DATEV is a German software provider serving tax advisory, auditing, legal advice, businesses and the public sector. Its portfolio comprises more than two hundred software products and IT services, including cloud applications for accounting and payroll such as DATEV Unternehmen online, the DATEV E-Rechnungsplattform, a marketplace for partner applications and remote support. Many German businesses work with DATEV through their tax advisor, which is why other software, such as Candis, integrates with it. The applications are delivered as cloud software and through DATEV's own data centre.
DATEV eG is a registered cooperative (eingetragene Genossenschaft) headquartered in Nuremberg, Germany, whose members are tax advisors, auditors and lawyers. According to a secondary source, most client data is processed in the data centre in Nuremberg; DATEV's main page itself does not name hosting locations. DATEV is proprietary software, and European organisations that need the exact processing location should obtain it through the data processing agreement.
