Excellent customer support. They have all the most used data sources available. Not sure if the data from multiple sources can be linked in one report.
I use Report Pundit to create some custom reports. I was not able to find the fields I needed to create the report and contacted their live chat. They created my custom report for me with assistance from me on the fields I needed and were extremely prompt and helpful.
Great help from Dominic today. He made some perfect custom fields for me. I would like to be able to make custom fields too and am requesting that you make that option available for us with online tutorials.
