What this operation supports in Chargebee
Creates a new customer record, accepting basic profile details like name, email, and billing address, before any subscription is attached to them.
Implementation details
A customer can exist in Chargebee with no active subscription at all -- creating the customer and creating a subscription for them are separate steps, so this call alone doesn't start any billing.
Operational considerations
Because billing address and tax details set here affect how later invoices calculate tax, getting this information right at creation time avoids having to correct already-generated invoices afterward, which is a more involved fix once billing has already run.
