Thanks for providing details about your concern, @CP-.
Currently, the option to consolidate your billable expense into one particular line item is unavailable. As a workaround, you can consider using a third-party application to achieve this option in the new invoice layout. Head to the QuickBooks App Store to find apps that integrate with QuickBooks Online.
I understand how beneficial this feature is to your business as it helps shorten the list to only the total amount when billed to your customers. With this, I recommend you send your feedback directly to our product developers so they can review your suggestions and may include the feature enhancement in the following updates. Here's how:
- Go to the Gear icon.
- Under the Profile column, click on Feedback.
- Type in your feature request.
- Click Next to submit.
