Why So Many Canadian Merchants Are Rethinking Square
Square built its reputation on simplicity. Sign up in minutes, get a sleek card reader, and pay one flat rate on every transaction. For a lot of Canadian startups and side hustles, that simplicity was exactly what they needed in the beginning.
But as businesses grow, that same flat-rate simplicity starts to work against them. Owners who once loved Square's ease of use begin noticing that their processing costs climb every month, even when their sales patterns barely change. That's when they start asking a very specific question: why are businesses leaving Square for interchange plus pricing, and is it time for me to do the same?
This isn't a fringe trend. Across Toronto, Vancouver, Calgary, Montreal, and Ottawa, thousands of Canadian merchants have made the switch from flat-rate processors like Square to interchange-plus pricing models, often saving 20-40% on their monthly processing costs. In this article, we'll break down exactly why businesses leave Square for interchange plus arrangements, what interchange-plus actually means, and how to know if switching makes sense for your business.
Understanding Square's Flat-Rate Pricing Model
Square charges a single blended rate for card transactions, typically around 2.65% for in-person purchases and higher for online or keyed-in transactions. Every card, every customer, every transaction gets the same rate regardless of what it actually costs Square to process.
That flat rate feels predictable, which is part of Square's appeal. But predictability comes at a price: you're always paying a premium blended into that rate to cover the more expensive cards, even if most of your customers pay with cheaper ones.
Where the Hidden Cost Lives
Every card transaction in Canada involves an interchange fee set by Visa, Mastercard, or other networks. These fees vary significantly:
- Standard consumer debit and basic rewards cards carry lower interchange rates
- Premium rewards, travel, and corporate cards carry substantially higher interchange rates
- Card-not-present transactions (online, phone) typically cost more than in-person tap or chip transactions
With Square's flat rate, you never see this breakdown. You simply pay the same 2.65% no matter what mix of cards your customers use. If your customer base skews toward premium rewards cards, which is increasingly the case in Canada, you may actually be overpaying relative to the true cost of those transactions on lower-cost cards, while barely breaking even on the high-cost ones.
The Real Reasons Businesses Leave Square for Interchange Plus
1. Growing Transaction Volume Exposes the Markup
When a business processes $5,000 a month, a flat rate feels manageable. When that same business scales to $50,000 or $100,000 a month, the markup embedded in Square's flat rate becomes a real line item. This is the single biggest reason why businesses leave Square for interchange plus pricing: at higher volumes, the savings from paying true interchange rates plus a transparent markup can add up to thousands of dollars annually.
2. Lack of Transparency in Blended Rates
Interchange-plus pricing separates your costs into two clear parts: the actual interchange fee (set by the card networks, non-negotiable, and identical across all Canadian processors) and a fixed markup charged by your processor. This structure means you can see exactly what you're paying for and audit your statements. Square's blended model bundles everything together, making it nearly impossible to know if you're being overcharged.
3. No Room to Negotiate
Square doesn't negotiate rates. It's a one-size-fits-all platform built for scale, not for relationship-based pricing. Businesses that grow past a certain size often find that traditional and interchange-plus processors are willing to negotiate the markup portion of their fees, something that's simply not on the table with Square.
4. Higher Costs for Card-Not-Present and Premium Cards
Restaurants, e-commerce shops, and service businesses that take a lot of phone or online orders often get hit hardest by Square's card-not-present rates, which run higher than in-person rates. Businesses in these categories frequently see the largest savings when they move to interchange-plus pricing with a dedicated merchant account.
5. Limited Support and Generic Hardware
Square's customer support is designed for self-service at scale. Many growing Canadian businesses want a dedicated account manager who understands their industry, whether that's retail, restaurants, or healthcare, and can recommend the right hardware and pricing structure. Interchange-plus providers in Canada often pair transparent pricing with more personalized service.
How Much Can You Actually Save?
The savings from switching depend heavily on your transaction volume, average ticket size, and card mix. As a general rule:
- Low-volume businesses (under $10,000/month) may see modest savings and might still find Square's simplicity worthwhile
- Mid-volume businesses ($10,000-$50,000/month) often save 15-30% by switching to interchange-plus
- High-volume businesses (over $50,000/month) frequently save 25-40% or more, since the fixed markup on interchange-plus becomes a smaller percentage of overall cost as volume grows

Interchange Plus vs. Other Processors
Square isn't the only flat-rate option Canadian businesses are reconsidering. Many merchants comparing their options also look closely at Stripe, which uses a similar blended pricing approach for online businesses, or bank-bundled processing options through providers like TD or Desjardins, which can carry hidden fees of their own. If you're evaluating your options broadly, it's worth reviewing how these providers stack up. Our Compare processors page breaks down the differences, and we have dedicated comparisons for Stripe, TD, and Desjardins if you want a side-by-side look.
Point-of-sale hardware is another factor. Square's ecosystem is closed, meaning you're locked into their hardware and software. Businesses that want more flexibility often look at Clover or Lightspeed systems, which can be paired with interchange-plus processing for the best of both worlds: modern POS features without the flat-rate markup.
Is Switching Right for Your Business?
Not every business should leave Square. If you're a very low-volume operation, a seasonal pop-up, or you genuinely value the "one predictable rate" simplicity over maximizing savings, Square can still make sense.
But you should seriously evaluate a switch if:
- Your monthly processing volume exceeds $10,000-$15,000
- You've noticed your effective rate creeping up over time
- A large share of your sales involve premium or corporate cards
- You process a lot of card-not-present transactions (phone or online orders)
- You want a dedicated account manager instead of a call centre
- You're expanding and want processing that scales with volume discounts
What the Switching Process Looks Like
- Gather 2-3 months of recent Square statements
- Have a processor calculate your true interchange costs versus what you're currently paying
- Compare the proposed markup and any monthly or PCI compliance fees
- Confirm hardware compatibility or get new terminals that support interchange-plus billing
- Set a transition date and run parallel processing briefly if needed to confirm accuracy
This entire process typically takes one to two weeks and can be done with minimal disruption to your day-to-day operations.
Industry-Specific Considerations
Different types of Canadian businesses experience this shift differently:
- Restaurants and hospitality often see savings from lower card-not-present rates when integrating online ordering with in-person processing. See our Restaurant solutions and Hospitality solutions pages.
- E-commerce businesses frequently carry the highest card-not-present exposure and see some of the largest percentage savings. Learn more on our E-commerce solutions page.
- Salons, spas, and healthcare practices with recurring appointment-based billing benefit from predictable, transparent statements. Check out Salon & spa solutions and Healthcare solutions.
- Construction and automotive businesses with larger average transaction sizes often see outsized dollar savings even from small percentage-point improvements. Visit Construction solutions and Automotive solutions for more.
- Nonprofits processing donations can also benefit from lower effective rates, freeing up more funds for their mission. See Nonprofit solutions.
Businesses across the country, from Toronto and Vancouver to Calgary, Montreal, and Ottawa, are making this switch as they scale past the point where flat-rate pricing makes sense.
Making the Switch with Confidence
The trend is clear: as Canadian businesses grow, more of them are asking why businesses leave Square for interchange plus pricing, and the answer almost always comes down to transparency and cost at scale. Flat-rate pricing is a fine starting point, but it's not built for businesses that want to control costs as they mature.
