I feel like some of the best strategies to use to build relationships with potential customers are to listen and not only retain the information, but to understand what they're saying and to understand the position that they're coming from. Putting yourself in their shoes gives you a better idea of how they might feel about the situation and will give you a better idea of how to work with them on certain projects in the future. I also think it's really important to build trust within a relationship, so if you say you're going to have an appointment, you hold that appointment and you maintain that relationship.
