I did translate this now but it looks like you don't have this plugin.
You do have a DynaReg for Stock Quantities (this allows you to put in Dozen or six-pack in the stockinformation Units tab with a Qty)
This Qty can be used to reorder but you still sell it one a piece.
Or you can sell 1 dozen and get the price X 12.
This plugin is for quick stock counting.
Did you mean to buy this plugin?
