You can't open ordinary tickets, only full value-added tax special tickets. At present, only labor dispatch and personnel agents can issue ordinary tickets, which only issue service fees, not full invoices for all expenses. If the invoice issued by Party B is a general ticket, it will be recognized as labor dispatch by the Human Resources and Social Security Bureau in case of dispute or labor dispute. Labor dispatch means that labor dispatch agencies conclude labor contracts with dispatched workers, and the dispatched enterprises (actual employers) pay labor remuneration to the dispatched workers. There is a labor contract relationship between the labor dispatch agency and the dispatched workers, but the fact of labor payment occurs between the dispatched workers and the dispatched enterprises (actual employers), and part or all of the personnel management work is outsourced to a service agency, which is called labor outsourcing.
