Quadrant Data Systems, Inc., our colocation facility for over 12 years, came to us looking to upgrade their static website to something more expansive that would allow customers to easily order their colo cabinets. We developed a front-end calculation system that lets visitors enter different configuration options for their servers and find out the respective prices. For example, with the virtual servers, potential customers can customize the features and operating system and see the prices for the various combinations. QDSI can set pricing for each of the options through the site administrator. Most of the products have setup and monthly costs that need to be set. This expanded e-commerce site is a perfect case study and example for sites that need to have functionality that allows for setting different prices for the same products depending on the level of customization.
