Meetings, conferences and labor dispatch services belong to the State Administration of Taxation. Adding the tax registration certificate of the national tax to the local tax authority can open the meeting fee and labor fee. If the local tax invoice is used, if it is found, it may be required to be returned to be invalid, and some places may be fined.
As for the printing fee, the printing factory can only be opened. Without this qualification, you can't open it. You can discuss with your clients and open other projects.
