I got an international order where the customer paid me the full amount (product + shipping cost) in Indian Rupees (INR) directly from their Indian bank account.

I am confused about how to make the invoice and file GST for this:

  1. Since the goods are physically leaving India, can I still count this as an "Export" under LUT and make a 0% tax invoice?

  2. Or does receiving payment in INR from a domestic account mean I legally have to treat this as a standard domestic interstate sale and pay the regular GST rate?

I want to avoid any tax or banking mismatches later.
