SellSimple has launched an iOS application that allows a user to sell an item across several platforms at the same time. The app can post listings on sites like Craigslist, eBay, Etsy, Facebook, Twitter and other outlets, including the SellSimple Marketplace. All a user has to do is take a few pictures of their item, enter some details and push the listing out to the desired channels. SellSimple takes a 5 percent cut only when an item is sold. Buyers can purchase items with a credit card. This could be an intriguing option for merchants who sell goods online. SellSimple plans on adding a more robust search feature in the future. A loyalty or rewards program for buyers and sellers would also be nice, but let’s see where this goes first. (The Next Web)
