When a New Subscription is Created
A Customer record gets automatically when a new subscription(not linked to a customer record) is created through the hosted page, Chargebee UI, or API.
Info: How Hosted pages work - Here, when your customers subscribe to one of your plans using the checkout page, a corresponding customer and subscription record will be created in Chargebee.
Using the UI/Admin console
To create a new customer go to, Chargebee Dashboard, Customers > Create Customer. To create a subscription for that customer you can use the Create subscription option from the Action panel to the right.
You can use the create customer using the API or create a subscription API to create a subscription along with a customer record.
Here is more information on the checkout page.
