Answer:
showing sensitivity to customer needs and opinions.
Explanation:
A sales proposal is only going to be effective if it focuses on satisfying the customer's needs and how the customer perceives value. A salespersons ability to uniquely address a buyers problems and needs can make a huge difference during a sales presentation and proposal.
Canned proposals are usually not very effective since they are basically similar for every type of customer, it pays little attention to the buyer's requests or needs. Written proposals provide permanent record of the offer, intentions and possible claims.
