Most “cheapest POS system Canada” lists compare sticker prices: a $69 reader here, a free app there. That is the wrong number. What a POS system costs your business is the hardware plus what you pay on every card sale for as long as you use it, and the second part is almost always bigger.
Below we work it through the way we would at your counter, with real published rates and one normal month of sales.
What is the cheapest POS system for a small business in Canada?
The cheapest POS system is the one with the lowest total cost over a year: hardware, monthly software and processing fees added together. For most small businesses the processing fees are the biggest number, so the cheapest system is usually the one on the lowest-cost rate plan, not the one with the lowest sticker price.
A $69 card reader on a 2.5% flat rate can cost more over twelve months than a full counter system on a surcharge plan. So start with the rate, then pick the hardware that fits how your counter works.
How much does a POS system cost in Canada?
Hardware runs from about $69 for a basic reader to around $1,000 for a full countertop register, and many plans add no monthly software fee. Processing is the ongoing cost, and on a $25,000 month it can range from about $10 to over $500 depending on the plan.
For a sense of hardware prices, Square’s Canadian store lists the Square Reader at $69, Square Terminal at $399 and Square Register at $999. Square’s free plan is $0 a month, with paid software from $35 a month. Clover hardware is usually quoted by the provider that places it. With us, the terminal is included on our Variable and Surcharge plans, and none of our three plans carries a monthly fee (our published rates).
Why do processing fees matter more than the hardware price?
Because you pay for the hardware once, but you pay processing on every sale for years. On a $25,000 month, the gap between the most and least expensive rate plan is about $500 a month, roughly $6,000 a year, which is more than any terminal costs.
From our side of the counter, the whole thing comes down to two questions: are you getting a better rate, or are you getting better value for what you pay? Usually it is one or the other. Cheap hardware on an expensive rate is the most common mistake we see when a business owner shows us their statement.
Here is what that looks like in real life. An auto shop on Finch was paying about $2,000 a month in credit card fees. We moved it to our Surcharge plan, and its credit card fees went to $0: the 2.4% is now paid by the customers who choose to pay by credit, and the shop pays only the 5¢ per debit transaction. Same counter, same customers, about $2,000 a month back in the business.
What is the cheapest way to accept card payments?
For most small businesses the cheapest way is a surcharge program, where the cardholder pays the credit card fee and you pay only a small debit cost. If you would rather not surcharge, interchange-plus pricing is usually cheaper than a flat rate once you process real volume.
Here is one month at a typical small business: $25,000 in card sales, a $35 average sale, 70% paid by credit. The Variable estimate assumes interchange plus network assessment averages 1.40%, which changes with your card mix.
| Plan | Credit card | Debit | Monthly fee | Est. cost to you on $25,000 |
|---|---|---|---|---|
| Flat rate (Square direct, and our Fixed plan) | 2.50% | 0.75% + 7¢ | $0 | ≈ $508.75 |
| Interchange-plus (our Variable plan) | Interchange + 0.20% + assessment | 5¢ | $0 | ≈ $290.71 |
| Surcharge (our Surcharge plan) | $0 to you, 2.40% paid by cardholder | 5¢ | $0 | ≈ $10.71 |
The flat-rate row is the same on both: Square’s published Canadian rates are 2.5% on credit and 0.75% + 7¢ on debit, which matches our Fixed plan. On Fixed, the difference with us isn’t the rate. It’s that we install it, train your staff and pick up the phone 24/7. The real savings are in the other two rows. Run your own numbers in the cost calculator.
What is the difference between a debit machine and a POS system?
A debit machine, also called a card machine or POS terminal, only takes payments. A POS system also rings up sales, tracks inventory and reports on your day, and most modern POS systems have the card machine built in.
If you just need to take cards next to a cash register you already like, a standalone terminal is enough. If you are still writing tickets by hand or counting stock on paper, a full POS such as a Clover Mini or a Square Register replaces the debit machine and the register in one box. Our Clover vs Square guide covers which fits which counter.
Can I take card payments on my phone?
Yes. Tap to Pay on iPhone and Android turns a phone into a contactless card reader with no extra hardware, and a plug-in reader like the Square Reader costs $69.
It is the cheapest possible hardware setup and a good backup on day one. It is not a full counter system, though. There is no printer, no cash drawer and no kitchen tickets, so most shops with a fixed counter outgrow it quickly.
What does credit card processing cost in Canada?
Most of the cost is interchange, the fee the card networks and issuing banks set, and the Government of Canada’s own example works out to roughly 1.3% of credit sales. Your processor’s markup sits on top, and that markup is the part that differs from one provider to the next.
In its announcement, the Department of Finance says a store processing $300,000 in credit card payments pays nearly $4,000 a year in interchange. Everything above that is your processor. On interchange-plus you can see both parts on your statement. On a flat rate you can’t.
Did the 2024 interchange cut lower my fees?
Only if your processor passed it on. Interchange fell by up to 27% for eligible small businesses on October 19, 2024, but a flat-rate plan keeps charging the same percentage whatever interchange does.
You qualify with under $300,000 a year in Visa sales or under $175,000 in Mastercard sales. Under the revised industry code, processors have to tell eligible businesses if the reduction will not be passed on in full. On an interchange-plus plan the lower interchange flows through automatically. If you are on a flat rate and never got that notice, ask.
Can I legally charge customers a credit card fee in Canada?
Yes, outside Quebec. You can add a surcharge of up to 2.4% to credit card sales, as long as you disclose it before the customer pays and it does not exceed your cost of accepting the card.
The Financial Consumer Agency of Canada lists the 2.4% maximum surcharge cap and says customers must be able to pay another way, such as debit or cash, without penalty. Debit and prepaid cards can’t be surcharged. The full rules, signage included, are in our credit card surcharging guide.
So which is the cheapest POS system for you?
The honest answer depends on your card mix: how much is credit versus debit, your average sale, and your monthly volume. That mix moves the number far more than the headline rate does.
