I would like to be able to choose which business the receipt is filed under.
You can set up two policies for expenses. One for one company and one for the other company. Each expense or report you can decide what policy it goes under. The different policies can sync with different quickbooks accounts or whatever you use. I would take a deep look at expense policies and start there. You may have some unique situations that will require some workarounds, but really it's one of the strong points of the engineering behind Expensify to allow this sort of behavior.
