While Rho Departments can be used to categorize expenses and card spend based on company departments, projects, vendors, seasons, etc, labels can be used to track revenue in addition to expenses. Labels are also a helpful tool in sub-categorization.
You can only assign one Department to a transaction at a time, however you can assign as many Labels as you would like to one transaction.
First navigate to Reporting > Labels in your Rho dashboard.
Click the + New Label button in the right corner to create a new label.
Select a name and a color for your new label in the pop-up window, then click Save Changes.
