The query is that our shipping lines issued GST invoice without proper signing only by mentioning that this is system generated invoice (DSV Air) next one Maersk line issue digitally signed invoice as per attachment but I think this is not  approved by Authorized person , whether these involves are valid as per GST law.

The contents mentioned in Rule 54 referred in section 31 of CGST Act are must for raising an invoice in GST and it includes signature or digital signature of the supplier or his authorized representative on GST invoice.
