A Point-of-Sale System (POS) is a combination of hardware and software that allows businesses to complete sales transactions. It typically includes a cash register, a computer or tablet, and a payment processing system. 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 customer relationship management (CRM) software and e-commerce platforms. They support various payment methods, including credit cards, mobile payments, and digital wallets. This versatility makes POS systems essential for retail stores, restaurants, and service providers.
