WebStack’s Syndicated eCommerce Networks enable Home Builders to sponsor Online Service Malls to residents of their new-home subdivisions. The mall’s e-commerce mini-shops are operated by the various sub-contractors (HVAC, electrical, plumbing, etc.) who actually constructed the homes in each subdivision. Homeowners schedule service calls and purchase service contracts or replacement parts using their mobile devices. Such services support long-term relationships and upgrade home sales as the homeowner's family grows.
