Yes, once you've categorized a transaction in QuickBooks Online (QBO), you can easily view any attachments associated with it directly in the transaction details, Lisa. Let me guide you on how to do this:
- Navigate to the Transaction menu and select Bank transaction.
- Choose Go to bank register.
- Select the small gear icon.
- Check the box next to Attachments.
- Use the funnel icon to filter the transactions by expense and make sure it's clear.

This process will display a column showing all the categorized expense transactions that include attachments, making it simple to manage and review your financial information.
