A point-of-sale (POS) system is a combination of hardware and software that allows businesses to complete sales transactions. It typically includes a computer or tablet, a cash register, a barcode scanner, and a payment processing terminal. POS systems help track sales, manage inventory, and generate reports, making them essential for retail and hospitality businesses. In addition to processing payments, modern POS systems often integrate with other business tools, such as inventory management and customer relationship management (CRM) software. This integration helps streamline operations and improve customer service by providing valuable insights into sales trends and customer preferences.
