I use Trac for all those things with the following plugins: * Time tracking: http://trac-hacks.org/wiki/TimingAndEstimationPlugin * Planning/reporting: simple trac reports + wiki dashboard. * Customer service, we have a separate trac instance with Intertrac set up between so you can link tickets. * VCS integration: works with hg and svn fine Also costs zero and upgrades flawlessly.
