Which document would include terms of sale and delivery dates?

A purchase order is a formal document issued by a buyer to a seller, indicating the details of a transaction. It specifically outlines the terms of sale, including the types and quantities of products or services being ordered, as well as the delivery dates and any applicable prices. This document serves as a legally binding agreement between the buyer and seller, ensuring both parties are aligned on the purchase conditions.

On the other hand, an invoice is a request for payment from the seller to the buyer after goods or services have been delivered, without necessarily detailing delivery terms. A response to a Request for Quotation (RFQ) is focused on providing pricing and terms for a potential sale, but does not serve as an order confirmation or stipulate delivery dates. A catalog presents a list of products or services available for purchase but does not include specific terms related to individual transactions. Thus, the purchase order is the most appropriate document for specifically outlining terms of sale and delivery dates.
