An invoice is a summary of all charges incurred by that account during the billing period. If the account is the Invoicer, then the invoice includes all charges incurred by the account and its associated accounts. The following line items are associated with an invoice:
When an invoice is first created, it is placed in "draft" state. Once the bill run with the run invoice option is complete and the invoice is finalized, it moves to the "Posted" state. When the invoice PDF is created, it moves to a “Rendered” state, and when the invoice is delivered, it will move to a final state of “Delivered”. From there, an invoice can only be "voided". An administrator voids an invoice when they wish to cancel the invoice. A new invoice can optionally be issued once the old invoice has been voided (cancelled).
The account that receives the invoice is called an invoicer. Only an account that is configured as an invoicer can receive an invoice. The usage and subscription invoicers specified must be the same, splitting invoices is not currently supported. Any account can be specified as a subscription or a usage invoicer, the account does not need to reside in the same account hierarchy (e.g. a parent account).
The invoicer's bill group and bill day will be observed when billing. This constraint is enforced through the user interface.
