@Thomas Blain both Ed and Daniel have given you good answers.
I'd like to add that it's really concerning to hear you have a high churn rate. It means that something (or likely many things) is taking your happy customers and making them unhappy.
I would suggest hopping on a call with some of your churned customers to find out why they churned.
Even a 15 minute call can elicit some very useful info and determine the product and service issues (like onboarding or support) that are causing the majority of your churn.
If you want some assistance with creating the right questions to ask, let me know and we can hop on a call.
