What address and GSTIN do I need to provide in the e-invoice section during the checkout process?
If your business entity has multiple GSTINs, then provide the GSTIN to which you want the invoices issued in the e-invoice section. Provide the address that corresponds to the billing or invoicing address for the GSTIN. By default, the address provided in the billing address section is pre-populated onto the e-invoice section. It is possible to update this address.
