In an article titled "TransFS Launches Comparison Site for Credit Card Processing Fees", TechCrunch profiles TransFS - one of a new breed of websites designed to help businesses comparison shop among various merchant acquirers and ISOs for the best deal that matches their needs. TransFS collects information from the merchant and then gathers bids from providers to present back. The TransFS blog provides a steady stream of helpful, merchant-related articles as well.
Another new entrant into this space is Payments-R-Us (www.paymentsrus.com) that focuses on online merchant payment solutions. Unlike the auction process managed by TransFS, Payments-R-Us offers a free "suggester" based upon the merchant answering some basic questions about their business. Payments-R-Us also has a collection of reference materials helpful to online ecommerce merchants.
