Hi @laurent-perraud,

Currently, you can only delete a single line item at a time in a bill.

However, you can click the Clear all lines or the Clear button to restore a bill back to the original form.

You can also share this with our developers by sending feedback. This will be a good option for future updates. Just go to the Gear icon then select Feedback.

Please let us know if you have any other questions. We're always here to help.
