Square Launches Marketplace Site

Square, the mobile payments company that offers a mobile phone-based credit card reader, has launched Square Market, an online marketplace for eSellers without the effort or expense of building and maintaining a proprietary site.

Merchants or individuals can create a profile and manage product listings with photos in just a matter of minutes. They can then use social media such as Twitter or Facebook to broadcast deals on their sites.
Square's listings are free (Amazon's are 99 cents) but Square collects 2.75 percent of the item's sale price. eBay charges up to 30 cents per item.

In addition, Square doesn't handle fulfillment. As with eBay, product shipping is the responsibility of the seller.
