What Are Accounting Entries (In Simple Terms)
Accounting entries are the foundation of bookkeeping. Every financial transaction, from sales and expenses to payroll and taxes, is recorded as a debit and a credit in your books. This is called the double-entry system, ensuring that your books stay balanced. But don't confuse it with debit or credit in a bank statement. Debit and credit have different meanings in the accounting world.
Core Accounting Entries Every Small Business Needs
- Sales and Revenue Entries: Record all sales transactions correctly, including cash sales, credit sales, and HST collected. It is important to understand when revenue is recognized as per accounting standards. Collecting actual money may not be equivalent to revenue.
- Expense and Purchase Entries: Enter all business expenses with accurate categories, avoid using 'miscellaneous' accounts. Again, like revenue, making a payment is not essentially linked to recording an expense when following the accrual basis of accounting.
- Payroll Entries: Include wages, CPP, EI, and income tax deductions along with employer contributions.
- HST Entries: Track HST collected on sales and HST paid on expenses to ensure accurate filing. Keep HST/GST collected separate from your revenue; it is not your money.
- Bank and Credit Card Entries: Regularly reconcile deposits, transfers, and payments to avoid discrepancies.
Adjusting Entries (Year-End)
An adjusting entry is a journal entry made at the end of an accounting period to update account balances before preparing financial statements. These ensure your books reflect real financial performance.
It ensures that revenues and expenses are recorded in the correct period; for example, recognizing unpaid expenses (accruals) or spreading prepaid costs (such as rent or insurance) over time.
If you prepaid $6,000 for a one-year insurance policy on January 1, you would record an adjusting entry each month for $500:
Debit Insurance Expense $500
Credit Prepaid Insurance $500
This way, your books show only the portion of the insurance used during the period.
Year-end Closing Entries
Closing entries are journal entries made at the end of the fiscal year to transfer temporary account balances; such as revenues, expenses, and drawings, into permanent accounts like retained earnings or owner's equity.
They reset the income statement accounts to zero so the next year's bookkeeping starts fresh.
If your business earned $80,000 in revenue and incurred $60,000 in expenses, you would record a closing entry to transfer the $20,000 net income:
Debit Revenue $80,000
Credit Expenses $60,000
Credit Retained Earnings (or Owner's Capital) $20,000
Additional Key Points Every Small Business Owner Should Understand
1️⃣ Not everything coming into your bank account is income and not everything leaving is an expense.
Bank deposits might include things like owner contributions, loan proceeds, or tax refunds, which are not taxable income. Similarly, payments leaving the account could be asset purchases, loan repayments, or personal drawings, not deductible business expenses. That's why relying on bank transactions alone without proper accounting classification can seriously distort your financial statements.
2️⃣ Understand whether you're doing accounting on a cash basis or an accrual basis and what that means.
Cash basis recognizes income and expenses when cash changes hands. Accrual basis records income when earned and expenses when incurred, regardless of payment. Most incorporated businesses and CRA filings require accrual accounting, which gives a more accurate picture of financial performance.
3️⃣ Know the underlying basis and standards guiding your accounting.
Accurate records depend on consistent accounting principles, such as your depreciation method, asset valuation, and how you report bad debts or accounts receivable. Choosing and applying these standards correctly affects your net income, balance sheet strength, and even tax obligations.
Common Mistakes Small Businesses Make
- Mixing personal and business expenses
- Ignoring HST reconciliation or claiming incorrect input tax credits
- Using wrong account categories in QuickBooks
- Missing adjusting entries at year-end
- Not reconciling bank accounts monthly
Relying on accounting software alone without understanding accounting principles can give a false sense of accuracy. Your reports might look neat, but they can still be wrong, leading to missed deductions and possible CRA penalties.
Can Accounting Software Handle It All?
Many business owners believe that using QuickBooks, Wave or other accounting software means their accounting is 'handled'. Unfortunately, that's one of the biggest misconceptions. Accounting software records data, it doesn't interpret it, and one still needs accounting knowledge. That's why every business still needs an accountant, whether internal or external.
Without knowing how to treat each transaction, classify expenses, or handle HST/GST properly, you can end up with distorted reports. At Source Accounting, we regularly fix books that looked 'perfect' in QuickBooks but were completely off. Once your books are set up properly, these tools become powerful allies, not potential traps.
When It's Time to Call a Professional Accountant
You should reach out to an accountant when:
- You receive CRA letters or HST/GST filing notices
- When your books reflect more income than your business truly made or the opposite
- Your accounts don't reconcile
- You can't match HST/GST collected vs. HST/GST paid
- Year-end is approaching, and your books aren't up to date

Real-World Example: How We Fix Messy Books
A Mississauga café owner came to us with unreconciled HST and incorrect expense categorizations spanning 26 months. Even though they were using reputable accounting software, their books were unreliable, and they couldn't trust their own financial reports. Lacking proper accounting knowledge, they knew something wasn't right — and eventually, the CRA began making calls and sending collection notices. We cleaned up their books, corrected the filings, and recovered missed deductions. Afterward, their financial reports were accurate, their CRA issues were resolved, and they regained full confidence in their numbers.
At Source Accounting Professional Corporation, we help business owners avoid this exact situation, by ensuring their bookkeeping is accurate, compliant, and ready for real decision-making.
