The sales agreement is the document that obligates the client to pay for the purchase of merchandise in an interior design project. This legal document outlines the terms and conditions of the sale, including the obligations of both the buyer and the seller. It specifies the type of merchandise being purchased, the total amount due, payment terms, delivery details, and any other necessary conditions related to the transaction. By signing the sales agreement, the client accepts these terms, thus creating a binding obligation to pay.

Other documents like a purchase order may initiate the order but do not constitute a binding agreement on payment in the same way that a sales agreement does. A freight bill primarily details shipping costs and logistics, while an acknowledgment serves more as confirmation of receipt rather than a payment obligation. Therefore, it is the sales agreement that plays the critical role in formalizing the financial commitment in an interior design transaction.
