In QuickBooks Desktop, once you create a sales order, you have to manually create an invoice, @Business1217.
You need to link fulfilled sales orders to convert them into invoices. You mentioned that an invoice is automatically generated once the sales order is packed. Are you using a third-party app to auto-generate an invoice from a sales order? If none, this can be some data issue with your QuickBooks Desktop. Let's work on isolating this issue by using QuickBooks' built-in diagnostic and repair tools, which are known as the rebuild and verify data utilities. These utilities are designed to fix any potential data damage within the file and will provide notifications after the repair process.
- Go to File, then select Utilities and Rebuild Data.
- Choose OK. Follow the prompts to save a backup.
- Click OK once completed.
- Now, go back to File, then Utilities, and select Verify Data this time.
If QuickBooks doesn't find any issues with your data, click OK. However, if it does detect a problem, you'll be asked to either Rebuild Now or View Errors. In that case, choose Close and then follow the steps below.
- Locate and check the QBWin.log or QuickBooks.log files.
- Scroll to the bottom for the most recent Verify information.
- Find the line that contains the LVL_ERROR, then check the Top data damage errors in QuickBooks Desktop.

About another independent invoice automatically generated for Item A with an ordered quantity of 0, there is no instance that QuickBooks will create an invoice with a 0 quantity for the same order.
