PC performance and availability of high quality (laser) printers (in duplex A4/A3) on site made the "in-house" processing of end client data both faster and more flexible than data center processing. Legal The organisation is a registered cooperative. Membership is only open to members of the tax, accountancy and legal professions. Business In 1998 CEO Dieter Kempf led an initiative to add a second leg to its business by entering the legal services market. DATEV's takeover of the Hamburg-based company "MCT" brought the software "Phantasy" in its product portfolio.

Viruses, trojans and keyloggers are quickly detected minimizing any data unwanted infection or manipulation. To complete the protective belt a revers Web radar scan was also introduced into DATEVnet.
