Running two business simultaneously has their pros and cons.
And I am running two different business, with different class of people. Let me put a light,
Client : Needs a services, Customer : Needs a product.
Client : Needs a result, Customer : Needs an experience.
Client : I give him what he needs not he want, Customer : I will try to give him what he want.
Client : I charge him after giving my services, Customer : He pay before they get products.
