Simple ! They dont earn any profit ! Yes. None of the ecommerce company in India has earned a single penny under the term “ Profit “. Yes they have revenues but not profit.
Profit = Total Revenue - Total Cost ( Net profit is amount let after paying all costs, taxes , etc ).
Again neither flipkart, not amazon nor any other company has made any profit.
Future estimates ? For atleast 3–5 years they wont make any profit.
They how will they survive ? By raising capital from investors !
