Stripe vs Square for online checkout

If you mean online checkout for a website/app, the short version is:

• Stripe is usually the better choice for custom online checkout, subscriptions, marketplaces, and international payments.
• Square is usually better if you want simple setup, especially if you also use in-person POS or already run a retail business.

Quick comparison

Stripe

Best for:

• Custom checkout flows
• SaaS / subscriptions
• Marketplaces and platforms
• Global payments
• Developer-friendly integrations

Pros:

• Very flexible
• Excellent APIs and documentation
• Strong support for subscriptions, invoices, saved cards, fraud tools
• Works well with many payment methods and currencies

Cons:

• More technical setup if you want a highly custom flow
• Support can feel less hands-on for small businesses

Square

Best for:

• Small businesses
• Simple ecommerce
• Businesses that also do in-person sales
• Fast setup with less development

Pros:

• Easy to get started
• Good all-in-one ecosystem for POS + online
• Simple dashboard and reporting
• Nice for local/small business use cases

Cons:

• Less flexible for advanced online checkout needs
• Not as strong as Stripe for complex subscription/platform use cases
• Generally less developer-friendly

Choose Stripe if:

• You need a fully custom checkout
• You sell digital products, SaaS, or memberships
• You want to support multiple currencies/countries
• You may build a marketplace later

Choose Square if:

• You want to launch fast with minimal setup
• You already use Square for in-store payments
• You run a small business and want simplicity over flexibility

Rule of thumb

• Ecommerce store / SaaS / app: Stripe
• Local business / simple shop / POS + online: Square

If you want, I can also compare them on fees, subscriptions, ease of integration, or international payments.
