Wow. Interesting.

As having having used several at different scales in both tech and business capacities, general feedback on payment gateways is:

  - developer support (libraries, examples to get apps going quickly and sandbox APIs)
  - clear communication of due-diligence process for new accounts
  - advance notification for production changes
  - discussion of security and audit standards (makes customer due-diligence, internal selling easier)
 

Stripe and others shake things up a little whereas traditional US/multinational basically didn't care about anyone, especially customer service unless you happen to be a Fortune 100 that can yell at their mgmt at a high level.
