In 2021, Taobao C stores need to be upgraded to corporate stores to continue operating. On the Taobao platform, corporate stores have more advantages and rights than personal stores, including better credibility, richer product categories, more flexible business methods and better customer service. In addition, the Taobao platform is also gradually strengthening the supervision and management of personal stores, requiring personal stores to provide more qualifications and certification documents to protect the rights and interests of consumers and the standardized operation of the platform. Therefore, if you want to operate on Taobao for a long time, upgrading to a corporate store is a good choice. After the upgrade, you can better manage the store, improve your credibility, expand your customer base and increase revenue. At the same time, the Taobao platform will also provide more support and help to enable corporate stores to develop better.
