I can not make invoice or estimates

It's nice to have you here in the Community, fggraniteandmarb.

I can help you make invoices or estimates in QuickBooks Online (QBO).

To verify, did you encounter an error while trying to make an invoice or estimate? If yes, can you tell me the exact error? This will help me narrow down the cause of the issue.

If not, we can perform some basic browser troubleshooting. The stored history on your regular browser may have been corrupted thus preventing you from making invoices and estimates. Let's switch to a different browser and try it one more time.

You can refer to the following keyboard shortcuts below:

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

Then, try creating an invoice or an estimate again. If this works in a private browser, you can clear the cache or delete temporary internet files from your regular browser. That'll remove previously-stored browsing data that might have caused the issue. Here's a complete guide on how to do that: How Do I Clear My Browser Cache And Temporary Internet Files?  

Otherwise, you can try other supported browsers to further isolate the issue.
