Why are bills not showing in my QuickBooks reports?

The transaction detail reports that can be ran from inside Filevine are generated on an "accrual basis". This is to ensure the total case cost balance is syncing to Filevine (i.e. case cost balances include unpaid bills). When you run your reports in QuickBooks Online, you can toggle the report to "accrual," and you will see unpaid bills included as well.
