Not even sure if this exists and I've tried a bunch of inventory apps already and maybe I just don't know how to use them correctly. But here is my issues. I sell fabric. I sell in yard cuts and fat half cuts. A fat half is essentially a half yard just cut the opposite direction (horizontally instead of vertically) than a half yard. My issues is that I buy the fabric in bolts. So if I buy a 10 yard bolt of fabric and sell a yard I now have 9 yards left in inventory. If I then sell a fat half I now have 8.5 yards left in stock. Is there any way to track this?
