If the input information is excluded, then the invoice issued is a fake invoice, which will show that there is no such ticket. If the invoice has been voided by the issuer, "Voided" will be displayed in the inspection result; Inconsistency will be displayed if the input data is wrong.
Now you need to provide the "tax number" when issuing VAT invoices, mainly to ensure the authenticity of the invoices. Compared with the previous machine-typed ordinary invoices, the newly implemented ordinary VAT invoices have increased the tax rate and tax amount on the face, and also have a password area, which is issued by using the new VAT invoice management system. The taxpayer identification number must also be filled in on the ticket face. The taxpayer identification number mentioned here refers to the number on the tax registration certificate, and the identification number of each enterprise is unique.
