Looks good, needs some polishing. pixelised logos, typing errors in the billing plans. Otherwise the rest looks neat so far. I have a few concerns regarding the safety of sharing my company data on the website for example so something should be covering that. And also I would instantly pay for this service if it had a Ganttchart (with drag and drop) and WBS feature
