How do (POS) or Point of Sale in Sales Inventory of a Bookstore works?what are the process?

Answer 1

It's all computerised so it's kinda hard to explain. Basically, when you use POS software, it captures a sale when you scan the barcode on the pricetag of the book. So the sale amount is captured immediately. At the end of her shift, the cashier can read from the printout how much cash she should have in her till and check for accuracy.
At the same time, since the sales module is integrated with the Inventory module, the title of the book is captured as sold 1 copy. The cost of the book should also be deducted from the inventory balance. On the day of the stockcount, you will need to compare the inventory per the printout to the books you actually have on the shelves. Differences can be due to wrong coding at time of purchase or customers coming in to exchange books and the info is not updated, pilferage, etc.
