Let ChatGPT explain the finance close only after the numbers reconcile

The dangerous finance-close answer is not obviously wrong.

It is a polished explanation built from numbers that were never reconciled.

A ChatGPT database query can help investigate a variance. But month-end close is a controlled process, not an open-ended conversation with live tables.

Before the model explains anything:

  • freeze the entity, ledger, period, currency, timezone, and cutoff
  • bind words like revenue to an approved metric version
  • reconcile subledgers and control accounts deterministically
  • classify duplicate, late, reversed, and unposted entries
  • return bounded exception groups instead of a giant export
  • keep source, snapshot, filters, totals, and trace ID separate from the prose

If a reconciliation check fails, return an exception—not a narrative that rationalizes the difference.

The model may summarize the work. It should not become the system of record.

That distinction makes the workflow useful: analysts get a fast explanation, while reviewers can still reproduce the evidence without trusting the wording.
