    The diploma thesis presents IS MODIS with legacy technologies, into which an interface for the fiscal verification of invoices has been integrated. The statutory requirements for the fiscal verification of invoices are presented. The problem of using said technologies for establishing a TLS session, for calling online services, for digital signature and verification of messages in PowerBuilder 9.03 and 12.5 is presented. IS MODIS is described, its structure and the system's basic operation. The objects which appear in IS MODIS are presented. Two process flow and data flow diagrams for the process of issuing invoices in the initial and final state are shown and explained. All of the necessary modifications to the application and database are mentioned, followed by a description of new objects and their functions. The objects which had to be supplemented or into which specific calls to new functions and objects had to be integrated (either to control functions or to the external program for communication and sending of data to the Financial Administration of the Republic of Slovenia) are listed. A solution for calling an external program, which communicates with ISFU, using command line parameters is presented. In the conclusion a description of the installation of the module into the production environment, a list of problems in the initial stage of operation, and a description of the add-ons requested by clients or the legislator are given, followed by a number of improvements or suggestions for easier maintenance and upgrading of IS MODIS.
