Gst invoicing

Respected Members,

We are a firm undertaking trade in specialised steel. We are registered under GST in Hyderabad, Telangana as our registered office is located here. We do not have any offices any where else. Now, we got an order for supply of our produts in Chennai, the goods are also located in Chennai, so the supply of goods will be from Chennai to the buyer in Chennai, however, the invoicing will be done from Hyderabad. We don't have GST registration in Chennai, so we can only invoice from Hyderabad.

Is this accepted under GST? Will it be an Intra-state supply or Inter-state supply?

Please advice.

Thank you.

Regards

Chandana
