I have raised an invoice to a US customer for USD 320 for my customized graphics development. I have mentioned 0% IGST as it is "Exports of Services". They sent me money from their Bank of America account in US (Philadelphia) this time and I received it as a direct/pre-converted INR deposit to my current account. Is it still Exports of Services with 0% IGST? 

I am asking this because previously when they sent USD 320 from some other bank, I received it as FX Inward Remittance, and I have to convert it and deposit into my current account from the portal of local Indian Bank (Axis Bank).
