How can we leave different impression on customer during the call ? They remember my company profile and offer business when they need.

First greet them properly and listen carefully the customer and know what is his/her need and provide them a unique and powerfull solution, and ask them that is he/she is satisfied with this solution or not and incase he/she is not satisfied with ur solution provide them another one clear his all doubts And surelly u pay a good impression on the customer and if he/she is satisfiied with ur solution he/she will surelly consult u again and buy ur product.

We are expected to do all that make the customer to say the following: 

• You know me, you remember me
• You give me choices
• You make it easy for me
• You value me
• You trust me
• You surprise me with stuff that I can’t imagine
• You help me better, you help me do more

This way one can leave very positive impression.

You have to call starts salute

The question on the customer a good way

And selecting the speech useful

And that the customer needs to hear from him
