Stripe vs Square for Online Payments

Fee Comparison

Stripe and Square charge identical rates for standard online card transactions: 2.9% + 30 cents per transaction. The fee parity ends there. Stripe charges 3.9% + 30 cents for international cards, plus 1% for currency conversion. Square does not support multi-currency processing for most merchants, so international fees are less of a factor, but also less of an option.

For in-person payments, Square charges 2.6% + 10 cents per tap, dip, or swipe. Stripe Terminal charges 2.7% + 5 cents per in-person transaction. Square's in-person rate is slightly higher per transaction but comes with a more mature hardware ecosystem and a simpler setup experience. Manually keyed transactions (where you type in a card number) cost 3.5% + 15 cents on Square and 3.4% + 30 cents on Stripe.

Neither processor charges monthly fees for the basic product. Square's paid plans (Square Plus at $29/month, Square Premium at $79/month) add features like advanced team management, loyalty programs, and advanced reporting. Stripe's additional products, like Stripe Tax, Stripe Billing, and Stripe Radar for Fraud Teams, are priced per transaction or per usage rather than as monthly subscriptions.

Online Payment Features

Stripe was built for online payments from the ground up. Its product suite includes Stripe Checkout (a pre-built hosted payment page), Payment Elements (embeddable payment form components), Payment Links (no-code shareable payment URLs), Stripe Billing (subscription management with dunning, proration, and metered billing), Stripe Connect (multi-party payments for marketplaces), and Stripe Invoicing. Each product has a polished API and pre-built integrations with major platforms.

Square's online payment tools are simpler. Square Online provides a basic ecommerce website builder with built-in payments. The Square Web Payments SDK lets developers embed payment forms in custom websites. Square Invoices handles billing for service businesses. Square Subscriptions exists but is basic compared to Stripe Billing, lacking features like metered billing, usage-based pricing, and multi-tier subscription management.

For online-only businesses, Stripe offers significantly more functionality. Subscription businesses, SaaS companies, marketplaces, and platforms will find that Stripe has purpose-built tools for their use case, while Square's online tools are designed primarily for retailers who also happen to sell online.

In-Person Payment Hardware

Square dominates the in-person payment hardware market for small businesses. The hardware lineup includes the Square Reader for magstripe (free with your first order), the Square Reader for contactless and chip ($49), the Square Stand for iPad ($149), the Square Terminal ($299), and the Square Register ($799). All hardware connects to the Square POS app, which runs on iOS and Android. The POS app is free and handles sales, inventory tracking, customer management, and basic employee management.

Stripe Terminal is newer and more limited. It supports the BBPOS WisePOS E ($249) and BBPOS Chipper 2X BT ($59) readers, along with several other certified devices. Stripe Terminal is designed for developers building custom POS experiences, not for merchants who want a plug-and-play countertop solution. You need to integrate Terminal through Stripe's API or use a pre-built POS application that supports Stripe Terminal.

If in-person sales are a meaningful part of your business, Square is the clear winner. The hardware is affordable, the POS app is polished, and the setup requires zero technical knowledge. Stripe Terminal is a developer tool that happens to accept in-person payments, while Square is a payment system built around the in-person experience.

Ecommerce Platform Integrations

Stripe integrates natively with virtually every major ecommerce platform. Shopify Payments is powered by Stripe. WooCommerce Payments is powered by Stripe. BigCommerce, Squarespace, Wix, and nearly every other platform offer Stripe as a first-class payment option. When you choose an ecommerce platform, Stripe integration is almost always available out of the box.

Square's ecommerce integrations are more limited. Square works with WooCommerce through an official plugin, and with BigCommerce through a third-party integration. It does not integrate natively with Shopify because Shopify has its own competing payment system. Square's strongest ecommerce integration is with its own Square Online platform, which is a basic but functional website builder included free with every Square account.

If you already use a major ecommerce platform like Shopify, WooCommerce, or BigCommerce, Stripe is almost certainly better supported. If you want a simple online store built into your payment system, Square Online is a viable option for businesses with straightforward needs.

Reporting and Analytics

Stripe's dashboard provides detailed reporting on payments, refunds, disputes, revenue, customer lifetime value, and more. Stripe Sigma lets you run custom SQL queries against your payment data. The reporting is deep enough for finance teams at large companies but organized well enough for solo founders.

Square's dashboard is designed for accessibility rather than depth. It shows sales summaries, top-selling items, customer visit frequency, labor costs (if you use Square's team management), and basic trends. The reports are easy to read and useful for daily operations, but lack the granularity that data-driven ecommerce businesses need. Square's advantage is unified reporting across online and in-person sales, which Stripe only provides if you use both Stripe's online and Terminal products.

Developer Tools

Stripe is the gold standard for payment APIs. The documentation is comprehensive, the SDKs support seven programming languages, the CLI enables local testing, and the community of developers building on Stripe is massive. If you are building a custom application, a platform, or anything that requires programmatic payment control, Stripe is the default choice.

Square's APIs are solid and improving. The REST APIs cover payments, catalog, inventory, customers, and orders. The documentation is clear and the SDKs support popular languages. But the API surface area is smaller than Stripe's, and fewer third-party tools and libraries are built around Square's APIs. Square's developer tools are good enough for most integrations but lack the depth and ecosystem that Stripe offers.

Account Stability

Both Stripe and Square operate as payment facilitators, which means your account operates under their master merchant account. Both companies reserve the right to freeze funds or terminate accounts that violate their terms of service or trigger automated risk alerts. However, their reputations differ.

Square has a well-documented history of sudden account terminations, particularly for businesses in categories that Square's risk algorithms flag as problematic. Sellers of firearms accessories, CBD products, supplements, and certain service businesses have reported accounts shut down with funds held for 90 days or more. Stripe's account stability is generally better, though not perfect. Stripe tends to communicate more clearly about compliance issues and provides more warning before taking action.

For either platform, the best protection is to keep detailed records, maintain low chargeback rates, respond to disputes promptly, and ensure your business type aligns with the processor's acceptable use policy.

When to Choose Stripe

Choose Stripe if your business is primarily online, you use a major ecommerce platform like Shopify or WooCommerce, you need subscription billing or marketplace payment splitting, or you want the most flexible and well-documented payment API available. Stripe is the better choice for SaaS companies, online-only retailers, digital product sellers, and developers building custom payment experiences.

When to Choose Square

Choose Square if you sell both online and in person, you want affordable POS hardware with zero setup complexity, you run a restaurant, retail store, or service business with a physical location, or you want a simple all-in-one solution that includes a free online store, invoicing, and appointment scheduling. Square is the better choice for brick-and-mortar businesses that also sell online, farmers market vendors, food trucks, and solo service providers.

The Bottom Line

Stripe and Square charge the same rate for online transactions, but they serve different business types. Stripe is built for the internet. Square is built for the counter. If your sales are primarily online, Stripe gives you more tools, better integrations, and a stronger developer ecosystem. If your sales mix includes significant in-person volume, Square's unified commerce approach saves you from juggling separate online and offline systems.
