Thanks for joining the thread, Sirenna.

You should be able to see the Sales tab on the Account and Setting page. Let's perform some troubleshooting to isolate the issue. It could be that the calculated site data in the browser is the root cause of this unusual behavior. Use these shortcut keys to open your QBO company using a private window:

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

If you can now see the progress invoicing feature, you'll have close the incognito mode and go back to your main browser. After that, clear its cache to start over fresh. You may also switch to other supported web browsers.

Additionally, take note that this functionality isn't available yet in the updated UI. If you see “New” beside the form title, you’re currently using the latest design.

You'll want to switch to the old experience to use this option. Here's how to do it:

1. Click the + New button.
2. Choose Invoice or Estimate.
3. Select Old layout.
