Bookkeeping mistakes cost money—missed deductions, CRA penalties, and poor business decisions based on inaccurate data. Here are the most common errors and how to avoid them.

❌ Mistake #1: Not Reconciling Bank Accounts

Many business owners skip bank reconciliation. This means errors, duplicate entries, and fraud can go undetected for months.

❌ Mistake #2: Mixing Personal and Business

Using personal accounts for business or vice versa creates a mess. CRA auditors look closely at this.

Solution: Separate accounts, separate cards, always.

❌ Mistake #3: Not Keeping Receipts

CRA can deny deductions if you cannot produce receipts. "I know I bought it" is not proof.

❌ Mistake #4: Wrong Expense Categories

Putting expenses in wrong categories distorts your financial reports and can cause tax issues.

• Meals are 50% deductible—do not put in general expenses
• Capital purchases are not fully deductible in year one
• Owner draws are not expenses

❌ Mistake #5: Ignoring Accounts Receivable

Recording sales but not tracking who owes you leads to lost revenue. Send invoices promptly and follow up.

❌ Mistake #6: Procrastinating on Bookkeeping

Waiting until year-end to do bookkeeping means:

• Forgotten transactions
• Lost receipts
• Rushed, error-prone work
• Higher accountant fees

❌ Mistake #7: Not Backing Up Data

If your computer crashes or software fails, you need backups. Cloud accounting software handles this automatically.
