Bookkeeping Terms Explained
for Business Owners
Every Canadian business owner reviews financial reports, signs off on tax returns, and communicates with their bookkeeper or CPA — but most do so without fully understanding the terminology. This plain-language guide explains every essential bookkeeping and accounting term you'll encounter as a business owner, organized by category with real-world examples. No accounting degree required. Understanding these terms helps you make better business decisions, catch errors faster, and have more productive conversations with your financial team.
1. Why Understanding Bookkeeping Terms Matters
Most Canadian small business owners run their business successfully for years while only partially understanding the financial language their CPA and bookkeeper use. They know "revenue is good" and "expenses are bad" — but when words like "accrual," "deferred revenue," "amortization," or "working capital" come up in a conversation, many owners mentally switch off and defer to the expert. This is a costly habit.
Understanding bookkeeping terminology means you can review your monthly reports with confidence, identify errors or anomalies before they become problems, ask the right questions during tax planning meetings, and make more informed strategic decisions. You don't need to be able to prepare financial statements — but you do need to be able to read them. Our Monthly Bookkeeping Report Guide shows how these terms appear in your actual monthly reports, and our guide on DIY vs. Professional Bookkeeping explains which of these functions you can manage yourself and which require professional expertise.
This glossary is organized by the context in which you'll encounter each term — so when you're reviewing your income statement, you can find all income statement terms in one place. For payroll-specific terminology, our Payroll Tax Compliance Checklist explains every payroll deduction term. For manufacturing tax terms, see our Tax Services for Manufacturing guide.

2. Income Statement Terms — Your Profit & Loss Report
The Income Statement (also called a Profit & Loss statement or P&L) shows what your business earned and spent over a period of time. Here is a sample P&L with every line item explained:
All money earned from selling products or services before any costs are deducted. Also called "sales" or "top line."
The direct costs to produce or deliver your product or service — raw materials, direct labour, freight in. Does NOT include overhead like rent.
Revenue minus COGS. The money available to cover overhead and generate profit. Gross Profit ÷ Revenue = Gross Margin %.
All costs to run the business beyond COGS — rent, salaries, marketing, insurance, utilities, professional fees. Fixed or variable but not direct production costs.
Earnings Before Interest, Taxes, Depreciation, and Amortization. A common measure of operating profitability that strips out financing and accounting adjustments.
A non-cash expense that spreads the cost of a long-term asset over its useful life. Depreciation = physical assets; Amortization = intangible assets. In Canada, the tax equivalent is CCA.
3. Balance Sheet Terms — What Your Business Owns and Owes
The Balance Sheet is a snapshot of your financial position at a single point in time. It follows the fundamental equation: Assets = Liabilities + Equity. Every transaction your business makes keeps this equation in balance.
Everything your business owns or is owed that has economic value. Divided into current assets (converted to cash within 12 months) and non-current assets (long-term).
Money that customers owe you for work completed but not yet paid. It's an asset because it represents future cash you're entitled to collect.
Goods held for sale (retail), raw materials and finished products (manufacturing), or work in progress. Valued at cost under Canadian accounting standards.
Expenses paid in advance that haven't been "used up" yet. The value that remains unexpensed is an asset on the balance sheet.
Everything your business owes to others — suppliers, lenders, government (taxes), employees (wages payable). Divided into current (due within 12 months) and long-term.
Money your business owes to suppliers and vendors for goods/services received but not yet paid. The opposite of accounts receivable.
The owner's residual interest — what's left after all liabilities are deducted from all assets. Grows when the business is profitable; shrinks with losses or owner withdrawals.
Accumulated profits that have been kept in the business rather than distributed to owners. Rising retained earnings indicate a healthy, profitable business over time.
4. Cash Flow Terms — Why Profit ≠ Cash
One of the most important financial concepts for business owners: profitability and cash flow are different — and a profitable business can run out of cash. Understanding cash flow terminology helps you manage this critical distinction.
The actual movement of money in and out of your business bank account. Unlike profit, cash flow only counts real cash transactions — not invoices sent or expenses incurred.
Current Assets minus Current Liabilities. The short-term financial cushion available to run daily operations. Positive working capital = healthy; negative = cash crisis risk.
Records revenue when earned and expenses when incurred — regardless of when cash changes hands. Most accurate for financial reporting; required for most incorporated businesses.
Records revenue when cash is received and expenses when cash is paid. Simpler but less accurate for matching income and expenses to the right period.
Cash received from customers for services not yet delivered. It's a liability — you owe the service. Once delivered, it becomes revenue.
Expenses incurred but not yet invoiced or paid — like wages earned in December but paid in January. Recorded to match expenses to the period they relate to.

5. Debits, Credits & the Accounting Equation
"Debit" and "Credit" are among the most misunderstood terms in bookkeeping — because they don't mean what most people think. In accounting, debit and credit simply mean "left side" and "right side" of the accounting ledger. Here's how they work:
| Account Type | Debit (DR) Effect | Credit (CR) Effect | Normal Balance |
|---|---|---|---|
| Assets (cash, AR, equipment) | ✅ Increases | Decreases | Debit |
| Liabilities (AP, loans) | Decreases | ✅ Increases | Credit |
| Equity (retained earnings) | Decreases | ✅ Increases | Credit |
| Revenue (sales) | Decreases | ✅ Increases | Credit |
| Expenses (rent, wages, COGS) | ✅ Increases | Decreases | Debit |
6. Tax & GST/HST Bookkeeping Terms
For Canadian businesses, tax-related bookkeeping terms are among the most practically important. For SaaS-specific tax terminology, see our SaaS Tax Planning Guide. For year-end financial reporting terms, see our Post-Compilation Follow-Up Checklist.
Goods and Services Tax / Harmonized Sales Tax — federal and provincial sales tax collected from customers and remitted to CRA. Not your revenue; it's a government liability held in trust.
GST/HST you paid on business purchases that you can recover from CRA by claiming it on your GST/HST return. Reduces the net amount you owe to CRA.
The Canadian tax system's version of depreciation — how the CRA allows you to deduct the cost of capital assets over time. Different asset classes have different CCA rates.
The Canadian corporate income tax return filed annually by corporations. Due 6 months after fiscal year-end; tax payment due 3 months after year-end.
Quarterly pre-payments of estimated corporate or personal income tax. Required when your annual tax owing exceeds $3,000 federally.
Money borrowed from or lent to your own corporation. If you borrow from your company, it must be repaid within a year or it becomes taxable income. Complex — always discuss with CPA.
7. Bookkeeping Process Terms
These are the terms that describe how bookkeeping is performed — the processes your bookkeeper carries out and the documents they produce.
The organized master list of all accounts used in your bookkeeping system. Assets, liabilities, equity, revenue, and expense accounts are all listed here with unique account numbers.
Comparing two records to confirm they agree. Bank reconciliation compares your books to your bank statement at month-end. Every difference must be investigated.
The master record of all financial transactions in your business, organized by account. The foundation from which all financial statements are produced.
A formal record of a financial transaction in the accounting system, showing which accounts are debited and credited. Used for corrections and adjustments.
A report listing all accounts and their balances at a specific date, confirming total debits equal total credits. Used by CPAs as the starting point for financial statement preparation.
The year-end process of finalizing all transactions, making adjusting entries, and locking the prior fiscal year so no further changes can be made to it in your accounting software.
8. Key Financial Ratio Terms
Financial ratios turn raw numbers into context. Understanding these terms helps you benchmark your business and spot problems early.
