Update your card and billing details from the Stripe Customer Portal, which you open from Settings → Account.
Steps
Go to Settings → Account.
In the Subscription Plan section, click Open Customer Portal.
In the portal, update your payment method, billing address, or view invoices.
Save. Changes take effect immediately.
What to expect
The Open Customer Portal button only appears for the account owner. If you don't see it, you're signed in as a team member — ask your account owner to make the change.
The portal is hosted securely by Stripe, our payment processor. You may be asked to confirm your details there.
A card update won't change your plan or billing date — it only changes how you pay.
