How to Read a Profit and Loss Statement

Your accountant emailed a PDF called "P&L," your bank asked for one, or you're staring at three columns the night before tax season trying to decide which line matters. You already know revenue sits at the top. What you need is a Canadian service-business read: CRA language, tax out of sales, delivery labour named as a cost, and your margin compared to peers in your industry, not to a blog's invented "healthy" percentage.

How do you read a P&L from top to bottom?

Start at the top and move down. Revenue, then the direct cost of delivering what you sold, then gross profit, then overhead, then non-operating items, then tax, then the bottom line. BDC describes the same waterfall: revenues and expenses over a period, ending in net income or loss.

Read the dollar amount on each line and that line as a percentage of revenue. Then compare this period to the same period last year. A busy month can look like a breakthrough until year-over-year margin moves the other way.

This post is for founders of Canadian service businesses who need to use the statement they already have. For a blank template or software walkthrough, start with a vendor guide such as Xero's. For public-company investing, use Investopedia. If the books are a mess and you have a filing deadline, book a bookkeeper first.

What is a profit and loss statement?

A profit and loss statement (also called an income statement, or P&L) shows revenues, expenses, and profitability over a period: a month, a quarter, or a year. BDC calls it a period report, usually with the current period next to the prior one. The SEC frames the math as Revenue − Expenses = Net Income (or Loss).

It doesn't show what you own or owe on a single day (that is the balance sheet), and it doesn't automatically equal the cash in your chequing account.

In Canada, filings often say "income statement" while software and bankers say "P&L." Same report. For sole proprietors and many partnerships, the structure maps to CRA Form T2125: gross income, cost of goods / gross profit, expenses, then net income or loss.

What are the three main parts of a P&L?

Most P&Ls break into three working blocks: money in from the work, the direct cost of delivering that work, and everything else it cost to run the business. BDC, SCORE, and the SEC all teach that shape.

Revenue / sales. What clients paid or accrued for your core services in the period. Asset sales and investment gains usually sit lower.

Cost of sales / cost of services, then gross profit. Direct costs of delivering what was sold. For service businesses, BDC uses "cost of services": contractor delivery labour, materials on client work, and similar direct costs. Gross profit is revenue minus those costs.

Operating expenses through to net income. Rent, utilities, marketing, insurance, office software, legal and accounting. Subtract those from gross profit for operating income. Interest, one-time items, and taxes come after. Net income is the bottom line after income taxes.

U.S. software guides sometimes say service businesses "typically don't" have cost of goods sold. If someone has to show up and do the work, that labour and related direct spend belongs above gross profit so the margin on the service is visible.

How do GST/HST and CRA language change how you read sales?

On Form T2125, Part 3A often starts with gross sales that include GST/HST collected, then subtracts GST/HST, other sales taxes, returns, and similar items. The tax you collected isn't keepable revenue. If your software P&L still shows tax-inclusive sales as "income," your top line is inflated and every margin underneath it is wrong.

Match the period to how you file. CRA generally has sole proprietors and many partnerships report on a calendar year; corporations choose a fiscal period of up to 53 weeks. GST/HST usually follows the same income-tax year.

CRA generally expects accrual reporting for business income. Cash accounting is limited (farmers, fishers, and self-employed commission agents in CRA's published guidance). If your bank feed looks "cash" and your accountant's P&L looks "accrual," know which basis you're holding before you make a pricing call.

What is gross profit vs net profit?

Gross profit is what is left after the direct cost of delivering the work. Net profit (net income) is what is left after operating expenses, non-operating items, and income taxes (BDC; SCORE).

Gross margin = gross profit ÷ revenue. Net profit margin = net income ÷ revenue. BDC walks $1 million in sales and $100,000 in net income as a 10% net margin to show the formula. Watch gross margin when pricing or delivery costs change; watch net margin when overhead, interest, or tax moved.

How to know if my business is profitable

Look at net income on the P&L for the period. Positive means revenue covered every cost on that statement; negative means a loss. Then check net margin and the same period last year so a one-off expense or a busy month doesn't fool you.

Profit on the statement is still incomplete without cash. Accrual revenue can sit unpaid; loan principal, equipment bought with cash, and owner draws move cash without always matching the expense line you expect. Founder threads on Reddit return to this constantly: the P&L can look fine while the account is empty. BDC notes that bankers often review net margin across several years as one metric among several.

Profit margin for a service business

Net profit margin is net income divided by revenue. There is no single "good" service number across industries. A consultancy, a salon, and a trades crew have different cost structures, and vendor blogs that quote one healthy band for all services aren't verified national averages.

In Canada, compare your margin to peers in the same industry and revenue band with ISED Financial Performance Data (the tool covers 1,000+ industries and bands including $30k-$5M and $5M-$20M, with 2024 data available). BDC warns that some tools report profit margin on income before taxes. Match definitions, or you'll beat a number you never measured. If a page quotes a fixed "healthy" percentage with no NAICS code and no data year, treat it as marketing copy and move on.

Bookkeeping basics

CRA requires records that support every income and expense claim: typically a day-to-day income and expense trail plus invoices, receipts, bank statements, and contracts, kept generally for six years. CRA doesn't prescribe a software brand; records must be reliable, complete, and supported, in English or French.

Keep business and personal spending in separate accounts, and stick to the same expense categories month to month. A monthly review means tax season isn't the first time you see the story. Mixed personal charges and shifting categories produce a report you can open and still can't trust.

Can a business be profitable and still run out of cash?

Yes. Profit is an accounting result for a period; cash is what clears the bank. Unpaid invoices, GST remittances, payroll timing, equipment bought with cash, debt principal, and owner draws all create that gap. When cash feels tight and the P&L looks fine, open receivables, the tax calendar, and the loan schedule before you cut prices.

What's the difference between a P&L and a balance sheet?

The P&L covers a stretch of time. The balance sheet is a snapshot on one date: assets, liabilities, and equity. Your accountant asking for both, not just a bank CSV, wants the movie and the still frame. Threads like this show up because bank exports alone don't produce either report cleanly.

What's the difference between a P&L and a cash flow statement?

The P&L explains profit. The cash flow statement explains how cash moved (operations, investing, financing). Use the monthly P&L for margin and cost structure, and a cash view for whether you can pay people and CRA on time.

How often should I look at my profit and loss statement?

Monthly for most small service firms: close the books, read margins, catch category drift while you still remember the month. Quarterly is the minimum for trend decisions. Year-end-only reading turns the P&L into a post-mortem.

Buyers later expect multi-year statements plus a current interim P&L and balance sheet. That habit also feeds how much your business is worth when someone asks for a real number.

FAQ

What does P&L stand for?
Profit and loss. Same report as an income statement in most small-business contexts (BDC; Xero).

Should my P&L use cash or accrual accounting?
CRA generally expects accrual for business income, with limited cash-method exceptions. A management report can still show cash for planning; know which basis you are reading.

Which numbers on the P&L should a founder actually watch?
Revenue (tax-exclusive), gross margin, operating expenses as a share of revenue, and net margin, each compared to last year and to ISED peers. Then check cash separately.

Where does owner pay show up?
Salary or wages usually sit in expenses. Draws and dividends often sit outside operating expenses and can make net income look stronger than the cash you took. Ask your bookkeeper to show the owner-pay path on your chart of accounts.

Do I need software?
No specific brand is required by CRA. You need complete, supported records. Software helps consistency; it doesn't invent discipline.

Print last month's P&L tonight. Strip tax out of sales if it is still in there, name the direct cost of each service line, write gross and net margins as percentages, and look up your NAICS band on ISED before you decide the month was "fine." That's how the statement starts earning its keep.
