Product knowledge leads to confidence in salespeople and helps create value for customers. Research shows that knowledgeable staff sell 87% more than those without product knowledge. As 50% of customers seek expert advice on purchases, knowledgeable sales associates can better meet customer needs and lead to happier customers who buy more confidently and spend more. Strengthening communication skills, boosting enthusiasm, and growing confidence allows salespeople to better convince customers, who then trust the product and salesperson, leading to more sales and fewer returns.
