The Purchasing Department is charged with the management of the entire product range and ensures that the central warehouse and those of the branch offices remain properly stocked. The orders being delivered to the central warehouse every day are based on the number of articles sold and the minimum stock. Centralised purchasing in large batches allows us to negotiate discounts, resulting in better prices and service. Of course, for rush orders the branch offices can also buy decentrally. All stock orders are generated automatically, so they are made specifically for each branch office, with the quantities in stock being determined by periodic adjustment of the minimum and maximum stocks. The replenishment process is fully sales-driven, which means that articles that have been sold are automatically ordered again. The goods are shipped to the branch offices by night, to ensure optimum stocks at the beginning of each day.
