Customization to show roll-stock inventory graphically, showing cut lengths, remnants, roll lengths.

My company sells and fabricates conveyor belt.  We buy multiple large rolls of material and cut smaller pieces from the large rolls.  We currently have no way to identify the actual shape and size of a roll once we've cut into it, unless we visually look at it first hand.  We also have no way to tell how many full rolls are in stock for a single item.  I am searching for a developer to see if there is a way to graphically "map out" cuts for partial rolls as they are sold, so we can see what is in stock without having to physically measure.  I am thinking that there may be an add-on product developed for the steel industry, or carpet sales, which would be similar in how product is sold.
