generally you would add the custom fields to the customer object, and those are inherited to the invoice automatically

the customer object has also custom_fields?

[urban saddle]

that's really the only option here. Certain updates to subscriptions result in immediate invoices that you can't update before they are finalised

[urban saddle]

yes, https://stripe.com/docs/api/customers/object#customer_object-invoice_settings-custom_fields
