I can't update bills or mark them as paid. I also cant access the chat feature. Says chat during business hours after 6 am, it's 9 am here.

I have information on why you can't mark as paid a bill using Quickbooks Online (QBO), Colen.

Usually, you can mark a bill as paid after you link it to pay bills in QBO. In your case, you may experience some browser issues. With this,  I advise using other supported browsers and utilize your QuickBooks there. If the issue persists, I suggest performing some basic browser troubleshooting to rule out the possibility of having issues with your browser. Know that display programs accumulate temporary internet files that can affect your browsing experience. Too many internet files can sometimes change how your QBO company behaves, resulting in errors when performing tasks. See the following keyboard shortcuts for suitable browsers to open a private window:

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

Check out this article for a step-by-step process on clearing your cache: Clear cache and cookies to fix issues when using QuickBooks Online.

Moreover, please note that the chat support availability is based on Pacific Standard Time (PST). I suggest waiting for the chat feature to be accessible during your scheduled timeframe.

On the other hand, you can modify your vendor transactions to correct any mistakes while recording some vendor entries in QBO.

For any future questions regarding managing a bill or any QBO feature related, don't hesitate to comment below. I'll get back to you. Take care!
