Your intro should be the stage of the sales process where you gain the interest of the prospect to want to hear more.
If you are in telesales this is the where you want the prospect to give you some time to present. If you are in face to face sales, you want the appointment to sell.
The introduction is not the stage of the sale where you sell.
This is not the part where you mention prices, costs etc. You can mention general ball park figures or potential savings but this is done just to spark interest.
If the prospect asks if you are selling anything, my response is: give me a few minutes of your time Mr Prospect, who knows at the end of our time together you may just be buying and I won’t be selling. This is said as a joke and can be a crucial ice breaker in the introduction.
