Start-Up Steps Up to Local Product Search Challenge
[StepUp.com] aims to create a local product search destination, which would enable consumers to find things online, then buy them in local retail outlets. Someone looking for a particular model of TV, for example, could find exactly which merchants within driving distance had the item in stock at the best price, potentially saving themselves time and money.
...it's developed software that integrates with Intuit's popular QuickBooks accounting program. Merchants using QuickBooks to keep track of inventory can automatically link their product information to StepUp.com's systems.
