Abstract: A programmed data control server compiles a database of product and materials order information from all available suppliers, allows users Internet access to search and order from the database and arrange for delivery or pickup, and inputs and tracks orders to selected suppliers via the Internet. Customers utilize a touch screen on a remote electronic device, which may be a handheld dedicated device exclusively connected to the data control server or other Internet connected device, to search the data control server, save desirable repeat order information, search for special offers, place orders, set up delivery or pickups, and track orders through the data control server.

Abstract: An electronic estimator has a clipboard size electronic touch screen. The contractor can draw on it, use it as a touch screen to select materials for a job, estimate costs including a running total of costs for a job, and input all client info. After initial contact by a potential customer, the contractor can input the client information including location and use a global positioning system (GPS) to travel to the client location. The contractor can use it to order materials for the job from the supplier.
