What's the best tool for agency / client collaboration?

I am helping a friend with a new agency, and was looking for the best tool for collaborate with their clients. Here I was thinking very obvious features such as: client can create new tasks, agency can give price estimate, chat inside projects, message board on specific tasks, a review board (parts accepted / not accepted) on a project. This tool must exist but I just cannot find it :)
