Yes — many businesses use both simultaneously. Square handles in-store POS and hardware payments while Stripe powers the online store checkout. The two platforms can operate independently for different sales channels.
For in-person payments, Square (2.6% + $0.10) is slightly cheaper than Stripe (2.7% + $0.05) for smaller transactions. For online payments, both charge 2.9% + $0.30. Stripe offers custom pricing (typically lower) for businesses processing over $1M/year.
Square does support online payments through Square Online (free website builder with e-commerce) and a basic API, but Stripe is significantly more powerful for custom online checkout, recurring billing, and marketplace payment flows. Square Online is best for existing Square brick-and-mortar sellers adding an e-commerce channel.
Square dominates restaurant payment processing. Square for Restaurants offers table management, floor plans, coursing, kitchen display systems, and a complete restaurant POS — all included. Stripe has no restaurant-specific POS tools.
Analysis: Stripe vs Square
Square (now part of Block, Inc.) and Stripe are the two most recognizable names in modern payments infrastructure, but they have evolved to serve different primary audiences: Square is built for physical and omnichannel merchants who need POS hardware plus software; Stripe is built for developers and online businesses who need API-first payment infrastructure. By 2026, both have expanded significantly beyond their original core, creating meaningful overlap — but their DNA remains distinct.
Square: Founded 2009 by Jack Dorsey and Jim McKelvey, Square's original insight was the hardware dongle that turned an iPhone into a card reader. The 2026 Square ecosystem is far broader: Square Terminal ($299, countertop POS), Square Register ($799, full touchscreen POS), Square for Restaurants, Square for Retail, Square Appointments, Square Online (website builder with integrated payments), and Square Payroll. Square's flat 2.6% + $0.10 per swipe pricing (for card-present transactions) is predictable for small businesses but not the cheapest option at scale. Square's key advantages: no monthly fee, rapid merchant onboarding (accepting payments in 30 minutes), free basic POS software, and a tightly integrated ecosystem where hardware, software, payments, and business management tools share the same data layer. Square's weakness: international availability is limited (US, Canada, Japan, Australia, UK, Ireland, France, Spain), and API customization depth is significantly shallower than Stripe for complex use cases.
Stripe: Founded 2010 by Patrick and John Collison, Stripe's core thesis was that payment infrastructure was unnecessarily complex and that a well-designed API could collapse the integration time from months to days. Stripe processes approximately $1 trillion in annual payment volume. Pricing: 2.9% + $0.30 per successful card charge for online payments (with custom pricing for enterprise volume). Stripe's product suite in 2026: Stripe Payments (core API), Stripe Connect (marketplace and platform payments), Stripe Billing (subscription management), Stripe Terminal (hardware POS that extends Stripe online to in-person), Stripe Radar (ML-based fraud detection), Stripe Identity (ID verification), Stripe Tax, Stripe Issuing (virtual and physical card creation), and Stripe Treasury (banking-as-a-service). Stripe operates in 47+ countries — dramatically broader than Square's footprint. For software companies building platforms, marketplaces, SaaS products, or anything with complex payment flows, Stripe's Connect product and API flexibility are effectively unmatched.

The 2026 choice: Square wins for brick-and-mortar and omnichannel SMBs that want integrated POS hardware, no monthly fees, and easy onboarding without developer resources. Stripe wins for online businesses, developer-led companies, platforms, marketplaces, and any organization that needs payment customization, multi-currency support, or operates across multiple countries. Companies that start on Square sometimes migrate to Stripe as they scale; the reverse migration is rare because Stripe's capabilities exceed Square's as complexity grows.
