Modern technology has reached an enviable level in all segments, abounds in numerous innovations that have been implemented in daily life and the business of modern companies. Through information technology in business, companies gain significant competitive advantages and achieve enviable results. The implementation of information systems, as part of information technology, is gaining increasing application in all segments, including the hotel industry. Hotel business is also adapting to the trend of business informatization, so the introduction of Internet reservation systems is just one of the ways to apply it. Namely, the needs of the modern population that make up potential hotel guests have changed greatly and they receive a large amount of information through the Internet before making a decision. Since the subject of the sale is a "service", it should be made as accessible as possible. Online booking actually brings mutual benefits to both the hotel and the guest. For the guest, this means an easier and simpler approach to booking accommodation and greater availability of information, and for the hotel it means in the first place relieving staff, flexibility and ultimately increasing efficiency and productivity and global availability of hotels in the tourism market. In addition to reservation systems within the telecommunications services provided in hotels, there is a tendency to increasingly implement smart technology solutions as part of the hotel offer, which raise the quality of service. Some of them are interactive television, PayTV, internet, etc.
