GST on services

Hi Needed some help.

There is a event management company., the major expenses like trainers fees , salaries , venue bookings, flights  etc are incurred here in India. Members pay the fees ( charges ) primarily online ( by using cards).  Can any one tell me the pros and cons if a company is opened in Dubai wherein only the fees ( charges ) come into the Dubai company.. Appreciate if the answer could cover the IT and GST angle also. Note that fees /charges from all other international sectors would also land in Dubai company account. So the Dubai company would have the revenues only and the Indian co will have expenses.

Thanks
