Aarel Import Export Private Limited

1. Whether the procedure to raise the invoice from Mumbai Office for imports received at Paradip Port, Odisha where we do not have any separate GST Registration and Charge IGST from Mumbai to our Customers is correct? or do we have to take separate Registration in the State of Odisha for the below mentioned transactions?

2. If we do not need separate registration in Odisha, can we do the transaction on Mumbai Office GSTIN, then in case of issuance of e-way bill is it correct to Mention the GSTIN of Mumbai and Dispatch place as Paradip Port?
