A Point of Sale (POS) system is a combination of hardware and software that allows businesses to complete sales transactions. It typically includes a cash register, a computer, and a payment processing device. POS systems help track sales, manage inventory, and generate reports, making it easier for businesses to operate efficiently. Modern POS systems can also integrate with other business tools, such as inventory management and customer relationship management (CRM) software. They can accept various payment methods, including credit cards, mobile payments, and cash. This versatility makes POS systems essential for retail stores, restaurants, and other service-oriented businesses.
