What will you do if a customer cancels a purchase after spending allot of work on negotiations?

I will try to find the reason behind the order cancellation. if it is genuine reason then i will with the smiling face ask him for a chance to be his supplier in future. if i come to know it is because of misunderstanding then i will offer proof to overcome his misunderstanding. In the discussion process if i am able to uncover new needs then i will try to support my product feature that satisfies the customer need and2nd close the sale.

Hi Ibrahim,

Good evening. In my opinion, I would first try to understand what went wrong to force customer to cancel purchase. If I can rectify the things then I will help to do that but If it is not possible since it is case to case base as well as base on situation. Then at least I will help him/her for the smooth cancellation process and transparency about all dedications. I know it will neither gain sales nor change his mind but I can successfully change customer attitude about the company and related process which is very important.

First I will be asking for the reason why are they cancelling their purchase, Then that's where I would start to negotiate and think of alternatives that will help them solve what are they looking for.
