What is the commercial document issued by a buyer to a seller that indicates types, quantities, prices, and terms?

A Purchase Order is a key commercial document in supply chain transactions, serving as a formal request from a buyer to a seller. It outlines crucial details such as the types of products or services being ordered, their quantities, pricing, and any specific terms and conditions associated with the transaction.

This document acts as a legally binding agreement once it is accepted by the seller, ensuring that both parties are aware of their obligations. The clarity provided by a Purchase Order helps prevent misunderstandings and disputes regarding what has been agreed upon. It streamlines the procurement process, enabling efficient order fulfillment and inventory management.

In contrast, other options pertain to different aspects of the supply chain or logistics. For example, a Bill of Lading is primarily used as a transportation document acknowledging the receipt of goods for shipment, rather than detailing an order from buyer to seller. Collaborative Supplier Planning refers to the strategic approach of working with suppliers to optimize performance but does not involve a specific transactional request. A Delivery Schedule addresses the timing and logistics of when goods will be delivered rather than the specifics of the order itself. Thus, the Purchase Order is the most appropriate choice for the described function in the question.
