The Monthly Source Check

Review this minimized monthly summary against the source excerpts I provide. For each amount, list its date, category, source and whether it is confirmed. Separate actual entries from estimates and plans. Flag duplicates, transfers counted twice, missing periods and arithmetic mismatches. Leave unsupported amounts unresolved. Do not treat a credit limit or expected payment as money received.

Keep a number tied to the record it came from. This worksheet checks the information in a monthly summary before you rely on it.

Your next check

Recalculate the supplied category totals from confirmed rows only. Show the arithmetic. List excluded estimates and unresolved entries separately so I can check them against the originals.

A summary says 250 was received, but the source only shows an expected payment. Mark 250 as expected and unconfirmed. Do not add it to confirmed receipts. This is a record-checking example, not a statement about your available balance.

Bill extraction: keep the due date tied to its source

Using only the messages below, identify bills. For each bill, return supplier, amount, due date and any stated late-fee terms. Quote the exact source sentence supporting each due date and fee term, and identify which message it came from. If a message has no bill, put it in a separate “No bill found” section. If a bill has no stated due date or fee term, mark that field “Not stated”. Do not infer missing dates, set reminders, make payments or send anything.

Use this on supplied bill text or minimized message excerpts. Keep account details and unrelated personal information out of the input. This exercise extracts information; it does not monitor your inbox or execute reminders. The Monthly Source Check above is a separate exercise for verifying a monthly summary.

How to use it

  1. Minimize before sharing

    Prefer a manually prepared table with dates, categories, amounts and source labels. Omit account/routing/card numbers, names, addresses, login details and transaction descriptions that are not needed.

  2. Redact source copies

    If an approved PDF excerpt is necessary, apply real redaction and remove hidden information. Reopen the copy and check that removed text cannot be searched or copied. Keep the original private.

  3. Trace each amount

    Record: date | category | amount | source label | actual or estimate | verification. Compare totals independently and keep transfers distinct from new income.

  4. Resolve before relying

    Investigate mismatches using your original records. Mark missing support as unresolved rather than guessing available funds. Keep credentials out of the prompt.

  5. Check the bill extraction

    Compare each amount and due date with its quoted source. Keep missing dates and unstated fee terms unresolved; do not treat them as confirmed. Decide what to do yourself. This exercise extracts information; it does not monitor your inbox or execute reminders.
