We'd like to be able to customise the "billed to" address using the same templating method the Settings -> Configure Emails & Invoices -> Customize Invoice & Credit Note -> Organization Address Format -> Custom option uses.
In the Netherlands they have the zipcode before the city, and we want to have the company name before the customer contact name.
Unfortunately, we do not have the option to customize the billing address of the end customers. They appear in the order of the billing address fields in Chargebee. We have this option as a feature enhancement and I've tagged your request to step up its priority.
