Gst on export engineering services

Hi All,

I am kind of confused about GST charge on exporting engineerings services from India.

Scenario is my startup is based in India and client is based in USA. Payment I am receiving in USD so should I charge GST to client? If client only pay dedicated amount as per the project cost for example 500 dollars for 1 task then do I need to pay GST from my pocket?

Please help.

Thanks,

Mayur
