Choose a date range and accounting method for Trial Balance Period Difference. Starting is the balance before the period; Ending is the balance at its close.

The Period column is Ending minus Starting. Click the Business Checking movement to see the transactions that explain the change.

The drill lists the period transactions and checks debit minus credit against the movement you clicked. Follow the linked details as you investigate.

Turn off Single Column Debit-Credit for separate starting, period, and ending debit and credit columns. Switch it back on for the compact three-column view.
