Startup Idea: Craft Inventory & Pricing Management Application

Startup idea to develop a software tool that helps small artists, particularly jewelry makers selling at craft shows, in tracking their supplies cost, managing inventory, and calculating the cost of production for efficient pricing

I sell jewelry at craft shows. I would love software that tracked my supplies and their cost. Then when fighting out my pricing I could select the materials used to come up with a cost to make to base price on. This could then connect to inventory for my supplies and product. I haven't because it seems too specific to small artists.
