Webgility (a provider of ecommerce and QuickBooks integration software) is making that task possible with eCC Mobile, an iphone application that enables merchants to manage their online store through their mobile device.
eCC Mobile currently supports the Magento ecommerce platform (Community, Professional and Enterprise editions) and will be integrating with other shopping cart platforms this year, including X-Cart, Ubercart, Open Cart, ZenCart, osCommerce and many more.
eCC Mobile is compatible with iPhone, iPod touch, and iPad, and requires iOS 4.1 or later. Users of the application can monitor sales performance, view order status, review store catalog, and update product details (pricing, quantity, etc.). You can also directly contact customers using native iPhone features, such as text messaging, email and phone.
