What describes a Standard Sales Order that becomes an invoice upon billing?

A Standard Sales Order (SO) is the initial document created to initiate a sale in the system. When the Standard Sales Order becomes an invoice upon billing, it means that the sale has been officially processed, and payment is expected from the customer.

In this context, option B accurately reflects this transition because it specifically indicates a Standard Sales Order that leads directly to an invoice. This ensures that the order is completed, payment is recorded, and all relevant transaction details—such as item descriptions, quantities, prices, and taxes—are documented on an invoice format, which is essential for accounts receivable processes and financial reporting.

Other options might not align with this flow. For example, a cash sale implies immediate payment and does not necessarily transition from a sales order to an invoice; instead, it typically skips the invoice stage. Progress billing involves billing in stages, which is not the same as a straightforward sales order that leads directly to a single invoice. An open invoice suggests that the invoice exists but might not be related directly to the concept of a standard sales order transitioning into an invoice for a complete sale. Therefore, the description of option B as a Standard Sales Order that becomes an invoice upon billing accurately captures the essence of this important transaction process.
