# SalesAgreement - customer - INTERFACE
Version: 2025-04

## Description
A contract between a merchant and a customer to do business. Shopify creates a sales agreement whenever an order is placed, edited, or refunded. A sales agreement has one or more sales records, which provide itemized details about the initial agreement or subsequent changes made to the order. For example, when a customer places an order, Shopify creates the order, generates a sales agreement, and records a sale for each line item purchased in the order. A sale record is specific to a type of order line. Order lines can represent different things such as a purchased product, a tip added by a customer, shipping costs collected at checkout, and more.
