New Manage the cards saved on your account directly inside ShingleAI — no hop to the Stripe-hosted portal needed for routine card changes.

Prerequisites

  • You must be an Owner or Admin to view or change payment methods
  • An active Stripe customer record (created automatically the first time you save a card or upgrade a plan)

Open the page

  1. Navigate to Settings > Account > Billing
  2. Click Manage payment methods in the page header
You land at /settings/account/billing/payment-methods.

What you can do

ActionWhat happens
Add cardOpens an in-app dialog with Stripe’s secure card form. After your bank approves the card (including any 3-D Secure step), it appears in the list.
Set as defaultMarks the card as the one used for subscription renewal, credit top-ups, and consumable overage charges. The current default’s row shows a Default badge.
RemoveDetaches the card from your account immediately. Confirm in the prompt before the card is removed. You can’t remove your last card — add a new one first if you want to swap.
The first card you add is automatically promoted to default.

Empty state

When no cards are saved yet, the page shows an empty state with a prominent Add card call-to-action. The same dialog opens whether you click the empty-state button or the Add card button in the page header.

Default card behavior

  • Exactly one card is the default at any time. Setting a non-default card as default replaces the previous one.
  • If you remove the default and other cards remain, ShingleAI automatically promotes the most-recently-added remaining card on the next page load. To pick a different default, use Set as default on the card you prefer.
  • Subscription invoices, credit top-ups, and overage charges all bill the default card.
  • At least one card must always be on file. Removing your only card is blocked; add a replacement first.
