How can I change my credit card/payment method for a product (quickbooks online)? I have added the card to my account already but cannot update the payment method

I'll guide you on how to change your payment method, Bernard.

Let's begin by signing in to your QuickBooks Online (QBO) account as a primary admin. Then, proceed to the following steps below:

1. Click the Gear icon, then choose Subscription and billing.
2. Tap Edit to your payment method.
3. Follow the on-screen instructions, then save.

If you're unable to update your billing details or receive an error message, I suggest performing some basic troubleshooting steps. QuickBooks behave strangely due to browser-related troubles. Start by signing in through a private window, then perform the activity again. here are the keyboard shortcuts:

• Google Chrome: Ctrl + Shift + N
• Safari 11 or newer: ⌘ + Shift + N
• Mozilla Firefox & Microsoft Edge: Ctrl + Shift + P

If it works properly, you can return to your default browser and clear its cache to start fresh. If not, you can use another supported and up-to-date browser because the one you're currently using may have a temporary issue with the system.

You'll want to update your credentials in QuickBooks. Refer to this article: Update or change your Intuit Account sign-in information.
