I'm a SalesVu app user, and i'm sooo glad. Works perfect for my small business since i can accept cash, cards and checks and store all the transactions info in the same device. Plus, my products and price lists are saved there too and whenever i need i modify'em on the go. Also, i gave an iphone to my employees and they do the same from their cells, automatically their data come to my phone and i control everything from there wherever i'm. It's free and has the lowest fee in the market (2.7%), check it out in www.salesvu.com
