If your card was declined

Double-check the card number, expiration date, and CVC.
Make sure the billing address matches what your card issuer has on file.
Contact your card issuer if you see repeated declines — Magisterium AI does not decline cards, Stripe/the issuer does.
For workarounds, see Payment failed — what next?.

Organization Owners or Admins can update the organization's payment method using the same flow. Members don't see the Manage Subscription button.
