There are lot of companies which had started using electronic signatures for issuing the invoices. However, even after authenticating these documents with the electronic signature, the taxpayer were required to put actual signature or digital signature on the invoices as per the Rule 46 of the CGST Rules, 2017.

“Provided also that the signature or digital signature of the supplier or his authorised representative shall not be required in the case of issuance of an electronic invoice in accordance with the provisions of the Information Technology Act, 2000 (21 of 2000).”
