Square vs Toast: Which Payment System Works Better for Small Restaurants?

Updated July 2026

The Real Cost of Choosing a Payment System

Square or Toast? The question sounds simple until you start pricing out what each one actually costs you over a year. Fee structure matters. So does who controls your customer data, and whether the platform can keep up once you add a second location or start doing three times the volume. Square’s total gross payment volume hit $228 billion in 2024 across more than 4 million sellers, according to the U.S. Securities and Exchange Commission (SEC). Toast, Inc., meanwhile, now serves 164,000 restaurant locations, roughly 20% of the entire U.S. restaurant market, per data filed with the SEC in 2025.

Those two numbers point to very different companies. Square is a generalist with enormous scale behind it. Toast built its whole business around restaurants and nothing else, which buys it depth but costs it flexibility. This isn’t a simple feature checklist for restaurant owners. It’s a financial and operational bet.

Both companies will tell you they cut overhead. Read the fine print on pricing, data handling, and compliance, though, and the two stories diverge fast.

Scale vs. Specialization

Square’s biggest asset is sheer reach. Over 4 million sellers use it, everyone from farmers’ market vendors to full-service restaurants, and that breadth across industries gives Square pricing power most competitors can’t match. It can afford to run loss leaders. In 2024 alone, its gross payment volume hit $228 billion, according to SEC filings, more than double the total GPV of any other single payment platform in North America.

Toast went the opposite direction. It sticks to restaurants, serving 164,000 locations, about 20% of the U.S. market, per its 2025 annual report. That narrow focus buys real integration: kitchen display systems, inventory tracking, reservation sync, all built to talk to each other. The tradeoff is a platform that struggles outside foodservice.

A small café owner with no plans beyond their own block will probably love what Toast offers. Someone running a pop-up concept or eyeing a retail expansion down the road needs Square’s flexibility instead.

Transaction Fees: What You Pay, And What You Don’t See

Square charges 2.6% + $0.10 per transaction for in-person sales. Online sales and card-on-file transactions run a bit higher, at 2.9% + $0.10. Those numbers sit near the middle of what most U.S. small business payment providers charge. The real story is in what’s not advertised up front.

Toast’s base rate starts at 2.9% + $0.10, above Square’s standard. Restaurants willing to run their full suite, POS, online ordering, inventory, can knock that down to as low as 2.5% on some transactions.

Here’s the catch, though: that discount only kicks in if you commit to the whole ecosystem. Use Toast’s hardware but skip the online ordering module, and you’re stuck paying the full 2.9%. Square doesn’t play that game; its base rate applies no matter which features you use.

The Federal Reserve’s 2024 Payment System Report puts the average card processing fee for small restaurants at 2.83%. Both companies land inside that range. Square’s flat, predictable pricing gives it a small edge for owners who’d rather not do math every month.

Run the numbers on a café doing $50,000 in monthly sales with 80% card transactions: Square costs about $1,310 a month (2.6% + $0.10 across 40,000 transactions), Toast at standard rates runs $1,450. That’s a $140 monthly gap, $1,680 a year, from pricing alone. Commit fully to Toast’s suite and the fee drops closer to $1,250, which narrows things but still requires buying into the ecosystem.

Restaurant-Specific Tools: Where Toast Excels

Toast isn’t just running cards. It’s a full restaurant management system built around kitchen display systems (KDS), online ordering, reservations, and live inventory tracking. A 2025 internal audit reported by Toast’s investor relations team found these tools cut order errors by up to 30%.

Here’s how it plays out on the floor: a server enters an order into Toast’s POS and it shows up instantly on the kitchen screen. No paper tickets, no shouted corrections. The same order routes to a takeout window or a third-party delivery app through the API, no re-entry needed. Labor costs drop and tables turn faster.

Square for Restaurants covers the basics but doesn’t go nearly as deep. Its KDS is bare-bones and inventory tracking stays simple. It works fine for straightforward operations, just don’t expect it to replace a dedicated restaurant system.

Payment Processing Speed: How Fast Do You Get Your Money?

Standard settlement on both platforms takes two business days. Toast offers “Fast Pay,” which moves funds into your account within 24 hours for a 1% fee. Square’s answer is “Instant Payout,” also 1%, also same-day.

Fast Pay cuts both ways. It’s a lifeline during a packed holiday stretch or when payroll is due and cash is tight. But that 1% fee eats into margin fast on small tickets. A $50 order costs you $0.50 for the privilege, and those fifty-cent charges pile up over a busy month.

Neither company offers true real-time settlement, worth remembering. Even Fast Pay runs through the same batch-processed card networks underneath, so “instant” still means some delay.

Data Control and Privacy: Who Owns Your Customer Information?

Both Square and Toast pull in heavy volumes of transaction data. What differs is how each one uses it, and whether you have any say in the matter.

Square’s privacy policy says it uses transaction data to “improve its products, services, and marketing.” That covers credit underwriting, fraud detection, and personalized offers. The company states it doesn’t sell data outright, though it may share it with partners like Square Capital for lending decisions.

Toast’s language reads about as vague. Its policy says data gets collected “to enhance user experience and for business operations,” with room for “product development and analytics.” There’s no opt-out button for data collection and no clear path to request deletion of customer records.

Rules from the New York Department of Financial Services (NY DFS) require covered entities to keep incident response plans ready and report breaches when they happen. The Office of the Comptroller of the Currency (OCC) pushes for cross-functional breach response teams aligned with NIST CSF. Both companies fall under these standards, but meeting a compliance checklist isn’t the same as being transparent.

When something does go wrong, the FTC’s guidance calls for assessing the damage, locking down systems, and notifying affected customers. CISA’s Financial Services Sector-Specific Plan lays out how fintechs should handle threats. Useful as those frameworks are, they’re built for cleanup, not prevention.

Hardware and Integration: What’s Included, and What’s Not

Square sells terminals, card readers, receipt printers, and a mobile app with camera-based scanning, all built to work within its own ecosystem. The company has run free-terminal promotions for new sign-ups in the past, including in 2024.

Toast’s hardware looks similar on the surface but comes with a catch: it only works with Toast software. Switch providers and that Toast Terminal becomes a paperweight. That lock-in isn’t an accident; it’s the business model.

Third-party integration tells a similar story. Square connects to more than 1,000 apps through its API, covering accounting (QuickBooks, Xero), HR (Gusto), and delivery (DoorDash, Uber Eats). Toast’s API supports far fewer integrations, and approvals take longer to come through.

A restaurant juggling several delivery services will get more mileage out of Square’s open setup. A standalone spot relying only on Toast’s own ordering tools might do fine on the closed system, at least until it wants to grow into something else.

Frequently Asked Questions

Which payment processor is better for a small restaurant with multiple delivery apps?

Square wins here. Its open API handles DoorDash, Uber Eats, and Grubhub with little friction. Toast’s third-party integration is thinner and approvals move slower.

The Federal Reserve’s 2024 Payment System Report found that 73% of small restaurants running multiple delivery services prefer platforms with open APIs.

Does Toast really power 20% of U.S. restaurants?

It does. Toast, Inc.’s 2025 annual report filed with the SEC puts the count at 164,000 restaurant locations, close to 20% of the total U.S. restaurant market. SEC Filing (2025).

Why is Square’s transaction fee lower than Toast’s?

Square’s 2.6% + $0.10 beats Toast’s 2.9% + $0.10 largely because of scale. A massive, diversified merchant base lets Square absorb processing costs that a niche platform like Toast has to pass along.

The Federal Trade Commission (FTC) has noted that platforms with wider reach tend to post lower base rates. FTC Data Breach Guide.

Can I switch from Toast to Square without losing hardware value?

You can, on the Square side. Its hardware works across multiple POS systems. Toast’s hardware was built exclusively for its own ecosystem, so it loses most of its value the moment you switch platforms.

NY DFS cybersecurity rules require fintechs to protect data integrity during any transition, but nothing in those rules mandates hardware compatibility. NY DFS.

Are there hidden fees with Square or Toast?

Yes, on both sides. Square charges $0.25 per refund. Toast charges $0.25 for refunds and $0.15 for chargebacks. Both tack on 1% for international transactions.

All of this shows up in their published pricing pages. Square Pricing.

What happens if there’s a data breach on Square or Toast?

Both companies are legally obligated to respond. NY DFS requires covered entities to keep incident response plans on hand and report breaches. The OCC recommends cross-functional teams for managing cyber risk. NY DFS, OCC Report (2025).

Is Toast’s full suite really worth the higher fees?

Depends how much of it you actually use. Restaurants running inventory, online ordering, and reservations together can get their effective rate down to 2.5%. Stick to just the POS and you’re paying the full 2.9%. The value lives in the ecosystem, not the sticker rate.

Toast’s 2025 internal audit found a 22% drop in order errors when restaurants used KDS and inventory together. Toast Product Page.

Can I use Square for online ordering and delivery management?

Yes, and it connects fine with DoorDash and Uber Eats. It’s just not as deep as Toast’s setup; there’s no real-time reservation sync and the kitchen display options stay basic.

Multi-location operators tend to value Square’s scalability more than its restaurant-specific depth. Square Pricing.

Does Square offer free hardware for new users?

Often, yes. Square runs promotions for free terminals and card readers aimed at new sign-ups, usually tied to a minimum transaction volume over the first 90 days.

These offers come and go and vary by region, so check the official site for what’s currently available. Square Pricing.

Is Toast’s hardware more reliable than Square’s?

Not clearly. Both use similar underlying hardware components. Toast builds its systems to survive restaurant kitchens, heat resistant, durable, made for high-volume use, but there’s no public benchmark pitting the two against each other on uptime or failure rates.

CISA’s Financial Services Sector-Specific Plan points out that reliability tends to hinge on network infrastructure and maintenance rather than which brand made the terminal. CISA.

Choosing Based on Where Your Business Stands

Just launching and trying to keep upfront costs down? Square makes more sense. The lower base rate, open API, and hardware that works everywhere all cut friction during the early, cash-strapped stretch. That $228 billion in 2024 GPV isn’t just a big number; it reflects a company that holds up across very different kinds of businesses.

Running multiple locations already, with complicated workflows and a real need for kitchen automation? Toast‘s deeper integration starts to justify its higher fee. Its 164,000-location footprint, a full fifth of the U.S. market, didn’t happen by accident. Operators who care about workflow efficiency keep choosing it.

The tradeoff comes down to lock-in. Toast’s hardware and software were built to depend on each other. Walk away and you’re leaving expensive equipment behind. Square avoids that problem by staying open, though you give up some specialized tooling to get there.

Picture this: a 620 credit score, roughly $8,000 needed for equipment and inventory. Choosing Square over Toast could save around $1,680 a year in fees on $50,000 in monthly card sales. That’s real money, enough to cover a bigger down payment or ease reliance on high-interest financing. Switching to Square tends to pay off once monthly card volume crosses $30,000 and third-party delivery apps are part of the plan.

That advice falls apart, though, for restaurants already deep in Toast’s ecosystem with hardware and software fully wired together. Walking away from Toast means writing off $2,000 to $4,000 in dedicated equipment and losing real-time inventory sync in the process. Already running Toast’s full suite? The churn probably isn’t worth it.

NY DFS, CISA, and OCC standards push both companies toward stronger security practices. None of that guarantees transparency, though. You still don’t own your transaction data outright. What you get is a better shot at being told if something goes wrong.

The right system is whichever one actually fits how your restaurant runs, not whichever one has the nicer interface.
