The sales process is always there, either you sell the acceptance to customer or customer sells rejection to you. Explain?

YES .......... THAT IS TRUE ,,,,, EVEN HE REJECTS YOUR PRODUCT/ SERVICE ,, HE HAS GOT ALL THE INFORMATION / FEATURES IN HIS MIND,, MAY BE HE IS YOUR FUTURE CUSTOMER , IF NOT THIS DAY .......................... GOOD LUCK

Do a business what the customer ---Present and Prospective---  is required  and do Exist in the field for Long Term with future and growth.

I agree with the statement. But please read the para below: There are six principles to the consultative sales process: Research Ask Listen Teach Qualify Close These six principles should provide the basic outline of the consultative sales methodology that you create for your business. The methodology you create should take into account the thing you’re selling, the typical sales cycle for your business, your industry, and your buyer personas.

Agreed with Mr. Zafar and Mr. Krishna views.

That is the fact and you need to accept it.

Either convince or get convinced.

Sales is about judgement of customer psyche . Sometime you pitch with benefits of your products or with drawbacks of others. if you know what customer likes and dislikes about you or your product then sales ll be much easier. 

In my opinion if the product has been purchased by the customer it is sales and if not then its marketing. 

Yeah as simple as that ! The win & loose ruling game.
