## Direct answer

Use ChatGPT Work to assemble a reconciliation review packet from a named, read-only population: tie source documents to ledger rows, recompute amounts, preserve native identifiers, and label each difference as a timing question, missing evidence, duplicate, coding candidate, or calculation exception. A difference is not a correction, and a balanced worksheet is not proof that the books are right. ChatGPT must not choose accounting treatment, create or reverse a journal, change a code, clear a reconciliation, or certify a close. The attached figures are projected role-task priors, not measured ChatGPT adoption by bookkeeping, accounting, and auditing clerks, so they support a controlled review trial rather than a claim about current practice.

## Best uses

- Check figures, postings, and documents for correct entry, mathematical accuracy, and proper codes.
  - Artifact: Review worksheet listing mismatches, evidence, and proposed corrections
  - Review: Verify against source documents and approve or reject each correction.

## Workflows

### Turn approved transaction exports and source documents into a reconciliation review packet.

Steps: Confirm the period, entities, currencies, and source completeness. → Match records and calculate variances without writing to the accounting system. → List exceptions with source references and proposed explanations. → Produce a reconciliation packet for clerk and controller review.

Artifact: Reconciliation worksheet and exception log

Human review: A qualified person verifies calculations and authorizes every correction or posting.

## Human-owned responsibilities

- Population law: the responsible accountant confirms the entity, period, currency, completeness, and authoritative source population before any comparison
- Evidence law: a source row, statement line, or supporting document may establish a fact only at its stated date and scope; missing evidence and timing differences remain open states
- Treatment law: account coding, cutoff, materiality, accrual, reversal, and explanation of a variance require qualified accounting judgment
- Posting law: journal preparation, approval, entry, correction, reconciliation sign-off, and close certification remain controlled human actions with segregation of duties
- Record law: source documents, working papers, exception disposition, and review evidence remain retained in the accounting record under the applicable retention policy
