Stripe vs PayPal vs Square: Best Payment Processor for Your Online Store
Stripe, PayPal, and Square all let your online store accept payments. But each is built for very different E-Commerce & Online Selling businesses. Picking the wrong one costs you in higher fees, lost sales at checkout, and missing important tools. Here's how to choose the one that fits what you're actually building, whether it's your first Shopify store, an Etsy shop, or scaling from Facebook Marketplace.

The quick answer
Stripe wins for dedicated online stores, Shopify users, and businesses selling digital products or subscriptions. Square wins for online sellers who also do local pick-ups, pop-up markets, or craft fairs. PayPal wins when selling on Etsy or if many of your online customers expect to use their PayPal balance.
Side-by-side breakdown
Stripe: 2.9% + 30 cents per transaction online. Offers best-in-class tools and deep integration for Shopify and custom e-commerce websites. Supports subscription box services, digital product sales, and invoicing natively. Requires some technical setup for advanced custom checkout flows, but offers easy plug-and-play integrations for platforms like Shopify.
PayPal: 3.49% + 49 cents for standard online checkout. Has strong brand recognition, especially with older online shoppers and international buyers, which is useful for Etsy sellers. Easy setup with no coding required for any online store. However, its checkout redirects can sometimes cause shoppers to leave your online store before buying.
Square: 2.9% + 30 cents online (via Square Online Store), 2.6% + 10 cents in-person. Offers a free online store builder (Square Online) and free card readers for in-person sales. Excellent for online sellers who also do local product pickups, craft markets, or pop-up events. Less powerful for complex subscription or digital-only product businesses compared to Stripe.
When to choose Stripe
Choose Stripe if you're launching a Shopify store, selling digital courses, managing a subscription box business, or need strong control over your online checkout process. Stripe's deep integrations with e-commerce platforms and its developer tools allow for highly customized shopping experiences. Its billing and revenue recovery tools (like automatic card retries for failed subscription payments) pay for themselves by reducing lost revenue from online memberships or recurring sales.
When to choose Square
Choose Square if you're transitioning from platforms like Facebook Marketplace to a real business, and plan to do local pickups, or if you sell your products at craft fairs, flea markets, or pop-up events in addition to your online store. The free Square Online Store builder is a simple way to get online, and the free card reader works seamlessly for taking credit card payments for local deliveries or at your vendor booth without needing separate hardware.
The verdict
Most new online-only businesses (especially those on Shopify or with a custom website) should start with Stripe. Its lower online fees and powerful e-commerce tools are hard to beat. Add PayPal as a secondary checkout option if your customer base expects it—conversion data shows 5-15% of online buyers (especially on Etsy or internationally) prefer to use their PayPal balance. Use Square only if a significant part of your online business involves in-person transactions or you want a simple, integrated solution with Square Online.
How to get started
For a Shopify store or custom e-commerce website, create a Stripe account at stripe.com. You can have a payment link live or integrate with your platform in under 10 minutes. Run a $1 test transaction to yourself before your first real customer to ensure everything works. If you sell on Etsy, enable PayPal directly through your Etsy seller settings. If you need in-person payment capability for local pickups or events, order the free Square reader and set up your item catalog before your first event or appointment.
