Stripe and Square are the two most recognisable names in modern payment processing, but they were built for fundamentally different businesses. Stripe is an online-first developer platform that powers checkout flows, subscriptions, and marketplaces for software businesses worldwide. Square is a point-of-sale company that started with a card reader for small merchants and grew into a full retail and restaurant operating system. Many businesses can use either — but the right choice depends almost entirely on whether your sales happen primarily online or in person.
The Short Answer
Choose Stripe if your sales happen online — e-commerce, SaaS subscriptions, marketplaces, mobile apps, or any flow where customers enter card details on the web. Stripe's API, documentation, and product surface are unmatched for software businesses. Choose Square if your sales happen in person — retail, restaurants, salons, services, or pop-up events where you swipe, tap, or insert cards on a hardware terminal. Square's integrated POS hardware, free entry-level software, and immediate next-day deposits make it the easiest path to taking card payments at a physical location.
Pricing: Same Headline, Different Reality
Both platforms charge 2.9% + 30¢ for online card transactions, which makes them appear identical on paper. The reality is more nuanced. Square charges 2.6% + 10¢ for in-person tap, dip, and swipe — meaningfully cheaper than Stripe Terminal's 2.7% + 5¢ once volume is taken into account. Stripe offers volume-based discounts and custom pricing for businesses processing over $80,000 per month, which Square does not advertise. Square charges 3.5% + 15¢ for manually keyed transactions; Stripe is similar but allows risk-based pricing tiers. For most small businesses, the headline rates are what apply.
Hardware and In-Person Payments
Square's hardware is its core differentiator. The free magstripe reader, $49 contactless reader, $299 Square Terminal, and the Square Register make it possible to accept card payments at a physical location within a day of signing up — no separate gateway, processor, or POS software contract required. The same Square account powers e-commerce, invoices, and recurring billing. Stripe Terminal exists but is positioned as an API for software platforms that want to embed in-person payments into their own apps; it requires development work to deploy and is not aimed at standalone merchants.
Developer Experience and APIs
Stripe is widely adopted for payment APIs. The documentation, SDKs (in roughly a dozen languages), test mode, hosted UI components (Stripe Elements), and broader product surface — Billing, Connect, Issuing, Atlas, Tax, Radar — are designed for software teams that want to embed payments deeply into their product. Square also has APIs and they have improved over time, but the ecosystem is smaller and the documentation is less developer-focused. For a software-first business, Stripe is typically the default choice.
Subscriptions, Marketplaces, and Advanced Use Cases
Stripe Billing is one of the most mature subscription platforms available — managing recurring charges, trials, proration, dunning, tax, and customer portals through a single API. Stripe Connect powers marketplace payments and split-fund routing for platforms like Shopify, Lyft, and DoorDash. Square offers subscriptions and invoicing through Square Online and Square Invoices, but the products are designed for service businesses (yoga studios, gyms, consultants) rather than software platforms. For SaaS, marketplaces, and platform businesses, Stripe wins decisively. For service businesses billing local clients, Square is more than enough.
Who Each Processor Is Best For
Choose Stripe if you run an online business, are a software company embedding payments, operate a marketplace or platform, or need advanced billing features like proration and revenue recognition. Choose Square if you run a physical retail or restaurant business, want POS hardware and software bundled in one account, are a service-based business sending invoices and accepting in-person payments, or value Square's ecosystem of restaurant tools (Square for Restaurants), retail tools, and payroll integration. A small but growing number of hybrid businesses use both — Stripe for the website, Square for the storefront.
Key Takeaways
- Stripe is online-first; Square is in-person-first — the right choice depends on where your sales happen.
- Headline online rate is identical (2.9% + 30¢), but Square is cheaper for in-person and Stripe offers volume pricing.
- Square's integrated POS hardware is its biggest advantage for physical retail and restaurants.
- Stripe's API, documentation, and developer ecosystem are the strongest in the industry for software businesses.
- Hybrid businesses (online + physical) sometimes run Stripe and Square in parallel rather than choosing one.

How to Choose a Platform
- If you sell online and have any developers on the team: Stripe. The integration time savings are worth more than the marginal feature differences.
- If you sell in person and don't have engineers: Square. Sign up online, hardware arrives in two days, you are taking payments by the weekend.
- If you run subscriptions, marketplaces, or platforms: Stripe. The Billing and Connect products are years ahead of Square's equivalents.
- If you run a restaurant or retail store: Square. The vertical-specific tools (Square for Restaurants, Square for Retail) are built for the workflows and have no Stripe equivalent.
- If you process more than $80k/month: contact Stripe sales for volume pricing — published rates are not the rates large merchants pay.
Frequently Asked Questions
Are Stripe and Square fees actually the same?
For online card transactions, yes — both charge 2.9% + 30¢. The differences appear in adjacent products. Square is cheaper for in-person transactions (2.6% + 10¢ vs Stripe Terminal's 2.7% + 5¢ at smaller volumes). Stripe negotiates custom rates for businesses processing over roughly $80,000 per month; Square is more rigid on pricing. International card fees, currency conversion, and chargeback fees also differ — review the full pricing page for both before committing.
Can I use Stripe for in-person payments?
Yes — Stripe Terminal is an API and SDK that lets developers integrate in-person card readers into their own software. It supports BBPOS chip readers and Verifone terminals. The catch is that Stripe Terminal is built for platforms (a restaurant POS company, for example) that want to embed Stripe behind their own product. It is not a turn-key product for individual merchants. If you are a single small business that wants to take cards at a counter, Square is dramatically faster to set up.
Which is better for a Shopify or WooCommerce store?
Both work with Shopify and WooCommerce. Stripe is the more common default and integrates more deeply — Shopify Payments is itself built on Stripe infrastructure for most merchants. Square also has plugins for both platforms, but the integration is shallower and the dispute and chargeback workflows are weaker than Stripe's. For an e-commerce-only business, Stripe is the more common default. The exception is hybrid businesses already on Square for in-person sales who want a single dashboard.
Do Stripe and Square integrate with accounting software?
Both integrate with QuickBooks, Xero, and most major accounting platforms — either through native integrations or through Plaid and similar data aggregators. Square's integration is generally tighter for small businesses because the merchant data structure is simpler. Stripe integrates well but exposes more granular data (fees, refunds, disputes, payouts) that requires more configuration to map cleanly to a chart of accounts. For larger businesses, expect to do some setup work in either case.
