Hello there! Let me help you with some insights on why you might not be able to view the Create Invoice option and the workaround to locate unpaid invoices in QuickBooks Online (QBO).
Normally, the system displays the Create Invoice option and unpaid invoices under the Sales menu in QBO. However, if you are experiencing issues contrary to what you should be able to view, I recommend performing browser troubleshooting, which includes clearing cache and cookies to fix issues when using QuickBooks Online.
If you wish to check your outstanding invoices that have not been paid yet, you may follow the steps given below:
Go to the Sales menu.
Select the Invoices tab.
Choose Unpaid on the dropdown▼ under the Status column.
Additionally, you can also pull up the Open Invoices report to generate all unpaid invoices you made within your book. To do this, go to the Reports menu and type in Open Invoices in the search option. You can find detailed instructions on how to customise reports in QuickBooks Online in the outlined article.
