Huge cost savings can be achieved here. The order lists are read into the sorting system and the sorting can begin. The cost savings come from a more efficient picking process. Instead of picking each order separately, we now switch to batch picking. This means a number of orders for a product are picked in one go and loaded into the sorter. This allows more picking to be done with far fewer people. Each order is assigned to an exit (chute) and is assembled. Each order can vary from 1 item to many hundreds.
