Hi there, @ncarty97. 

The Add All option for billable expenses is unavailable in the new invoice template. I understand the benefit of this feature to streamline or handle your invoice templates efficiently. For now, you can switch back to the old invoice layout to access that option.  

Here's how:

1. In the + New button, select  Invoice.
2. On the upper left corner, click Old layout.
3. Then select Switch layout.

I recognize your need for this feature so I recommend sending feedback to our development team. This way, they can review your suggestion and consider it for the next product enhancements.

Here's how:

1. Select the Gear icon, then choose Feedback.
2. Type in your comments or product suggestions.
3. Select Next to submit.

If you've already paid for a business expense, you can check out this article to help you with the process: Enter and manage expenses in QuickBooks Online.

Please feel free to reach out again if you have any follow-up concerns. I'll be here to help.
