Hi @Amanda Watson
Learning about why customers don't renew is incredibly powerful because what you learn can not only be used in CS but shared with marketing, sales and product.
Essentially, customer interviews provide deep insights that surveys, calls, discussions, emails etc just can't provide.
And hiring an outside provider allows for a degree of separation. This means customers can open up in ways they just don't when the interviews are run in-house.
Happy to talk to you about conducting these types of interviews (It's what my company does ?).
Let me know if you're interested.
P.S. Here's a LinkedIn post about the 25 Customer Churn Factors that impact a customer's decision to churn. These are the reasons why customer interviews are so important -- they help to identify which factors impact your customers the most.
