Methods, systems and apparatus for determining a current state of an order book for order request reconciliation. A customer inputs an order request for a desired quantity of items to be shipped to a recipient into the system. A supplier inputs a shipment quantity of any such previously shipped items into an input table, while a recipient inputs into another table a receipt quantity of any such received items. These input shipment and receipt quantities are then transmitted to a reconciliation program of the system for determining an in-transit quantity that is used along with the receipt quantity to generate an updated, current state of the order book. This current state of the order book substantially avoids any over-shipments, under-shipments and unwanted inventory returns. A Materials Requirement Planning component then generates an order book reconciliation output table for viewing by users using the current state of the order book.
