Verotel is really rock solid as long as all you need is processing cards.
Rock solid, payments always on time, no complains.
If you need anything on top of that, though, like building your own tools or doing the slightest customization, you are left on your own. No documentation, no support, no tools. Their interface looks like coming straight from the nineties.
But from a paysite point of view, they convert well, at least for me. It's just a extra effort to provide affiliates with tools.
