Problem

You are given a month-end reporting workflow that currently relies on manual spreadsheet cleanup. Write a PostgreSQL query that returns each active account’s month-end billed amount for a chosen reporting month, using only posted transactions and excluding voided items. The result should be sorted by highest billed amount, then account name.
