It may be you're experiencing some browser hiccups, PTMel.

When you visit a website, the cache will store any information and will take the space on the computer's memory. If it'll overload, it will cause unusual behavior.

We'll have to perform basic troubleshooting steps. To start with, let's access QuickBooks Online through a private browser. This is the best place to identify web issues. Here are the shortcut keys:

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

If you're able to see the billing page, let's go back to your main browser, then clear it's cache. This helps us refresh the program.

Although, if you're still unable to go to the billing page, I'd suggest reaching out to our customer care support. An agent will take a closer look at your issue. They can also update your payment method. Just follow RCV's steps on how you can reach out to us. 

We're just here if you have other concerns. Swing by anytime.
