Verified step by step guidance

1. Understand the purpose of a purchase order: A purchase order is a document issued by a buyer to a seller, indicating the items, quantities, and agreed prices for products or services the buyer intends to purchase. It serves as a formal request and a legal offer to buy.
2. Review the typical components of a purchase order: Common elements include payment terms (e.g., net 30 days), quantity of goods ordered, description of items, shipping details, and the agreed price. These details ensure clarity and prevent disputes between the buyer and seller.
3. Analyze the role of an invoice number: An invoice number is a unique identifier assigned to a seller's invoice, which is issued after the purchase order is accepted and the goods or services are delivered. It is not part of the purchase order itself, as it pertains to the seller's documentation.
4. Compare the listed options with the components of a purchase order: Payment terms, quantity of goods ordered, and description of items are standard elements of a purchase order. However, the invoice number is not included because it is part of the seller's invoicing process.
5. Conclude that the correct answer is 'Invoice number,' as it is not typically included in a purchase order but is instead part of the seller's post-sale documentation.
