As per my view, since the services being provided by your client as intermediary services as per section 2(13) of IGST Act. Section 8(b) provided that in case of intermediary services, the place of supply will be the location of supplier of service, hence place of supply will be India. The transaction will not qualify as export.
As per the definition under section 2(6) of IGST Act, export of services” means the supply of any service when,––
(i) the supplier of service is located in India;
(ii) the recipient of service is located outside India;
(iii) the place of supply of service is outside India;
(iv) the payment for such service has been received by the supplier of
service in convertible foreign exchange;
In this clause (iii) is for place of supply, which is India, therefore not qualify as export of services.
Thanks.
