On nexxcite, the customer portal is a workspace of its own that carries your brand: its own colour scheme, set separately for light and dark, your logo in both variants, its own home page and its own navigation with “My requests”, “New request”, “Documents” and “Help”.
If you have several customer groups or brands, each gets its own look and its own service catalogue. Where the colour scheme isn't enough, you can add your own styling and script files per role.
You set this up in the editor, or AI can take it over if you wish: the brief “light colour scheme in our brand colours, our logo, customers see only their own requests” results in four changes in a draft. They apply only to the customer role and take effect only once you approve them.
