GraysOnline consolidated four warehouses into one 323,000 sq ft DC and implemented Manhattan SCALE in 2008. The WMS delivered 15-20% productivity gains and later enabled integration of 30,000 SKUs from acquired oo.com.au within one month. Voice-directed picking with Vocollect further increased throughput while maintaining service levels during carrier transition to Toll.
