Nice start, but not really workable except for the most basic of freelance businesses
Moxie is better than most offerings of its type, but it has some shortcomings that I found to be hard to manage. There is no way to track document versions well. E-mail linking was not easy at all and I had to delete my connection to Google more than once and re-add before it would work. You need to add a token to every ad hoc email in order to insert your email signature, unless you only use email templates. The interface is very old fashioned looking. Just lots of little things that make it a time waster for me.
