Sounds useful. Not sure I’d trade a 1% reduction in revenue across the board for this though.
That being said we still want to charge something to indicate a level of seriousness to the use.
For some context on how we arrived to the figure the ~1% figure is in the low end ballpark for how much we saw companies spend internally on their billing systems built in house, and its slightly higher but still in the same range as other billing providers.
If someone is running $100m through your system they are going to call to negotiate anyway, you don't have to advertise it.

Though, I understand the apprehension behind having to pay 1% of the revenue. It is a psychological thing mostly (in a way, the potential costs seem bottomless like with card payments, even though 1% is actually a super-good deal for small tech shops).
