This is extremely disappointing. For my business this means an additional 0.4%-0.7% fee added onto a service I currently use for free justified by features that I cannot use for compliance purposes. This new invoicing process does not qualify as an exempt financial service for a covered entity. (see subsection 1179 of HIPAA)
So unless they are now willing to sign a business associates agreement I just got a price hike for a feature that would cause fines so large they would close my business. This is going to be a PR nightmare for stripe. They have destroyed all of their goodwill, and now I will have to start considering competitors. If anyone from Stripe is here in the comments I would love to chat (email is in profile)
