Has quickbooks undergone an upgrade? I seem to be unable to set up an invoice directly in QB. It is asking me to upload an invoice instead.

Hi there, @treasurer91.

Thanks for coming to the Community. We haven't received updates about QuickBooks being upgraded. We only have reported issues about being unable to create an invoice in QuickBooks Online. 

At the moment, our engineers are now working to identify the cause to fix the issue. 

At this point, I'd recommend contacting our Customer Support team. Let them know you want your account linked to the INV-46408. This way, you'll receive updates via email. 

You can also upload your invoice to QuickBooks Online Advanced. Learn more about it by reading through this article: Import multiple invoices at once.

Here's another article that can help you learn about how to let your customers pay their invoices online: Send online invoices in QuickBooks Online.

Feel free to come back should you need more support. We're always delighted to assist you further.
