Which of the following statements is true about invoices and sales orders?

Invoices can exist independently of sales orders, making this statement true. In a business context, sales orders typically represent the formal acknowledgment of a customer’s intention to purchase goods or services, setting terms for the transaction. However, invoicing can occur in various scenarios where either a sales order isn't present or isn't required. For instance, businesses may issue invoices for services rendered that didn't stem from a formal sales order or in cases of immediate sales where products are sold directly to customers without a prior order being established.

This flexibility is crucial for businesses that operate in various domains, allowing them to manage their cash flow and revenue recognition effectively. Understanding that invoices can be generated outside the confines of a sales order aids users in effectively using NetSuite's invoicing and sales order functionalities, aligning with the diverse operational processes that companies might follow.
