The Internet has changed the way business is conducted in many ways. For example, in the field of pricing, the possibility to directly interact with a trading partner has given rise to new mechanisms previously unknown in the offline world. One such interactive pricing mechanism is Reverse Pricing, which lets both buyer and seller influence the price of a product. While Reverse Pricing allows for different business models built upon diverse revenue sources, its implementation can be complex and often is very costly. This paper introduces roles and stakeholders participating in an interactive pricing scenario and describes business models based on a deployment of Reverse Pricing. Reducing both the risk and the cost associated with the implementation, a business model derived from Web Service oriented architecture is presented as an auspicious solution.
