There are three ways in which languages are set for customer

Chargebee will:

Allow you to set a language for your customer or
Allow your customers to choose a language for themselves or
Display the details in a different language automatically

Allow you to set a language for your customer

In the Chargebee user interface, you can select the language while creating the customer or update the language setting for an existing customer.

In Leap UI - Language field in customer details page

In Classic UI - Locale field in customer details page

Note:

Once a customer’s language is set, it cannot be removed. However, you can update it to a different language at any time.

Allow your customers to choose a language for themselves

If you have enabled the Customer Portal, your customers can login and set the language themselves. They can do this by navigating to the Edit Account Details page in the Customer Portal and selecting a language from the menu there. Chargebee will display a list of languages in the customer portal. Your customers can select a language from the list.
