The options to pay with a credit card and debit card are readily available in QuickBooks, Denny. Let me assist you in ensuring that your customer can successfully process payments using these methods.

To ensure it works properly, we need to conduct some browser troubleshooting on your customer's end. They can access QuickBooks using the browser's incognito or private mode. Here's how:

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

If the credit card and debit card options appear in incognito mode, it likely means that there's cached data affecting their view. I recommend clearing their browser’s cache, logging back into their account, and then proceeding with the payments.

If the issue continues, I recommend contacting our live expert support team for additional assistance. They are equipped with specialized tools that can provide a deeper diagnosis of the issue.
