Teams / Multiple Users

Hi, I'm new to the app so perhaps this is possible within the app already but I'm wondering about a teams / multiple users feature. Multiple team members could log into the app and see the same information. There would need to be a way to show who completed what hours on a project but this would be a very useful tool for my team.
Basically in each project we take on we need to be able to see what hours have been completed and by who so that we are not going over the allotted budget and number of hours agreed upon by the client.
