QB does not handle bin locations for inventory parts, the best you can do is create a custom field and use that. Once you create the custom field for an inventory item it will be there for all items in inventory.

Once you have the field created, bring up the item list, right click on the column titles and select customize columns, find the bin location field in the left side list, highlight it, click add then move it up the list to where you want it to appear.
