My workaround was to create an email address just for company receipts, in gmail, and use labels to apply accounts to expenses, then all of the receipts and accounts are in the same place, and it's super easy for the accountant to enter the bills.  Entering an item for every expense is way too time consuming.  The email method is great for tracking all receipts, and I use that email as a login for every vendor so the receipts always go there, and my service writer and accountant can log into everything using that email instead of mine, or their own email which I don't access to.  

@Ryan_MQuickbooks online has the ability to enter expenses into a purchase order, so the reasoning that it being non posting as to why the feature is not available is not an adequate excuse.  the only reason it is not available on desktop is that the QuickBooks team doesn't care enough to make it happen.
