Can't add ne bank card - error code 81819

Let me share some information and help you in add a bank card in QuickBooks Online, info1731

Make sure you're logged in as admin to change your billing info, or payment method for your subscription. Also, you need to verify the card details and check if the address for the card matches the address in your QuickBooks settings.

If you're still receiving an error message, we can perform troubleshooting steps to ensure there are no underlying browser issues. To start, let's open QuickBooks in a private window.

We can use these keyboard shortcuts to open one:

• Google Chrome and Microsoft Edge: Ctrl + Shift + N.
• Mozilla Firefox: Ctrl + Shift + P.
• Safari: Command + Shift + N.

If that works, you can go back to a regular browser and clear its cache. Outdated and corrupted internet files can also be the reason for some unexpected behavior.

You may also try using other supported browser that works perfectly with QuickBooks Online.

Let me know how it goes or if you still have other questions about adding a bank card. I'll be here to help. Have a good one.
