Taj has built a fantastic app, especially useful for small businesses like myself who sell a bunch of designs on a range of blank apparel - it helps me keep stock levels accurate across a range of products that share the same blank stock. I searched high and low for an app to achieve this, and there aren't many options out there. Highly recommend this app.
