Ministry of tourism is using a new system from season 2023, called “E-Turist” in Serbia, all tour operator and sub-agents are obligated to register their sales to issue travel guarantee. It is similar to old system UOS which worked between 2018-2023. As we integrated to prior UOS, Onesystem is integrated to E-Turist, therefore our users do not have to enter manually reservations. Our user may issue travel guarantee and print it immediately from their system immediately.
