Stripe overview
Stripe is the developer's payment platform. It powers online payments for millions of businesses from startups to enterprises like Amazon, Google, and Shopify. Its API-first approach means developers can build virtually any payment experience.
Stripe processes hundreds of billions of dollars annually. Its product suite extends beyond payments into billing, invoicing, tax compliance, fraud prevention (Radar), and treasury services. If you are building a SaaS platform, marketplace, or subscription business, Stripe is the default choice.
Square overview
Square (now part of Block, Inc.) democratized card payments for small businesses. Its free card reader and simple POS system let any retailer, restaurant, or service provider accept card payments with zero upfront investment.
Beyond payments, Square offers a complete business platform: POS hardware, inventory management, staff scheduling, payroll, and an online store builder. Square Banking provides business checking and savings accounts with instant deposit access.
Feature comparison
Online Payments
Stripe dominates online payments. Its checkout integration takes minutes for developers, and the API supports complex scenarios like metered billing, marketplace splits, and multi-party payments. Stripe Elements provides pre-built UI components that handle PCI compliance automatically.
Square Online offers a simpler checkout that works without development expertise. It integrates with the Square ecosystem but lacks the flexibility for custom payment flows.
In-Person Payments
Square is the clear winner for in-person payments. Its hardware lineup includes the free magstripe reader, $49 contactless reader, $149 Stand, $299 Terminal, and $799 Register. The POS software is free and handles inventory, receipts, and tipping.
Stripe Terminal exists for in-person payments but requires development work to implement. It is designed for businesses that need unified online and offline payment processing through a single API.
Subscription Billing
Stripe Billing handles complex subscription scenarios: usage-based pricing, tiered plans, free trials, proration, and dunning management. It is the standard for SaaS billing.
Square Subscriptions is more basic - it handles recurring payments but lacks the flexibility for complex pricing models.
Pricing breakdown
Stripe charges 2.9% + 30 cents per online transaction. In-person transactions via Terminal cost 2.7% + 5 cents. There are no monthly fees - you pay only per transaction.
Square charges 2.6% + 10 cents for in-person transactions and 2.9% + 30 cents online. The basic POS software is free; Square Plus starts at $29/month per location for advanced features.
Our verdict
Choose Stripe if you are building an online business, SaaS product, or marketplace that needs flexible payment infrastructure. Its developer tools and global reach are unmatched.
Choose Square if you run a retail store, restaurant, or service business that needs in-person payment processing with a complete POS system. The free entry point and all-in-one approach make it ideal for brick-and-mortar businesses.
