Ok! This is SO absurd, but I figured out how to get billed expenses to show up-- and it has nothing to do with caches or anything of the sort. You simply click on "Create Invoices" and then type in the Customer Name. Once it does, click on the little clock button next to the Template Type in the second bar from the top (circled in the picture.) Yes! When the window first pops up it's blank because it defaults to the "Time" tab, but then click on the "Expenses" tab next to it and, voila!, all of the reimbursable expense show up.
I just switched from desktop to QBO essentials. I don't want the billable tracking but a few employee payments were marked billable. How can I remove the billable checkmark now that I am using essentials?
