Summary
In Chargebee, when consolidated invoicing is enabled, the subscription renewals and unbilled charges for a customer are consolidated into a single invoice. Any 1st invoice raised when a new subscription is created/activated (including those activating after a trial period and those set to start at a future date) is always invoiced separately unless added to unbilled charges.
To avoid a separate 1st invoice, please write to support@chargebee.com to enable the 'Consolidation during subscription activation' feature for your site.
