How can you make a customer buy what they don't want to buy?

tell him thebenefits of the product and how many peaple by it

if u don`t create the need for the product they will never buy so it`s you and your skills .

As a salesperson and as a customer i think you cannot make a customer buy something they dont wanna buy.
But i think that you can influence their decision to buy by create in their person the need.
You have to study the needs of your customer and evaluate before if its a customer or just a prospect to define a good strategy to influence their decision to buy or not your product.
Once, the customer is through your sales pitch, he has seen your presentations, your catalogues, he knows about your products, he might express desire for it.
An active customer will move ahead himself.
A passive customer however will mull over it some more and you will probably get a reply that he will consider your proposition.
So how do you induce a passive customer.
1) See to it that customer is convinced – If the customer is not convinced dont try to induce him.
Instead let him mull over the product and go for a second sales call or even a third.
Ask him to close the sale only once YOU are convinced he is going to buy.
YOU need to sense when the time is right to go all out in convincing your prospect.
2) Understanding the customer is very important.
Some customers will be induced when you ask them directly.
Give them a trial period for the product, give them a time frame in which they have to decide or give them any reasons due to which they have to make a sale within the specified time.
This makes a passive customer act.
3) Use examples – Give him examples of within his industry or vicinity in which your company has sold the product.
Use excellent customer service examples, product examples, sales examples.
Ultimately get the prospect convinced he is not the only one using the product.
If your prospect knows there are others out there he is more likely to buy a product.
4) Give him some time but in the end go direct.
If the customer is avoiding for too long, its better to not waste time on him and ask a direct question, you will get a straight answer of what the customer is thinking.
For me those 4 steps are essentials to turn on the decision of the customer / prospet to buy the product.

originally it depends on your skill in discovering a hidden need then attach it to your products or to create a fake one that your product fulfill it the best.

follow triple R rule,(Relax,Relate & Rock & Roll).never try to sale a product.just get along with a customer and product will be moved.

Any customer who comes to you, have a possibility to buy your product , so you have to check the customer needs and you could explain to the customer how useful for him the product you have, making sure that you are aware of your product very well

- Attractive and innovative campaign To sell a product to a unwilling customer its always necessary for a customer to notice your product first.
- Study the customer needs, Always know why the customer is unwilling to buy your product, what is the reason for his lack of interest.
- Never start the conversation with a price.
The only time you give your customer your asking price is after you have explained to them the major advantages they would benefit from buying your product or services.
- Never hurry the sale.
It is always to your advantage to give the customer time to think it over.
This shows them how considerate you are towards them, thus, the start of a business relationship in progress.
- Come out with your best offer.
Don't hesitate to say the asking price.
Customers will always ask for the "concessions" they can get first then they would bounce the offer back and forth between you and your competitor.

first you create the need for the product then you mention all the benefits of this product    

suggest to him try it first , when he used to the product he can't let it

9 Steps to make a customer buy what they don't want to buy?
1- Talk with your customer.
Sounds pretty basic, right? But so many salespeople simply nod and smile, or hover, rather than chatting the customer up.
Talking to the customer will allow you to learn what things the customer is interested in.
This will help you turn a little sale into a bigger one.

2- Know your product.
The more you know about your products, the more you will know about how different products can add value to the product your customer is buying.
Let the customer know how these things can make the product they want better.

3- Notice what the customer touches, picks up, talks about, and use it as a springboard to suggest other items.
Being attentive means paying attention to what the customer seems interested in.
Let's say you're in a book shop.
Your customer is perusing the sci-fi section and keeps on touching or looking at (or talking about) the Chronicles of Narnia.
Ask if he or she has read them all, ask if s/he has read the Lord of the Rings, the His Dark Materials series, or the Spider wick Chronicles.
Or Harry Potter, for that matter.
See the step above - knowing the merchandise is very helpful here.
All of these are similar, but distinctly different book series, each with three or more books contained in the series - great up selling here if you can interest your customer in one or more of them.

4- Don't decide what a customer can afford.
Let the customer decide.
Many salespersons hesitate to show one more item to a customer already carrying an armload of merchandise, fearing that the bill will freak the customer out.
Guess what? Not your problem! The customer is an adult (hopefully, or at least has some adult supervision), and knows the state of his or her finances far better than you do.
Don't choose how much this customer is able to afford.
If s/he can't afford an item, he or she will let you know.

5- Accessorize.
This is the surest "upsell." Never let a customer buy a book without suggesting a bookmark or a "crystal cover" for the dust jacket.
If a customer is purchasing a DVD set, try to recall if there are books related to it, pens, bookmarks, journals, mints, whatever! If a customer is purchasing a journal, suggest a pen, a book jacket.
Try to remember the things you would want if you were the customer making this purchase - if you bought a camera, you would want to buy an extra battery, a case to carry it in, extra flash card and a card reader so you could get your pictures off to your computer - stuff like this is very important.
Put yourself in the customer's shoes and think - if you were buying this, what would you buy with it? You're a consumer, too, and your opinion is valid and worth as much as anyone else's.

6- Be specific.
Customers won't agree to buy some unknown thing.
If a customer orders a hamburger, don't say "Can I get you anything else with that?" Instead, choose the most likely item you think the customer might want and say "Can I get you an ice cold Coke with that?"
7- Put the items into the customer's hand.
Don't just point at stuff.
Pick the items up and hand them to the customer.
Once in his or her hand, it's a lot harder psychologically for the customer to walk out without anything.

8- Close the deal.
Okay, you've got the customer in the palm of your hand.
S/he's picked up a book by an author you suggested in addition to the book she came for.
You've offered her crystal covers for her dust jackets, and she agreed this was a good idea since the books are first printings.
You've chosen a bookmark for each book, showed her some nice bookplates (she declined, no problem), and offered her the chocolate truffles near the cash register.
If she's still looking lingeringly at the store, ask if she'd like you to put the covers on her books while she browses some more.
Hold her items up front for her, ready to go when she is.
Accompany her to her other areas of interest, and when she's finally ready, don't hesitate - if you do, she may start to have early buyer's remorse.
Many people second guess themselves if given too much time to think, so close the deal now.
Say, "Okay, do you think that's enough damage for one day?" and smile, leading her to the cash register.
Ring her up, and ask one last time if she sees anything else she can't live without today.

9- Assure your customer that s/he has made good choices.
This is the single most important part of this selling method.
It is very important that you reinforce your customer's purchase at the end of the sale.
Say something like, "I know you're going to enjoy this - I'll be very interested to know what you thought about it when you're done." At the very least, you'll avoid returned merchandise from someone who had second thoughts after buying.
At best, you'll form a bond with your customer and possibly win a patron.
This step requires sincere interest in your customer and cannot be faked.
You must feel genuine excitement and enthusiasm for what your customer has just bought from you.
It's okay to repeat or rephrase some of your conversation during the sale, but avoid parroting the same lines.
The easiest way to generate this part of the sale is to think back on things that you yourself have bought.
Which times were you happy to have something? Had you waited for it, or did you rush out to get it as soon as it was available? Was it an impulse buy, or part of a plan? Use questions like these to increase your awareness of what your customer has just done, and enrich the experience.

So simple,You ask him to try your product and if not again you move to another person and try to get back to the first one another time.
