My response assumes that there is a need for a complex product. In general, unless there is a specific need for complexity, complexity is incompleteness, lack of polish, or a failure to target needs properly. Customers don't want complex products they want simple products. However, showing a simple "slice" of a complex product that addresses a larger problem or need makes sense, and is a case for the complexity.

Understand your customers needs and how you provide value.

The existing comments provide a good jumping off point, but with few specifics we can only speak in general. If you add more details I will follow-up.

The bottom-line is that your customers don't care about your product. They care about how your product helps them.

You want to understand the processes and problems that each individual customer is dealing with. If you don't have intimate knowledge of these already you have to ask strategic questions that reveal these.

Once you understand this, and demonstrate it in relevant terms to the customer, ask for the business. This not meant to be sarcastic or condescending at all. I have been in numerous meetings with smart people, executives, sales people. So often, they understand the need and demonstrate it, and then never ask, and they wonder what happened. Typically, it helps if you are confident when you ask.

I would add that complex is a relative term. If your product can't be put in terms that are easy for your customer to understand then you have the wrong customer or the wrong product.

As noted above -"The bottom-line is that your customers don't care about your product. They care about how your product helps them."

Selling me an apparatus that I can ride and has a combustion engine with wheels will not sell me on a product. Telling me that a machine can get me from point A to point B easily and fast and it's called a car. Will definitely get my attention.
