The document that provides complete information about the goods sold is the invoice.

An invoice is a detailed statement provided by the seller to the buyer containing important information regarding the sale of goods. Here’s why it is deemed so comprehensive:

• Itemized List: It includes an itemized list of the goods sold, along with descriptions, quantities, and unit prices.
• Total Amount: It shows the total amount payable by the buyer, including applicable taxes and discounts.
• Terms of Sale: It outlines the terms and conditions of the sale, such as payment due date and methods of payment.
• Identification Details: It contains essential information like the invoice number and date, which helps in tracking and reference.
• Seller and Buyer Information: It includes the names, addresses, and contact details of both the seller and the buyer.

In contrast, the order form is a document generated by the buyer to request goods but doesn't contain the details of the actual sale. A delivery note accompanies goods to confirm delivery but lacks pricing and terms. Lastly, a bill of exchange is a financial document used for payment agreements, not for detailing goods sold.

Therefore, the invoice is the key document providing complete information about the goods sold.
