Online sales-e-commerce, without store marketing, is also a trend of future social development. People like to buy good and cheap goods, and this trend will get closer and closer with the acceleration of people's life rhythm. In view of the problem you mentioned, first of all, the source of supply is that you get the goods from agents or manufacturers. If you can get the goods from the manufacturer, they will generally not supply you without the company's three certificates. Some products have strict sales channel management, especially bulk commodities, but the general agent can get a slightly higher price, followed by applying for an account. This is very simple. I don't know whether you open a shop in Taobao or Yi Bei, or have your own website. If you open a shop on Taobao or Yi Bei, just apply directly. If you don't know much about store maintenance, finding a professional website designer to help you do it can also decorate your facade. In fact, online stores don't need to advertise, such as Taobao itself, but if you are a newly established store, you may need a process and consumer awareness. The most important thing is the quality of the products you sell. After that, once the business starts, customers will keep coming, and you should learn to use the word-of-mouth of the masses to promote it for you. As the saying goes, the golden cup and the silver cup are not as good as the people's reputation. If the products you sell are good, express delivery or logistics will pick them up directly. Logistics is not a big problem, but the most important thing is to choose a good logistics company.
