The team at Nulinnovation are very professional, knowledgeable about their product range as well as having great communication skills which makes them easy to work with! They helped us understand our business needs better than we could have done ourselves so that they can develop solutions for those specific problems along side any new ideas or features requested by clients / customers - this has been really helpful when it comes time to implement software enhancements such as reporting functions etc.. Nothing specifically but I would say maybe more detailed information regarding what exactly happens during an upgrade process? We use null innovation's data analytics platform called 'data lake' where all your unstructured/ semi- structured customer data resides allowing you access via web portal using standard SQL queries rather then needing bespoke ETL tools like SSIS etc...
