In the cash sales process, which document type produces the customer invoice?

In the cash sales process within SAP S/4HANA, the document type responsible for producing the customer invoice is the billing document. This document is created after goods are delivered to the customer and captures the financial transaction for the sale, detailing the amount the customer is required to pay. It is essential for revenue recognition and accounting purposes.

A sales order is primarily used to record the intention to sell products and does not directly create an invoice. Similarly, a delivery note is a document that verifies the delivery of goods to a customer but does not encompass the financial aspects of the transaction. A credit memo request deals with adjustments related to sales, such as returns or discounts, and does not produce a straightforward customer invoice.

Thus, the correct understanding in this context is that the billing document specifically fulfills the role of generating the customer invoice in the cash sales process, aligning with financial and sales workflows.
