What does an invoice typically describe?

An invoice is a crucial business document that serves as a record of a transaction between a buyer and a seller. It provides detailed information regarding the goods or services that have been sold, including descriptions of the items, the quantities delivered, and the respective prices. This information not only helps the buyer understand what they are being charged for but also assists in proper accounting and record-keeping on both sides of the transaction.

When a buyer receives an invoice, they expect it to outline what they are being billed for, which is primarily the items or services provided and their costs. This ensures clarity and allows for prompt payment processing. The other options focus on aspects that do not accurately represent the primary purpose of an invoice. For instance, pending services, employee work hours, and annual financial reports serve different functions within business operational contexts and do not encapsulate the essence of an invoice. Therefore, option B accurately reflects the primary purpose and contents of an invoice.
