Invoice to bill customer for the billable expenses , Is there a option to reclass the billable expenses back to the existing accounts instead of the bill income account

Hi there, merit.

When setting up billable expense in QuickBooks Online (QBO), the system automatically create and assign a default income account. Currently, the option to change it is unavailable.

We'd love to hear your inputs. I recommend leaving feedback to notify our engineers about the feature you need. This way, they can consider adding it in the future updates. Here's how to submit feedback:

1. In QBO, go to the Gear icon at the top, then Feedback.
2. Enter your comments or product suggestions. Then select Next to submit feedback.

To know more about managing and entering billable expenses in QBO, check out this article: Enter billable expenses.

In case you want to remove a billable expense charge, you can refer to this article for future reference: Remove a billable expense charge in QuickBooks Online.

Please let me know if you have follow-up questions about this or anything else. I'll be more than willing to assist. Take care.
