One of the biggest challenges faced by retailers during the holidays is a dramatic increase in order volume. For the period including Black Friday and Cyber Monday, companies can see those volumes increase by as much as 400 percent. To meet this demand, many businesses must bring in temporary warehouse workers and get them trained and working quickly. The tablet-based Inventory Management App, which runs on the Warehouse Mobile Solutions WarehouseOS, is helping companies meet this challenge. Warehouse Mobile Solutions CEO Tim Hoj said the easy-to-navigate user interface means warehouse personnel need almost no training before performing warehouse tasks such as receiving, putting away, picking and packaging.
