Best for: anyone who wants future reviewers to understand why numbers were entered or changed.

Important: This article is general bookkeeping education. It is not tax, legal, payroll, or accounting advice. Rules and correct treatment can depend on entity type, industry, location, software setup, and professional judgment.

Quick answer

Good notes explain what happened, why it was categorized that way, what source was used, and what still needs follow-up.

What this means

Bookkeeping notes preserve context for transactions, monthly close files, templates, reports, and adjustments.

A number without context can create questions. Notes help the owner, bookkeeper, accountant, or future reviewer understand the decision.

Core concepts

Transaction notes

Explain unusual deposits, expenses, refunds, transfers, and adjustments.

Monthly notes

Summarize what changed during the period.

Question notes

Track missing support and unresolved categorization.

Professional notes

Record instructions from tax, payroll, or accounting advisors.

Step-by-step workflow

  1. Gather the source records. Save statements, receipts, reports, screenshots, contracts, confirmations, or notes that support bookkeeping notes and explanations.
  2. Identify the business event. Decide what actually happened before choosing a category or changing a report.
  3. Match the money movement. Compare the bookkeeping record to bank, credit card, loan, payroll, or platform activity.
  4. Choose the right treatment. Separate income, expense, asset, liability, equity, transfer, and owner activity instead of using one catch-all category.
  5. Review for duplicates and timing. Look for repeated entries, missing transactions, old balances, refunds, chargebacks, and period cut-off issues.
  6. Save final notes. Keep a clear explanation so the owner, bookkeeper, or accountant can understand the decision later.

Review checklist

  • The period, account, and source report being reviewed are clearly identified.
  • Transactions are not duplicated or counted in the wrong period.
  • Unclear items are placed on a question list instead of guessed.
  • Supporting documents are saved in the monthly records folder.
  • The final report or template includes notes for unusual activity.

Common mistakes to avoid

  • Guessing from the bank description only. Bank descriptions are helpful but often incomplete.
  • Using miscellaneous too often. Too many miscellaneous entries make reports less useful.
  • Skipping documentation. A correct number is harder to defend when the source is missing.
  • Ignoring balance sheet effects. Some activity affects assets, liabilities, or equity rather than the P&L.
