We have two other competitors (that I know of) who have a very similar offering (give or take) and all are at about the same stage (but the gap is widening).
The deals they have closed so far, are measurably better. (We even managed to get two biz owner that due to personal connections told us a bit more than fair about their dealings with one competitor).
So I am pretty certain where the weak spot is (and it was admitted to be so).
I am posting now because the competition is growing faster and widening the gap.
PS> Excellent comments and questions so far. I am reading the links and got some food for thought.
