Updated Checked by the Tax-Services.ca editorial team How we check
Business intelligence for a small Canadian company mostly means reading your own books properly. You don’t need a data team. You need clean records, a handful of ratios you check every month, and the habit of asking what changed. There’s no official guidance on business intelligence itself, so this page sticks to what the CRA says about records and to numbers you can work out with the calculators here.
What financial data do you already have?
More than you think. Your accounting software holds sales by month, costs by type, payroll and what customers owe you. The CRA counts accounting systems, point of sale systems and other computerized records as business records, and says you keep them as carefully as paper. It also says the responsibility stays with you even when a bookkeeper or an app holds them. Its page on keeping records is a good place to start.
So the first job is dull. Make sure every sale and every cost lands in the right category, every month. Analysis on top of messy categories gives you confident nonsense.
Which numbers are worth watching?
Fewer than you’d expect. Pick a short set, look at them monthly and write down what moved.
| Measure | What it tells you | Tool |
|---|---|---|
| Gross margin | What’s left of each sale after direct cost | Profit margin calculator |
| Return on a spend | Whether a purchase paid for itself | ROI calculator |
| Payroll cost per period | What staff cost once employer shares are added | Payroll remittance calculator |
| Tax as a share of profit | What you should set aside | Corporate tax calculator |
Margin comes first. Take a product that costs $60 and sells at $100. The profit margin calculator gives a 40% margin and a 66.7% markup. Both are right, and they answer different questions. Margin is a share of the price, and markup is a share of the cost. If you quote the wrong one to a supplier or a lender you’ll be off by a lot.
What does a monthly check look like?
About an hour, once the books are up to date. Same order every month, so you can compare like with like.
- Compare this month’s sales with the same month last year, not just with last month.
- Look at the three biggest cost lines and ask which one moved most.
- Work out gross margin for each product or service you sell.
- Check what customers owe you and how long it has been.
- Write two sentences about what changed and what you’ll do about it.
The last step matters most. A number you looked at and wrote nothing about is just a number.
How do you tell if a spend paid off?
Say you put $12,000 into a reporting tool and better tracking, and three years on you can put a $15,000 value on the gain. The ROI calculator shows a 25% total return, or about 7.7% a year. That’s a modest result. It ignores tax and fees, and the $15,000 is your own estimate, so it’s only as good as your judgement.
The same approach works on anything you can price. Ask what you paid, what came back, and over how long. If you can’t answer the middle part, you’ve found a gap in your data, which is a useful thing to learn.
What does your payroll really cost?
Owners often watch wages and forget the extras. An Ontario employee paid $3,000 every two weeks costs about $3,228 per period once your CPP and EI shares are in, according to the payroll remittance calculator. You’d send the CRA about $961 each period for that person. Track the full cost against the sales that person helps bring in.
What goes wrong with business data?
Mostly the inputs. Personal spending mixed into the business account. Costs posted in the wrong month. Two people naming the same customer three ways. Tools and dashboards make these problems look official instead of fixing them.
Another trap is the average. A 40% margin overall can hide a product line that loses money. Picture a shop that sells one item at $100 that cost $60, and one at $50 that cost $48. Together that’s $150 of sales and $42 of profit, a healthy-looking 28%. The second item alone earns $2 on $50, which is 4%, barely a few bucks of profit. Split the numbers by product or client before you decide anything.
Estimate tax as you go, too. The corporate tax calculator gives a combined Ontario small business rate of 11.696% for 2026, but that figure is a blend, since Ontario changed its rate in July 2026. Use it to plan a reserve, not to file.
Do you need special software?
Probably not. Most small firms get what they need from their accounting package and a spreadsheet. Buy a fancier tool only after you’ve caught yourself wanting a number you can’t get, and ask whether a better category in your books would solve it for free.
Where the numbers come from
The record rules come from the CRA‘s guide on keeping records, which asks for six years from the end of the last tax year. The margin, ROI, payroll and tax figures come from the calculators on this site, using 2026 federal and Ontario data. No analytics software was reviewed, so nothing here says what any product can do.
Frequently asked questions
Do I need special software?
Not to start. Your accounting software already holds sales, costs and payroll. Clean categories matter more than a new tool.
What is the difference between margin and markup?
Margin is profit as a share of the price, and markup is profit as a share of the cost. A $60 item sold at $100 has a 40% margin and a 66.7% markup.
How long do I keep financial records?
The CRA says six years from the end of the last tax year they relate to, and that includes computerized records.
Is a bookkeeper responsible for my records?
Not in the CRA's eyes. You stay responsible even when someone else keeps them.
How do I know if a spend paid off?
Compare what you paid with what came back and over how long. The ROI calculator gives the total and yearly return.
