What is typically shown on an invoice?

An invoice primarily serves as a financial document that outlines the details of a transaction between a buyer and a seller. It typically includes descriptions of the products sold, such as the name, quantity, and price of each item. This information is crucial for both parties to ensure clarity regarding what has been purchased, the cost involved, and helps in maintaining accurate financial records.

While other elements may be relevant in different contexts, they do not form the central focus of an invoice. Customer feedback is more suitable for review and improvement purposes rather than transactional documentation. Project timelines may be relevant in contract agreements but are not typically included in a standard invoice. Logistics of delivery, while important for order fulfillment, do not constitute the main purpose of the invoice itself, which is to detail the sales transaction. Hence, the inclusion of product descriptions is what makes option B the correct choice.
