Software and Services for Catholic and Orthodox Organizations

Parish Data System (PDS) has been the leading developer of Catholic and Orthodox Church software solutions since 1978, meeting the needs of more than 9000 parishes, schools, and dioceses worldwide. We attribute our success to the fact that we know how parishes and dioceses work because PDS was created for the Catholic Church by a Catholic priest.
