Change the card for your plan and see your invoices and receipts in Stripe's customer portal, from Plan & usage.

In Stripe's customer portal, you can change the card that pays for your plan and see your invoices and receipts. You open it from **Plan & usage**.

## Open billing {#open-billing}

If you pay for a plan, you can manage your card, invoices, and receipts:

1. Open the account menu and click **Plan & usage**.
1. Under **Card and invoices**, next to **Manage billing on Stripe**, click **Manage billing**.

   <Mock name="card-and-invoices" alt="Plan & usage on a paid plan, the Card and invoices section with the Manage billing on Stripe row and its Manage billing button." />

1. Manage your billing in the portal.

   Your invoices and receipts come from FlutterFlow, which bills both FlutterFlow and FlutterFlow Studio.

If a payment failed, see [Troubleshoot your account and plan](https://docs.flutterflow.io/ffx/troubleshoot-account#plan-payment-needs-attention).

## Troubleshooting {#billing-doesnt-open}

If Stripe's customer portal doesn't open, a message says **Couldn’t open billing** and gives the reason. If the reason is "We couldn’t reach billing. Try again in a moment.", open the portal again in a moment.
