Query:

We are an Indian service providers working as Intellectual Peoperty mediators. 

How we work: 
we connect clients and service providers across the globe. 

Example: One US client need some patent/trademark registration in China.

US client will approach us for the task. We will connect with some china based IP attorney regarding this task. The US client pays entire amount (our professional fees, China Attorny fees and China Govt fees) to us. 

We keep our professional fees and pay the portion of China Attorny fees and China Govt fees to the Chinese Attorny for their processing). 

In this scenerio. How we will raise the invoice in compliance with GST? 

Does this kind of arrangement falls under 'Intermediary'? 

Should invoice contain entire amount received from US client or it should contain only our professional Fees?

What should be the GST treatment? 

Kindly guide.
