Twelve papers. One useful question.

Fictional practice: match the exact entity and month, then keep the books-agree question separate. These excerpts are a teaching fixture, not Mat’s checklist or an actual accounting record.

Read the sources, copy the prompt to your chosen assistant, then compare its answer with the example. The example is kept out of the copied prompt. No account or X1 connection is needed.

harbor-september, page 1

Fictional bank statement for Harbor Property LLC. Period: September 1–30, 2025. This excerpt identifies the entity and period. It supplies no accounting reconciliation evidence.

cedar-october, page 1

Fictional bank statement for Cedar Operations LLC. Period: October 1–31, 2025. Cedar Operations LLC is a separate entity from Harbor Property LLC.

harbor-august, page 1

Fictional bank statement for Harbor Property LLC. Period: August 1–31, 2025. It is a different month from October.

Prompt with the fictional sources

        Using ONLY these fictional excerpts, prepare two evidence rows for
        Harbor Property LLC: September 2025 and October 2025. Give the exact
        entity, period, source/page and what the excerpt establishes. Keep
        evidence status separate from accounting reconciliation. Say not found
        in these supplied excerpts if nothing matches; do not conclude global
        absence. A different entity or period cannot satisfy a row. Draft the
        first useful question for the bookkeeper. Do not post entries,
        reconcile, save or send anything. FICTIONAL SOURCE EXCERPTS [ {

Compare with an example answer

Harbor · September 2025: Entity and period identified by harbor-september, page 1. Reconciliation remains unverified.
Harbor · October 2025: Not found in the supplied excerpts. Cedar's October and Harbor's August do not satisfy this row. This does not prove the file is absent elsewhere.
A first question: Do you have Harbor's October 2025 statement, and the accounting reconciliation evidence for these periods?
