General information
Hungarian National Tax and Customs Administration (NAV) continuously provides an opportunity for domestic and foreign software developers to participate in the development of the Online Invoice System (OnlineSzamla). The professional dialogue aims to develop the Hungarian Online Invoice System according to the needs of the users, following the suggestions of the developers of the invoicing software. Hungarian NAV is the first agency on GitHub to provide software developers with the opportunity to work together to shape the future of the data delivery systems. In addition, they can have a direct dialogue with the system developers and experts in the online forums. Based on the feedback received by Hungarian NAV, the Online Invoice System (OnlineSzamla) has already been expanded with several functions and possibilities. A new direction of the system’s services is the support of electronic invoicing. Hungarian NAV also assessed taxpayer's and developer needs, which determined the further development of the service. The support of electronic invoicing in the Online Invoicing system is not based on a legal obligation but has evolved from market needs and proposals received by Hungarian NAV. In addition to future developments, the continuous maintenance of the system and the strengthening of existing functions are also a high priority. The Online Invoice System is constantly adapting to the needs of external use. Hungarian NAV pays special attention to the continuous improvement and updating of the system and provides the possibility of data queries and its continuous expansion to users in addition to legal compliance.
