Why can't I use my online account anymore? I never cancelled it.

I'm here to make sure you'll be able to create invoices in QuickBooks Online (QBO), ourpadyourpaws. 

We can perform some troubleshooting steps to fix this. There are times when the browser is full of frequently accessed page resources, which causes some errors or unusual responses. 

Let's start accessing your account using a different or private browser. You can use either of these shortcut keys:

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

Once logged in, try to create invoices again. If it works, I recommend clearing your browser's cache. Doing so will remove the historical data and access QuickBooks with a clean slate. You can also switch to a different supported browser.

Additionally, I recommend visiting the following article to learn about how to print invoices or get a link to share with customers listed in QuickBooks: Create invoices in QuickBooks Online.
