This is why sales funnel growth is so essential to success. Without properly developed sales funnel, a salesperson can’t be effective. This can mean the difference between making and breaking a sale. For instance, imagine you are working with a new client who has just bought a particular product from your company. The sales funnel clearly outlines how the client will make their first purchase, the sales person’s message has to be focused on the positive aspects of the product – the cost, the quality, and the benefits that the customer will receive through using it – and the way the sales funnel will require them into the next level of earnings with a follow-up telephone or email.
