Yeah and it worked last time. As a Stripe customer myself with way less revenue than OP, I worry about this a lot. How can any sane company terminate any client with revenue (any size) without having been in contact to sort issues before hand or if not possible, to terminate them with a grace period?

This is insanity.

You don't know what the OP has left out of their post. I am pretty sure Stripe didn't terminate a major customer like that overnight because some admin or bot got bored.

Correct, but they stated they're in delayed fulfillment within the travel vertical.

Google often does that to Google play developers so I don’t see why stripe can’t?
