Hello there, @big jon.

I'm here to help you edit invoices in QuickBooks Online (QBO).

As I replicated your concern, changing the product/service item to an invoice will only be unpaid if the payment is unlinked. You can check the hyperlink below the paid status and see if there are associated payments. Please see the screenshot below for visual preferences.

If you didn't unlink the payment, an overload browser might sometimes cause problems with loading or formatting issues on a website, like missing images or buttons that don't respond when clicked. This also includes errors you're getting when trying to do some processes in QuickBooks.

You'll want to log in to your account using a private browser (incognito) to check if you're still seeing the error. I've provided the shortcut keys below so you can follow them:

• Press Ctrl + Shift + N (Google Chrome)
• Ctrl + Shift + P (Firefox)
• Control + Option + P (Safari)
• Press Ctrl + Shift + N (Microsoft Edge)

If it works, return to your default browser and clear the cache so you'll be able to work with a clean slate. Your cache and extensions are probably interfering with the scripts QuickBooks is trying to run on the page. However, if you're still experiencing the same, you'll want to switch to a different browser instead.
