Let's work together, Iris. To determine how to identify missing transactions.
To check for any missing attachments in your transaction, follow the steps below:
- Click Sales on the left panel.
- Select the All Sales tab.
- Click the Gear icon beside the ACTION column.
- Tick the Attachments box.
If you want to add an attachment to a transaction, edit the transaction, then click on the attachment button, choose the file to upload, and then select Open. You can also export the list so you can have a better view of the sales transactions that don't have attachments.
Also, I'm adding this article to help you get the most out of your financial reports: Customize reports in QuickBooks Online.
