GST e-invoice: How to ensure that the invoices printed out of the ERP systems are not printed without IRN?
Government has mandated e-invoice for businesses with turnover of more than INR 50 crores w.e.f 1st April 2021.
In case e-invoice is not issued by the seller as required by the law provisions, the invoice would not be considered as a valid GST invoice. Further, the buyer would also not be eligible to avail Input Tax Credit since the invoice would not be a valid GST invoice. This may lead to serious financial burden on the businesses.
