Hi Ketan, thanks for reaching out. To enter the invoices in foreign currency, request you to turn the 'Multi Currency' option 'On' and then create a customer in 'foreign currency'. You should be able to enter the invoice in foreign currency.
Hi ketan3, thank you for your reply. When you enter the export invoices, please select the 'Place of Supply' as 'Other Territory' and select the tax code as 'Exempt IGST(0%)' to have the GST compliant invoices
Hi ketan3, thank you for your reply. You can select the same place of supply and tax code for credit note also. Please select the invoice number on credit note form while entering the credit note
