The customer already know your products and services.  With the help of their smart phones, the Millennials can pretty much get unbiased information at their fingertips and compare you to your competitors.  Naturally, your experience based on the number of years in business, getting involved with higher level organizations, track records and awards will no doubt help your position. However, if you have the prospective customer engaged on the phone or one on one, perhaps the focus should be asking what the client is trying to achieve and if your response is clear and unpressured, I believe you can win them over to your side of the court.
