One of your customers has intimated to us that they have changed theirs. They want us to update their Feb 2022 bills with their new GSTIN so that they can take the credit.
We are required to follow e-invoicing provisions under GST. So, we have already created all their E-Invoices for March and Feb 2022 which cannot be canceled now on the e-invoice portal. Further, e-way bills were also created by us. The goods have been already delivered to the customer.
