Chargebee provides the option to have a custom domain in the hosted pages and customer portal URL. Also known as white labeling, this lets you have your brand on the hosted pages' URLs, instead of Chargebee's. This ensures a consistent customer experience.
Say, the URL of your current checkout page reads yourcompany.chargebee.com.
With the Custom Domain feature enabled, you can have a URL that reads billing.yourcompany.com.
If you'd like this feature enabled for your site, please write to email@example.com
