I understand the challenges you're facing when you only want to invoice for specific line items from an estimate in QuickBooks Online (QBO), Mdmx.
Currently, this option is unavailable in QBO. As a workaround, you can create a new estimate specific to that item.
I can see how the functionality to edit your remittance slip would be beneficial to your business. I'd recommend sending a feature request directly to our Product Development team. This helps us improve your experience and the features of the program.
Here's how:
- Go to the Gear menu and then select Feedback.
- Type in your feature request in the description box.
- Once done, click on Next.

You can also track feature requests through the Customer Feedback for QuickBooks Online website.
