Kältepol, an Austrian agency, has since 1950 been planning, designing and building equipment for restaurants and refrigeration engineering. In order to manage and administer their work processes for the entire agency, they use the 4D-based solution called "Die Firma" ("the company") from Austrian developer WIRA Software. The system handles accounts, on-site repair handling, barcode systems, payroll statements, archiving, and it even connects the bookkeeping system to the Austrian tax system – all without a single day of downtime since its implementation in 1992.
