I don't see a button on the Bills window that reads "Pay bills online". The app that is used is Melio. I have a screenshot, if that helps you.

Happy Friday, @JenHgts.

I want to ensure you get the support you need.

It sounds like the Melio app might have some bill pay issues. I suggest reaching out to their support team. You can do this by going to the QuickBooks Apps tab and finding Melio. When you bring up their app, you will see support options under Contact and Support. You can also send them your screenshot if you feel that will be helpful.

Feel free to post below if you have any other QuickBooks questions. Have a great weekend!
