Customizing statements in QuickBooks Online (QBO) is a bit different from customizing invoices, Michael. Let me share some details with you.

Currently, statements in QBO don't offer the same level of customization as invoices. However, you can display each transaction on a separate line and include an aging table at the bottom. Here's how you can do it:

1. Go to the Gear icon at the top of your QBO account.
2. Select Account and settings.
3. Go to the Sales menu.
4. Click anywhere in the Statements section to open its contents.
5. Choose the option you want (List each transaction as a single line, List each transaction including all detail lines, or Show ageing table at bottom of statement).
6. Select Save.
