Whether to open a store on Amazon or find a source of goods first depends on personal circumstances and experience. Some people have found a source of goods before opening a store, while others look for a source of goods after opening a store.

Generally speaking, if you already have a source of goods, you can start preparing for the listing of goods and the marketing strategy of the brand before opening a store. Doing so will allow you to list goods and start selling faster after opening a store.

If you haven't found a source of goods yet, you can first understand the market demand and competition through Amazon's platform, and then look for a source of goods that suits you. When choosing a source of goods, pay attention to the quality, price, and after-sales service of the source of goods to ensure that you can provide high-quality goods and services.

Whether you open a store first or find a source of goods first, you need to have a certain understanding of Amazon's platform rules and policies to avoid violating regulations and affecting the operation of the store.
