You can fully customize the client experience so that they see your firm logo and color schemes when using Taxaroo.
To get started, select Settings > Site Branding:
Here you can add your firm's logo (Step 1), and then enter hex color values for other parts of the client page (Steps 2-4).
Not sure which colors to use? Use a site like this to find colors that look great!
Once you save changes, your clients will now see your logo and colors when they sign in.
Note that the site branding only applies to your client's view, and won't update your dashboard colors.
