Customer Comments

Devon and Cornwall Housing

"Devon and Cornwall HA uses ProVal, Sequel and Catalyst. We have been using some of these applications for over five years. We have always found the training provided by SDS to be relevant and thorough. Once trained, staff find the applications straightforward to use.The SDS after sales service has always been quick to respond and helpful with any queries and problems which we may have. ProVal and Sequel are essential tools in carrying out our housing development programme. Both provide relatively streamlined approaches so that staff can complete quick appraisals and manage projects with minimal internal bureaucracy. I would recommend these applications to other companies."
