This is a significant issue for us. We can't see stock and sales at a grouped product level, only at SKU level. In our case, apparel, SKU = size. Most of our reporting should be at one level up ie style/colour ie WooCommerce's product level. We want to see instantly sum/detail at any level of product hierarchy. Our product hierarchy is Brand/Category/Style/Colour/Size. We are currently using Attributes for Brand & Colour, and Variations for Size. Should we set up our product differently? I am not able to upload images, do I need to start another thread or can I email you? By the way, I have run inventory planning teams for 15 years for Nike, Carhartt, VF Corp etc. Happy to help!
