Supported methods

Accepted payment methods are set by Stripe and vary by region. In most regions this includes major credit and debit cards. Additional methods like Apple Pay, Google Pay, iDEAL, SEPA, or bank debits may be available depending on your country.

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 billing

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