[Back](./) # How can my customer update their card/bank account details in the Customer Portal? To edit card/bank details, your customers will have to: * Log in to the **Customer Portal**. * Click the **Edit** button next to the card/bank details that have to be updated. * Update the card/bank details on the card/bank details page. **Note:** Your customers can only update their card/bank details and not add a new card or bank account through the Customer Portal. However, when making payments for invoices using a new card, you can save the card for future usage for that subscription.
