At the beginning, we will carry out detailed communication with customers, and confirm the products required by customers according to their needs. At the same time, we can send samples to customers for trial use. After handing over the goods to the customer and agreeing the delivery time with the customer, we will start production and complete the product transaction according to the specified time limit. After that, we will track the goods and ask customers about their experience of using the products. Once problems are found, we will solve them in time and provide all after-sales services.
