Ordering refers to the act of adding goods or services to the shopping cart and confirming the purchase during shopping or trading. On the e-commerce platform, placing an order usually includes adding the goods to the shopping cart, filling in the delivery information, selecting the payment method, and finally completing the payment. Ordering online may involve the process of selecting goods, informing sales personnel of their purchase intention and paying for the goods. In addition, in financial transactions, such as futures trading, placing an order means that the customer sends a trading instruction to the business personnel of the brokerage company, specifying the type, quantity, price and other information of the contract to be bought and sold. Specifically, there are many ways to place an order. For example, on the e-commerce platform, you can click the corresponding button to complete the order, offline stores can verbally inform the sales staff of the purchase intention, and in financial transactions, you can issue trading instructions by writing, telephone or other prescribed means. After placing an order, the merchant or brokerage company will handle it according to the customer's order information, such as preparing goods, delivering goods and executing transactions.
