Buyers remorse happens after the sale and if we thing about it, 'buyers remorse' is when the buyer feels remorse but it's after the sale and what's another name for feeling remorse after something has happened? We call it regret. So if you call it buyer's regret you begin to form an insight into what's happening: the buyer didn't make a good decision and now he/she is blaming you for them not doing that!
If buyers remorse occurs before the sale we call it an objection. So the point here is that it's better to have an objection than it is to have buyers remorse and that we need to help the customer make the right decisions and the customer needs to be certain and aware of the fact that he/she is making a good decision.
Many salespeople run away from objections or try to confuse the customer into forgetting about the objection that they have and of course when (it's only a matter of time) the objections resurface and it usually resurfaces after the sale has been made it becomes buyers remorse.
Whatever you do, don't hammer through a sale and close it when you can see the customer is feeling any sort of doubt or that they're not comfortable in any way! All that will happen is that they'll get buyers remorse.
Different techniques are used to overcome objections and focus the customer on what's important to them. The author's favourite are 'Sleight of Mouth'.
Whereas 'Sleight of Hand' is used for deception, 'Sleight of Mouth' isn't. It's used to subtly shift the customers focus and to educate them regarding what's important and what isn't. It's particularly powerful for shifting unfounded concerns and fears.
