(h2>POINT OF SALE
The point of sale (POS) is the time and place where a retail transaction is completed. It is the point at which a customer makes a payment to the merchant in exchange for goods or after provision of a service. At the point of sale, the merchant would prepare an invoice for the customer (which may be a cash register printout) or otherwise calculate the amount owed by the customer and provide options for the customer to make payment. After receiving payment, the merchant will also normally issue a receipt for the transaction, though increasingly a receipt is being dispensed with.
The POS in various retail situations would use customized hardware and software tailored to their particular requirements. Retailers may utilize weighing scales, scanners, electronic and manual cash registers, EFTPOS terminals, touch screens and a variety of other hardware and software available. For example, a grocery or candy store may use a scale at the point of sale, while a bar and restaurant may use software to customize the item or service sold when a customer has a meal or drink request.
The point of sale is often referred to as the point of service because it is not just a point of sale but also a point of return or customer order. Additionally, today POS software may include additional features to cater for different functionality, such as inventory management, CRM, financials, warehousing, etc.
