How do I send a completed invoice?

I'm here to help you sort this out, johneayrs3-gmail.

There are times that the saved data in the browser's cache will become outdated over time and will cause odd behavior to the program. I'd recommend performing the browser troubleshooting method to fix this.

Here are the shortcut keys to access an incognito browser:

• Safari: Hold down ⌘ + Option + P
• Google Chrome: Ctrl + Shift + N
• Microsoft Edge & Mozilla Firefox: Ctrl + Shift + P
  
  

Let's begin with using a private browser when logging into QuickBooks Online. Then, create a test invoice and select the option Save and Send. If a new blank Invoice window appears right after clicking that option, you can go back to the regular browser and clear the cache. However, if it's not, you can use another supported browser as an alternative.
