Can I invoice part of the service fee for selling medical devices?

part of the service fee invoice cannot be issued for the sale of medical devices. According to the relevant provisions of the Value-added Tax Law of the People's Republic of China and the Law of the People's Republic of China on Tax Collection and Administration, VAT invoices or ordinary invoices can be issued for the sale of medical devices, and partial service fee invoices are not allowed. Because part of the service fee invoice refers to the act of separating the goods and service fees and issuing invoices separately, it is not allowed in the tax law.
