From the very beginning, we strive to focus on building Monograph for the small to mid-size design practices. We know that when you are small, every principal and team member has to wear many hats and bill at multiple rates. This is the core reason why we separated "Roles" (billable rates) from a person.
This way, each person has the ability to bill at multiple rates.
By default, we've pre-populated your Monograph Dashboard with default roles, but you can easily create, remove, and edit custom roles in the settings/team tab.
