The sales approach and presentation techniques are vital not only to the success of the sale, but to building long-term relationships with customers. The sales approach starts when the salesperson first comes into contact with the buyer, when the actual discussion about the product or service begins. The sales presentation is when the salesperson uses an actual presentation, which could be by speaking or by using visual demonstrations to highlight how the product or service will be of benefit to the customer. The goal of the sales presentation is to sell the product or service to the prospect.
