Welcome to the Community, @qbo-cust-mega-se.
Exporting the actual bill transaction is currently unavailable. But I have a workaround you can consider.
You can pull up and export the Transaction Journal of your bill. This way, you’ll view the same data on the actual bill. Here’s how you can pull up the transaction journal:
Then, you can click on the Export button to either Export to Excel or Export to PDF.
You can refer to this article for more details: Export Your Reports to Excel from QuickBooks Online.
Please let me know if you have other questions or concerns. I’ll only be a post away.
