The process of Amazon cross-border e-commerce is roughly as follows: first of all, you need to have an Amazon seller account (of course, it is the proffesional plan, the one of $40/month). Then, you need to prepare the necessary information to open a store, including company business license, tax registration certificate, bank account opening license, etc.. Next, you need to submit an application for review and wait for the review result. If the audit passes, you can start selling products on Amazon.
Specifically, you can first determine the type of products you want to sell and your target market, and then choose the right products to sell. In the sales process, you need to pay attention to product quality, price, logistics and other aspects of the product, and deal with customer feedback and complaints in a timely manner.
