Abstract: The system of this invention manages customer orders using vendor supplied software systems interfaced on a real-time basis to touch the data in each system on a real-time basis. In effect, there is horizontal communication between the various components of the system such as inventory, purchasing, order management and receipt, logistics and inventory to have continual data flow without using a vertical software interface. As a result, customer orders are received on a real-time basis using screens that are user friendly to promptly take orders, to verify customer data and to verify the ability to meet those orders. Transmission of documents within the system is minimized thereby making it more efficient, timely and cost efficient.
