As a service provider or vendor, I practice WYSIWYG - What You See Is What You Get! Meaning, I do not promise anything I cannot deliver.
Whatever I say about the product or service I promote, I always tell its benefits and weaknesses, so much so that the customer may not be expecting way beyond what the product or service is not.
Second, my secret is to serve with a heartfelt SMILE! This is a very effective tool to convey that you are pleased to serve the customer.
And, this gives them a sense of importance.
Third, I speak gently to them.
Paying attention to what they are asking or saying, and answering them accurately gives them a sense of ease.
Prompt service is the key to keeping customers! Most of all, I say Thank You after closing the deal, expressing my willingness to serve them again.
These are but few of the elements to provide customer satisfaction.

There are several ways to Start First: 1 - The customer is always right.
2 - If the customer information outdo just saying is true and does not object to let him speak with his smile 3 - If the customer does not know anything Immediately place the product in his hands.
4 - small smile is the key to your access to his heart.
5 - some jokes and playful spirit may be useful.
6 - Do not tell the customer you want to buy?? But give him need his hands and let him be willing to pay.
