The transaction information of enterprises that use tax-controlled special equipment to issue electronic invoices shall be electronically signed through the electronic invoice service platform of tax authorities. Therefore, there are tax-controlled signatures and enterprise electronic signatures on electronic invoices, and there is no need to affix a special invoice seal. Taxpayers have the right to reject invoices without electronic signature.

If there is such an invoice without electronic signature, the reasons can be analyzed in combination with the situation:

1. The seller did not generate a seal during the issuance process, so it is recommended to contact the relevant service provider for handling;

2. The buyer did not have an electronic signature when printing. First confirm whether there is an electronic signature when the electronic invoice is opened in pdf format. First, check whether the computer lacks corresponding controls or the electronic signature cannot be displayed due to system settings.

The electronic invoice issued by British tax is replaced by electronic signature, and there is no special invoice seal in the lower right corner of the electronic invoice page. When receiving such invoices, there is no electronic signature and they can be used normally.
