Thank you so much for the feedback. I do not see the billable options in my settings, so I don't know if it is because I am in the accountant version or the client doesn't have the correct version that allows for billable options. I attached a screenshot of my settings.

I did test out the $0 invoice theory though and that seems to work. I just had to add a line item for $0 to create the invoice and clear out the billable charges.
