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. When a customer makes a purchase, the POS system calculates the total amount, processes payments, and generates receipts. In addition to handling sales, a POS system can also track inventory, manage customer data, and provide sales reports. This helps businesses streamline operations and make informed decisions. Many modern POS systems are cloud-based, allowing for remote access and real-time updates, enhancing efficiency for retailers and restaurants alike.
