When many Douyin stores first cooperate with customer service outsourcing companies, they only hand over part of the store's customer service to the other party.

Generally, it is pre-sales customer service, because pre-sales customer service only needs to master product knowledge and sales skills, while after-sales service is related to product use, installation and other professional issues. Many stores will leave it to themselves, and apply for cooperation after confirming that the outsourcing company is really professional and reliable.
