Bookkeeping Basics
Understand why every bookkeeping entry has two sides and why debits and credits are not simply good or bad.
Best for: owners who want to understand the idea behind entries without becoming accountants.
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.
Debits and credits are the left and right sides of accounting entries. They are not automatically good or bad, and account type matters.
What this means
Every transaction affects at least two accounts. Debits and credits keep the accounting equation in balance.
Even when software handles entries, the concept helps you understand transfers, loans, payroll entries, owner activity, and corrections.
Core concepts
A business event usually affects more than one account.
A debit can increase some accounts and decrease others depending on account type.
Total debits and total credits in an entry should balance.
Manual adjustments need strong support and review.
Step-by-step workflow
- Gather the source records. Save statements, receipts, reports, screenshots, contracts, confirmations, or notes that support debits and credits.
- Identify the business event. Decide what actually happened before choosing a category or changing a report.
- Match the money movement. Compare the bookkeeping record to bank, credit card, loan, payroll, or platform activity.
- Choose the right treatment. Separate income, expense, asset, liability, equity, transfer, and owner activity instead of using one catch-all category.
- Review for duplicates and timing. Look for repeated entries, missing transactions, old balances, refunds, chargebacks, and period cut-off issues.
- 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.
