Adherence to delivery promises

The goods receipts (consisting of the quantity and date) forecast by the purchasing department at regular intervals are transferred to inventory management and managed in the system as stocks. Each purchase order item is assigned to a date. It forms the basis for the delivery promise communicated to a customer in the event of subsequent deliveries, and for stock allocation in line with the FIFO principle. Certain items, such as furniture or electronics, are only requested from the supplier once a purchase order has been received from the end customer. The supplier has some of these non-stock items in the warehouse, so that the processing time included in the standard delivery information does not apply. For these items, the supplier reports stocks to the commercial enterprise, which also manages the quantities as stocks of inventory in its own system, using them as the basis for more reliable delivery information. This replaces the standard item-dependent delivery information for subsequent deliveries.
