However, there is also a large number of Member States (Czech Republic, Germany, Hungary, Ireland, Italy, Lithuania, Latvia, Malta, Portugal, Sweden, Slovakia, Cyprus and the Netherlands) who use only the Internal Market Information System for the administrative cooperation because it is considered more convenient or in the absence of any applicable bilateral agreements.
Siiski on palju ka selliseid liikmesriike (Iirimaa, Itaalia, Küpros, Leedu, Läti, Madalmaad, Malta, Portugal, Rootsi, Saksamaa, Slovakkia, Tšehhi Vabariik ja Ungari), kus kasutatakse halduskoostöös ainult siseturu infosüsteemi, sest seda peetakse mugavamaks või kohaldatavad kahepoolsed kokkulepped puuduvad.
