3 months is indeed a long time for us to have to wait for revenue. However, it's good for users because if they get to the 100 transaction limit, it means that they use it, which means that they get value out of it and would be more willing to pay to continue to use it. Or at least that's our line of thought. Also, it takes at least a month of transactions to be able to look at stats and get some insights from your spendings.

For existing users, we'll set the transaction counter at 0 (zero) when we launch this. Also, we are thinking of offering them 50% lifetime discount.

I think the other project you're talking about is http://thebirdy.com/.

I'm glad you're thinking about your existing users. I don't have a problem with your plan but I would suggest cohort analysis to test different free trial versions. Eric Ries talks about this on his blog and in his book.

Also the sure I was referring to is in a completely different niche.
