Item Name should be correct and well thought through, it should follow a consistent pattern
Item name for stone should have size, quality and shape in name to be able to search, eg: Ruby Round AAA 2 x 3
Item name for metal should have quality in name to be able to search, eg: Yellow Gold 9K
Item Categories should be correct.
Main Unit should be selected as per usage and not as per purchase. eg: Purchased in meters, but used in cms, then the unit should be cms
Main Unit in the master cannot be changed after first item is received in the inventory.
Main Unit in the master should match while adding price
Track inventory is important for indicating the system that Inventory needs to be recorded, this is On by default for Design and Raw Material and Off for General Item
If Track inventory is manually turned off while creating the item, then system will not create a new batch for that item when it is received
