There is a prerequisite for opening a group purchase in Tik Tok, that is, you must complete the enterprise number and complete the blue V certification before you can open it. Enterprise number and blue V certification are indispensable. If it is a personal number, there is no way to open the group purchase function, because the personal number cannot authenticate the blue V. At this time, it can be solved by changing the personal number to the enterprise number and then authenticating the blue V. The certification fee for the blue V is 600 yuan, which means Tik Tok has to pay for the group purchase, and the fee is 600 yuan certified by the blue V.
