Make Them an Offer They Can’t Refuse

If you make your customer feel comfortable about a potential purchase, you’ll improve your odds of making the sale. 
Put prospects at ease by giving them a free trial period or a money-back guarantee. 
Offer additional services or features in exchange for a quick buying decision. 
Add value to your product in ways your competition doesn’t (or can’t) in order to encourage your prospect to buy from you instead of someone else.
