Quickbooks administrator keeps creating duplicated invoices in our system. Does anyone else have this issue?

Thank you for letting us know about the system that keeps creating duplicate invoices, @info1940. We're glad to help you fix it and share details on why this is happening to your company file.

We understand the importance of using the software without any issues. With that, let me share some troubleshooting steps to help fix it. 

In QuickBooks Online (QBO), the system automatically creates invoices and other transactions if you have enabled and set up recurring transactions. Also, if it is added through bank rules and from a third-party app, the transactions will be tagged as created by the System Administration. Please check those to verify or disable those features if it's causing the issue.

On the other hand, you can delete or void the duplicate invoice to completely erase it from your books. Let me guide you with the steps below:

1. Click the Sales menu and select Invoices.
2. Find and open the invoice you want to delete.
3. In the Invoice window, click More at the bottom.
4. Choose either Delete or Void, then click Yes to confirm.
