There are two versions, Jewelry Design Manager, and Jewelry Design
I've used the Jewelry Design Manager, and I liked it well enough. It
was very handy for pricing finished articles and keeping track of
inventory. It also has a nice report section where you can have it
build catalogs, with retail pricing, wholesale pricing, or cost - or
all three simultaneously. You can include pictures with descriptions
of finished pieces for creating a catalog.
What I didn't like is that the program didn't remove anything from
inventory until you showed the item as sold.
It also has a section where vendor details are kept, along with
inventory. There is an accounts receivable where you can build a
customer mailing list, and an invoicing function for sales.
I haven't used the Pro version, but I've heard it has a few more
bells and whistles making the program even more robust.
