A method includes generating a delta price and generating a final price using the delta price. A process and system provide an ability to determine a product's final price with a selected set of features in which multiple configurations are to be generated. The ability to determine such final prices can be based on the ability to determine the change in price between one configuration of a product and that of another product configuration (e.g. the product configured with the desired feature(s)). A customer is able to select one or more features, and so view the effect on the product's final price, as well as compare the prices (and incremental price differences) between various configurations of a given product. This increases the likelihood of the purchase being made, because it provides the potential purchaser with the final price earlier in the sales cycle.
