Ecommerce logistics is characterised by the presence of several functions and processes that do not take place in the traditional replenishment of stores or depots. The key difference is the atomisation of throughput volumes into much smaller orders to many more destinations with much greater flexibility. This is most notable in the transportation of goods to people’s houses, collection points or lockers instead of a small number of deliveries to retail outlets. The smaller order profiles require new ways of picking, packing and despatching goods in the warehouse. Returns are another significant by-product of ecommerce, particularly in the fashion sector, where unwanted items are returned to the warehouse to be processed for refunds and put back into stock if required. Stock has a longer residence time in the warehouse and therefore must be protected from damage, typically with polythene bags.
