While the specifics of a point of sale system will vary somewhat from one situation to another, the final outcome is always the same.

(Jane Harmon, 2010), Point of sales (POS) software is a type of software that retail store use to calculate their sales and operate the cash drawer; it is a computerized cash drawer. Point of sales add up the sales total and calculate the change. When customer buy items from retail store, point of sales will minus or debit the amount of item sold in the inventory system. At minimum, POS should be able to handle sales and manage your inventory database.

Point of sales system is mostly found in supermarket. The point of sales system consists of the checkout counter, bar code scanner, and the cash register. Every time when an item is scanned, the system count the cost; till all the items selected by the customer are scanned, the system will calculate the total cost of all item that customer would like to purchase. Customer will then pay amount money, using either credit card or cash. If customer pays by cash, the point of sales system will allow the cashier to input the amount of money that customer pay and calculate the balance that should be returned to the customer.
