Software for the administration of church organizations

With ISIDOR, you create a central and reliable database for your administrative work. Information on people, responsibilities and organizational data is maintained in one place and is available wherever it is needed – such as on websites or in organizational charts. This forms a stable basis for day-to-day work in dioceses, regional churches and other church institutions.

  • Provide up-to-date information

  • Avoid duplicate data maintenance

  • Noticeably relieve employees

Manage people, responsibilities and structures in one place.

We speak church

ISIDOR has been supporting church organizations in their daily administrative work since 2009. Our software is developed in close cooperation with the user community – for a solution that is really needed in everyday church life.

ISIDOR is backed by many years of experience in the Catholic and Protestant churches. With more than 25 years of professional experience and voluntary work, we have first-hand knowledge of the processes and requirements of church institutions.

What our customers say

Martin Faatz

Deacon Dr. Martin Faatz
Head of the Central Tasks Department in the Episcopal Ordinariate of Würzburg

“ISIDOR knows church and understands church. The database has been developed for church structures from the very beginning.

In the beginning, we contributed our expertise as the Diocese of Würzburg. Today, a growing community is driving development forward. The shoe simply fits. We benefit from this every day, from the central administration to the parish offices.”

Jonas Wangen

Jonas Wangen
Evangelical Church in Germany (EKD), IT Service

“Isidor understands the structure of the church better than any other provider on the market. Offices, bodies, committees, appointments and much more can be found in this structural database.

For the EKD, it is an indispensable tool for central address and distribution management.”

Tina Huppmann

Tina Huppmann
Diocese of Fulda, Chancery Staff Department

“ISIDOR has been in use for over 10 years and is an indispensable tool for the Diocese of Fulda.

Central address and information database, digital personnel schematism, mapping of the diocese structure in curia and territory and much more – our users benefit daily from ISIDOR as a central data hub.

Additional interfaces enable data protection-compliant and automatic data transfer to other systems and save resources thanks to centrally controlled data maintenance.”
