questions about uploading my practice documents, sending them to clients and seeing documents clients have filled in

I am a new user to Simple Practice.  I think I uploaded my HIPPA forms but I do not know that my clients are getting them AND I cannot find where and how I access the forms my client has filled in. Please help. I have watched the videos and they do not address these issues.  I am frustrated and running out of time to decide f I want to sign up of not.

I would also like to know how much it is to sign up.  I have a small 6-8 hour a week practice.
