Which of the following is NOT included in an invoice?

In the context of invoicing, the correct choice identifies that the delivery date is typically not a standard element included on an invoice. Invoices primarily focus on billing-related information, such as whom the invoice is addressed to, the payer's details, and customer identification. This includes the invoice recipient (INRC), the payer (PYNO), and customer information (CUNO), which clearly establish the transaction's parties and their associated accounts.

While the delivery date may be significant for tracking shipments or for internal records, it is not a necessary component of the invoice itself. An invoice serves to request payment for goods or services rendered, and its critical sections pertain more directly to the financial aspects rather than logistical details like delivery dates. The absence of the delivery date from the invoice aligns with standard practices focused on payment terms and invoicing protocol.
