I'll start with a confession. I think Square is a great product. The hardware is beautiful, the app works, the dashboard is clean, and a brand-new business owner can be taking payments 45 minutes after walking into a Best Buy with $79 for a reader. That's a real achievement.
The problem isn't Square. The problem is that the pricing model that made Square great at $500/month of card volume is the same pricing model that quietly costs you thousands a year once you're doing $30K+/month. Nobody at Square is going to call to suggest you've outgrown them. So owners stay. And pay.
This post is the math nobody walks you through.
What Square actually charges in Canada (2026)
Let's get the published rates on the table. As of 2026, Square Canada's standard pricing is:
| Transaction type | Fee |
|---|---|
| Tap, dip, or swipe in person | 2.65% per transaction |
| Manually keyed-in (in person) | 3.5% + $0.15 per transaction |
| Square Online / e-commerce | 2.9% + $0.30 per transaction |
| Invoices (sent and paid online) | 2.9% + $0.30 per transaction |
| Card on file / saved card | 3.4% + $0.15 per transaction |
| Square Reader (Bluetooth) | $79 (one-time) |
| Square Terminal (handheld) | $349 (one-time) |
| Square Stand (iPad POS) | $199 (one-time) |
Compared to legacy bank-owned processors loading you up with non-qualified surcharges, PCI non-compliance fees, batch fees, and annual fees — Square's pricing is genuinely cleaner. There's no statement fee. No monthly minimum. No early termination. The hardware costs more than "free" but you actually own it.
That cleanliness is also where Square's pricing logic stops being friendly to anyone past a certain size.
The math problem nobody explains
Square's 2.65% in-person rate covers everything — interchange, network fees, Square's margin, the dashboard, the support, the app. One rate, no breakdown.
The actual cost to Square on each transaction varies wildly by card type. Here's what Square is paying in wholesale interchange + network fees on a typical Canadian card mix:
| Card type | Wholesale cost to Square | You pay Square | Square's margin |
|---|---|---|---|
| Interac debit (chip + PIN) | ~$0.04 flat | 2.65% | Huge |
| Visa Debit / Debit MC | ~0.5% | 2.65% | ~2.15% |
| Standard consumer credit | ~1.4% | 2.65% | ~1.25% |
| Rewards credit | ~1.7% | 2.65% | ~0.95% |
| Premium / Infinite credit | ~2.0% | 2.65% | ~0.65% |
| Corporate / Purchasing | ~2.2% | 2.65% | ~0.45% |
The same till. The same swipe. Square's margin ranges from "razor-thin" on corporate cards to "five times the actual cost" on debit. Across a typical Canadian small business card mix — which skews heavily toward Interac debit and basic consumer credit — Square's average margin lands around 0.9% to 1.2% above their actual cost.
That's the spread. On $30K/month in volume, that spread = $270 to $360/month. On $75K/month, $675 to $900/month. Year over year.
For a deeper breakdown of why card type matters so much, the interchange explainer walks through the wholesale costs in detail.
Square at three real volume tiers
Let's run the numbers. Here's what Square actually costs versus other models at the three volume tiers I see most often.
Brand-new shops, side hustles, weekend markets
If you're just getting going — a new boutique in month two, a Saturday-market food vendor, a freelancer billing the occasional invoice — Square is genuinely the right call. The free dashboard, no monthly fees, no contract, and instant setup are worth more than the spread. There's nothing to optimize yet.
Verdict: The $23/mo gap is real, but small enough that the convenience and free hardware tradeoff is fair. Stay with Square. Revisit once you're consistently north of $10K/month — that's the inflection point.
Established cafés, salons, boutiques, small retail
This is where the math starts breaking in Square's favour. You're past the "I just need to take cards" phase. Your card mix is mature. You're a real business with real volume. And you're paying the same 2.65% on every transaction whether it's a basic debit or a corporate Visa.
Verdict: $225/month is $2,700 a year. That's a website, a year of social content, and a custom AI tool through the Boost program — all of which Square doesn't offer. At this volume the convenience tradeoff stops making sense.
Restaurants, busy salons, established auto shops, growing trades
If you're doing this kind of volume on Square, you're a profit centre for them. Their margin on your business is bigger than their margin on the entire bottom 60% of their merchant base combined. And they have zero incentive to call you and suggest a custom plan — because the standard plan is already the most profitable plan they offer.
Verdict: $700-$1,950/month, depending on which Dough model fits. Annualized, that's $8,400-$23,400. Plus Boost Premium tier (free 7-page website, monthly social content, custom AI). Staying on Square at this volume is leaving real money on the table every single month.
The four hidden costs Square doesn't put on a rate card
The 2.65% is the headline. There are four costs underneath it that nobody mentions during onboarding.
1. Hardware you have to rebuy
Square hardware is great. It's also locked to Square. The $349 Square Terminal is functionally useless the day you switch processors — you can't reflash it to run on any other network. The $199 Square Stand is the same story. Even the $79 Reader is hardware you've paid for and can't repurpose.
This isn't a knock — Apple's iPhones don't work on other networks either. But over a few years of upgrading and replacing devices, that's real money that's gone the day you outgrow Square. A Clover Flex bought outright through Dough is yours forever and works for any Clover-network processor (which is most of them in Canada).
2. Account holds and freezes
Square — like Stripe, PayPal, and most flat-rate processors with no human underwriting — uses automated risk algorithms to flag accounts. If your transaction volume jumps quickly, or you suddenly have a few high-ticket transactions, or you receive a chargeback the system doesn't like, the algorithm can put a hold on your funds.
This is rare for small, stable businesses. But it happens enough that there's a whole reddit's worth of "Square froze my account for 90 days" threads. Real, traditionally-underwritten merchant accounts (the kind Dough sets you up with) have a human in the loop and don't trigger these holds.
3. Customer service
Square has email support and chat, with a phone line that's notoriously hard to reach. For a brand new business, this is fine. For an established business where a payment problem at 9am Tuesday means losing money for every hour the terminal is down, "we'll get back to you within 24 hours" is not the right SLA.
I get phone calls and text messages from Dough merchants directly. Same day. That's not a competitive feature, that's just how a real processor with humans involved works.
4. Zero perks
This is the one nobody talks about. You pay Square ~$10,000 a year in fees on a $30K/month shop. In return, Square gives you... the ability to take payments. That's it. No marketing help, no website, no social content, no AI tool, no Google review cards.
The Boost program is Dough's entire pitch on this. The fees you'd pay anyway get reinvested as free business growth tools. The same $30K/month merchant on Dough's Boost Pro tier gets a free 5-page website, 8 social posts a month, and a custom GPT — all on top of paying less in processing.
When Square is genuinely the right choice
I'm not anti-Square. Some businesses should absolutely stay on Square:
- Brand-new businesses under $5K/month. The convenience-vs-cost math is in Square's favour. Get to revenue first, optimize processing later.
- Highly seasonal businesses with unpredictable downtime. Pop-up markets, farmers' markets, food trucks in single-season climates, summer-only attractions. Square's no-monthly-minimum structure works for businesses that go to zero for months at a time.
- Businesses where you'll never break $10K/month. If you've been at $4K/month for three years and that's by design, Square's overhead is the right shape for you.
- Pure online businesses doing under $10K/month. Square Online's e-commerce integration is solid for that size. Past $10K online, Stripe or a dedicated gateway is more capable.
If you're outside those four buckets, Square is almost certainly costing you more than it should — and giving you less in return than it could.
The switch is easier than you think
The biggest reason owners stay on Square at $30K-$75K/month isn't loyalty. It's friction-aversion. They assume switching means a week of downtime, a new bank account, and customers asking why the till is acting up.
None of that is true. The whole switch is 2 to 3 days, your bank account stays exactly where it is, and customers see no difference. The new terminal arrives pre-programmed. You run a test transaction, confirm it settles, and decommission the Square device. Full walkthrough here →
The only Square-specific thing to watch: if you have customer cards saved in Square's Card on File system, those tokens don't transfer (Square locks them in). For recurring billing setups, the new gateway will need to re-tokenize those customers — but they'll only see one extra "confirm your card" email, not a full re-enrollment.
The honest comparison
Here's how Square stacks up against Dough at a glance:
| Square | Dough | |
|---|---|---|
| In-person rate | 2.65% flat | IC+ ~1.9-2.1%, or surcharging $0 on credit |
| Monthly fee | $0 | $0 |
| Hardware cost | $79-$349 (locked) | Purchase or qualify for free through Boost |
| Setup time | ~1 hour | 2-3 days |
| Underwriting | Algorithmic | Human |
| Account freezes | Possible | Rare (real merchant account) |
| Support | Email + chat + hard-to-reach phone | Direct phone + text to a real person |
| Surcharging support | No | Yes — fully managed |
| Dual pricing support | No | Yes |
| Business growth perks | None | Boost: free website, social, AI tool |
| Contract | None | Month-to-month or 4-year (your choice) |
| Best for | New businesses under $10K/mo | Established businesses $10K+/mo |

The TL;DR on Square's real cost
If you're under $10K/month and your business is genuinely small or seasonal, Square is the right call and you should ignore most of this post. The convenience is worth the spread.
If you're between $10K and $30K, you're at the inflection point. The savings are real but not life-changing. The Boost perks (free website, social, AI) might be more compelling than the processing savings themselves.
If you're past $30K/month, every month you stay on Square is a month you're handing them money that should be staying in your business. The math doesn't lie. Run your effective rate (total fees ÷ total card volume), and if it's over 2.5%, you're paying for someone else's profit margin.
The TL;DR
- Square charges 2.65% on every in-person transaction regardless of card type. The wholesale cost to Square ranges from ~$0.04 on debit to ~2.2% on premium credit — meaning their margin is biggest on the cheapest cards to process.
- Under $10K/month: Square is the right choice. Stay put.
- $20K-$30K/month: You'll save roughly $225/mo (~$2,700/yr) switching to Dough IC+. Plus Boost perks Square doesn't offer.
- $75K+/month: You'll save $700-$1,950/mo. Annualized that's $8,400-$23,400. Plus a free website, social content, and a custom AI tool through Boost Premium.
- Hidden costs Square doesn't mention: hardware is locked to their network, account holds happen with algorithmic underwriting, support is email-first, and there are zero business growth perks for the fees you pay.
- The switch is 2-3 days. Your bank account doesn't change. Customers see no difference. Full walkthrough here.
