This is really great stuff. I've had a few interactions with Benjamin in the past and he's a real pro.

While I haven't seen the actual code in the SaaS kit, I imagine it's top notch.

Billing is one of the trickiest things to get right. It's also a big time suck. $249 is nothing compared to the number of hours you'll spend writing, testing and re-writing your billing code. Believe me, you don't want to mess up your billing infrastructure.
