After moving to a larger facility, the retailer replaced manual sortation of small items with a bi-directional sweeper sorter system. The solution uses wave picking to batch orders, then routes them through 20- and 80-destination sorters for final separation. Results include a 40 percent reduction in annual labor costs, ROI in under two years, and improved order accuracy.

Labor reduced from 27 to 16 full-time equivalents with shorter workdays
