What is Category Tree?
Category tree is a structure of your inventory with all the products, organised in such a way to get a complex and meaningful report based on your need. In amazon, all the products are treated as individual ASIN / SKU and it is difficult to get detailed sales behaviour or report of a product with different designs and collections.
So with KwickMetrics, you can easily convert all the designs and collections of the product as a single category and get the collective reports and metrics.
