As far as I know, the official receipt needs the following process:

Element:

1.

2. Billing unit

3. Taxpayer identification number

4. Bank and account number

5. Date

6. Payee

7. Quantity

8. Summary

9. Special seal for invoice

Precautions:

1. Please ensure that the information filled in is true, accurate and complete.

Once the receipt is issued, if there are any changes, both parties need to agree and sign.

This receipt is only used as a receipt and has no legal effect.
