Choosing the right payment processor is one of the most important decisions for any business. Stripe and Square are both industry leaders, but they serve different needs. Stripe dominates online payments with developer-friendly tools, while Square excels at in-person transactions with its point-of-sale hardware. This comparison covers fees, features, and use cases to help you decide.

Online Payment Processing
Stripe is the gold standard for online payments. Its API is widely considered the best in the industry, powering businesses from startups to enterprises like Amazon and Shopify. Stripe supports 135+ currencies, advanced fraud detection with Radar, subscription billing, and virtually every payment method including cards, wallets, bank transfers, and buy-now-pay-later options. Square offers online payment processing that works well for simpler needs but lacks the depth and flexibility of Stripe's developer tools. For businesses where online payments are the primary revenue channel, Stripe is the clear choice.
In-Person and Point of Sale
Square was built for in-person payments and it shows. The Square ecosystem includes free card readers, countertop terminals, and full register systems. Square POS software handles inventory, employee management, appointment booking, and customer loyalty programs at no additional cost. Stripe has no POS hardware of its own and is not designed for brick-and-mortar retail. If your business involves face-to-face transactions, Square's integrated hardware and software solution is far superior.
Fees and Pricing
Standard processing fees are nearly identical for online transactions at 2.9% + $0.30 per transaction. For in-person payments, Square charges 2.6% + $0.10 while Stripe charges 2.7% + $0.05. The differences are marginal for most businesses. Where costs diverge is in add-on features — Stripe's premium tools (Radar for Fraud Teams, Stripe Tax, Atlas) carry additional fees, while Square bundles many business tools into its free tier. Use our Pricing Calculator to model your total processing costs based on your sales volume.
Invoicing and Business Tools
Both platforms offer invoicing, but they approach it differently. Square provides a polished invoicing tool with payment tracking, automatic reminders, and a free tier. Stripe also supports invoicing through its dashboard and API but targets it more at developers and SaaS businesses. Square adds a free online store builder, appointment scheduling, and payroll services, making it a more complete small business platform. Use our Invoice Generator Pro to create professional invoices alongside either processor.
Who Should Choose Stripe?
Stripe is the right choice for online-first businesses, SaaS companies, marketplaces, and developers who need maximum flexibility and control over their payment infrastructure. If you process payments internationally, need subscription billing, or require deep API integration, Stripe is unmatched.
Who Should Choose Square?
Square is ideal for retail stores, restaurants, service businesses, and anyone who needs in-person payment processing with minimal setup. Its free POS software, hardware ecosystem, and bundled business tools make it the easiest way to start accepting payments in a physical location.
