We have cleared material in month of Dec-17 to our customer in Himachal Pradesh with IGST Charged. we have filed GSTR1 showing details of supply in that particular transaction.
Now, customer noticed that there is mistake in invoice in billing address. Customer want billing address should be in mumbai with their GSTN number and shipping address is in Himachal Pradesh to avail ITC on that particular transaction which is wrongly allotted to Himachal Pradesh Customer as per GSTR1 filed by us.
Customer clarification is that they are going to make payment to us related transaction from their Mumbai Office so they also want to take ITC on same transaction.
Kindly advise can we reverse the transaction by issuing credit note stating that mistake occured in billing address against tax invoice issued to Himachal pradesh customer.
Thereafter, we will issue fresh tax invoice on current date to customer with CGST/SGST stating earlier invoice reference because in this case we will not make any material movement only rectify mistake by issuing document.
Is there any documentary evidence for the above procedure under GST law?
