Updated Checked by the Tax-Services.ca editorial team How we check
Which accounting software integration is worth setting up in Canada? The one that saves you work without breaking your records. We couldn’t find an official source that measures adoption trends, so this page skips the statistics and looks at what to connect, what to check, and what the CRA still expects of you.
What do people actually connect?
Four links come up again and again. The bank feed brings in transactions so you aren’t typing them. The sales channel, such as an online shop or a point of sale, pushes in revenue and the tax collected. Payroll sends wages and deductions to the ledger. And the tax side pulls out what you owe on GST/HST.
Each one removes a typing job. Each one also adds a place where a wrong setting repeats itself a few hundred times before anyone notices. That second part is what nobody mentions in the demo.
Where does the tax go wrong first?
Sales tax. An integration usually copies a tax code from one system to the other, and if the codes don’t match you get quiet errors. Say an Ontario shop sells $1,000 of goods before tax. At the 13% HST rate in our GST/HST calculator that’s $130. If the store platform is set to a province with only the 5% GST, such as Alberta, it records $50. Across a month of sales that gap grows, and it’s your liability, not the software’s.
| Same $1,000 sale | Rate | Tax recorded |
|---|---|---|
| Ontario, HST | 13% | $130 |
| Alberta, GST only | 5% | $50 |
| Difference | $80 |
Before you turn a connection on, run three test sales through it, one in each province you ship to. Compare the tax each shows with the calculator. That takes ten minutes.
Picture a small online candle shop run out of a garage in Kelowna. Orders ship from BC to Ontario, Alberta and Quebec, and the store platform was set up once, years ago, with one tax setting. A single test order per destination would show the problem in an afternoon. Without it, the books can be off on every out-of-province order for a year.
What about payroll?
Payroll integrations post wages and the employer’s share of deductions into the books. They don’t remit anything by themselves unless you’ve set that up, and remitting late has its own costs. Use the payroll remittance calculator to see what a pay run should add up to, then check that the ledger entry matches. If a bonus or a vacation payout gets coded as plain wages, the payroll deductions calculator will show a different figure than the one in the books, which is your cue to look.
Does changing software put my records at risk?
It can. The CRA says electronic records must stay in a readable electronic format, and usable on its equipment, for six years from the end of the last tax year they relate to. That doesn’t stop when you switch vendors or cancel a plan. Before you leave a system, export the full history, including attachments, in a standard file, and open it to make sure it reads. Then keep it.
Integrations add a wrinkle. If two systems each hold half the story, say invoices in one and payments in the other, you need both exports to rebuild it. Note down what lives where.
The CRA also says records kept on servers outside Canada aren’t treated as Canadian records without its permission, which it explains in its electronic record keeping circular. Ask every vendor in the chain where data is stored, including the ones behind the main one.
Mistakes that show up again and again
Turning on automatic categorisation and never reading it. Letting two tools both create the same invoice. Leaving an old connection live after you’ve moved on, so the same bank line lands twice. Giving a bookkeeper full access to everything when they only need the ledger.
One more. People assume the software files the return. It prepares figures, and you or your accountant still decide what goes on the form. If you’re self-employed, the self-employed tax calculator gives a rough cross-check on the profit number your software reports.
How do you know an integration is working?
Look for boring signs. The bank balance in the software matches the bank’s own statement to the cent. Sales tax collected in the books lines up with the tax on the invoices. Nothing sits in an “unmatched” or “suspense” bucket for weeks. And when you open a single transaction, you can follow it back to a source document. If one of those fails twice in a row, stop adding connections and fix that one first.
How to choose without chasing features
Ask which of your real problems the connection solves. If you type fifty bank lines a month, a bank feed pays off. If you have ten sales a month, it may not. Start with one integration, watch it for a full month, and only then add another. We don’t rank products and couldn’t verify any vendor claims, so the choice has to be tested on your own data.
Sources, and how we checked them
The six-year rule, the readable-format requirement and the point about foreign servers come from the Canada Revenue Agency‘s record-keeping pages, as published in 2026. The sample sale uses the HST and GST rates in our calculator. Nothing here comes from a vendor.
Frequently asked questions
Which integration should I set up first?
Usually the bank feed, because it saves the most typing. Add sales or payroll links one at a time and check each for a month.
Why does the sales tax differ between my store and my books?
Often the tax codes or province settings don't match. Run a test sale per province and compare with a GST/HST calculator.
Do I still need records if I switch software?
Yes. The CRA expects readable electronic records for six years from the end of the last tax year they relate to, so export your full history first.
Does integrated software file my taxes?
No. It prepares figures. You or your accountant choose what goes on the return.
Are there official numbers on adoption trends?
We couldn't find an official source, so this page makes no claim about trends.
