Hi Tuk66,
if i update the stock avaiable i don't know when an item is sold, how many items and in what kind of color, how much i have sold this month and what kind of manufacturer is my best seller.
All this information are vital for our business. if i will need to do by hand, mixing information from the site and a lot of paper that i need to compile by hand, there is an high chance of error and a delay of this analysis
