A Point of Sale System (POS) is a combination of hardware and software that helps businesses process sales transactions. It typically includes a cash register, a computer or tablet, and a payment processing device. When a customer makes a purchase, the POS system calculates the total amount, processes payments, and generates receipts, making the checkout process quick and efficient. In addition to handling sales, modern POS systems often come with features like inventory management, sales reporting, and customer relationship management. This allows businesses to track their stock levels, analyze sales trends, and improve customer service, ultimately enhancing overall operations.
