How can I list all Accounts, Contracts and Tickets that have unbilled charges?

You can list all open balances for accounts/contracts/tickets by selecting QuickBooks Invoice from the Main menu. To do so, go to Main menu > File > New > QuickBooks Invoice.

In the QuickBooks Invoice dialog window, you can select to view all open balances at the Account/Contract/Ticket level. An open balance is the sum of all Billable Charges that haven't been billed yet.
