Maximise and optimise all available space. Rather than expand the footprint of your warehouse, consider better use of vertical space. Adding taller storage units and the right equipment to pick and store material can help you keep more in the same square footage, rather than adding expansion costs. In addition, think about the type and variety of shelving used. Storing small items on pallet racks wastes space, and makes it easy to misplace items. Rather than using the same racks throughout your warehouse, you may need various types of shelving for different materials. Also, try using standardised bins to help keep shelves neat and orderly.
