system for the placement of an order by a user via a terminal having a display is disclosed. The system includes a data capture mechanism for capturing order information and a storage device for storing the order information captured through the data capture mechanism. The system also provides a user interface for providing the user with access to a plurality of buttons representing a plurality of corresponding order entry functions. Each button is associated with an order entry function window having at least one data capture field into which order information related to the corresponding function may be captured. The user interface includes a mechanism for automatically routing the user to a particular order entry function window upon selection of the associated button. With such a configuration, placement of the order is substantially user-driven.
