What is the best way to persuade the customer to buy your goods and services?

The best way to persuade a customer to buy a product - after sales presentation, establish a rapport/ build a relationship to earn the customer's trust. One can also apply consultative sales services.

Be true , be clear, focus on that special aspect of your goods or service

It is important to first know the customer's need. Identify the need, customize your solution (not goods or service), create value chain, share benefits of the solution. Finally never compare our solution with competition

first is product knowledge about the brand. second is your customer service. If you provide the best service beyond their expectation the customer will retain its loyalty

Do not persuade. Yes do not persuade. because if they are your customers and you identify and know their buying behavior, then selling something to them is easy. The old clinche "you can sell a glass far water to a drowning man" is not true. and Educating the customer is not good enough to sell. First educate our self about our customers (both online and walkin) and findout (by listening to them first) how we can connect our products on their liking, love, dream, fashion, and even problems (mostly). If we did the first step, then selling will be easy without scientific calculator and long counciling require. 

Inform and offer the customer the full spicifications and advantages of the goods and services.
