If you're looking to see new clients or customers and when they've been added or signed up, head to your Customers List. Once there, look for the 'Date Created' column.
Click the 'Date Created' column twice to sort by newest to oldest. Then, you'll see the list of your customers and can view who's signed up on which date and how many new customers you have!
