What is the best way to sell product that does not exists yet?

First know the product such as uses, quality, appearance, made of, who is the target (company, department or people) or know your market where to sell it and other things,

Second be familiar to what you sell.

Third be aware to possible question's that might concern on what your selling such as price, possible discount, availability and never give a customer a thought or thinking you don't know what you sell.

Fourth be confident on what your selling example: the tone of your voice or they way you act.

Fifth always smile even if  you don't  see the customer.

 

Your question is not related to sales, but rather to marketing. This field of marketing is called upstream marketing. It deals with anticipating strategic directions of a certian market and start a process of market shaping. When the market is adequately shaped and defined, selling the product will not be the major challenge. 

Marketing.. Create a market for the product, let the people know whats coming and make them wait eagerly. The more curious they become about the product the more it sells

This is a kind of pre sales and best way to sell is through advertising media,social media and E-commerce portals.

The best way of marketing in this case is to know the client's needs And then offer products that meet these needs in one of these ways:1- Other Customers orders were you supplied already2- Available Samples for display3- Product specifications catalogs, so I prefer to make it the last choice for display

Market the concept based on which product is going to exist same as like any real estate product such as township/residential/commercial project is marketed & sold.Their exists many proposed business modules that thru marketing of conceptual proposal are sold/comes in to existence.To ensure selling of concept/selling of product before it's existence,the concept/proto type/plan need to be perfect/with clarity/well defined such that investors/consumers are convinced to invest in it/to buy it.
