É fácil e ajuda a manter todos os seus projetos em um só lugar.

I am able to remember tasks easily thanks to the tagging feature. I get emailed every time someone assigns a task to me.

ActiveCollab is about the only high quality workflow product that doesn't charge per user. It has a clean no-nonsense UI that is easy to stare at and use. Project, to-do's, and team management are intuitive and flexible enough to mend to all types of products and team organizations. It has customer facing views/logins, a time-tracking app, and an ever increasing amount of other integrations like Slack or Quickbooks. It is the best bang for the buck as far as workflows and project management is concerned and if you're willing to deal with a few of its fundamental quirks, you can shed a number of other apps you may be using.
