I'm glad you found a workaround to your concern, @captrwbristol.

I understand that running the Transaction List with Splits report doesn't provide all the line details of a bill. However, this is the best way to export the line details of your bill.

I can see that an export option on the Bill page is beneficial for you and your business. For now, I suggest submitting your feedback directly to our product engineers. They may look into this suggestion and consider adding the option in the future update. To send feedback, you can go to the Gear icon and select Feedback. Then, enter your suggestion and click Submit.

Our doors are always open to help you again if you have any other concerns or follow-up questions. Wishing you all the best, @captrwbristol.
