Rev-A-Shelf, a custom storage solutions manufacturer, replaced a paper-based inventory system with Epicor ERP and embedded WMS.

Results included near-perfect physical inventory accuracy on $8M of stock, reduced count time from four days to 6.5 hours, 25% productivity gains, and inventory turns rising from 2x to 8x per year.
