A reservation system is a software tool that helps businesses manage bookings for services or products. Commonly used in industries like hospitality, travel, and entertainment, these systems allow customers to reserve items such as hotel rooms, flights, or event tickets online. They streamline the booking process, reduce errors, and improve customer satisfaction. These systems often include features like real-time availability, payment processing, and customer notifications. By automating the reservation process, businesses can save time and resources while providing a better experience for their customers. Examples of popular reservation systems include Booking.com, Airbnb, and OpenTable.
