Becoming good at selling is a nuanced skill. Many pivotal techniques are often not communicated properly in the training and onboarding phases, leaving many members of the sales force "crippled" before they even get into the field. We set out to discern the "best practices" of selling, and the underlying causes as to why they work. Through meticulous research obtained via study of experiments, sourced articles and other academic papers we compiled a thorough outline detailing the most efficient ways to build a relationship with the buyer and close the sale. From there we discussed the methodology to implement those skills into a complete sales training program. This paper serves as an informational guide to the necessary skills to complete a sale and how to train for those skills.
