Volume is super important for any shipper and the product dimensions are already in the system. So Length*Width*Height / 1728 = Cubic Feet (volume) of the shipment.
Item volume is super important for any inventory company - we've just started using Dear and it seems such a silly omission that the product volume is automatically calculated based on the dimensions already in Dear!
This should be on the Delivery Docket/Packing Slip, AND in the Product view , under Dimensions....
@Caroline - there is no unit of measure specified in Dear anyway , so you can just consider it to be whatever is the normal unit of measure
(maybe it's changed since your comment 2 years though)
@DEAR - PLEASE do it!!
