I am a wholesaler. Our warehouse is divided into multiple locations( apprx 10ftx10ft size) and we store SKUs ( many) in each location. Currently, we track this in excel sheet. Our warehouse people give given location details of a particular product to pick from. There they locate the item from specified location and then load the item. 

I was trying the demo. I do not see any option to specify locations in a warehouse. Do let me know if it is available in Zoho.
