Chargebee gives you the option to customise your emails, invoices, credit notes, checkout pages, and your customers' self-serve portal.
This will help you align Chargebee with your branding.
To configure your branding in Chargebee app, navigate to Settings > Configure Emails and Invoices > Customize Styles and you'll be given the options to add logo, icon and choose a color from the palette.
Next, pick a theme color which will be used for buttons or text.
Upon completion, you'll get to see a preview of the email and the invoice.
