Change b2b invoice value as per buyer information

This discussion addresses the possibility of amending a B2B invoice issued several months prior. The consensus is that direct amendment of the original invoice after a significant delay is generally not advisable. Instead, suppliers should issue a credit note (for reductions) or a debit note (for increases) to adjust the invoice value, referencing the original invoice details. This approach aligns with provisions like Section 34 of the CGST Act.
