Customer Churn Rate, and Ecommerce Analysis Stripe

Looking for the most simple easy way to do some Customer Churn Analysis. Are there any plugins, or tools to help do some Analysis on Customer Churn Rates that work specifically well with squarespace?   Or is just a manual export to Excel the best path.  

Here are a few tools I found:

Anyone have any experience with these or others? 

Thanks for sharing the tools needed to analyze customer churn rates in Squarespace.

I guess nobody does this type of analysis.
