Shopping Cart Solutions

Viscera

I'm on the lookout for an integrated payment solution that not only helps in making mobile payments and online reporting easier but also could help streamline the AR process. I know for a fact that there are numerous software available in the market, but which one to choose is becoming a question of importance. My requirements are simple,

1. It must perform the above specified functionalities.
2. It must not take a massive hit on my finances.
3. It should make my task easy.

Considering all these, I performed a market study and came up with a suitable solution in the name of Versapay( http://www.versapay.com/ ).

My question now is, is it worth it? Or is there something I missed out?
