Very useful service and a nicely written documentation too.
There's a typo you should correct: > Since installing BillForward, Wifinity has seens (should be seen).
Also, consider increasing font size in the docs. 12px is a bit too small to read comfortably. Otherwise this section is very good and comprehensive.
As an entrepreneur myself, I love the fact that there is a relevant call-to-action at every scroll level on every important page. Except just one - Customers page. Perhaps you should put one there also. Guiding visitors to appropriate next action is extremely important for conversions, this I can tell from my experience of running an A/B testing service.
