Worked for a SaaS that took in sales data and generated customer surveys. There were a few things I did 1. Create an easy way for support to login as a different user so that they could see what the customer sees. 2. Created a report that figured out how often each customer sends data and noticed when they were 2 standard deviations away from their average data send. We went from customers calling upset that their data is not up to date to us calling them and letting them know that they stopped sending us data.
