I am not able to create new invoice

Hi there, @info-skyhightrav.

Thank you for raising your concern here on the Community page. I'm here to help you today and ensure you'll be able to create a new invoice successfully.

To get started, may I know the specific error message you've got when trying to record an invoice? This way, I'll be able to gather enough information and check for any open investigation about the issue.

For the time being, I recommend performing these troubleshooting steps to isolate this unusual behaviour.

First, open QuickBooks using a private browser. Sometimes, the regular browser tends to hold onto information, and over time it could cause problems while working with QuickBooks.

To save you time, use either of these keyboard shortcuts:

• Google Chrome: Ctrl + Shift + N
• Safari 11 or newer: ⌘ + Shift + N
• Mozilla Firefox: Ctrl + Shift + P
• Microsoft Edge: Ctrl + Shift + P

If you're able to enter a new invoice, go back to your original browser and clear the cache to start fresh. 

Or, use an alternative browser when opening QuickBooks.

As additional resources, while managing invoices or sales transactions in QuickBooks, you can check out the details from this link: Create invoices in QuickBooks Online.

If you wish to personalise your invoices in the future, here's an article you can use as a guide: Customise invoices, estimates, and sales receipts in QuickBooks Online.

I'm looking forward to hearing from you again. If you have any other QuickBooks questions, please feel free to add a comment below. Thanks for coming, keep safe always!
