Reservatic is a unique online reservation system designed for mutually effective service ordering by a customer. The aim consists in eliminating the customer's waiting for the service ordered and in offering the service provider a system for a more efficient use of working time and for the limitation of time loss. Both parties book, cancel or change reservations daily. A challenging agenda is related to this and it causes both time and financial problems. The Reservatic application focuses on this very problem and it offers a simple and elegant solution based on the use of both online and mobile applications.
