Taobao stores and Douyin stores are two different platforms, belonging to Alibaba and ByteDance respectively. If you already have a Taobao store and want to sell goods on Douyin, then you can consider opening a Douyin store.

After opening a Douyin store, you can sell goods directly on the Douyin APP and enjoy the marketing and promotion support of the Douyin platform. In addition, Douyin stores also support a variety of payment methods, including Alipay, WeChat Pay, etc., to facilitate user purchases.

However, it is not necessary to open a Douyin store. If your Taobao store is already operating well and has a stable customer base and sales, then you can continue to operate the Taobao store and promote and sell on Douyin through the link of the Taobao store.

In short, whether you need to open a Douyin store needs to be decided based on your own situation and business strategy. If you want to do business on the Douyin platform and believe that Douyin stores can bring more opportunities and support for your sales, then you can consider opening a Douyin store.
