I'm running a number of PPC campaigns for a client. I've set up phone calls and form submissions as conversions, and I'm getting good data from Adwords about those conversions. I'm now looking for a tool to continue tracking the conversion of these leads after they come in - which ones converted into sales and how much each sale was worth. I'm also looking to add some specific data capture like which employee fielded the call.
Any suggestions for a platform that is easy to set up and easy to query? I'm not exactly sure what types of queries we'll be running in the future so I'm looking to capture all the data I can now hoping that I can mess around with it as much as I want in the future.
