POS system in Canada: how to choose the right one

A POS system in Canada is the software and hardware you use to ring up sales, calculate sales tax, take payments, and track what you sell. Choosing one here is different from choosing one in the US for three reasons: sales tax changes by province and sometimes by product, your customers expect to pay with Interac debit, and if you sell in Quebec, receipts and software have to work in French. Get those three right and the rest is the usual comparison of features and price.

We'll take them one at a time, with rates current as of October 2026, then cover the costs to compare and the questions to ask before you sign a contract.

What does a POS system do for a Canadian business?

A point of sale system does the same core job everywhere: it holds your product or menu list, rings up sales, adds tax, takes payment, prints or sends a receipt, and reports on what sold. The Canadian parts sit underneath. You need tax codes for every province you sell in, a payment terminal that takes Interac, and French support if you need it.

Most setups have four pieces:

• POS software, usually a monthly subscription, running on a tablet, a computer, or a dedicated register.
• Hardware such as a receipt printer, a cash drawer, and a barcode scanner.
• A payment terminal, which most Canadians call a debit machine. Our guide to choosing a debit machine covers the options.
• Payment processing, the merchant account that moves the money. For most businesses, this is the biggest ongoing cost.

How do you set up GST, HST, PST, and QST in a POS?

Set up tax by province first, then by product. The rate you charge depends on where the sale is made, which the Canada Revenue Agency calls the place of supply. Here are the general rates as of October 2026, from CRA's rate table and the provincial finance ministries:

Two rows deserve a second look in any POS demo. Nova Scotia's HST dropped from 15% to 14% on April 1, 2025, according to CRA, so an old tax table is wrong. Manitoba calls its provincial tax the retail sales tax, or RST, so label it that way in your POS.

The math matters as much as the rate. In Quebec, Revenu Québec says the QST is calculated at 9.975% "on the selling price excluding the GST," so the two taxes aren't stacked. Where a provincial sales tax applies, CRA says to calculate the GST on the price without the PST. Here's what a $40 taxable item should come to at the till:

Which products need special tax codes?

The table above shows general rates. Your POS also needs tax codes at the product level, because not everything is taxed the same way. British Columbia, for example, says its 7% PST applies to goods and services generally, "with some exceptions." Check your province's rules for what you sell before you load your catalogue.

Ontario is the clearest example of why this matters at the till. Ontario gives a point-of-sale rebate of the 8% provincial portion of the HST on specific items, including books, children's clothing and footwear, children's car seats and booster seats, diapers, newspapers, and qualifying food and beverages. On those items, you charge only the 5% federal part.

The food rule is the easiest one to get wrong. The rebate applies to qualifying prepared food and drinks only when the total price of all qualifying items in the purchase, before HST, is no more than $4. So in a Toronto café:

• One $3.50 coffee: 5% tax, about 18 cents, for a total of $3.68.
• Two $3.50 coffees on the same bill: $7.00 is over the limit, so the full 13% HST applies, 91 cents, for a total of $7.91.

A POS that applies the rebate item by item, instead of checking the whole order, will charge the wrong tax all day long.

What should a Canadian receipt show?

CRA's rules are short. On your receipts and invoices, you have to show the GST/HST rate that applies, and where HST applies, the total HST rate. Don't split HST into its federal and provincial parts. You can either list the tax as its own line or state clearly that the total includes it.

Most POS systems handle this once the tax codes are right. Still, print a test receipt for each tax code before you open, and look hardest at provinces with two taxes. Your receipt should make it obvious which tax applied to which item, especially when a single order mixes rebated and fully taxed products.

Do you need bilingual receipts? Quebec's French-language rules

If you sell in Quebec, yes, at least in French. Section 57 of the Charter of the French language says invoices, receipts, and similar documents must be drawn up in French. Section 89 allows French and another language to be used together where the Charter doesn't require French only, so English can appear alongside the French. The Quebec government's summary of business obligations lists contracts, invoices, and receipts meant for consumers among the documents to draft in French.

Software is covered too. Section 52.1 of the Charter says computer software must be available in French unless no French version exists. When you compare POS systems for a Quebec location, ask whether the French version is complete: menus, staff screens, receipts, and customer-facing prompts on the terminal.

Outside Quebec, section 57 doesn't apply. But if you have stores in more than one province, or you sell to customers in Quebec, picking a POS that prints clean French and English receipts saves you from running two setups later.

How does a POS system take Interac and card payments?

The POS rings up the sale; a payment terminal and a processor take the money. To accept Interac Debit, Interac says you have to connect with an acquirer, so whatever POS you choose has to work with a terminal and a processor that support Interac.

Your customers will use it. Payments Canada counts debit cards at a quarter of all payment transactions in 2025, second only to credit cards at 43%. Interac tap payments have limits of up to $250 per transaction, set by the customer's bank, so the terminal has to take chip and PIN for larger sales too.

Two setup choices matter more than they look:

1. Integrated or standalone terminal. An integrated terminal receives the sale amount from the POS, so staff don't key it in twice. Every amount keyed by hand is a chance to overcharge a customer or end the day with totals that don't match.
2. Bundled or separate processing. Some POS providers require you to use their own payment processing. That can be fine, but it means you can't shop the biggest ongoing cost separately. Ask before you sign, and see how we compare with Square and Helcim if you're weighing those options.

What does a POS system cost in Canada?

The price on the website is rarely the whole cost. Compare these pieces over at least three years:

For card processing, the Code of Conduct for the Payment Card Industry in Canada helps you compare. Your processing agreement has to include a Cost per Transaction Disclosure and a Disclosure of Fees, and your monthly statement has to show your effective merchant discount rate for each card type. Ask for both disclosures before you sign, not after. Our guide to credit card fees in Canada explains what's in those numbers.

How to test your POS tax setup before you open

Don't wait for your first customer, or your first GST/HST return, to find a tax error. Before opening day, or before you switch systems, run test sales for every tax situation you expect to see:

1. Ring up one item from each tax code and check the tax against a calculator.
2. In Ontario, ring up a single coffee under $4 and then two coffees on one bill, and confirm the HST changes.
3. In Quebec, confirm the QST is worked out on the price before GST, and that the receipt prints in French.
4. Mix a taxable item and a rebated or exempt item on one bill, and read the receipt the way a customer would.
5. Refund a test sale and make sure the tax comes back off too.
6. Run the end-of-day report and check that the tax totals match the test receipts.

If anything is off, fix it in the tax codes, not by overriding prices at the till. An override lets one error repeat across hundreds of sales before anyone notices.

Questions to ask before you sign a POS contract

1. Can you set up tax codes for every province I sell in, including online orders shipped to other provinces?
2. How does the system handle Ontario's point-of-sale rebate and its $4 limit on prepared food?
3. Does it calculate QST on the price before GST?
4. Can it print receipts in French, or in French and English?
5. Is the French version of the software complete, including staff screens?
6. Does it work with a terminal that takes Interac chip and PIN and tap?
7. Am I required to use your payment processing?
8. What is the cost per transaction for Interac, Visa, and Mastercard, in writing?
9. How long is the contract, how does it renew, and what does it cost to leave?
10. Who owns the hardware, and what happens to it if I cancel?
11. Can I export my sales, product, and customer data if I switch?
12. When will card payments land in my bank account?

Mistakes to avoid

• Using one tax setting for every location, or for online orders delivered to other provinces.
• Printing HST split into federal and provincial amounts.
• Applying Ontario's food rebate item by item instead of to the whole order.
• Opening a Quebec location with English-only receipts.
• Signing for bundled processing without seeing the per-transaction cost.
