Do you know how this works for QBO? I do not have the option to Hide. I tried adding all the billable expense to the invoice, then clearing the lines of the invoices and selecting the option to no, keep them when the question "would you also like to unlink the billable items" appears. Looks like this will remove the billable expenses, but QBO won't let me save a $0 invoice so I'm not able to complete my process.

I should also mention that I do not have the option to uncheck a billable box. I navigate to the billable transaction in question and there is no billable box. I've check my account settings on QBO, but I do not see any settings to "mark all checks as billable."
