Which Sales Order transaction form can generate a Cash Sale upon billing?

The correct answer is that the Standard Sales Order transaction form can generate a Cash Sale upon billing because this transaction type is designed to directly facilitate the sales process, allowing for immediate processing of orders and payments. When a standard sales order is created, it acts as an agreement to sell goods or services that are delivered immediately, and the billing process can subsequently convert this order into a Cash Sale, reflecting that the payment has been received upfront.

In contrast, other forms listed serve different purposes. The Standard Sales Order - Invoice generates an invoice rather than a direct cash sale, meaning the payment may not be received upfront and is instead invoiced to the customer for later payment. The Standard Sales Order - Deposit involves receiving a deposit rather than the total cash sale, indicating that the final transaction is not yet completed. The Standard Sales Order - Progress Billing is specific to projects where billing is done in stages based on the completion of certain milestones, thus not resulting in an immediate cash sale. These distinctions explain why the Standard Sales Order is uniquely capable of generating a Cash Sale.
