I have the Jewelry Designer Manager Pro also......it's GREAT! Once I got through the chore of inputting my inventory, it has been a lifesaver when it comes time to figure costs on a design. I just keep track of what I use in a piece on a post it note, then I log in the parts used....and the cost is figured for me.....and the markups.
I definitely recommend this software to anyone who wants to be more accurate with their pricing. ( I know I was always terrible at 'guessing' the costs of a made piece!) It's well worth the initial cost of the program. Evalie
