๐ Module 1: Accounting Fundamentals Refresher
Master the core Canadian accounting principles essential for confident use of QuickBooks Online.
Strong fundamentals ensure accurate transaction classification, reliable financial reports, and CRA compliance.
1.1 Why Accounting Fundamentals Matter in QuickBooks Online
QuickBooks Online automates many tasks, but success depends on correct accounting logic.
Misclassifying transactions leads to inaccurate financial statements and incorrect tax filings with the Canada Revenue Agency (CRA).
Canadian Business Essentials:
- HST/GST Compliance: Tax handling varies by province (13% HST in Ontario, 5% GST + PST in BC, etc.)
- CRA Requirements: Maintain books and records for 6 years minimum
- Currency: All amounts in Canadian Dollars (CAD $)
- Bank Integration: Connects with RBC, TD, Scotiabank, BMO, CIBC, Desjardins
- Input Tax Credits (ITCs): Recover HST/GST paid on business expenses
Key Principle: Garbage In โ Garbage Out. Clean data = trustworthy reports.
1.2 The Accounting Equation
Assets = Liabilities + Equity
This equation must always balance. Every transaction affects at least two accounts.
Common Canadian Examples (CAD $):
- Purchase equipment $8,000 cash โ Assets: Equipment โ$8,000 | Bank โ$8,000
- Invoice $3,000 + 13% HST โ Assets: AR โ$3,390 | Revenue โ$3,000 | HST Payable โ$390
- Pay supplier bill $1,500 โ Liabilities: AP โ$1,500 | Assets: Bank โ$1,500
- Owner invests $10,000 โ Assets: Bank โ$10,000 | Equity: Capital โ$10,000
Correcting Classification Errors
Common Mistake: Recording $8,000 office supplies as Equipment (asset) instead of Office Supplies (expense)
Impact: Assets overstated $8,000, Expenses understated $8,000, Net income overstated $8,000
Correction (if last month is closed):
DO NOT reopen closed period. Post adjusting entry in CURRENT period:
Debit: Office Supplies Expense $8,000
Credit: Equipment $8,000

1.3 Accrual vs Cash Basis Accounting
QBO records transactions the same way โ you choose the view when running reports.

| Expenses |

Real-World Example
Scenario: Invoice client $50,000 on December 28, 2025. Client pays January 15, 2026.
Accrual Accounting: Revenue recognized December 2025 (when earned/delivered)
โข Dec P&L: $50,000 revenue
โข Dec Balance Sheet: $50,000 Accounts Receivable
โข Jan P&L: $0 revenue (already recorded)
Cash Accounting: Revenue recognized January 2026 (when cash received)
โข Dec P&L: $0 revenue
โข Jan P&L: $50,000 revenue

Same data, different view!
Key Differences:
- Cash basis matches actual cash flow, simpler for tax filing
- Accrual basis matches revenue with expenses (matching principle), shows true profitability
- Many Canadian businesses use accrual for management, cash for tax filing (if CRA-approved)
1.4 Chart of Accounts โ Organizing Transactions
Purpose: The Chart of Accounts organizes and categorizes all financial transactions systematically.
It determines how data flows into Balance Sheet and Profit & Loss reports.
Five Main Account Types:
- Assets (what you own): Bank, Accounts Receivable, HST Receivable (ITCs), Equipment, Inventory
- Liabilities (what you owe): Accounts Payable, HST Payable, Credit Cards, Payroll Liabilities (CPP, EI)
- Equity (owner's interest): Owner's Capital, Retained Earnings, Drawings
- Income: Sales Revenue, Service Income, Interest Income
- Expenses: Rent, Salaries, Office Supplies, Utilities, Depreciation
Sample Canadian Chart of Accounts
ASSETS
1010 Bank - RBC Chequing
1200 Accounts Receivable
1300 HST Receivable (ITCs)
1700 Equipment

LIABILITIES

3100 Owner's Drawings
INCOME

4100 Service Income
EXPENSES

6900 Salaries & Wages
1.5 Double-Entry Bookkeeping โ Debits and Credits
Every transaction has equal debits and credits. Total debits always equal total credits.

โข Equity (Owner's Capital, Retained Earnings)
โข Accumulated Depreciation (contra-asset)
Accounts with DEBIT Balances:
โข Assets (Bank, AR, Equipment, HST Receivable)
โข Expenses (all expense accounts)
โข Owner's Drawings (contra-equity)
Transaction Examples with HST
1. Customer Invoice ($2,500 + 13% HST)
Debit: Accounts Receivable $2,825
Credit: Service Income $2,500
Credit: HST Payable $325
2. Office Supplies Purchase ($1,000 + 13% HST)
Debit: Office Supplies Expense $1,000
Debit: HST Receivable (ITC) $130
Credit: Bank $1,130
3. Rent Bill (no HST)
Debit: Rent Expense $3,500
Credit: Accounts Payable $3,500
1.6 Trial Balance and Error Detection
A Trial Balance lists all accounts with their debit or credit balances. Total debits must equal total credits.
Trial Balance Can Still Balance With These Errors:
- Double-posting: Transaction entered twice (both debit and credit duplicated)
- Wrong account: Office Supplies coded as Equipment (both debits, balance maintained)
- Classification error: Revenue recorded as liability (credits balance)
- Complete omission: Entire transaction missing (debit and credit both absent)
- Offsetting errors: Two errors canceling each other out

1.7 Reconciled Transactions โ Critical Rule
NEVER Delete Reconciled Transactions
Consequences of deleting:
โข Breaks reconciliation integrity
โข Creates discrepancies in financial reports
โข Makes future reconciliations impossible
โข Violates CRA audit trail requirements
โข Could indicate fraud or poor record-keeping
Correct approach:
โข VOID the transaction (preserves history)
โข Create adjusting journal entry in current period
โข Add detailed memo explaining correction
โข Attach supporting documentation
QBO Warning Example
โ ๏ธ This transaction has been reconciled
Deleting will cause:
โข Reconciliation to become unbalanced
โข Discrepancies in financial reports
โข Audit trail issues
Recommended: VOID instead of DELETE
[Cancel] [Void Transaction] [Delete Anyway]
โ Always choose VOID
1.8 Prepaid Expenses and the Matching Principle
Prepaid expenses are assets that become expenses over time. Properly allocate costs to match the periods benefited.
Example: Annual Insurance
January 1: Pay $12,000 for annual insurance
Initial Entry:
Debit: Prepaid Insurance (Asset) $12,000
Credit: Bank $12,000
Monthly Adjustment (each month-end):
Debit: Insurance Expense $1,000
Credit: Prepaid Insurance $1,000
Memo: "Monthly insurance expense (1/12 of annual)"
Month-by-Month Impact
| Date |
Prepaid Insurance |
Monthly Expense |
| Jan 1 |
$12,000 |

| Jan 31 |

$1,000 |
| Feb 28 |
$10,000 |
$1,000 |
| Dec 31 |

$1,000 |
Why adjust monthly? To match the expense with the period it benefits, giving accurate monthly profitability.
