I think for a team work effectively you need differentt tools - Slack for instant communication, Basecamp for tracking project status, Trello for organising work flow and etc. It is impossible to have a tool that fits all your needs.
Keeping an eye on parse-hosting.com they have the most details about their plans and pricing so far. Do you have some more information? The landing is not informative at all. Would be interested to know what are you doing to offer.
