The video doesn't start - I know it could be a line problem, but it should me blazingly fast everywhere, since that's what you're using to sell your product. And once started, it's tiny!

Also, excluding the video there aren't any screenshot around, and the "Tour" is just a list with tiny thumbnails.

Excluding those things, however, I think that everything else is well done: it clearly states the price (maybe, add a high-level offer with an high price tag) and explains pretty well some advantages. Also, the try button is everywhere so it's ok. :)

Why don't you offer a basic free-forever account with like: 1 user, 1 project, 1 invoice/month, etc. Something like this. I think it would be perceived really better than a 30-days test (that will still exists!).
