Abstract: Embodiments consistent with the invention include a system 5 that a sales representative may use to determine the financial characteristics of sales that he or she has already made to an account, or to evaluate the financial impact of sales opportunities to an existing or potential account. A computer implemented method of presenting financial characteristics of sales opportunities entered by the user is provided. The sales representative may prefer to evaluate sales opportunities by specifying product and potential revenue. Alternatively, sales representative may prefer to evaluate sales opportunities by specifying product and quantity. Once a sales representative can see the cost and contribution that particular items or accounts have, he or she can then focus on selling the higher-contribution products to maximize the benefit of his or her sales efforts.
