Builds a balance sheet roll-forward schedule that shows how an account moves from beginning to ending balance, broken down by additions, accruals, reversals, payments, and adjustments. Each line ties back to a specific GL query or source document, and the whole thing must foot or it surfaces the unexplained delta instead of hiding it. Useful for month-end close packages and audit support when you need to explain exactly where every dollar came from. The structure is standard accounting reconciliation work, but having it automatically pull from GL and verify the math saves the manual tie-out grind.
