This is the Product Tracker Sheet discussed in the latest episode of Uncut! Your’s for free. Some of the cells are locked due to automatic calculations. All you need to do is to plug in the data required and you will be able to analyse it very easy from the start! I recommend doing these sheets every month with your new products or categories to see what working well over time!
Granted, If you have a fresh store without any customers like me, it might take some time in order to get some raw input (like sales) consider running the product test for a longer time.
