If you don't have the problem of getting paid on time, every time (or at all) by clients, then this product probably isn't for you.
Stripe costs 2.9% + 30c per transaction (no monthly fee) and has example code you can copy and paste into your site (for free). I can type email reminders to clients myself, or setup a script to send stock messages automatically (for free). And when I get paid, I get paid directly to my bank account (where I have full control over it, which I can use to pay bills and eat food).

I'm not trying to rain on your parade. I'm just curious what the actual benefits are. Maybe I'm missing something. Please explain it to me. From the little information on the webpage, I currently feel it isn't worth it.
