Pastel is an inventory control software package designed to make it easier to manage inventory. According to the Pastel website, the user can create "up to 999 stores," meaning that is the maximum number of groups or categories that the system will support.
Like many software progams designed for business, Pastel is continuously updated and refined. Modifications enable businesses to better track inventory and to more easily reclassify items within the various groups or categories. It also allows users to calculate costs for items, including unit and average costs, which can vary depending upon any number of factors, including costs to purchase and store (the latter being particularly important if the inventory involves perishable items) inventory, and cost variations associated with intervening variables like global supplies of a particular item and costs associated with transportation.
