"With their transparent pricing and stellar reputation, you really can't go wrong with Helcim. If you're a smaller merchant processing less than $2,500/month then there are cheaper options for you, but other than that there really isn't much to complain about with these guys."
"Helcim provides credit card processing the way small businesses need it: with complete transparency. All of its pricing is clearly spelled out on its website and if anything confuses you, the company provides a host of online tutorials and how-to guides."
