Getting a query processing error? Won’t let me make invoices.

It's nice to see you here, TKtruck18. 

 I'm here to help you create an invoice successfully in QuickBooks Online.

There are times that your default browser is filled with data and temporary files from previously visited websites. With this said, I recommend using a private browser. Doing so helps isolate the issue. You can use the keyboard shortcuts below:

• Press Ctrl + Shift + N (Google Chrome).
• Ctrl + Shift + P (Firefox).
• Control + Option + P (Safari).

Once you've opened a private browser, try to create a new invoice again. You can also use another supported browser to open your account and save your transaction. This might be a temporary issue with QuickBooks and the current browser you're using.

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.

Also, there are several financial reports you can run to track your sales income in QuickBooks. They will show you helpful insights on the things you buy and sell, and the status of your inventory.

You're always welcome to post any questions you have in this space related to invoices. I'll be happy to help you some more. Have a good day.

I’m getting the same. It is letting me invoice, but the error keeps popping up and I cannot access my estimates.
