Jumbo book store is a company based in Thailand. It has three book stores and a warehouse next to one of the book shops. The store manager, Amiki Sukhon , finds it very difficult to track sales because he uses handwritten sales reports that employees prepare every day. The driver takes the reports and delivers them to the main office. Every day it takes 5 to 6 hours to compile data about the sales. Based on these sales report, Amiki writes purchase orders for new books , sales figures for the owner and customer information for the marketing department.
